Give her some pleasure

You move back from her and bend down to her ass. It's glistening with your precum, and you lick some of it up. It tastes... nice. You lick again, and Crystal makes a quiet moan. You grab her ass with one hand and take a bigger lick. You start planting kisses all over her ass, and she spreads her legs slightly. Her cock hangs down between her legs, and you reach down to your own and wipe up some of the leaking precum. As you lick up and down her asscrack you reach through her legs and grab her cock. You start to gently stroke it with your slick hand, feeling it thicken in your hand. Crystal moans, and pushes back into your face. You stick your tongue in, licking and swirling it around. You reach your hand down to your cock again and wipe up some more precum, but this time you slurp it off your palm.

You bend down again, but lower this time, and start to lick Crystal's balls, sucking them into your mouth. You reach up to slide a finger into her ass and are startled by the sound of the laptop slamming shut. Suddenly she pushes back and you lose your balance a bit, falling sideways on the bed. You look up and Crystal is standing over you, tall and powerful, her erect cock throbbing. A bead of precum glistens on the tip. You lick your lips.

"You're about to get it, you little tease!"

"Please, daddy! Be gentle with me!"
