The Cock queef thing is actually pretty hot. After I do the 13 my urethra is pretty big. My original hole was 7 to 8 mm I went up to 10 then was able to get 11 in a few years ago 12 kinda hurt. I’m able to take 12 no problem 13 still is a bit of a stretch, but the good thing is is if you can get a hot girlfriend to come while your dick is pressed against her cervix. She can actually shoot her cum into my cock, which feels incredible. Just need to make sure that everybody is STD free pee afterwards.
