You love it

"Goddammit, yes! Ok? Yes, I love it. Now please let me masturbate!" You plea.

"Ha! I can't believe this is really happening! Alright, let me untie that eager right hand of yours," Jen teases.

She hops off of John briefly and quickly undoes the rope restraint on your right hand. In under a second of being released your hand is on your pussy, rubbing it wildly. You nearly scream in satisfaction. You can't believe how depraved you are.

Jen continues to laugh at your situation as she climbs back on John. You watch enthusiastically as his dick disappears inside her pussy. She lets out a moan meant in part to mock you, but it only serves to turn you on further. Your body clenches as you bring yourself to an orgasm. It's the orgasm you've dreamed of your whole life. You tilt your head back and relish in its intensity. It subsides a few minutes later and the sight of Jen bouncing up and down on your boyfriend's sexy cock makes you crave another orgasm. You start again, fingering yourself, trying to match Jen's rhythm. You feel so much shame and jealousy but that only makes it feel sweeter. You want every second to feel as good and filthy as this. You look to John trying to see his reaction to all this. He doesn't seem to be processing it and is instead staring at Jen's ass bouncing on his girthy cock. It's too good. Not ten minutes go by before you bring yourself to another full orgasm. But this time you don't even bother stopping. You power through the orgasm with two fingers up your drenched pussy. You don't know how this could get any hotter.
