You tell Isabella to hold Sophia's wrists.

"I'm going to roll Sophia over and you grab her by the wrists and hold her down."

Isabella thought you were going to seduce Sophia, but she's realizing that this is more like ****. And she's helping you do it. She's helping you **** her friend... What has happened to her, she wonders. You've broken her in entirely. She looks down at your hard cock that is glistening with her spit and grabs Sophia by the wrists.

"That's good," you tell Isabella and then you roll Sophia over so she's on her back instead of her side.

Almost immediately Sophia starts to rouse, but she's disoriented having been awoken in a not normal place and in an abnormal way. It takes her a moment to register Isabella standing naked with her tits hanging down above her and to feel that Isabella is holding her down by her wrists. And by the time she registered you, and that you're also naked, oh and yes - so is she, you already have her legs spread apart.

You only pause for a moment to take in that little miss prude has a completely bare pussy. Perhaps that's how Zach like's it, or maybe she's always been a secret slut.
