Обвислі штани, заохочення до дрочки

We're studying together, I'm very grateful for your help. I stand up to stretch, not noticing my pants are sagging so low that it's revealing my ass and pussy. You cannot peel your eyes away. When I go to sit back down I drop my pencil behind the bed, as I'm searching for it, ass in the air, flashing everything, I sense something up, but you don't say anything. I keep searching, asking for help, but still, you just stare. Eventually, I realize, I get embarrassed, but seeing how excited you are for my saggy pants, ass crack, and flashing, I realize in exchange for you completing the coursework I'm struggling with, I can just flash my ass in my saggy pants and encourage you to jerk instead, now that sounds like more fun!
