I can't fathom why the thought of watching a couple fuck, while knowing that they'll expect me to clean up afterwards excites me so much. I've never done such a thing, but I'm getting to the stage where I can't watch a video of a pussy oozing cum without the impulse to lick it manifesting. It makes no sense, why would I WANT to do that? I'd love to find out whether having such an experience in 'real life' would excite me, or whether it'd take a firm hand the first few times to get me acclimatised to complying with their wishes. Maybe I'd get buzz from being required to perform unconventional sexual roles when in their company, experiencing new things???
If I'm going to be cleanup, I want the cum deep in her cunt so it will take me awhile to suck it all out. In the meantime, I'll suck him clean too before he loses the boner
