Girlfriend Cuckolds Boyfriend

*custom request you're my girlfriend and you're sitting on the couch with legs crossed teasing your shoes/feet and you're telling me about this really cocky guy at your work who keeps telling you he'd be the best fuck you've ever had, etc. you're laughing because you know there is no way he can be as good as he says and you're tempted to embarrass him and deflate his ego. you then realize a "great" idea would be to make a bet with him. you'd fuck him and if you make him cum first he has to pay for a trip for us to go on and admit to everyone at work just how great you are and how terrible he is. you're really cocky about it (teasing your feet) because you know he can't handle you and we have been wanting to go on a road trip. you notice i'm not really fond of the idea so you start to pump me up... you admit that "yes, you will technically be 'cuckolded', but it will only be a one time thing" and that "there is no way he's better than you", "this is a sucker bet... i'll totally drain him" etc. you notice my dick getting hard at your legs so you tell me to jerk off to the pace of your foot moving and if i cum, you get your bet and i should even watch. i ofc cum on your foot and you say you're excited to set the bet up. next scene (doggy, perpendicular to camera. 'penis' offscreen) you tell me you're about to start the bet and that 'when' you win by making him cum, he's going to have to pay for our vacation. you reveal that if you lose, he gets to take you on that vacation. you assure me that he's got no chance and you are laughing about what a sucker bet it is... until you feel him "enter" you from behind. your face is surprised about the size and how it feels but you collect yourself and say things like "don't worry babe, we got this etc". but then you start getting fucked harder and start to say things like "he's huge and this feels really good." you keep fucking and you say "ok, enough fun and games... i'm gonna make him bust". and you are reverse thrusting and saying back at him mockingly "yeah, am i gonna make you cum? are you gonna lose this bet?" but your face betrays that winning will be far from easy. at which point, i snap and stand up to reveal i am erect and masturbating. you are shocked, but not compared to when i then tell you to start playing with your clit. you clarify "you want me to lose?" and remind me that means going on vacation with this other man. i affirm that and hornilly say i want to hear you cum on his cock. you lose control and say "sorry honey but he's going to own this pussy" as you cum hard on his dick. i offer you guys privacy for round 2. final scene (solo pov) you come out in a (bathrobe, etc). and sit down relaxed. you tease your feet and tell me you had no idea that someone could be so good in bed and that you had the best sex ever, making my dick twtch violently. you laugh out loud, saying you cant believe i greenlit being cuckolded. i smirk and say i want to be again. you fantasize about your future sex-cation
