She cuts you a deal

This isn’t good at all! Hateya’s in the driver’s seat here, you have **** but to do as she says or else your grade plummets to the ground! But still, to even show her your bulgy reaction to getting groped by Zoe is too humiliating for any man!

The young scientist must have noticed your inner struggle because she offers you a painful alternative. “Of course I may be persuaded to alter my observation to another experiment if that is to your preference…” The girl bites her lip only a little bit. You can see the eagerness on her usually stoic face. She wants you to agree. It’s a trap!

“I will allow you to cover your front if you expose your-“

“My bare ass.” You finish Hateya’s sentence with a groan. You had a feeling it would come to this. When you caught her staring your ass down in class and openly admitting to it. She’s an ass guy. Or girl. For better or worse.

The good news is that for you, your dick is the most important part to keep hidden. Sure it’ll suck to show a girl your ass cheeks but it’s just a butt right?

R-right?

“Fine.” You grunt, turning your blushing face to avoid hearing Zoe’s excited squeal. Hateya hides her emotions well but even you can tell she’s pleased by your answer.

“Very well. Turn around and exposed your rear end from the back.”

Slowly your turn so your underwear clad ass is facing the two girls and your still quite erect boner is hidden. You then hook both fingers in your boxers.
