What Other Couples Cannot Do

Standing before me were Jason and Liz. We used to hang out together all the time before my wife ran off with an idiot. But that's another story. I met up with them in the park while walking our dogs recently, and they told me a most remarkable story. He is normal enough: White, 6'1" tall, not overweight, short hair, friendly smile. She, on the other hand, is rather unusual. She is quite short, like maybe 4'8" and very thin. One might think she is anorexic, but they insist she's not - just naturally thin. She comes from Thailand, with very dark skin, almond eyes, and long hair that's not curly, but with a wave. She likes to wear bikini tops over her small boobs, which only enhances her sexiness. They tell me they don't care for ordinary sex. She says her vagina is a bit small for his somewhat oversize penis, and so when he pushes too hard, as he inevitably does as the passion heats up, it hits the back of her passage, and makes her feel sick to her stomach. But they tell me they are a very sexual couple. They do everything else. Especially one thing that only they seem able to do: Liz can slowly work her little finger into Jason's urethra. They say it is like her fucking him. I asked for details, because this intrigued me. It started with playing one night when she just wondered if it would fit. She started putting her finger in his peehole, but it hurt, and he made her stop. She didn't even get halfway to the first knuckle. But, a day later, Jason said he liked the idea. So she carefully trimmed her fingernail, and a couple of days later, they tried again. They experimented with olive oil, coconut oil, sex lube, spit, and finally used her own built in lotion from her vagina. That turns out to be the most slippery - at least according to them. To be sterile, she first dipped her hand in rubbing alcohol and dried it off with a paper towel. Ever so slowly, she worked her little finger into Jason's urethra until it was nearly at the first knuckle. He said it stung, but he liked it. After a brief pause, he insisted that she keep pushing, and maybe rotate a bit. Suddenly, the knuckle slipped in. The sudden way it slipped in, scared them both, and she immediately pulled it out. That hurt! Jason said it didn't hurt all that much going in, but when she yanked her finger out, that got him! But only for a moment. They grabbed a flashlight and carefully examined his peehole. The outer surface was starting to swell up, but so far as they could tell, nothing was torn or injured. That was enough for that evening. The swelling was gone in the morning. But Jason said that peeing the next couple of days was painful - a stinging sensation. Liz piped in that it must have indeed stung, because you could hear him yelling across the house from the bathroom. Now, you would think that would stop any man from wanting to do it again, but you'd be mistaken. Jason wanted more, and Liz said it was "Cool!" meaning she enjoyed putting her finger in Jason. So, they practiced every few days. After a few weeks, she could get two knuckles in, and it no longer stung. I was surprised to hear that, but it is evidently like building callouses, or olfactory adaptation - the body adjusts nicely. As time passed, she was easily able to push her little finger all the way in. Jason's peehole must have expanded in some way, but nothing is visibly different. He offered to show me the end of his penis at that point. Pulling down his shorts, I took a close look. I gently grasped his penis, spread his peehole open, and yup, everything looked normal. As I was doing that, I noticed he started to harden up a bit. But we didn't pursue what might have happened there. He pulled his shorts up, and continued the explanation. Evidently, there is a greater restriction about a half-inch inside the urethra. When something just small enough is pushed in that it will get past the opening, it sticks at that inner point, and must be carefully inserted so that inner restriction stretches. And that's the part that needs the most work. Now, Liz has been trying to push her skinny little index finger in. She says that for her, it is a better sensation. That she really enjoys the tight yet slippery feel of the inside of Jason's urethra, but can't feel it nearly as well with her little finger as with her index finger. Jason has to be fully erect for this to work. Her finger, even her little finger, just won't go into a soft dick. She says it is too floppy, and she can't get a good supportive grip on it with her other hand. I can understand that. It is sort like the inverse of sex. Try fucking with a soft dick. Pretty hard to do, eh? So there he is hard. Does he ever cum while she is doing this? I mean, what would happen if he ejaculated while the opening is blocked? Yes, it has happened numerous times. They tell me that the first time it happened, it scared them. And it hurt a bit. Perhaps you (if you're a man) have tried peeing while holding the tip of your penis closed. If so, you know, it hurts as the inside of the most distal portion of the urethra is stretched. And Jason tells me it is somewhat the same. However, he has adapted to that also. It no longer hurts. He says he has his best orgasms this way, with Liz's finger blocking his ejaculation. Lately, they've been experimenting with leaving her finger in there after the orgasm is over. He says after a few minutes, as his dick goes limp, the inside starts to itch, and he feels a need to let that cum out. Jason wanted me to know that the orgasm lasts longer and is more intense if the cum can't come out. The story takes us to the present moment. They are continuing their experimentation. They say they want to try to keep her finger in his penis longer after ejaculation. Maybe even fall asleep that way. There is one other concern, however. Her finger is quite compressed. Might this disturb the blood supply to her finger if left in there too long? They also want to try what they're calling 'forced retrograde ejaculation.' She'll give him an orgasm while his urethra is blocked. After the contractions subside, her plan is to press along the underside of his penis back toward the base, squeezing the sperm back in. It won't go into his prostate, but rather through the sphincter and into his bladder. So far, they have been afraid to try this. The concern with that is that she might be introducing bacteria into his urethra. To send the sperm, potentially carrying that bacteria into his bladder might not be a great idea. I had to ask the obvious question. Can you guess what I asked? Here it is: Have they ever tried putting a finger into Lis'z urethra? Yes, they have! It turns out that the female urethra is more stretchy than the male, and of course it is much shorter. So, she was able to accommodate Jason's little finger without too much fanfare. He says it is a delightful feeling. He can push it all the way past her sphincter, and into her bladder. He feels the constriction disappear as the end of his finger makes it past the sphincter, so there is no doubt he is in there. I forgot to ask how often they 'do' Liz. I'd really like to know. This whole concept really excites me, and I'm all set to watch them do it. The only problem is, I do believe they'll want me to participate. I love hearing about fingers in urethra's but I'm not sure I want one in mine, at least not just yet. I wonder if they're willing to be sufficiently slow and gentle? I also wonder if I could put my finger in Liz's urethra. I'd love that! I have masturbated a half-dozen times thinking about it.
