Getting ready for work

After a while Susan switched back to her own body and headed into the bathroom to shower. I watched her ass sway as she left the room and was amazed to find that Steve's cock was already rising to the occasion again. My brother-in-law must have gotten all of the libido in that family's DNA.

I lay there for a few minutes considering whether or not I wanted the jerk one out, but when I heard the water in the shower start, I had a different idea. As quietly as possible I climbed out of bed and crept across the room. The shower stall had yet to fog up and I got there just in time to see Susan washing her ass.

I smiled to myself as I crossed the room and pulled the stall door open.

"Hey sis, room for one more?"

Susan turned to look at me, a slightly annoyed expression on her face. It was the look In normally got if I tried to join her in the shower. Then her eyes dropped down to her brother's hard cock and she bit her lip. After a moment's hesitation she smiled.

"Sure, Steve, come on in," she said.

I stepped into the stall, turning to close the door. When I turned back around she met me with a passionate kiss. I pulled her close and we made out under the flow of hot water for several minutes, my cock pressing against her pussy.
