Take your mom to a house party

"Alright... I know how we can get you some more jizz." She perks up at that, and your cock soon does the same. "My friend Jake is throwing a birthday party tonight. His parents are out of town, so it's gonna be a huge one. Wanna come?"

"Huh? Why... Um..."

"Think, Mom! There'll be, like, a hundred college guys there. If we ask really nicely, I bet some will be willing to donate."

Your mother gasps, looking embarrassed for about half a second before nodding frantically. "Y-yeah. Okay, yes, let's do that. What time? What should I wear?"

Your mother spends the rest of the day asking about the party, worried about every little thing. While the rest of you eat dinner, she's already prettying herself up. After an hour she comes downstairs, wearing the dress you picked out along with plenty of makeup.

"Marcus, are you sure this fits? I can sorta make it cover my nipples, but every time there's the teeeeniest little tug..."

You chuckle as she exposes herself to you. "That's the whole point, Mom. Your mission tonight is to make a bunch of guys hard. How're you gonna do that with your best assets hidden away?"

"Oh... Right, I guess so," she replies with a nod. "Thanks for reminding me, Sweetie. I know I forget things, sometimes, and--"

"Don't mention it," you interrupt her, grabbing a handful of tit and bouncing it a few times. "Goddamn... You're gonna be the hottest piece of ass at this shindig for sure."

"What's a 'shindig' again?"

"...Nevermind that. All I'm saying is that you're gonna get tons of cock--Uh, I mean, medicine."

She nods again, beaming with pride as you shamelessly grope her. "Yay! Thanks, Baby... You’re so good to me.
