I had gotten a bit shy about nudity but I told her she could. I thought she had to pee or something and it was the only bathroom in the house.She came...in and sat on the closed toilet. She just sat there grinning at me. "What?" I asked. She just grinned harder and slid down to kneel next to the tub. I drifted the washcloth over my lap to hide my stiffening cock."Remember when we used to take baths together?" she asked in a quiet voice. I nodded. She was still grinning as she reached down into. . put those back on.” She teased and I looked at her and she was looking at my legs. I paid little attention to her comment and told her to shut up that this was my house anyways and I could walk around like that if I wanted to. I kept watching the movie and put my PJ’s on not caring a bit. I really didn’t mind wearing just boxers in front of her; heck I really don’t mind wearing boxers in front of anyone, it’s just like wearing shorts so I really don’t mind.But now this is where things get. Tammy gave my hard cock a gentle stroke, and she was smiling at me when my eyes opened. I gave the real clock a quick glance as I took another deep breath to wake up."Good morning," I offered with a smile. "My internal clock is at least six hours ahead of that one." Good morning, Professor," she said in return. "We should have tried harder to stay up later last night. I got the best eight hours of sleep that I've had in months, thanks to you." She gave me a naughty grin as she stroked my cock. I soaped up and rubbed myself, feeling the urge rise higher as I run my fingers between my legs and crotch, that was when he walked in, I guess he had been watching me, maybe having a sly wank, when he saw me do something similar, rubbing my pussy and clitoris, 'Does it feel nice doing that', I looked up and said 'Yes'.I kept moving my fingers between my vaginal lips, 'Do you like watching me', and I parted my labia to expose my erect clitoris and fingered it as he watched.Come closer I urged.
