[Author's Note: This story is essentially a "deleted scene" I chose not to release originally. I felt that it served only to distract from the real storyline between Mark and his sister Jen. It does, however, make for an interesting situation, provided the overall context of the other chapters of this series. Just keep in mind that this is just for fun and that I recognize that it doesn't really fit in with the other chapters. The events in this "deleted scene" take place between chapters five and six.]
"Mark, could you hand me the next tile?" asked my father.
We were busily working on our hands and knees to finish putting down a new floor in our parent's bathroom.
"Sure...here you go." I said, handing him the next one in the pattern.
I was surprised. Things between my dad and I were just fine. I was expecting today to be really awkward.
Only yesterday, something had happened that I figured he would be upset about. If anything, he and I were getting along even better. The bathroom would soon be done, and he and I had bonded a lot by doing it ourselves, even with what I did yesterday.
My parents have a bathroom attached to the master bedroom, which they use, leaving the upstairs bathroom for my sister, Jen, and I to use. Well, my parents decided to finally use some of their savings on renovating their bathroom by putting in a tub surround, new tile on the floor, light fixtures and fresh paint. They used our bathroom for the two weeks it took for my Dad and I to get the work done.
Last evening after I got home from work, I went up to my room and took all my work clothes off so I could go take a shower. I heard that the shower was on and heard Jen singing in the bathroom. I smiled to myself and quietly opened the door and shut it behind me without making a sound.
Jen and I had mutually agreed that we could use the bathroom together, and had recently begun to develop our bond as brother and sister by becoming more intimate with each other. We were letting ourselves be naked together once in a while, and things had escalated from me accidentally ejaculating on her to actually having anal sex. A month ago I had given her oral sex for the first time during a trip we were on.
We still had not had what I would call "real" sex yet. It wasn't like we had agreed not to, but we just hadn't become that intimate. I'd entered her once, by accident, but it was quick, and she still teased me about it. Even so, we were enjoying becoming closer. Neither of us was perfect, and we'd still have our disagreements, but we worked through them because we trusted each other and really loved each other.
So that evening, I was excited to join her in the shower and to see where it might lead. She had the main lights off and was just showering with the light of the ventilation fan. The dim light cast a silhouette of her shapely body on the shower curtain. I stood there watching and listening; just enjoying her.
Finally, I cleared my throat. The singing stopped.
"Hey, it's me. I'm coming in. I'm turning the light off." I said. I flicked off the switch and cautiously slipped around the shower curtain and into the shower with Jen in the dark.
Breathing deeply of the scented steam, I raised my hand out until I came into contact with her warm, wet flesh. She was facing the water, so I stepped forward and pressed my naked body against her back. The water was splashing on her shoulders and running down her back as I pressed my penis up between her butt cheeks.
