my current wife is the only woman that I have had anal with, that would come like gangbusters, just from a good rear end screwing.
When I took my wife's anal virginity, she said the feel of my cock sliding into her ass made her cum instantly and it was super intense..... And years later when she pegged me the first time, I didn't cum hands free but I stroked as she pounded my ass....my orgasm was the most intense one I've ever had......
Mmmmm she fucked my ass doggy style, she had me reach back and spread my cheeks as she fingered and lubed my hole, then she put the tip of her girlcock on my virgin hole and began to push in, stretching my hot, tight hole until she slid it all the way in, popping my cherry ass..... Mmmmmmm so hot, precum was running out of my cock in a stream....
At one point, my wife was the same way, wanting anal sex instead of vaginal, made her cum fast and HARD, I was fucking her ass several times a week, not counting weekends which were basically anal orgies. We went through A LOT of lube that summer !!!
Nowadays, I have a difficult time having an orgasm without something fucking my ass, whether it's a dildo or another man's cock. Blowjobs require a longer time sucking without something working my ass.
