Lab Rat by AnonymousThis past summer was an incredibly fascinating one. One that I willalways remember.I work at home doing consulting for Internet companies and got to knowmy neighbors very well for thepast 5 years. They are mid forties and seem very normal andconservative. He is a manager for a smallpharmaceutical company and she is a clinical nurse. She has beenstudying to become a sexual therapyspecialist and there starts my story.Early in June they asked me over for a Friday night swim which wasn'tunusual. After dinner and a fewdrinks we were relaxing in the shallow end of the pool when David says"Well, Paula, you may as well askhim right out."Paula is a petite woman, not at all unattractive but not a 'babe' by anymeans. She is athletic, withclose trimmed hair and wears glasses most of the time. She looks like aclinical nurse...Paula blushed and sort of stumbled with her words and then said "I havea final paper to write and I waswondering if you would be a subject. I have recruited 3 guys from theschool, but I need an older man tomake the data complete." David sort of chuckled and I asked what elsethere was to the request."It's about, the paper is about, well, uh, masturbation." Paula nevertook her eyes off of mine and shetried to appear as clinical and professional as possible. Dave justlaughed and said "Well, old man,here's your chance for immortality.""Why don't you use Dave", I asked, a little nervous and somewhatshocked."Well I can't because he's a family member and that would skew theresults. The other guy had tocancel at the last minute and the study starts Tuesday. We are reallyin a bind and need to get someoneby Monday. Could you, or would you consider it. It's strictly science.""We? Who's we?" I looked at David and he laughed and swam away. "Paula,you gotta tell him everything,"he laughed a little more."Cindy is my partner in the clinical part," Cindy continued, "She's verynice and very professional. Thestudy will only last 8 weeks as we are only doing student research.""David, what do you think?" I asked."Hey, man, it's your choice. I can't help you in this decision."Now, I love to jerk off and have been doing it for years, but this wasreally exciting. Now, how do Isay yes without sounding like a pervert?"Well, I guess I can help out. What do I need to do?""Great," Cindy exclaimed. "Oh, by the way, the University will send you$100 for participating.""Ok," I laughed nervously, "What do I have to do?""We are studying the male libido and sex drive as it pertains tomasturbation," Paula started. "We willgive you a series of questions before and after you go through theexercises. Then we compare theanswers and actions immediately following orgasm and again thirtyminutes later.""Where does this happen," I asked, my mouth getting dry and my dickgetting hard?"At Cindy's house. She has a large Rec Room that will be perfect. We canget all four subjects there atone time without having any distractions."David laughed loudly then, "Hey, you're now an official subject."We all chuckled at that and the night went on without incident.Monday morning Paula called and asked if she could bring Cindy over tomeet me and we could discuss theupcoming meeting and explain a little more about what would behappening.Cindy was a bit younger, about mid thirties and slightly better lookingthan Paula, with the sameathletic body and short hair, but a little more feminine cut. She wasalso tall. About 5'10" or so.She introduced herself and we talked briefly about working at home andnursing and stuff and then shesaid, "We really appreciate this and I hope embarrassment will be not bea problem. We will keepeverything as professional as possible. The others have done this sortof thing before, working forstudies that is, so they may feel a bit more relaxed."I started to wonder what was going on when they explained that we wouldbe nude and asked to masturbatewith several techniques while they study the effects of differentstimuli."First night will be solo, the second with everyone at the same time,third and forth solo and the restas a group again," Cindy stated matter-of-factly."You mean I have to masturbate in front of you and other men too," Iblurted out?Cindy turned and looked at Paula and said, "You didn't explain thisyet?"Paula looked at me with pleading eyes and said, "Please, Jeff, it wontbe so bad. It's a professionalstudy and we are professionals."I was getting a hard-on the size of the state of Maine, so I excusedmyself and headed for the kitchen."Let me get a drink," I said over my shoulder, "Can I get you anything?"No we have to be getting to class," Paula said. "Will you still behelping us?"My voice was dry as hell, but I stammered out, "Yeah, uh, sure. Iguess."What commitment.Tuesday, Session 1I arrived at 7:30 and was introduced to 'Subject 3' as he was leaving.Subject 3 was an intern at thehospital and about 29 - 34. Tall, good build and very cordial. Bothwomen were wearing sweat suits andathletic shoes. They looked like typical soccer moms.After he left, we sat down to talk. I answered question after questionabout sex, my likes and dislike,how often I masturbated, what stimulated me, have I ever participated inhomosexual experiences etc...For about 30 minutes the questions were rapid fired to me and recordedon the small tape recorder thatsat in the