the cute curvy blonde

I squeezed in behind the blonde. My cock was already hard so I got nice and close behind her so my dick would dig hard into her ass. I heard her let out a little moan.

I reached down and grabbed my hard cock through my pants and slid it between this pretty blonde's ass crack. I started grinding up and down, humping this cutie's fat ass.

I hear the blonde whisper something to her brunette friend and they giggle. I hump this chick some more and all of a sudden she starts grinding back. They giggle again. They're loving this. My cock is so hard that I feel like it could rip through my pants.

I'm wondering if I should slide my hand under this cutie's plaid school girl skirt...
