I'm getting ready to unwind in bed while completely unaware that you've climbed your way up onto the foot of my bed. You attempt to sneakily stroke while looking up at my massive ass, but just as I start to get comfortable, I notice you standing there, panicking about what I'll do. You know it's not safe for you up here; too close to me and I could've smoosh you with my ass, too close to the edge and you could've stumbled over the edge, falling what seems like a mile down to the floor. I decide to show you some mercy by letting you stay on the bed, but you're about to get a face full of what you came here for. Be extra careful: my giant bouncing ass feels like an earthquake and the smooshing might push you closer and closer to the edge. Just don't fall off.
