sissygasm 

a submissive, feminine male's orgasm achieved exclusively through anal stimulation, no hands, oral, nothing. This can be done with toys, (dildos, strap-ons, etc.) but most commonly involves a bigger, more dominant man brutally pounding the G-spot in the sissy's ass until they cum hands-free

After getting absolutely pounded by his hook-up for an hour, Alex had a sissygasm so large, it made his eyes roll into the back of his head. Now, he's not sure if he can ever go back
