"play with yourself."

As he says that, he undoes the cuffs from your wrists, placing it to the side for the moment. "Starting with this." He drops the dildo on your stomach and takes the paddle from Tyler, as Robbie watches in wonder - his cock is still out, and is starting to get hard again.

You move both hands to the dildo, and start pumping it in and out of you, your legs splayed wantonly wide, but Michael starts using the paddle on you.

"Not good enough. I know you can do better. Do it like you'd do to yourself if nobody else was around."

You look around nervously - this is a public park, and you've done very well not to be noticed so far - but another few slaps of the paddle on your thighs convinces you, and you have one hand on the dildo now, the other on your left tit, mashing and mauling it, and your close your eyes and imagine it's a guy doing it to you. However, you're rewarded with another hit of the paddle.

"Keep your eyes open. You need to look at us when you do it."

Your eyes still clasp closed in pleasure, but he hits you again, on your stomach this time, and if he does it much harder he's going to leave marks.

"OPEN! Let us see what you're doing to yourself."

With visible effort, you keep your eyes open as you watch the boys. Robbie and Tyler are rubbing their own cocks, apparently enjoying the show, and while Michael's is bulging, he has made no moves to it. Your hand moves up and down your chest wantonly now, savagely twisting your breasts as you relive the events of your day in your mnd's eye - Eddy fucking you from behind, the biker taking you in the shop window, and the looks on the boys faces as they were stripping you and chasing after you for the past hour. You pump the dildo in and out as fast as you can, and you can hear the sloppy noises of your wet cunt gripping it and it turns you on even more - your nipples are pointed upwards and the expression 'they could cut glass' fits here, and you start alternating between your breasts as you feel the explosion coming, and then it happens.

"oooOOOOOOOOOOOOOH!" you shout, and you convulse with incredible energy and your cum empties from your pussy and onto the dildo, onto the ground, and you collapse fully to the ground, breathing deeply. Your eyes shut as you feel exhausted from the high you've just come down from - that's the most pleasure you've ever experienced.

Your lack of energy means it's much easier for Michael to move your arms behind you and recuff you. You're back on your knees again, but even as low to the ground as you are you struggle to stay up. Your arms buck to move to the cocks of Tyler and Robbie but the cuffs keep them where they are, and Michael pushes you back to the ground, and your legs splay out again in the familiar position you were in before.

"I'm not done."
