Well when I was in college, I lodged with a mature couple. It was just nicer than being in halls and I could see my boyfriends when I liked, relationships didn't much get in the way of college work. I've always been a girl with a high sex drive and I guess I've always been into erotica. It's what I did my thesis on, sexuality. Anyway, one night I came back from college and a couple of guys were there, in the lounge. There had been some kind of heated discussion, Bill my landlord had a face on him like thunder but Jane seemed quite relaxed, slipping her shoes off and waving her bare feet at them. Not really my business, I thought nothing of it until a week later. Bill asked me a favour. Could I go out tomorrow night and leave them be, there were visitors coming over and the business was private. I said, yes fine, I'll go and see a boyfriend. On the night my boyfriend stood me up, so I drove back. The doors were all locked and nobody answered the doorbell. So I looked in the window. There was Jane, naked and bending across the armchair. Those guys were both naked and with her. She was sucking one guy's cock, encouraging him by stroking his balls. I saw the other guy behind her pull out of her pussy and begin to push his way into her arsehole. He opened her cheeks with his thumbs and shoved himself in, right up. Then I saw Bill. He was sitting in the other armchair, pants down and slowly pulling himself off. "Please no Jane, not like this!" Then the guy being sucked by Jane seemed to cum. He began bucking his hips up and grabbed her hair. I heard Jane giggle. That was enough, I went back to my car and rubbed myself off, I climaxed like crazy! Everything was quiet when I returned around midnight, no sign anything had happened but I'd seen it!
