19 and ready to go

When I was 19 I had a girlfriend who I would give it o on a regular basis. I was her first boyfriend and she was a total virgin, Didn’t know how to give a blowjob and sex was pretty lame.
As our relationship grew she got better and things were ok but her best friend Lyne would tell us stories of where she’d pick up a guy and blow him at a party or take her dog for a walk and end up getting railed by a neighbour a few streets over. These stories always made me horny and would often Fantasize about her, while fucking my gf.
On a random Thursday night Lyne and I were at Sharon’s place to watch a movie it was summer so we all had shorts and T-shirts on, Lyne’s were cut off sweatpants she stole from a guy she screwed one night when she couldn’t find her pants.
My gf had a bad habit of starting a movie and falling asleep and just like clockwork she was out. We told her to go to bed and and we’d lock up when we were done cause we were 1/2 way through it and wanted to see the end. I kissed her good night and tucked her into bed.
I returned to the couch and because of the air conditioning got under a blanket and resumed the movie.
