Didn't Dean ever pay attention in biology? Actually, no, don't answer. Sam could imagine Dean spent most of his lessons either groping the one skin covered breast of a plastic display model, playing with the gas tap, or making out with pretty girls in the storage room. Sam smirked and rocked his fingers to catch that same sweet spot again. "What? You mean that?" He did it again.
His smirk grew. Oh, this was just too good. His brother practically squirming under his touch. Talk about a power high. God, it made his cock ache. He needed to fuck Dean so bad. His patience was fast depleting.
