Gf showing off

My gf and I had a party this past weekend. Parents were out of town. party had all but died down just me 4 of my buddies and my gf. So everyone is just hanging out next thing I know my gf reaches for the ps4 controller on the table and her skirt rode up her ass and let everyone have a plane view of her bare ass and pussy… I looked to see if I was the only one that saw it but i wasn’t my buddy Timmy reached out and touched her pussy which caused her to jump but then push into his hand like she wanted it. Next thing I know my gf is completely naked giving handjobs out and getting fucked by r.j. I kinda enjoyed it my gf is like 5 ft 5 maybe 115 pounds blonde hair. I just sat there and watched had no desire to stop it. After it was over she and I went to bed. I then decided to lift up her skirt and see what her pussy looked like. It was all used up and loose it turned me on so much she loved it
