My Girlfriend's Girlfriend

I was at a party about a week back with my girlfriend and a few friends. Well by the end of the night we were all too tired to go home so we asked if we could crash at the house of the party. This turned out to be ok so my girlfriend's friend (we will call her Stephanie) and myself, all jumped into a queen sized bed to share for the night.

I stripped to my boxers and they slipped down to their bra and panties. We got under the covers, me being in the middle of the bed.

My girlfriend fell asleep straight away, I turned to face the back of Stephanie, she grabbed my hand and put it over her waist in the spooning motion.

She slowly moved my hands up to her breasts which are quite large, this got me hard. I slid my hand through one of her bra cups and I was gently caressing her nipple.

My stiff shaft was jabbing her pantied ass, she slowly slipped her panties off, so I let my stiffy pop through the hole of my boxers.

My cock was now pressed up against Stephanies nice bare ass, she began rubbing her ass cheeks over my cock, she licked her hand and slid it over my dick, she started to move her ass faster and faster over my cock untill she felt I was about to cum.

She quickly rolled over, exposed her breasts and cupped her hand over my cock. I shot loads and loads of cum all in her hand to leave no mess around.

I quickly frigged her off, fingering her pussy to a climax. I haven't told my girlfriend about me and Stephanie, but almost every day I masturbate into the panties Stephanie gave me from that night.
