Input: Text: this happened a while back, but i just remembered it thanks to reading some stuff on the subreddit.

okay, backstory: so there's this girl in my high school economics class that i sit across from. she's a pretty good-looking black girl, with full hair and a tall, plump body. oh yeah and she got some choice knockers too. so yeah, she's hot and she's also very outgoing, meaning she talks to everyone, including little introverts like me. though, most of the time i just wave and give her an awkward smile. (she also likes touching my hair 'cause it's really curly, but that doesn't really matter.)

so this starts at my house (it's saturday) and i'm feeling kinda frisky, so i pull up some porn and head to town. after i finish, i wipe my hands off with a paper towel and lay down for a bit in the afterglow.

a moment later, the doorbell rings. the thing about my doorbell is that the only way you can hear the thing is if you're on the second floor, and at the time, i was the only one up there. i, without thinking, pull my pants up and go check on the door, i didn't even consider washing my hands. i just thought it'd one of my mom's friends. i wasn't planning on touching anyone.

anywho, i open the front door, and here's the big-tittyed black girl from class! she recognizes me and extends her hand in greeting, taking about some fundraiser that's selling cheesecake.

my combination of my lack of forethought and the fact i'm still coming down from my afterglow made me, without thinking, shake that girl's hand. god knows what horrible things that transpire down below that now defile my hand and, to extension, hers. i break the handshake quickly and proceed to do some awkward small talk before calling my mom out about the cheesecake. mom buys one, and i get one too out of guilt.

worst part is, like i said before, she's outgoing and talks to everyone in class, so almost every day she goes out of her way to say hi. and as always, i wave back, now hiding my shame with my trademarked awkward smile.

also, the cheesecake was pretty bland.
