Oh yes she does.

John she screams out while trying to cover herself. "What are you doing in my room, and is, is that your cock hanging out?" she said while covered up. You stand up but not covering your cock up and look at her all red in the face. " Is she mad at you or is that from her masturbating after seeing your cock" you think.

"Well you gonna say anything damn it?" she says while looking between your face and your cock. "Hey there sis, I was, well I was in my room minding my own business and trying to take care of an "itch" when I happen to see your face in my mirror and now you are in here doing the same thing as me. So what is going on?" you say while you stand there naked and smiling. She sits there still red in the face, still looking between your face and your cock when she says "Well I don't know what you are talking about. I was never near your room. I went and grabbed some stuff in the living room and came straight to my room".

You ponder what she says for a few and decided to gamble with her a little. "So you say you was not near my room but yet the camera i have facing my door shows you looking in? So it did not record that?" you say with a big grin. The who time your standing there looking at her and she has kept looking from your face to your cock. Back and forth and it makes you wonder if she likes it.

"Shit, I didn't know you had a camera in your room. Wait, why do you have a camera anyways?" she said. You smile back and say "because of moments like that. So what are we gonna do about it? Should i tell dad about what I found? Plus I keep seeing you eyeing my cock. Do you like it?".
