Mackenzie looked up into the eyes of her mother’s boyfriend and wondered if he’d be cumming soon. She’d just turned 18 that week and she knew it would be rude to deny him the use of her body while he waited for her mother to get home, but she wanted to go out and have fun with her own boyfriend.

“You’re a better cock sucker than your mom! I’m going to have to show up early more often,” he said, then winked down at her.

She moaned something like a “yes” around his cock, even though she’d rather he didn’t, but she didn’t want to be rude.

“I might just have to try out that fresh little ass and cunt before I take your mom out tonight. Maybe I’ll just tell her we’re having a night in and I’ll fuck the hell out of you while we watch a movie.”

“Great, there go my plans for the night,” she thought, but moaned enthusiastically around his thick cock, like a polite teen should.
