“I don’t really do vaginal sex,” he said on their first date. At first she was confused and thought maybe he only wanted blowjobs, but he clarified and said that he was anal only, and did anal sex and oral, but nothing that involved the vagina. She hadn’t heard of anything like it, and hadn’t tried anal before, but she’d always wanted to, so she figured he would be a good person to try it with if anal was all he did, because he must have a lot of experience.
Before long, he had her ass well trained and eagerly anticipating the next time it would be filled by his cock, and she found herself perfectly happy with the arrangement. Maybe she’d start calling herself “anal only” too!
