When I’ve got a massive throbbing cock at my lips, that makes me my most solid. Or when I’m being fucked just right and the top is doing his thing perfectly, that when I get my hardestYou know the one, when your cock feels like it’s pumped full of high pressure fluid. And you’re working your way inside that pussy that’s tighter than a fishes arse.

And last but not least, scratching and biting if the nipples!
