Dang, wish I were big enough for that. You keep giving me the best ideas, Snoodle... That would be tons of fun to do to some random asshole in public. Get real close to him, whip it out and swing it right up into his nuts. Usually I'd rather be the one getting busted, but that right there sounds like loads of fun.
Maybe while I'm standing there gloating, his girlfriend can grab my nuts from behind and dig her fingertips in, make me beg for mercy, and then drag me to the ground by my balls. Ooooh, yeah, that sounds fun...
She could always go for that big cock, isntead. If you're gonna be using it like a club, maybe she'd make sure you can't ever do that again? A pair of scissors can work wonders on a tranny that's too big for her britches...
Protip: "I'll show you my dick!" isn't a conversation starter on the internet any more than it is in real life.
