I remember it like it was yesterday.
15 years ago my wife was with another man for the first time and he tried to push her head down toward his huge cock and she said I don't really do that. He said what do you mean and she said she only gives me oral on valentine's day, our anniversary and my birthday. He said I'm not your husband and you're not my wife, you're my slut and from now on you suck my cock and he pushed her head down firmer and she sucked his cock.
After a few minutes of deep throating his cock he said do you have anything else you won't do? She said I've never done anal and that a definate never going to happen.
He refused to put on a condom and when I tried to interject he back handed me, he caught me off guard and it knocked me to the floor. He buried half his cock into her raw and she moaned oh gawd and he said do you want me to pull out and go home or keep going? My wife moaned fuck me, and he said fuck you how? And my wife said fuck me raw.
An hour and 20 minutes, after already cumming in her pussy one she was having her I don't know 100th orgasm on his cock when he pulled out and pushed about a third of his cock into her ass taking her anal virginity.
As he had her dress him before leaving he told her she wasn't allowed to suck me ever again, that if she wanted sex with me I had to wear a condom, and that he owned her ass and she wasn't to ever let anyone fuck her ass, he'd be the only man ever to know that pleasure... and she agreed.
