He has no idea at this point that I have hair under my arms. My arms are down, and my hands are around his cock, wanking it for all its worth.
I do it to make him go.
Men call it "rubbing the easy one out".
I want him to take his time for when the REAL fun begins.
And then he goes, spewing his creamy white sperm out of his piss-slit and onto the floor. Some of it gets on my hand and on my tits, but I don't wince or let go of his cock.
I'm a good slut like that.
