In my last year I college, I was renting this crazy apartment in a huge Victorian mansion. Apparently, my apartment had been the carriage house prior to being converted into living quarters. The result was that my unit was long, like some of the apartments in San Francisco and New York, where room after room went in series. My girlfriend was spending the night and we were fucking. She heard a sound, a sound of someone on the other side of my bedroom wall.
She silently expressed her concern and had me listen. I did hear someone moving and then go still. I picked up my jeans and pulled my boots out of closet and motioned her to follow me into my living room, which meant that we had to walk past my bathroom and through my kitchen. Once we were in the living room, I put on my pants and I was putting on my boots, as I told my plan. I told she was to go back into the bed and make noise as I was still fucking her, loud moans and heavy breathing. I would sneak into the service passageway on the other side of my bedroom wall, find the guy, and beat the ...... out him. She began to protest, but I told not to worry about me, as I didn't think it a fair fight unless I was fighting more than one guy at once, and that with my boots, which held steal caps internally, I was lethal. She wasn't worried about me; she didn't want me to beat the guy up, as she thought the scene was sexually thrilling.
I was both disappointed that I wasn't going to kick the ...... out of pervert but thrilled to hear that she thought the situation sexually thrilling. We went back into the bedroom and resumed fucking, loudly. The next day, after she left, I went into the service hallway, where the long narrow hallway was dimly lit by a single 60W bulb. I couldn't see anything, so I returned with a flashlight. I found what I took to be my bedroom wall, which was not insulated; instead, an array of bare two-by-fours, wiring, and piping ran across the wall. I walked to the end of the hallway where my fuse box was located. As I walked back, my nose sniffed something you never forget: the smell you encounter in X-rated video booths at adult bookstores: dried semen. My nose located the most intense spot, and my flashlight revealed a huge splattering of cum on the wall, which had dripped down to the bottom and had blistered the wallboard, wet cum sprayed on dried cum. The smell was intense. Here was the problem, as far as I could tell, that was not where my bedroom was. So, I counted my footsteps back to the door and then I counted the same steps down into my apartment. I was wrong: that was where my bedroom wall was located.
I told my girlfriend what I had found, and she delighted in hearing how huge the cum stain was. She told me that we had to up our game, so the guy would hear a better show. I could only think louder, not better. She explained that I should tell her to suck my cock and to rub my cock across her nipples. In other words, we should describe what we wanted the other to do. I was up for it. Our next sex romp was "better," but we found ourselves getting tongue-tied, so we returned to just moaning.
One night, I was keen to come up with something "better." While she undressed, I told what I loved about her body. I described her entire body. I also revealed what a German tourist had said to me the weekend before, when we had been sightseeing. I had caught him photographing her, her legs in particular. She had worn a flimsy cotton sundress and it was windy, so her short dress blew up to her waist, revealing her entire legs and panties. The German apologized, telling me that her legs the beautiful thing he had seen so far in the USA. I had to agree with him, as her legs were stellar. (She was 5'9", about 122lbs, with high cheekbones and the loveliest red hair I have ever seen. The strands of her hair were multi-colored, some being ruby red, others orange, while other still were a strawberry blonde. Together, in the sunlight, her hair took on an impossible irradiance.)
The morning after a sex-filled night required me to check the spot left on the wall. Sometimes, no new load of semen was deposited, but I lied to her and told her it was huge, as she so enjoyed getting this sort of standing ovation.
