A tall skinny girl

"Come in!" Ashley shouts.

"Rachel!" You overhear Ashley shout happily. "So I caught this total idiot hot guy dealing valadeent today trying to sell it to one of our undercovers. I've got his stash, we'll dole out later. For now, he's tied up in the living room, if you want to go check him out. He's pretty well hung, and should be A LOT of fun for us."

"Anyway, I've got to go shower and freshen up before all the other girls get here. Make yourself at home. What's mine is yours."

Rachel thinks about that for a second, then walks into the living room, and sees you all tied up.

"Well what have we here?" says Rachel eying you like a piece of meat as you're helplessly tied up, completely ****. You struggle for a bit, trying to get out of the handcuffs, but to no avail.

Rachel is about 5'9" brunette tall with size B boobs, a little on the skinny side, and from the look of it, she's been hitting the valadeent lately, and needs it.

She instantly straddles you.

"I can't believe Ashley would leave you all helpless and tied up like this," She looks at you with sympathetic, caring eyes.

She pulls out a knife and you naively think she is going to cut you free.

Then very matter-of-factly she states-
"All these clothes on, they'll just get in the way."

She slices off your shirt and starts caressing your chest, pulling at your nipples from time to time and sucking on your neck. You're helpless to resist, as the skinny chick starts slowly grinding her hips on you.

Her breathing picks up and she expertly cuts through your pants and boxers, leaving your dick out and exposed in the air.
