You're not sure yet

Once parked you get out of your car and keep an eye out. Other than other students parking and getting out of their cars, the girls stopping only to undress completely, you see nothing out of the ordinary.

Entering the coffee shop you see Eve texting, some guy feeling her butt before smacking it on his way out. She jumps and furrows her brow. You mostly notice how her tits bounce when she jumped. You try to shake your head clear.

"Hey babe, you want a coffee or just head to class?" Eve asks you as she kisses you. You slide both hands down her back and grab her ass, pushing and pulling them apart. Your nerves can't beat the sexiness of your bare assed girlfriend. You think you should try to go into the class with a clear head. You turn Eve around and push her forward, she giggles wondering what's gotten over you, and you plant her in a chair. The three other chairs are occupied by random girls, naked, who try their best to ignore you. Once Eve is sitting you pull out your hard cock.

Eve's face goes from playfully happy to somewhat resigned. You don't care, you just start jacking it, so close she could stick out her tongue and lick it. She doesn't of course, just crosses her arms disappointingly. Not disappointing to you as it pushes her tits together and up. You stroke faster.

"Ah fuck Eve, you're so fucking sexy, god I want to fucking use that pussy of yours," she blushes and looks away, still ignoring you. One of the girls sitting nearby gasps at your dirty talk and you realize they've stopped talking and are just staring wide eyed at each other. This pushes you closer to the edge.

You see Eve's mouth press together in discomfort as she waits for you to finish. God, that mouth. She's never really been into blowjobs but you're definitely a fan. You feel hornier than ever, feel your reasoning get cloudier. Her fucking mouth.

Playing a gamble you slap Eve's face with your cock. You see the astonishment in her face as she opens her mouth to yell at you but you're too quick. You grab Eve's head in both hands and start fucking her mouth. She pushes on your legs but you ignore her, intent on using her mouth, just another hole to be fucked. Right before you cum you shove your cock as far down Eve's throat as you can and blast loads straight down. She's gagging for your entire orgasm and you only let go when it's over. She reels back, coughing, saliva and cum dribbling down her chin as she recovers.

You feel that post-nut clarity and prepare for her to rip you a new one.
