Go slowly

You go slowly because as much as Isabella might be a bitch, she's turning out to be your bitch and you still want her in working condition later on. If you plan on fucking her ass again in the future, you might at well take care of it a little now.

You you slide your well-lubed in cock very slowly. Pausing to allow Isabella to get used to it once you've got your fat head in.

Soon you have a good rhythm going and you're fucking Isabella ass good - you can barely believe it - you're actually fucking Isabella's ass. It's been such a long night you aren't even sure how much she's still tripping and how much she's just actually a slut.

You prompt Emma to take some photos and videos of you fucking her friend in the ass - including some hot video of Isabella moaning on and on about how much she loves it.
