She was a tall sexy 20 year old brunette art student who also did some part time modelling. All she was wearing was one of my roommates t-shirts which barely covered her ass. Her breasts were large but perky. I suppose she thought that since I had seen her in all her glory the night before that she had nothing to hide. She had made her boyfriend (my roommate) and me a cup of coffee. We were sitting at the table in the dining area. It was a bit awkward for me after walking in on them fucking. She got up and went to the kitchen. My roommate was excited with a naughty look in his eyes. He leaned over and whispered ‘she wants round 2 and she wants you to watch’. The dining area in our small flat was just an extension of the lounge. The sleeper couch was still folded out from the night before. When she returned from the kitchen, he stood up and took her by the hand and lay on the sleeper couch. They started making out and it wasn’t long before he was going down on her and making her moan. She had one hand on his head and the other under her t-shirt playing with her breasts. I could not believe what I was watching. He looked up and asked me to fetch him a condom before burying his head between her legs again. Not long after I returned with the rubber she let out a scream, her body shuddered and her legs went limp. He slapped on the rubber and got on top of her. His tall skinny body started pounding away and she started groaning again. I was sitting at the dining table, my coffee was cold and I had a raging hard on. They changed positions and she got on all fours like when I walked in on them the night before. She motioned for me to come sit closer. As I went over, my roommate said ‘come check out this amazing view’. Her hips seemed wider than they were and then tapered into her narrow waist. A perfect hour glass figure. I sat down on the other couch and continued to watch. Her t-shirt was pushed up to her shoulders and I could just see her breasts bouncing in and out of the t-shirt. While being taken from behind she made eye contact with me. It was an incredible moment which seemed to last for ages. She told me to take out my dick. I did not need to asked twice. I started stroking my dick but was afraid of cumming too soon. She was moaning while watching me pleasure myself. My roommate did not seem to even notice me while fucking her as hard as he could. As he came while still inside her, I let go and shot my load. They collapsed and we all started laughing. She was late for a photo shoot and had a quick shower before running off. My roommate and I spent the rest of the morning discussing how awesome she was.
