The big day is finally here! Your teacher has been leading you to this day - the day you didn't even know you were waiting for: the day you finally take a real cock in your asshole. Your teacher has been instructing you on how to stretch and fuck your ass, using a strap on, getting you bigger and bigger toys to put in your ass. She knows exactly what you want - she always has. She's been gently instructing and encouraging you to embrace your basic nature: a bisexual, cock-craving slut.
First, she has you get onto all fours and start licking her holes, just how she taught you. As you lick and worship her perfect pink holes, she tells you exactly what she has in store: three different cocks, each bigger than the last, are going to come into the room and fuck your virgin ass while you keep eating her pussy. She wants to feel you get fucked, feel it travel through your body, the energy of their dicks thrusting in and out. You're nervous, but she promises you that everyone involved is interested in making you feel good...and by good, she means making you feel like the utter slut you absolutely are!
The first cock enters the room and takes his place behind you, pressing the hard head into you rosebud. Teacher Bettie tells you to relax, her soft, soothing voice making your body loosen, and the cock behind you pops in, pressing against your prostate and making your cock drip. Bettie has a big, thick black toy that she slides inside herself as she leans back and watches you get fucked, making you taste her hole off of it periodically, sucking her toy while you hole gets fucked by one, two, three cocks. After the second cock, Bettie slides her big toy into your ass. It used to be so big in there, but now it slips in easily! She gets the two loads all over the toy and then sucks it clean. She loves what a slut you are for her!
The third cock is huge, spreading your hole open and making Bettie squeal with amusement and genuine pleasure. Seeing your holes fucked for her makes her so horny! She makes you beg for cum, then commands the man to cum, telling you that once you feel that third load in your ass, you have to let your throbbing member cum!