middle of the coffee table.I told them that I would masturbate once or twice a week (I lied - tooembarrassed to say that I didalmost daily), that I liked to watch porno films and that no, I hadnever experienced homosexual sex."Have you ever fantasized having oral sex with a man," Cindy asked?"No""Have you ever fantasized being anally raped?""No.""Have you ever fantasized watching another man be anally or orallyraped?""No, well, uh, yeah, I guess the oral part."My dick was so hard I thought it was gonna burst."We need to start the clinical part now," Cindy said as she stood up."Jeff, please step to the cornerand disrobe."I was so embarrassed that I already had a hard-on that I didn't knowwhat to do. The women just wrotenotes and I sat in the easy chair and folded my hands on my lap."What is your normal technique," asked Paula as I was gettingcomfortable?I took my erect penis between my thumb and three fingers and showed themhow I handled my cock.They wrote and compared notes.Cindy popped in a porno tape and they asked me to begin."Please let us know when you are about to ejaculate. We would like tomeasure your semen and get asample of the size of your normal amount."Paula wrote as Cindy turned around with a video camera and focused on mymid-section.While I'm stroking away, they began with a barrage of questions. Similarto the first round they focusedon what I wanted to do, what turned me on, and whether I wanted tocommit homosexual acts with willingand unwilling partners.When they started talking about having oral sex with men, the tapestarted to intermix blowjobs by womenwith blowjobs by men. "Does this stimulate you? Do you like what he'sdoing? Does she remind you ofsomeone?" On an on, Finally, I grunted something about 'now' and theyput a beaker near my penis. I shota load that was intense. They counted the spurts and then checked thevideo camera to make sure they'got it'.I dressed and they started with the questions again.The session ended with me getting dressed and the women thanking me andassuring me that there wasnothing to be embarrassed about, this was science.Tuesday, Session 2Paula and Cindy were again dressed in sweat suits and tennis shoes, butthis time there were four mensitting nervously in the four chairs lined up in the middle of the room.We made small talk until Cindysaid "Well, guys, let's get started. Remember that this is a process ofdiscovery. We may say or ask youquestion that may embarrass you or be difficult to answer. We need onlycomplete honesty and in no waymean this as a personal situation."We are asked to disrobe and re-sit ourselves in the same chairs as westarted in. We were all verynervous and were trying not to look at each others cocks, but we knewwhat was coming and there was alot of tension in the air."Thanks guys," said Paula, "now we need erections before we cancontinue."We sort of hesitated and each man wanted not to appear eager or thefirst to grab his own cock in frontof so many other men. Subject 2 started and we all quickly followed. Thevideo camera was recording andthe barrage of questions followed. Same questions as before but aimed atdiffering ones of us. We werethen told to synchronize our strokes so that no one was going fasterthan any one else. The pace fell toa medium motion and the questions started to get a slight edge that Ihadn't heard before."Subject 3, do you like the way subject 1 grasps his cock?""Subject 2, do you want to suck any of the other guys in the room?"Subject 4, how would you feel if subject 1 stuck his cock in yourmouth?"Subject 3, describe subject 2's cock."On and on it went, we were perspiring and each man was hard as a rock.The answers were still negativein the homosexual aspect, but the answers were getting slower response.Subject 2 groaned and shot his load on his stomach. Immediately after,subject 1 and I unloaded almostin unison and 30 seconds later subject 3 groaned and shot a huge loadall over his thigh.We were breathing as if we had run a marathon and the women startedpumping the questions again."What do you think of number 3's load?""Have you ever wanted to taste another man's semen?""Describe the man's cock to your left?""Gentlemen, please stay seated while we explain the rules for our nextsession.Paula started to walk around us as she spoke. "Please do not masturbatefor the next 7 days. Do not havesex with your girlfriends and do not drink any alcohol."As she explained this the cum was starting to dry and we were all veryembarrassed as we sat covered incum as this woman explained what we should do for the next week."You may get dressed now," said Paula very flatly.Monday, Session 3Very similar to session 1 except the language was far more sexy and raw.I was asked to masturbate withmy left hand and use a lubricant. About half way into the session I wasordered to stop. The porno tapewas playing and the women started to ask me to describe what it feltlike to get a blowjob. I wasn'tallowed to touch my cock as I told them how I thought it felt. My cockbobbed and danced as I explainedthe sensations to them."Stroke it," barked Cindy and I grabbed the base and started strokinghard."Stop," shouted Paula. "We want you to show us how to give oral sex."A dildo landed on my lap and I started to protest."Do you want to cum," asked Cindy, "then show us how you would do it."I