I watch porn scene with guys to long to go balls deep and think I would rather be able to go balls deep then have a couple / few inches I could not get wet. At 6.5"L X 6.5G I was able to get all the way, or damn close to all the way with all but a 2 girls. One a 4'10" 85LB gymnast. Tiny everything. Never got the last 1" / 1 1/2" in but only fucked her maybe a dozen times. Her little pussy was so small, her entire slit end to end was maybe 1 1/2", shorter then the over 2" width of my cock. There was slight tearing / bleeding every time, I thought she was a virgin with the bloody mess the first time, I was really way to thick for her, but she was hell bent on being able to handle me. This was the late 70s, I called her Timex pussy, take a dicking and keep on ticking. Hurt her but she took it but never balls deep!
What would become my wife was so crazy tight and shallow, the challenge was great but it would get so frustrating as she really could only take 4.5" to 5" tops. I could rub the opening to her cervix with my index finger if I got her legs behind her shoulders and dug in deep. I remember clearly the night after my best friends wedding (God dam women get horny at weddings), 6 months into our relationship and talking about getting married. I would joke with her and tell her I could not marry her, her pussy was to small to take all of me and we had to fix that. She said she could take it, I told her tonight she was going to. I had worked the opening to her posterior fornix but no entry!. This night she got in doggy, me standing beside the bed, big back arch, ass pushed back, face in the pillow and relaxed. I POPPED past her cervix into her posterior fornix. because of my 6.5 girth, and helmet head, it was beyond tight and first time in the PF uncomfortable enough for her to pull away and go fetal position. It was a very playful "dare" of sorts, We got back to it and I was getting in the PF and she would pull away / grunt, then arch her back and set up for more. Once I got in there, and did not pull back far enough to pull out of it, I was able to fuck her balls deep that last 1 1/2" lodged in her PF. And the tightness on that last 1 1/2" was indescribable. She always would have vaginal orgasms, but this time she had a long vaginal orgasm , 30 seconds I would say, that was extremely physical and VERY emotional! After a couple minutes I cum and when I pulled out my head / helmet was red as fire! As we lay collapsed in one another arms, I said, well that's it, guess we can get married, LOL! In the early days I could not fuck her that deep every time, that was reserved for a let's go out for some cocktails, smoke some weed and fuck your brains out! Liquor always made / makes her looser. She would be REALLY sore next day (s), but LOVED it when the mood was right. Fast forward some years, and we stretched that opening, she got accustom to it and i fucked her balls deep every time. She is stil at 55 Y/O incredibly tight, but we have reorganized her pussy, LOL! And I have since fucked her 8.5" deep using even thicker extensions, dildoes, etc. but that 8.5"L gets us to the back wall of her PF and that is max depth.
