She propped herself up in a modified doggy position with one leg up on the bench seat and one on the floorboard while I shoved it into her ass. It fel... so damn good. Tighter than her pussy, but not as lubricated; it felt great, naughty, and based on the amount of friction and the grip her asshole had on my cock, it wouldn’t take much to explode in that ass. She enjoyed the experience as well, and when I was about to blow my load, I asked where she wanted me to cum. It wasn’t a common question. When he arrived he set his suitcase down and took her directly to his bedroom. GF smiled and winked at me as she passed by.A while later they both came out in robes to the dinner I had prepared, then back to the bedroom. A tired redhead came for coffee in the morning and said she needed sleep. He’d been horny as hell. I could have her after she rested though.When I slipped into her pussy she said, “Just take care of yourself. I’ve had plenty.” It didn’t take long for me to add my contribution. “I want a car,” she said.“You’re only 15,” he said. “You don’t even have your permit yet.”“I’m only 15 for five more months,” she said. “And if we start thinking about it now I can have it on the morning of my sweet 16.”“What kind of car do you want?” he said laughing.“A black Mercedes,” she said.“There’s no way we’re getting you a Mercedes,” he said laughing.“But daddy you bought Jacob and Jenny cars,” she said.“We bought them used cars after they graduated high school,” he said.“Please. "Yes, definitely," she answered, sure her mother caught both meanings."Should I take that as a yes, then? That this is what we should get you for your birthday?" Yeah, sounds super. You look terrific in yours, too. Are we getting them both?" That's the idea. And I want us both to wear them for the big party. I did tell you it's going to be a double party didn't I? With Uncle Mark's number forty coming up and your number nineteen almost the same time, we thought we'd just combine them." You want.
