So there's this guy in one of my college classes I sit next too and he's cute as hell to me. Ive mostly attracted and been attracted to darkskin niggas I just got a thing for them and they like my lightskin ass. But back to the guy in my class it's two guys honestly but the boy in grey sits right next to me and he comes in wearing different kinds of sweats and joggers everyday showing off his nice "bubble butt" One might call it. And he wears these tight shirts where you can see you chest almost coming out. He has a lighter complexion than me and everyday I have this intense desire. I'm not big on oral but if it's ass I'll have you set right every time.. I just want to ask him if he would be cool if I got just a taste of him ass & keep it between us. I always try to catch him after class but he zips right out and never run into until the next time we have class. I try to stay lowkey cuz I'm not the attention seeking type.. Earlier today I almost caught up with him as he was leaving but I couldn't urge myself to speak to him fearing rejection.. I never hit up a guy outside of dating app so this is all very new to me.

I could only manage to spit out a few words "aye T. you got another class" In a shy voice. I can't remember his response cuz I tried not looking directly in his face but I knew he said he was going home. I feel defeated? I guess... I'll definitely try to speak to him again soon!
