I sit naked next to or in front of him and wank his stiff cock - pull the foreskin up and down - oh I know exactly how good it is for him and I can feel that he'll come soon, but even if I talk nice to him I'm quite mean and stop jerking off again and again when I feel his juice rising and then again with a nimble hand the hard cum and when he can no longer hold it I stop mean as I am and ruin his orgasm - only when the sperm juice is already running do I take it I hold it briefly in my hand again .....
