Erica cums and claims you permanently

It doesn't take long for your thrusting and your continuous stream of cum to send Erica over the edge. She drives her hips downward and cums forcefully around your new cock. You feel her pussy twitch as you continue to cum, moaning in pleasure. She taps at the phone and you feel your dick stop cumming before she lies on your chest. You continue to tremble from the sensation, sweaty and sore. You and Erica both breath heavily for a moment.

Erica stirs, and you feel your cock slide out of her as she slides her hips up your torso. "Good boy," she rasps. "As a reward you get to suck your own cum out of your mistress's pussy." You look up to see her looming above you. Thoroughly defeated, you open your mouth, tongue out, and she presses her crotch against your lips. You start idly licking and sucking, and Erica moans softly. You get a warm sensation as you lap your cum out of her pussy, enjoying the taste mixed with her pussy juice. Your lengthy orgasm unleashed a huge volume of cum, and no matter how much you lick it out and swallow, it starts to run down your cheeks as she grinds against your face. "Don't worry," she says. "I didn't give you the ability to get anyone pregnant." You hadn't even considered the possibility, and close your eyes as you swallow another mouthful of cum.

Both of you rest there for a moment, Erica softly grinding and you cleaning her out with your mouth and tongue. You register a beep from her phone and feel your cock twitch. Looking up, Erica is showing you her phone screen again, which now displays the message 'Implant securely paired to this device.'

She reaches back to give your balls a squeeze before slowly standing up, and walking to the bathroom. You hear the shower turn on and start to realize what you've done. You have a cock, and your roommate owns it. Permanently.
