It's the ass that seems to attract the guy the most. Once he's tried it, he won't want to deny himself anal pleasure anymore. A girl has a chance to offer him MJM to fill both holes. And if you offer it to a guy during sex, he'll agree to anything. I'd love to hold on to those little tits and cum on them.
My son went to his mother's house to work. She decided to give him a hot sex lesson. As a result, he fucked his mother right in the workplace and poured her a mouthful of sperm.
The mother let her son do whatever he wanted, thus making his deepest desire come true, let him fuck himself in the ass.