started to suck the dildo and they said to start stroking as I suckedthe rubber dick."Faster," shouted Paula.I groaned and shot a huge load onto my stomach.The women got up from their seat and walked over to where I was sittingand told me to keep sucking thedildo. I gave it a few nibbles and stopped."It's not as exciting now, is it," asked Cindy?"Tell us what it feels like after the ejaculation?"I tried to explain the sensation of embarrassment and less heightenedsexual energy after the orgasm,but I got very embarrassed as I sat there with cum dripping from mystomach and my cock shriveling asthe two women stood very close, writing and whispering to each other.After a while they started talking and I sat there waiting for moreinstructions, but none came. I gotup and dressed. They looked at me and gave me next weeks rules - thesame, no sex.Monday, session 4Again, I was the only subject.The women were dressed in business suits and heels. They were wearingmakeup and looked very sharp andprofessional. And sexier than I had seen them. There was no small talk."Strip!" was the command.I was placed on a gurney and my hands were bound at my side withrestraints.After checking the restraints, Paula walked to the door and said, "OK,Darla, let's get started.A young lady walked into the room wearing only a white teddy and whitehigh heels. Paula introduced heras "Darla" a professional masseuse who had been hired for this part ofthe testing. Darla looked to beabout 20 years old and she sort of snickered as she was told to take herposition.Walking to the back of the gurney, she took my cock in her hands andstarted to massage it, twist it andjerk it in an exquisite manner. She was not gentle. She tugged andtwisted and pounded my cock down tothe balls. It hurt but was exciting at the same time.There was silence for about 15 minutes. Darla would take me to almostorgasm and then stop or squeeze. Iwas literally moaning when the questions started."We want you to suck one of the other guys off," said Cindy, gettingvery close to my head. "We'll letyou choose. Who will it be?"I started to protest but the stroking stopped. I strained to get relief."Who will it be?" said Paula harshly."Number 2," I shouted and the stroking continued, slower now."Show us what you will do to his cock," sneered Paula as she brought therubber dildo over and held itin front of my face. "You can't come until he does. You understand thatdon't you?"I started sucking like crazy as the practiced hand started caressing myballs and stroking fast, slow,fast."Come on now, you can do better than that," sneered Darla as she pumpedmy dick."Number 3 wants to fuck your face. Did you know that? He was practicallybegging to suck you off. Hewanted to stay and do it tonight, but we told him he would have towait."Paula got very close now and said that she was worried about number 1.No matter how much they askedhim, he didn't want to suck any of the guys off."And that disappoints us," whispered Paula. "And when we'redisappointed, you're disappointed."Darla stopped stroking and turned to the women. "This one almost came.Are you sure you don't want me tofinish him off?"Cindy smiled and said, "No, we're finished here. Thank you Darla.""Cool," she quipped and walked out the door.We'll release you in a moment or two, Jeff. Hold on." Paula was back tosounding like her old self, butI was tied to a gurney naked, with my dick waving in the air. The womenput their clipboards on mystomach and legs and began filling out their notes. My cock was inchesfrom their hands, but they didnothing to acknowledge it. I was straining to try to get some relief,but none was to come. After about10 minutes, the women untied me and left the room."Don't touch your penis till next time," Paula shouted into the room."You understand?""Yes," my voice cracked and humble.Monday, session 5We were very tense.Naked we stood in a semi circle and let the women tie our left hands toour sides.They were wearing short shorts and summer tops and strappy sandals. Theylooked really hot.Then Darla came in again and we were amazed at how gorgeous she looked.Wearing only heels, hose and asmall demi bra, she walked to the group."Who wants a blowjob," she asked.We started to speak as one, shouting like animals to choose each of us.The women then announced the rules. The last man left who hasn't cumgets the gorgeous Darla's mouth."Now," said Paula matter-of-factly, "grasp the cock of the man on yourright and stroke."Cindy was writing furiously and making sure the video camera was rollingwhen number 2 grabbed number1's cock and started stroking. Soon all of us were actively stroking theman's cock to our right. Eachtrying desperately not to cum as we tried even more desperately to makethe guy in our hands cum.Meanwhile the women came in close and commented on the stroking,giggling and being very unprofessional.This was a supreme circle jerk and they were really enjoying themselvesas we groaned and pounded eachother's cocks.I had a tight grip on number 4's thick dick, and was pumping like mad. Iwanted that blowjob so bad.But number 2's grip was so warm and he really knew how to jerk a cockthat my hips were bucking inrhythm and that familiar feeling started in my balls and they started totighten.Number 2 let go first and then me and as I was finishing shooting,number 4 