Vibration Persuasion

I had 3-4 hours of free time and since I had a key to Siobahn's house, I though I'd make a surprise visit. I let myself in and made my way through the kitchen. It was very quiet and I wondered if she was home. As I approached the sitting room, I noticed her stretched out on the couch asleep. It was hot, and humid out and she was dressed only in a button down shirt and panties. Obviously she wasn't expecting company, but I was transfixed by what I was looking at. She was on her back, the shirt was unbuttoned about half way, exposing some of her breasts and her tanned and toned legs were stretched out along the couch. I carefully walked over, sat on the edge of the cushion and kissed her gently on the forehead. As she began to stir, her eyes opened. "Ohh, it's so good to see you, I like waking up this way. Can you stay a while? She asked. "Yes, I have a few hours. I have something to ask of you." "Go ahead, ask away." She replied eagerly. "Can you follow instructions and adhere to rules implicitly?" I asked. "For you, that is never a problem. I trust you and your judgement. I know you would never put me in an uncomfortable situation." She assured me.  "Good," I said. With that I told her to stretch out on the couch. As she she did so, I slowly pulled her panties off, left her shirt on but exposed her breasts. She looked extremely seductive. I could feel my erection start to form, but this was going to be about her first. I removed the wand vibrator from behind the chair and placed it next to me. "I am going to give you one explicit instruction and you have to comply fully.  "What are you planning?" "You are not going to be allowed to cum until I give you permission. No matter how close you think you are I will tell you when. Understand? " "Yes." she agreed. I held the vibrator in my hand, turned it on, and began rubbing it lightly just below her navel, guiding it down toward her vagina. She jumped a bit at first as I approached her vital area. When It brushed against her clit the first time she groaned a bit so I decided to leave it right there.  "Ughhhhhhhhhhhhhhhhhhh, oh oh oh oh, ughhhhhhhhhhhhhhh." she moaned, Not loudly, but more from her throat. Her nipples stood tall as she began to writhe a bit. After about 2 minutes of this she started to meekly plead, "Please??? Let me cum.... I need it." It wasn't in earnest, and she wasn't really at the stage I wanted her at yet. "You're not even close," I said. "Oh it's so good, I'm ready!"  I took the vibrator away and let her mellow a bit, but not for too long. As I replaced it she began to move around a bit, kind of flailing her arms. I was surprised she wasn't pinching her nipples. I guess she was so focused on not cumming that she just ignored them. "Oh god it's too hard, too hard," she protested, so I cut back on the pressure against her clit. "Ohhhhhhh, please, I can't fight it , I'm so close." "You have to fight it," I said softly. I continued to rub her in a soft, circular motion as soft unintellible whimpers started to come from her. "I'm soooooo close, I can't help it, I need it now, ohhhhh god," she pleaded. She was a sight to behold. Breasts exposed, nipples taut, face in a comination of frustration and ecstacy. I knew I had a hard on that wanted to bust through my shorts, but I was'nt concerned with that now. It was impressive how she was using all of her self control and fortitude, to comply. Ughhhhh,umphhhhhhhh, ohhhhhhhhh, " she groaned as she started lurching toward the vibrator. I increased the pressure. "Wait, wait, wait," she begged, and I pulled it away for an instant. She breathed deeply, "Oh godddddd," was her respnse as I placed it back on her swollen clit. "Oh god, all I want to do is cum, can I cum??? Please???? She was now rising up off the couch begging me. "Ummmmmmph, uh uh uh uh uhggggggggg, god oh please can I come now????" "Go ahead, cum for me!!" " OH, OH, OH, Ahhhhhhhhhhhh, Ahhhhhhhhhhh Ahhhhhhhhhhhh oohhhhhhhhhhhhhhh!!" she responded in long guttural tones as I kept rocking the vibrator back and forth over her clit, until finally she grabbed my hand and begged me to stop. "Please. I can't breathe!!"  I stopped and held her hands as she came down from an intense orgasm. "Phew, That was something else, I've never had to use that much self control for anything. There was a moment when I didn't think I would make it. You made the call just in time. I don't think I'd do that too often, but I'm glad you gave me this experience." I was holding her to me and stroking her hair. She looked totally exhausted, but peaceful. Then she took me by surprise as she began stroking my semi hard penis to attention. I started to say something but she put a finger to my lips. "Shhhh," she whispered. Siobahn slid down and with her lips pursed and tongue sticking out just a bit, she began licking up and down my hard on. After what I had seen, plus how I was being administered to, it took no time at all before I was shooting streams of cum all over my chest.  We both sat on the couch in each other's arms for a while before we cleaned up and bid each other good bye, but not before she turned to me and winked. "I owe you big time."
