Rich comes to with your giant cock shoved up his ass and filling him with hot cum. His hand fumbles in a box under his bed.
You pull off the mask, and he plants a sticky rubber disk on your belly. It's a valve like on a rubber raft or inflatable pool toy.
"You bastard, you couldn't keep your hands off my masks. Well, that's not the only "novelty item" I've got. You're going to find out what it's liked to fucked now too!" Rich said pulling the valve open. The sound of air rushing out is immediately obvious. You fell weak and swoon. You fumble with your deflating fingers trying to close the valve, but they're too weak. You are collapsing in a rubbery heap.
Rich stands with his legs spread apart naked and groaning in pain. "Oh, yeah, you're going to get it. I'm taking you to the Gay Pride Party at Gamma house. Then maybe I'll change you into a rubber inflatable sheep and take you to TKE for their hellweek, imagine a hundred pledges demonstrating their technique on you. Only 25 make the grade, and the sheep love part of the pledge test is 20% of their grade. Heck, I may never change you back, roomie!"
