Uterus Fucking?

So my wife met this new guy via Craigslist. She put out an ad and he responded. After a few text messages back and forth they arranged a time and he showed up at the house on Saturday evening. When he showed up I was surprised. He isn't her normal "type". She usually goes for the masculine, big, burly, manly guys with hairy chest, tattoos, a fat cock and a dominant power-fucking attitude. This guy was the anti of that. He was maybe 5'4", about 130 pounds, non-muscular body type (what I would call "skinny geek"), a very meek and quiet permisterality and generally a quiet, non-masculine guy.

As usual my wife greeted him pretty much naked in a pair of sheer panties, a sheer nightie and "fuck me" heels. In essence, nothing was left to the imagination. After a greeting kiss she led him to the bedroom. After some kissing and fondling she dropped to her knees and undid his pants and I was shocked to see a pole spring out. My first guess was that he was 9-10 inches long, she later sid that in his text message he claimed 10.5". On the flip side, he fell short in the thickness department and was no more than 4" in circumference. Again, not what she usually likes as she usually goes for the wrist thick guys with no concern for length.

After some major deepthroating she laid back on the bed and he fucked her. In the midst of them fucking I heard him ask her if her uterus was available to which she shrugged and told him to fuck whatever he wanted. A few moments later and she was cooing with pleasure as he buried his cock to the balls in her. It was at this point that I knew he was in her uterus because she can't take anything over 8 inches to the balls without them bottoming out. She has a dildo that is 8 inches and just before taking it all she says that it hits bottom. So the only way he had 10.5 inches in her was if he was in her uterus. After about 20 minutes of him fucking her slow and deep he let out some low moans and came in her uterus.

He quickly and quietly dressed and left with hardly a word said. Of course this is where I normally come in and I went down on her expecting a cream pie...not a drop. After several minutes of eating her I told her this and we came to the conclusion that after he pulled out her cervix must have closed back up and kept all of his cum inside. I know he came because I saw some of it drip on the bed from his cock when he pulled out.

So this is all new to me and her. I did some math. I can touch her cervix with the very tip of my middle finger so her cervical opening is about 4 inches into her pussy meaning he was about 6 inches into her uterus. Is that possible? Also, wouldn't him cumming in her uterus make it more likely she will get pregnant? She has had her tubes clamped but we have read that the success rate is only about 75-90% with clamps so by him cumming right into her uterus and her cervix closing up and keeping it in it seems that the odds of pregnancy would skyrocket, right?

I love to be humilated over my little 3 inch dick.
I watch you bareback her then I clean up.

man thats fucking hot!

Added bonus. He is on his way back over tonight. She is all turned on by the idea of him fucking her uterus now. She texted me on her way home from work and said that he was coming over. He is supposed to be here any minute. Finding myself quite aroused at this too. As much as I love to slurp up a sloppy creampie, the idea of being deprived of a creampie because he came so deep in her uterus that it stays there is pretty erotic too.

I suspect that, to a sperm cell, the opening in your wife's cervix looks pretty big even if she has not been pierced by her lovers remarkably long Cock. I guess his load of cum got a "head start" so-to-speak, but the main thing is still the effectiveness of the clamping procedure.

Anyway, I hope you don't mind missing out on your cream pie. It sounds like your wife likes the feel of her boyfriends Cock in her uterus! You better get used to it... I wonder if the horns on your head will grow longer each time!
Old Enough to know better...but I don't!

I don't know if its realistically possible for a cock to penetrate the uterus through the cervix. I think the opening will allow semen, but not cock.

Recently a dominant black Bull fucked my wife aggressively, hammering against her cervix, and pressing his cock with more and more pressure against her inside wall, till she could barely handle it. He was about 7.5 inches. I don't think a cock can penetrate there, but my wife experienced what happens when a man big enough tries - 3 days later she still aches.