shot so hard he hit the guyacross from him.Number three jumped back from the circle, almost knocking Cindy down.His legs were buckling and hemumbled something about Darla's lips.She walked over to him and dropped to her knees. Grabbing hold of hiscock she twisted and slammed itinto her fist a few times bringing her mouth ever closer. Number 3didn't make it though. He came justas she was getting close to blowing him. He spurted into her hand andher hair.She laughed and turned to Paula and Cindy. "I tried," she mocked, "but Ithink these guys like beatingoff more than fucking women."We were humiliated and excited at the same time. No-ones cock hadtotally deflated and most werestanding tall."That's it gentlemen," said Paula. We will take next Monday off for the4th of July and see you backhere in two weeks. And we want you to shave your cocks. Is thatunderstood?"Monday, session 6A very clinical session with wires attached to our foreheads, heart andscrotum. We beat off as a groupand the questions were back to scientific and dry. No mention of suckingother guys off and no mutualmasturbation. The guys seemed genuinely disappointed and the two womenseemed very clinical.No Darla and no mention of the previous meeting. Not a word about ourshaved cocks.Monday, session 7Almost a copy of session 6 and one of the men mentioned the lack ofsexiness.We were standing there in the room with our cocks at full attention asCindy and Paula walked around uswearing the short shorts and halter-tops that made them look so good.We were stroking in unison when number 2 asked what happened to Darla?"Look, guys," Paula said, "This isn't about you getting off. This is ourexperiment. We are trying to dosome research here. If you want a blow job, have one of them do it."The room was quiet until number 3 said. "I'll suck you if you suck me."Cindy smiled and said, "Hey Paula, we have some spontaneous actionhappening here."Paula walked over just as number 3 dropped and started sucking number2's cock like crazy. Number 4 wentover and started sucking number 3's cock like there wasn't anything hewanted to do more.I tried to get into the mix, but there wasn't any room."Why don't you just lay down and take care of each other in a circle."Paula laughed as she spoke.Quick as we could, we arranged ourselves on the carpet and began acircle-suck. It was exhilarating andI relished every moment. I had number 3's fat cock in my mouth whilenumber one gave me a superbsucking.Paula and Cindy walked around us taking notes and pointing outtechnique."Suck those dicks, suck-boys... Slower... Let the cock go all the wayin... suck deep now... use yourtongues... No hands, just suck-boy mouths!We all came in about two minutes, swallowed, and just kept on sucking.Paula was smiling as she comparedwhat she was writing to Cindy's notes. This time we all sucked eachother for over 40 minutes until westarted cumming, one at a time. Paula and Cindy would make us changepartners and I had every cock forawhile. Number 2's cock was so smooth and tapered that it would slidefarther down my throat than Ithough it could. Number 3 had a stubby, fat cock with almost no head andnumber 4's slim, curved memberwas difficult to bend back into my mouth, but when he came, the secondload of the night into my mouth,it was huge and burst from my cheeks."Thanks for the show guys," said Paula, "next week's meeting will be orlast and it should be fairlyspecial."We were like sheep, accepting our instructions for the next meeting. Wewere given cock rings and toldto learn how they worked on our own, but to make sure we had them onnext week, before the meeting.Monday, session 8We were very surprised to see 8 more women seated in rows facing ourarea. They were all dressed to killin short dresses, heels, and sexy blouses. None of them were gorgeous,but all of them looked prettydamned good."This is our class, gentlemen and we wanted to share our findings withthem."Paula spoke first and what she said floored me. "The experiment was toshow how weak men were and howthey could be turned into masturbators and cocksuckers by controllingthe libido.""Strip, gentlemen. And give us a good show."As we stripped, we all noticed each other's shaved cock and cock rings.We stood nude in front of thewomen and they began to write in small notebooks. We found out laterthat they were betting on who wouldcome first, last and most."Lets see them jerk off." Said one of the women.We started by grabbing our own cocks and stroking up and down untilPaula walked over to us and startedto pair us up."Watch this ladies, they'll even jerk each other off." I had number 3'sarching cock in my right handand he stood next to me with his left hand curled tightly around mystraining boner.Some of the women got out of their chairs to stand closer and get abetter view. They were so hotlooking in their heels and hose that I almost came."Stop it now, stroke-boys," Cindy shouted, "you're gonna wear themlittle peckers out if we let you...and we want to see some action.""Number 3 will suck off Number 1, and Number 2 will suck number 4...now."Number 3 kneeled in front of me and started sucking and stroking asnumber 2 pushed number 4 onto hisback and started to blow him with a vengeance." The first one of you to make the cock in your mouth come will get aspecial treat... and the owner