When I was at Uni, I had an affair with a married man. I wasn't in love with him, I just wanted the eroticism of making love to a married guy.
One night, I asked him if he had any fantasies. He said that he would love to be inside me while eating his wife out. Now that clearly wasn't going to happen, but I said "Why don't you bring her panties to college and you can smell her cunt while you finger me." I thought that would be the best fix we were likely to get so the next night he did just that. It clearly aroused him but then, half way through I suddenly said "Give them to me." I took them, a small light blue pair of bikini panties and fingered them around until I found his wife's pussy stains. I looked at them a while and then stuck out my tongue and tasted her on them. I had never done anything like it before. He said "Jayne, I want to watch you masturbate and use my wife's knickers to get yourself off." I began to masturbate imagining her pussy and how he fucks her. Then, to my delight, he showed me a photograph of Cath stark naked. I smelt her knickers and rubbed, then I sucked them hard and my whole head filled with her scent. At the moment I came, I pushed her dampness against me.
The next day, when I got up, he had already left for his first lecture. I got up and saw his wife's panties lying on the floor. I picked them up and had an overwhelming desire to put them on. Now, wearing a dirty pair of panties is a no no, but wearing another girl's dirty panties? Hmmmm. I slipped them on and felt myself getting horny as soon as her wetness touched mine. I spent the morning in lectures sensing her pussy right up against my own. That afternoon, I told my lover that I wanted to be fucked outdoors. In public. So we went to a local beauty spot. We walked into the woods a way and I squatted down opening my legs at the same time. "You look good in her panties" he said. "If you like that, you'll LOVE this" and I let myself piss in them. He was on his knees in a heartbeat pulling the material to one side and finger fucking me to orgasm.
FOOTNOTE a few months later, I met his wife. All three of us went out for dinner and I invited them both back to my room for coffee. That night, I got to taste her for real and although we didn't fuck, the three of us engaged in what can only be described as a wank-fest. I fingered her off, (including anally), he fingered us both off and she fingered me. Delicious!
