Improvise

Max quickly grabbed Zack and threw him on the bed, she the mounted him.

"Pull out your dick out, quickly" She said.

"Wha?"

"Do you wanna get us killed?" Max lifted herself up so that Zack could unzip and pull out his cock, she threw off her wet coat and ripped off her thong earning a groan from Zack as he looked at her shaven snatch. She put her hand to her bra and slipped it down exposing her full plump boobs. Next she ripped open Zack's shirt glancing down at his chiselled body.

"Fffck" Zack groaned as Max sat on his cock, her pussy lips rubbing against the under side of it. Max's eyes widened as she felt Zack's cock start to grow between her legs he was immense in size, 10 inches at least. She quickly threw her head back and grinded her pussy against his erection pretending to fuck him as the door opened.

Nikoli walked in the room but stopped dead in his tracks as he saw Max and Zack. He simply smiled then walked out again.

Max stopped moving looking into Zack's eyes. Her pussy made the under side of his cock damp as her juices leaked out. He was throbbing beneath her, and all she could think about was to grab his cock and shove it in side her then fuck him till she burst.

Zack was gonna blow his load right there. Max sat on his lap breathing heavily, Her perfect tits rising and falling as she breathed, perky nipples standing erect. His cack ached as it pressed against her moist fleshy folds. He wanted to fuck her, he didn't care if she was his sister, she couldn't just strip naked and tease his cock like this. But she had to improvise, think quickly, if Nikoli caught them they'd be dead.

Max and Zack stayed very still on the bed, this was one fucked up situation, they both wanted to have sex, but neither were willing to make the first move...
