I'll allow you to touch your dick but there will only be two fingers on it at a time. I know how difficult that's going to be with my ass and cleavage taunting you, making you ache to wrap your hand around your dick and pump. That's alright, I don't want it to be easy. I want you squirming and frantically rubbing with two fingers, trying every desperate way to cum. I'll find it amusing no matter the outcome. Either you'll be horny and pathetic enough to cum with only two fingers, or you'll be left aching and begging for more with those blueballs.
