Good for Something
Oh, there's your little teensy balls too! I forgot about those...I can see them from this angle. Well, balls aren't much use without a cock, are they? I guess if you keep them shaved, you could write on them too, but maybe there's a better idea. What do they remind me of...?
I know! Marbles! Why don't you try flicking them like marbles a couple of times?
But that's not very useful...
Maybe your girlfriend can use them to help her exercise. She'll want to stay in shape for all the fit young guys she's going to meet. Oooo, just thinking about that...
They sort of look like little punching bags. Try them out! It's obvious you haven't been to the gym in a while anyway. Start with quick little punches, like dodging around a boxing opponent. Then try some harder ones. You should get your itty-bitty thingy involved too, slap it like you're spiking a volleyball.
