Reluctantly you get on

Moaning to yourself you straddle the bike, sitting up as far from his greasy body as you can get.

"Sit right here," he says, and takes hold of your trim middle, pulling you against him and sliding you down his wet furry body. You shudder as your hands slide through rolls of fat, and then you hear a click.

"What?" you start to ask, trying to shift to look, but you can't seem to move your body in any direction but up or down.

"Better sit down," he tells you, and starts the motor. You hear shouting from the alley, looking back in time to see the two cops who'd been about to arrest you charging out, followed by what looks like a cross-dressing bear.

"Jesus Christ!" you cry out at the site, and realize the two officers recognize you.

"Feels good, don't it?" the biker yells in your ear, in spite of his mouth practically drooling into it. "This'll make it feel better he says, and you feel his hand squish down between you and him, reaching under your tight butt.

A moment later you're horrified to feel two things. One is quite clearly his cock, pressing against your asshole. The other is that the dildo inside you starts to vibrate, and the bristles twirl, feeling like someone's turned on a washing machine inside you.

"Stop! Stop!" you yell, half-crouched on the bike, determined not to ever sink down on either object.

The biker just laughs and roars forward with increased speed, while a siren starts off in the distance behind you.
