Desc: Erotica Sex Story: Ever since I met my boyfriend Triss, I had less and less time to meet my girlfriends, but somehow I always remembered Martina's words when she once said that I could not "cover her in jizz". So I finally wrote her an email asking if she had time so I could "introduce" Triss to her. She was happy to hear from me and looked forward to it.

Ever since I met my boyfriend Triss and it got serious between the two of us, I had less and less time to meet my girlfriends, but somehow I always remembered Martina’s words when she once said that I could not “cover her in jizz”. So I finally wrote her an email asking if she had time so I could “introduce” Triss to her. She was happy to hear from me and looked forward to it.

We met in a larger city this time and had set a certain parking garage as our meeting point, from where we began walking through the city centre. Martina liked Triss, but what Triss thought about her was not immediately clear to me. He was nice, but he was nice to everyone. Other than that, he showed no particular emotion. Finally, we went looking for a café again and I began to talk with Martina about our usual topics. She was a little embarrassed to talk about her sexual problems and fantasies in front of Triss and I didn’t want to make it uncomfortable for her. Triss was understanding and laid back as much as he could.

She seemed to go through a rougher time than she would let on, but between the lines I could hear she needed someone to talk to and had missed me. I felt sorry for her, and guilty for not having contacted her in so long. On the other hand, she could’ve messaged me as well. Anyway ... with time she began to relax some more and noticed she could talk to me as usual, even in Triss’ presence. Somehow his male presence seemed to be good for her, and she started to laugh and joke about “us women” and our strange problems. Triss was calm as usual and had the right answer to almost everything. I held her hand and tried to show her that I was there for her.

I told Triss before we got together about my lesbian side, and that I probably wouldn’t lose that. He didn’t seem to mind and he encouraged me even to stay as I was, and do as I used to. We agreed to tell each other right away when we did something the other couldn’t tolerate, but so far neither of us had made use of that. So it also didn’t seem to bother him that I liked Martina and caressed her and held her hand while she spoke. Somehow everything was very natural, which I liked a lot.

After coffee we walked some more through the city. I chose our way to lead us past some sex shops, which had the desired effect on Martina. She stopped and stared at the windows, while I still held her hand. I noticed it getting damp and felt what she needed. “Let’s go inside,” I proposed. She said nothing, but followed me and her eyes lit up. Triss came along behind us.

The shop was a little brighter and cleaner than was usually the case. From the entrance a staircase led up to the usual stalls, and a side entrance led to the actual store. Martina and me walked through the toys section while Triss browsed through the porn movies. She stopped at the dildos. “Which ones do you have?” I asked.

She blushed. “I just have one,” she said. “And that one’s secret.” She pointed at a golden shiny metal vibrator. “One like that.” I nodded and caressed her breast. She breathed in deep and said: “You know exactly what I like, Kat.” I smiled.

She looked down in the lower part of the shelves, where the special toys were. “Wow,” she said. “Something like this would be cool.” She picked up a dildo that was almost as big as her lower arm.

“Do you think that would be fun?” I asked.

She looked at me with her slutty expression. “If I can get your hand in, then I can get that one in too.” Somehow she was right. “I’ll buy it,” she said decidedly. We went to the sales desk where we met Triss again.

“Found anything?” I asked, while Martina paid.

He shook his head. “Modern porn is just joyless,” he said. “Nothing for me.” He eyed Martina’s new purchase as the assistant put it into a blank plastic bag. “Seems you had more luck,” he said.

“Depends,” I replied and took Martina’s hand. “Wanna try it?” I whispered to her. She looked at me incredulously, but said nothing. We went to the exit, and I led her upstairs to the stalls. Aside from the “normal” ones, this shop had a “partner box”, which was double as wide as the other ones. That was the one I led her to. Triss hesitated, unsure what to do. “What’re you waiting for?” I asked. He shrugged and came into the stall with us.

Inside was a wide seat with leather upholstery, and a screen with coin slots at the opposite side. Besides that were tissue dispensers and a trash can, which smelled faintly of sperm. When I closed the door, Martina placed her bag on the seat and I grabbed her tits right away. She looked at me surprised, then at Triss, but let me have my way. As usual, she wore a tight top, this time a simple black t-shirt with a leather jacked over it and again a tight pair of jeans. Flat shoes to go with it. I had a flowery silk blouse and nice loose brown denim pants on, and wore a warm coat. It was autumn, after all.

I didn’t wait for her to take off her jacket and just pulled up her shirt until I could see her tightly filled bra. She wore naughty lingerie which only covered the bottom part of her breasts and otherwise showed everything, so I didn’t bother to take it off and started sucking her nipples right away. She moaned. “Oh Kat,” she said. “I need you so, my goddess.” I grabbed her butt and pressed her down on the seat. She sat down and looked up at me as I got out of my coat and opened my pants, sliding them down.

She stared at my pussy and leaned in to lick it. I turned halfway to Triss and motioned him to come next to me. As Martina’s tongue slid through my pubic hair down to my clit, I reached between his legs and noticed a distinct bulge in his pants. “Don’t you want to give him a little more room?” I asked. Without a word he opened his belt and pulled his pants and underwear halfway down, until his cock was visible.

Triss was circumcised and despite that, or because of it, very well endowed. His shaft was nearly 9 inches long, which would fill me up nicely. His dark blonde pubic hair circled his cock and balls, and when Martina saw it, she began to purr: “Mmmh, your man looks appetizing.”

I grabbed her hair and pulled her head back. “And you’ll see how appetizing he tastes, slave.” She nodded. I guided her to Triss’ crotch and she caressed his dick with her fingers gently before wrapping her lips around its tip and starting to suck.

Triss moaned. I looked around and noticed some conspicuous holes in one side of the stall. Besides that, there was some motion in the stall on the other side. I went there and spread my legs in front of the opening, pulling my labia apart. If somebody was watching us, they better get something out of it. I inserted two fingers into my slit and moved them a few times in and out, until they were nicely wet. Behind me, Triss was moaning more and more while Martina was humming softly and continued working his prick.

She definitely was starved for sex. I suddenly noticed another hard cock coming through the hole from the other side. I went back to Martina and pulled her head back. Saliva was stringing between her lips and Triss’ wet penis. I led her to the whole in the wall and she bent forward and began sucking the other cock as well. It was shorter, as far as I could see, and had foreskin, but she didn’t mind. While she leaned against the wall and licked the head carefully, I opened her tight jeans and pulled them down under her ample bottom, until they fell to the floor.
