You did make an agreement with Matt... might as well do it.

Your desperation to be the first to get into her hot virgin pussy overpowers your ethical standards, and you put down the video game controller. Gently, you slide your thigh out from under Kara's head and join Matt on the other side of the couch. Thankfully, Matt doesn't argue about the order of the fucking (probably because he needs time to get it up again anyway), and he stands next you. You get on your knees, hook her legs over your shoulders, and position your once-again-throbbing cock at her slick entrance.

While you basically stayed away from Matt while he was getting his blowjob, Matt looks intent to be an audience. You give him a look, hoping he'll get the hint that you're annoyed, but he just shrugs and says, "This is better than porn."

You're not gonna let Matt's voyeurism get in the way of thrusting into the sweet, sticky sex pressed up against your fat dickhead, so you turn back and try to focus only on Kara's face. Her lips are slightly parted and have a bit of dried cum in their corners, and her cheeks are completely flushed. If her eyes were open and starry like they usually were, you wouldn't be waiting, but there's something a little creepy about this. You don't see the world through me-only goggles like Matt; you want to feel that you're pleasuring the girl, too.

"What are you waiting for?" asks Matt.
