This spring my girlfriend and I went to Europe for a month staying in hostels everywhere we went. I'm 31 and she's 30, we're both athletic, and stylish urbanites. When we were in Prague the hostel we stayed in was an old dorm, with our own private room, however the bathrooms and showers were located at either end of the hallway.
As soon as we both went to use the bathroom we discovered that it was cooed seeing a young woman and then, a few seconds later a young man file out. The shower room was full of mirrors, sinks and several large, fairly private showers. We laughed at this but it was nicer than some of the other facilities we'd stayed at.
After we got settled in my girlfriend said that she was going to take a shower and invited me to come along. I said I'd be there in a minute. When I arrived I saw her clothes hanging on a hook next to the shower on the far end. I undressed, looking around to see if there was anyone around, and then slipping in. We soaped and washed each other, playfully kissing and touching until my cock was rock hard. The shower curtain wouldn't close all the way because two or three of the hooks so I kept any eye out to see if anyone had come along. My girlfriend began stroking me as we kissed, eventually sitting on the small bench inside the shower and slowly guiding me in and out of her mouth, making me tingle all over as she sucked me. After a minute or so of this I peeked out to see if anyone else was also showering. I saw a shower directly across the way was on and a guy in his mid twenties was stroking his soapy cock watching us. As far as I could tell he could only see half of my girlfriend sitting on the bench and my cock slipping in and out of her mouth. My girlfriend and I have a serious naughty streak so I leaned down, kissing her and whispering in her ear that we had a fan.
"Should we give him a show?" she asked.
"Sure," I said.
I tugged the shower current open about half way so he could get a clear view of her sucking me and then slid my cock back in her mouth. Slowly but surely I began fucking her mouth, pumping deeper and deeper, making her take as much of my swollen cock as possible. As I reached down, playing with her pussy under the hot water I looked over seeing that our fan was leaning against the tile wall of the shower, stroking his cock with soap to the same tempo I was fucking my girlfriend's mouth. I leaned down and kissed her deeply, fingering her pussy. I could feel how swollen and turned on she was getting.
"Do you like knowing that he's wishing you were sucking his cock?" I asked.
"Yes, it turns me on a lot," she s aid
With that I turned her around and bent her over so her hands were flat against the bench, her hot, curvy ass pushed back. My girlfriend tugged open the curtain a bit more so he could get an even better view of me fucking her. I began rubbing the head of my cock back and forth against her pussy, slipping just the tip in and out, feeling her push back into me, wanting more. From time to time s he would look over, watching him stroke his cock, which I could tell she loved. Slowly but surely I began pounding her, gripping her hips, giving her lovely ass a couple of smacks from time to time. She reached down and began rubbing her clit, moaning for me to fuck her, alternating between watching me slide in and out of her and our fan stroking his cock, pumping his hips back and forth like he was standing behind her. I leaned over and began biting her neck.
"Do you like someone watching me fuck you?"
"God yes, I love it," she whispered back.
Pushing her against the shower wall, I pounded her until she came and I exploded all over her ass. After we kissed deeply and passionately for a moment. When I looked over I noticed our friend was gone.
As we dressed to go out we talked about how hot it was to be watched and how we'd have to take another shower and get "caught" in the act. That night we a few drinks and then went dancing. My girlfriend loves for me to grind and tease her on the dance floor before taking her home and sucking and fucking the hell out of her. Often we don't even make it home before we go at it finding some random place to fuck.
