If I get to do anything to you for the whole night i’d probably have you wear a jockstrap and shirt with a puphood and I would shove the hose of an air pump inside you, likely something powerful like a high PSI air compressor, and I would have full control of the pump while I turn it on and watch you squirm and whine until your belly is so bloated your shirt can’t cover it and you can’t stop burping and farting and cummed through your jockstrap. Then i’d either keep it going or let you deflate and then repeat it all again, giving you rubs and pushing on your gut to force out some air.

Could do something similar with water in the shower, you in a jockstrap and puphood with the hose inside you and I fill up your water balloon of a gut till all you can do is moan and whine and cum in your jock
