I have a decent girth , 6.5" continuous full shaft. Most women I have screwed had a "ring" to get through. And with my girth it is not uncommon to have to "work" it in especially on a new girl that has not had girth yet. And once you "Pop" in, it is smooth sailing till you find bottom wherever that may be on the individual girl. My wife has a very tight ring, and when I get a couple fingers in her I can feel around to the walls inside, A bit of a cavern UNTIL she comes, then everything is inflamed and feels like a Nerf football inside, LOL!
But I did have one tiny spinner girl, 4'10" 88LBS gymnast. She was 18 and a day when I was fucking her. I measured her and she measured me. She was 31" hips and 21" waist. Real narrow but a bubble butt of she would not ave even been 31" and really small waist I could almost touch my thumb and fingers around. Pussy had this tiny slit maybe 2" long at most and very petite vulva. Pussy was super tight to the point could not get in her even with lube the first couple attempts. I have to give the assist to a big fat joint and some Peach Schnapps one night. Mellowed her out, made her REALLY horny and relaxed best she could. What was amazing with her though is getting past the ring was a lot of work, a good few minutes of constant pressure and lots of lube, but once past the ring, she was super tight inside all the way and I swear she was tighter the deeper I got in her. We joked about me getting the new pussy (I her biggest in all dimensions), But I have told people for 25 years since it was like fucking a funnel!
She was incredibly uncomfortable the first time for what was probably a realistic 15 minutes of stroking SLOWLY.
Her pussy just would NOT loosen up. She squirmed, grunted and complained and put the Heisman on me so much the first time I thought I would never get a chance to fuck her again. But I was back on it a couple days later. We were booty calls for one another for a couple years and she got used to / hooked on my size after a little while. But for a couple years and a couple hundred fucks, I pounded the shit out of her, that pussy never loosened a bit. It felt like I was killing her and my cock would be sore. I was fucking a couple other girls also at the time (the spinner had a boyfriend, wealthy family she was marrying into, terrible fuck according to her). And I had the chance to fuck her and fuck another girlfriend a few hours later, and that girlfriend was nice and tight also, but no pussy was like the spinner! And never in 50 or so conquest under my belt, did I ever have another girl that got tighter the deep I went.
The spinner must be 43 to 45 Y/O now. Damn i would like to see her / fuck her and see if it is the same pussy.
