You are such a good cum slut!
Jerk your cock. I want you to stick your finger in your pretty cum glass. I know it's empty, but I want you to scoop the bottom up. There will probably be some goodies left.
Lick your finger. Mmmm, there's your first cum tasting tonight. And you are just loving it!
Milk all the precum you can out of your cock. Scoop it up and lick it!
