Late one night your ex-girlfriend is having an argument with her boyfriend who is in jail. She doesn't know when she'll be able to see him again and she's upset because she didn't sign up for being in a relationship with someone who won't be around for a few years. She feels so lonely with no one and it makes her reflect on her relationship with you. She knows she didn't appreciate you enough when you dated years prior. As she looks at your picture with your wife, she longs to have you back. She knows your wife doesn't appreciate you they way she could now. That's when she makes the decision to use this experimental app to swap bodies with your wife. The device works and while your wife is folding laundry her phone rings. When she picks it up the body swap takes place and your ex-girlfriend takes over her body. She falls to the floor twitching while her body is being taken over. Once the body swap is complete, your ex is now in control of your wife's body and comes to find you and fuck you. You don't notice anything at first. It just seems like your wife is trying to be flirty and spontaneous. But something about the way she talks doesn't add up. Still, you don't think on it too long before she starts sucking your cock with a certain enthusiasm you've only seen with your ex-girlfriend. It's nice. It's better than nice, your wife is the sexual vixen you've always wanted her to be. She then stands over you and sits on your cock and starts riding you. You're loving every stroke when suddenly she goes limp for a second or two. Then she sits back up pretending that nothing happened. 'That's strange,' you think you yourself, but continue to fuck her in different positions. She does the same thing a few more times. Almost as though she's in a trance and briefly snapping out of it. But you've never seen her this way before and the sex is amazing. You fill her with a huge load when she stands up and confesses that she's not really your wife and now that she's taken over your wife's body, she wants to hit the town and fuck as many men as she can. You have no idea what to do.
