Bob's probably not going to get his jeans down much farther if John's legs stay wrapped around his thighs, but it's not as though John actually wants to prevent that from happening after all, so he grins in response, propping his feet up on the bed again. "Forget 'ow to get your own trousers off, 'ave yeh squire? Sounds like it might be a bit awkward in certain circumstances."

John could of course use his hands to help, seeing as how they're already right there so to speak, but he's rather enjoying grabbing Bob's arse, so he'll just keep on doing that for the moment, gazing at him hungrily as the jeans inch down.
