You get off the bed and quickly strip, aware of her approving gaze on your body. You return to her after applying a little lube, kneeling between her spread legs, completely naked, your hard cock giving away the extent of your arousal. You slide your hands underneath her, lifting her up a little so her ass can take your hard cock...

She groans loudly, wriggling on the bed as you push your cock into her little ass, filling her completely, pushing slowly inside her... you reach around, one of your hands going to play with the chain between her clamped nipples, the other to play with her pussy and clit... she moves with you, as aroused as you are... and as you move together, she moans into her gag...

You pull at her nipples, you press a finger against her clit and you pump into her ass, moving faster and harder, harder and faster, your hard cock filling her tight little hole... she moves with you, matching your thrusts...

And then it all becomes too much for her, and she cums, moaning and wriggling on the bed, her muscles gripping you hard as you continue to pump... and then you cum too, still thrusting into her ass, filling her completely... and you collapse together, panting, spent.

Your choices: Be nice or Be nasty.
