Sex with my GF while she wears her roommates panties [MF]

This is a story about me and my now wife (Laura), then GFs college days. I met her the summer coming out of my sophomore year, she was a year younger. We met on the internet, I was on campus and she was back home, so we only saw each other a few times that summer. What we did do was spend a lot of time talking over AIM (this was clearly a few years ago).

One thing I’ve always loved, for as long as I can remember, is sexy panties. I absolutely go wild over a hot thong and bra. Laura, amazingly didn’t own any things before she met me. We quickly changed that over the summer.

The next two years was filled with amazing, horny, college sex. There were some weeks we fucked every day. Her panty collection exploded with all sorts of sexy things I picked out for her, or she bought because she knew I’d like them.

When it was time for me to graduate, Laura had another year left. I got a job in a city about three hours away. Not perfect, but still pretty manageable for weekend trips. I would end up going back almost every weekend.

While we were apart there were many long nights of AIM chat. It was hard to get used to no longer having sex every day, so we naturally had lots of dirty talk. One of those nights, when she asked me about any fantasies I had that I hadn’t tole her about, a forthright answer came out: “It would be really hot to hear you tell me about any times you saw your friends change”.

To my surprise, she was actually into this. The first thing she told me was seeing her freshman dorm roommate, Jordan, change. Her descriptions was basically something like this:
“She would always come back from the shower in her robe, then sh’ed let the front open and she’d pull on a pair of panties. These were usually cotton string bikinis, with stripes on them. Her bras had a little adding, and were front hook. When she would “go out” she always had on a denim skirt, and a tank top or tube top. She would wear a strapless bra, either white or black. Going out was the only time I ever saw her wear a thong, and it was the only one she had I think. It was white, with flowers. It didn’t have the string straps, but was a little thicker on top.”

That was the moment I had always dreamed about- it was the next best thing to being able to watch a random girl change, hearing my GF tell me all the details she had seen. I was in heaven.
I asked about her second roommate, Anna. Anna and Laura had lived in a dorm together for a year, and were currently sharing the same apartment. “I never really saw her change, she was always really careful, and either changed in the bathroom, or with her back to me and a towel or robe between us”.

“Ahhh ok,” I said “You know, you live with her now, you could always find a pair and let me see”
Agin, to my surprise, I got an affirmative.

“Just a minute” Again, this was back in the aim days, so things took a little longer (think digital camera, then having to transfer a picture), but after a few minutes I got a file transfer notification. I downloaded it, and holy fuck, there was a thong on a bed that I had never seen before. It was green and black, silky, with little straps, size “M”. She had really done it, gone in to Anna’s room and taken a thong to let me see.

I was incredibly turned on by this, and getting even more turned on by the fact that Laura seemed to be getting turned on by it. I kept pushing. “Will you wear them for me?”
“Hold on”

Fuck. I sat there looking at the picture of them laying on the bed, my cock in my hand slowly rubbing, wondering if she would really do it. Eventually i got the transfer notice again, got another pang of excitement when I realized it was a .zip, and found four or five pictures of Laura wearing that thong. Laura normally wore a Xs or S, and these were medium, so they didn’t fit perfectly, but that honestly made it hotter. sexy reminder that these weren’t really hers.

That week we explored her room some more. Most of her stuff was actually not sexy at all. Like really not sexy. Hanes her ways full backs. Icky. But there were some thongs. I saw my GF model them all for me. Bras too. The bras were interesting, Anna was a C, Laura an A, so they looked huge on her. Again, just a sexy reminder that they didn’t belong to her.

We were coming to the end of the week, and I was ready to make my trip to campus. I knew the sex was going to be amazing that weekend, because this new found kink was driving us both wild. I decided to ask the final question: Will you wear them while we have sex?

“Hehe, yes” was the answer. That became the longest two and a half hour drive in my life (and I sped wildly).

We were lucky in the fact that Anna had a BF, and spent most of her time at his apartment, so Laura and I almost always had the place to ourselves. When the time came, we locked the main apartment door with the chain- this would let me get out of her room even if she did come home. I went into Anna’s room, it was a complete mess. Hardly any of her clothes were actually put away, most were in baskets and piles around the room. Her panty drawer had two to choose from- the first thong I had seen Laura wear, and a new one, with the tags still on.

I chose the first one I had seen, the green and black, and came out of the room and handed it to Laura. She smiled, and went into her room. It only took a minute, her door opened a crack, and her hand came out, motioning me in. I came in to find her wearing nothing but that thong. I looked her over for a few minutes, then grabbed her and started making out while we stood up.

She had one of those sliding glass mirror closets, which was absolutely perfect. I could stare at her ass in that thong while we kissed. I was soon naked, and having my cock jerked while we made out, then I was on sitting on the edge of the bed. Laura got on her knees, and again, I was treated to the view of her sucking my cock while I stared at her ass in the mirror.

I got to me feet, and pulled her up, giving her a light toss onto the bed. The thong stayed on of course, I pulled it to the side, and slid in. Holy fuck, so was insanely wet. She was as turned on by all of this as I was.

I was on top now, pumping in and out, her legs wrapped around me, when she had her first orgasam. I flipped pulled out, and laid down, then guided her onto me, letting her ride me, while I grabbed her ass and played with her tits. The second orgasam was quick in coming.
Now it was my turn. I was on top again, but this time instead of fucking her I rubbed my cock on the out side of that silky thong. She was still turned on, enjoying the feeling of me being on top and playing with her tits. When she said to me:

“do you want to cum on Anna’s panties”

I completely lost it, and in fact, shot a huge load all over the front of her panties (and her stomach). She actually slept in those, with me naked next to her. Laura kept them all weekend, and after I left, she washed them and out them back in the drawer, with Anna none the wiser. This started a pattern of me coming over for the weekend, going into Anna’s room, and picking out what I wanted Laura to wear for me. It was a fun year.

We’ve gotten the chance to play with some other panties in a similar fashion since, but have never had the easy access of sharing an apartment. I love my kinky girl!
