I’ve known my gf’s roommate for a few years now and we’ve all become good friends. She is single and the three of us regularly hang out. I spend the night at their apartment a few times a week.

They’re both pretty open with their bodies, changing in front of each other, one will shower while the other is doing her makeup, etc.

There have been a few times where I’ve seen the roommate in her underwear, in a towel, topless from the back. But nothing crazy.

But over the holiday weekend she seemed to get a whole lot more comfortable. First she “forgot I was in the room” on my computer and stripped her clothes off down to her thong to try on a dress for a New Year’s party. My gf jokingly yelled at her and I turned around and got an eyeful of her boobs before she covered up.

Later that night we came home and she was a little tipsy and changed with her door open into just a t shirt and thong and came back out in the living room to watch the ball drop with us. She got under a blanket but made a comment like “it’s nothing he hasn’t seen before”, and my gf just laughed it off.

She goes to bed not long after. and my gf and I begin to fool around on the couch. We’re making out and my gf pulls off my shirt, slips off my shorts & gets on her knees to give me a blowjob. At this point I’m butt naked and my gf is only wearing a t shirt & we’re out in the living room pretty close to her roommates door, but I’m so horny at this point that I could care less.

My gf is sucking my dick and I motion for her to come up on the couch and sit on it. She slips off her panties and right when she starts to swing a leg over to ride me, her roommates door opens and she walks out towards the kitchen. She looks over and gets a full on view of what’s happening and says “oh I didn’t know you were still out here, but don’t let me interrupt!”

I’m frozen and reach for a pillow to cover up. My gf is still wearing a shirt so it’s easy for her to cover up. My gf asks her roommate what she is doing and learns she has a headache and needs some medicine and a glass of water. My gf is directing her where the medicine is all while creeping her hand down to my dick where she starts stroking it under the pillow, keeping me hard.

Her roommate walks back by us getting another good look, and my gf says “sorry we’ll be finishing this up in my bedroom”. Her roommate responded “no problem at all this is hot, have fun with that” and gives me a sexy look.

Idk where it goes from here, but I’m definitely enjoying this new comfort level ;) I’ll be sure to share again if anything interesting happens.
