You and Tessa were sitting in her room as your stepbrother and her stepbrother were downstairs gaming.

“So… you want Preston?” Tessa drags her words. Preston was the name of her stepbrother.

“What? No where are you getting that idea from?!” You say too fast, too nervously.

“Oh c’mon, you eye-fuck him every time he comes into the room, he’s way too blind to notice. Besides, earlier this week, I accidentally walked in on Ethan in the shower. I didn’t know he was in there showering, but I’ve been horny since.” She confesses, Ethan was the name of your stepbrother.

“Ugh, we both want each other’s stepbrothers, what are we doing sitting here and acting like saints?” You groaned.

“{{user}}, you dirty dog… what are you thinking?” Tessa demanded.

“Strip twister.”

Tessa thought and her smile twisted into a smirk.

Perfect.

You guys head downstairs and find Ethan and Preston gaming.

“You guys are gaming addicts, get off those games for once.” Tessa tells them.

“Go away Tessa.” Preston groaned.

“No. We wanna play a game with you two.” You added.

“Will you two go away if we do?” Ethan rolls his eyes, putting his controller down.

You and Tessa nod and explain the game.

“So we’re gonna play strip twister. Whenever someone slips, they have to remove an article of clothing.” Tessa explains.

“But you guys are our stepsisters.” Preston mentions.

“We’re not blood related, it’ll be fine.” You brush off.

They hesitantly agree.

DURING THE GAME.

When playing, Ethan was the first one to slip after seeing Tessa bend over to reach a green. He took off his shirt.

You ended up faking a slip next.

“Omg {{user}}, you slipped! Take off your top.” She beamed. All part of the plan.

You pretended to be nervous and blushed. Although it was a fake blush, you weren’t nervous about anything and took off your tank top. You were now in your bra.

A half an hour later…

You: Bra, panties and skirt. Tessa: Bra & panties Ethan: Sweatpants and boxers. Preston: Only boxers.

“Preston, left leg blue.” Tessa spins.

“But I’ll slip! I only have boxers left!” He shouts.

“Rules are rules. Do your best.”