ofthat cock will not get one... and no hands, just suck-boy mouths." Paulawas talking to one of the womenstanding next to me and they were betting that I would be the first tocum..."Look at him, he's sweating already."Number 3 and I tumbled onto the carpet and he quickly gobbled my rod asI lay on my back trying to lookup the dresses of the women around me and straining not to cum."I think he likes my legs, the way he can't keep his eyes off of them."The woman was about 30, shortand slightly overweight, but she had such gorgeous, muscular legs andwas wearing a short, tailoredskirt with high heels and no pantyhose. The little gold ankle braceletwas driving me wild. She gotcloser to me and squatted down right by my head. I could smell herfreshness."Do you like my legs?" she asked as I nodded. My balls were tighteningup and I was getting so close. Iwanted to look away so I wouldn't come, but she was teasing me andtelling me not to shoot. "You wantthat special treat don't you?" she cooed. "Does his mouth feel as goodas your hand?" She was laughingand her friends started chanting around the other guys. "Cum, cum,cum...,"I was right on the verge when the shouting told me that number 4 lost."Stop it now, number 3," shouted Cindy. My cocked popped out of hismouth just in time. I had to closemy eyes and struggle to prevent the cum, but somehow I did.Thank you number 4. You may go." He was dismissed. As Cindy led him tothe other room to get dressed, helooked around the room with a dazed expression."Sit here and wait, number 2," Cindy was making notes and whisperingwith Paula."OK, ladies, what would you like to see now.""Make number 3 jerk for us," said a dark haired woman around 50. Theothers agreed and number 3 was leadto the center of the group. They got up close to him as he beganstroking."You will stroke for 8 minutes and will not cum." Cindy said.His cock was huge and straining as he gripped his cock and strokedfuriously. Paula dripped some lube onit and he almost buckled. "This lube gets hot as he strokes it," sheannounced matter-of-factly. "He'llnever make it, will you stroke-boy?" The women started to count theminutes and when they got to 7minutes they started to whoop and holler and chant 'Cum, cum, cum..."He almost made it, but his knees collapsed and he moaned loudly as hiscum shot out from his cock andlanded on the shoes and ankle of the woman who had taunted me. Shejumped back laughing as Paulaannounced that number 3 was excused.Cindy brought a towel to the woman with the cum on her legs and shestarted to wipe it off when shelooked at me and smiled."Maybe he would like to do it for me," she smiled and started to walkover to me. She started to hand methe towel and then pulled it away. "You wont need this will you?" Theother women were starting togather around as she stood there. I got down and started to lick the cumoff of her beautiful legs andankles."Get the shoes, cum-licker." It was Paula's voice. There were snickersand comments all around me. WhenI was finished, I sat back on my haunches and my cock fairly danced frommy lap."Hi boys," the voice was Darla and she stood in the group wearing ashort leather skirt, very high redheels and no shirt. Her perky tits were standing high and she walked tothe middle of the room as Cindywheeled the Gurney over.Paula introduced Darla and explained that on previous times she couldn'teven get to suck our dicks aswe were too busy cumming in our hands or each other's mouths. "Tonightwill be different. Darla willmasturbate these two until one of them cums. He will be the loser. Thewinner will get Darla's mouth forhis enjoyment." Paula then chuckled and looked at Cindy who grinnedbroadly.We were helped on to the gurney with our heads at either end. Our cockswere next to each other andballs were mashed tightly as Darla stood behind the gurney and graspedour cocks together as she startedto stroke up and down. No finesse. Just up and down with a steady mediumrhythm. The women gatheredaround tightly and started to giggle and make comments as to who wouldwin. Our heads were hanging offthe gurney so we couldn't see Darla's hands unless we stretched ournecks hard, holding our heads up. Itwas too exhausting and our heads fell back off the gurney facing back.The woman who had been teasing meall night was right there. She started to raise her skirt very slowlyand then when it reached hercrotch I could see the thin patch of underwear. She moved toward meuntil my face was an inch from herpussy. I could smell her juices and was lost in the moment when Istarted cum and the women started tocheer.The woman looked down at me with a mocked sad face and then whispered"buh-bye..."I was taken to the other room and as I dressed I could hear the whoopsand hollers from the women asDarla got busy with the last guy. I later learned that the women hadmade him stay hard for an hour moreand then he came in Darla's mouth mere moments after she wrapped herlips around him.I went home and jerked off for hours.I just got my check from the school yesterday. I haven't seen any of theguys from the experiment, butPaula has made me jerk of for her sister and give her husband a blowjobwhile she and her sisterwatched.She told me Cindy is dating number 2, Harry, and wants us to give them ashow at the next 'Girls NightOut". I am looking forward to it.
