The Room Mate

My wife and I have been happily married for about nine years now. We had never slept with anyone else during our relationship. I have greatly enjoyed my time with her. However a few weeks ago a coworker of my wife’s moved in with us. Her name was Denise and she had just lost her job, car, and about everything she owned in about three days. We were glad to help her out in any way we could. We set up a second bedroom in our modest apartment.
At first things were normal, at least for having another person living with us. Then something happened, something I did not expect. I needed to use the toilet and I heard my wife taking a shower. We only have the one bathroom so I walked in and began to pee. She was very quiet, and usually she bitches at me for doing this, but only in jest. She does it to me all the time, only I don’t flush the toilet. I talked to her like I always do, then when I was done I turned and saw Denise in the shower.
We just stared at each other, me with my cock in hand. And her dripping wet from the shower. Her long dark ebony skin, and straitened black, large breasts with erect nipples, all dripping wet. Then my eyes dropped and I saw her nearly erect ten inch cock that she was stroking. I couldn’t take my eyes of it, I was stunned.

She smirked and said “do you normally walk in on your guests while their taking a shower or am I special.” I tried to say something but couldn’t. “Now you’re just staring at my clit” she said, “my eyes are up here.” I quickly returned my gaze back to her eyes, but still could not talk. “I should be very offended by you walking in on my shower, but perhaps I’ll tell your wife.”
This brought me back to reality. I started to apologies but she interrupted me. “That’s what I’ll do. I’ll go tell your wife you were watching me in the shower.” Then she started to step out of the shower, all the while stroking her cock.
