stepAUNTIE'S TABOO TUTORING METHODS

You’ve just arrived at your STEPaunt’s office hours (she’s a professor at your school), and she's expressing concern that you still only earned a C- on your last quiz, after weeks of tutoring from her. She really shouldn't even be doing this, since you're not in her class; she should be reserving this time for her own students, but you're her favorite STEPnephew and she doesn't want to see you fail because of something she could help with. She briefly calculates what grade you’ll need to earn on the remaining tests this semester and concludes that at this point, you need to earn Bs or better on your tests in order to pass the class. You express that you think you can do it with her help - after all, you heard that her students earn much better grades on average than the students in your professor’s class. Your STEPauntie confirms that that is indeed correct, but then pauses. She gingerly explains that what she usually does to motivate students at this point...is offer an oral sexual favor as one final push to earn a passing grade. She immediately assumes you don't want to do that with your own STEPaunt and advises you pull as many all-nighers as you need to to earn those Bs. But you surprise her and hesitantly state that if it works for her other students, you're not about to decline since you really don't want to re-take this class. She's a bit taken aback, but agrees to it if it's what you really want. She kneels. STEPauntie unzips you and begins teasing your cock with her lips and tongue. She’s barely gotten started blowing you when one of her students knocks. She spits your dick out and yells to the other student to hold on a moment. She sends you on your way and tells you she'll finish you if you get that B next week. The next week, you come back into STEPauntie's office, proudly waving your test around because you did it - you got an A! STEPauntie is very happy, but her happiness soon seems tempered by sheepishness. She reveals that, actually, she forgot to tell you that students who earn an A or better get…more than just a blowjob. Normally, when a struggling student earns an A, they fuck in her office to celebrate. You sheepishly say you're not sure about that, but you will take her up on her offer to finish that blowjob. STEPauntie kneels again, sucking and slobbering, and it's not long before you're desperate to put it inside her. You breathlessly ask if you can, and STEPauntie hops her ass up onto her desk, legs spread for you. You fuck her until she cums, her hand over her mouth, as there are professors, students, and TAs milling around the hallway outside. STEPauntie wants to turn around and take it from behind before you cum, so you flip her around in doggy and keep pounding her against her desk. A student knocks just as you’re approaching the edge, and STEPauntie tells you to cum inside her so she doesn't have a mess to clean with a student waiting outside. You gladly do as you're told, STEPauntie quietly begging for it as you fill her up. Once your load is inside her, she quickly shoos you out of her office, telling you she'll see you soon to check on you before finals.
