Wait. What? It doesn't tell me? I-

As you think, you suddenly feel something grow in your pants. What you see happening is a lump snaking past the waistband of your pants, and up your shirt, getting bigger and longer until a large round end of a rod pops out the neck of your shirt. What you feel is something else, as your dick swells and grows in length, with electrifying pleasure as your average 6" cock snakes up your shirt growing to a whopping 30", and a little thicker than a can of soda as it sticks out the top of your shirt.

You worry that someone would see it sticking out, but no one seems to notice, or at least they don't care. You're actually starting to wonder something else looking at your dick almost in your face. Could you... possibly... no. No way you could suck your own dick. And no way you'd actually want to, right? Right?

Your new found titties finally stop growing at an G cup, and your cock once dribbling is now a stream... And it looks delicious as it flows, and with these new tits, it would probably be pretty fun. But all these pretty ladies in the room could also always be prettier, right?
