She doesn't give him a choice

"Fuck it!" Amy growls, stepping forwards and grabbing at James' jeans still around his ankles.

James lets out a little cry, and with Amy yanking at his jeans one shoe comes flying off and the jeans come loose, although remaining caught around his left shoe on his left leg.

"Get off!" James cries, reaching to grab at his jeans, but you give him other things to think of. All the waving and dragging across the floor has caused his Y-Fronts to slip and now his erect cock is flapping around in the air, fully exposed.

With another cry, James reaches down trying to keep his manhood hidden, while still fighting against Amy with one leg.
