After a long day I'm looking forward to a relaxing evening. Deciding to take a show I get undress and feel the warm water melt the stress away. I run my hands over my body reaching my breast I happy gravity has left my C-cups alone so far. Rubbing my nipples ever so slightly. I start thinking about how long it has been since I've had a man, any man. As my mind continues to wonder my hand reaches down between my legs. Across my smooth pussy. As I start to relax I slide a finger in my pussy and play for just a moment.
Suddenly the bathroom door opens and my son step in. "Sorry Mom" he says "I just need to pee quick" as he walks in. Before I can respond he has his dick out the stream of pee flowing.
Pulling my hand away I'm shocked and horrified by this, but yet I cannot look away. He stands there shirtless with only a pair of sweatpants on. I would not say he is a jock or anything but he does play basketball with his friends a few times a week.
Feeling guilty I then look at his dick. As I start to start at his dick I start thinking he is not my little boy any more but a young man. I find my hand reaching almost on its own for my pussy. As I'm about to speak he finishes up he flushes sending a blast of cold water in the shower and heads for the door. The chill runs through me, turning my nipples rock hard, but my lust does not fade.
As the show warms back up I think how could I be turned on he is my son. But then he is 18 the dirty part of my mind chimes in. Again I try to shake the dirty thoughts away to no effect. When I get an idea, he is my son and he did a bad thing. So any Mother would understand he needs to be punished. If punishing him gave me some pleasure so what. As long as things do not go too far it is ok I justify to myself.
Stepping out of the shower I dry off and slip on my robe and head for his room. Planning out how I can punish him and have just a little fun. As I walk over to his bedroom door I notice it is slightly open. I peek in and see that he is talking to one of his friends on his phone, telling them that he just saw me naked in the shower.
That bastard I think he did all this on purpose just to see me naked. My plans forgotten I'm ready to just yell and scream at him. But then that dirty part of my mind chimes in again. Wait just a minute, this makes this even better. He wants you, go for it get your thrill. As I go back into thinking about this should I do it, or should I just walk away. I listen to his side of the conversation.
"I total did it." I hear him say "I just walked in the bathroom while she was in the shower."
"Well I peed." he responds to a question from his friend. It sounded like his friend did not believe him from the exchange. "I totally did it...I did...I so did it...well fine if you don't want to believe me then screw you." He hangs up the phone, obviously frustrated that he friend did not believe him. Again my dirty mind starts to think, see his friend doesn't even believe he would walk in on you in the shower, no one will know. Still watching through the crack in the door I see him lay back on the bed and pull his dick out of his sweats.
He slowly start to stroke it, I quietly watch from the door my eyes growing big as I look at my son's hard cock, wondering if I should cross this line. Lost in thought I hear him moan "ohhhh Mom that feels so good." Realizing that he is thinking about me as he strokes his cock makes up my mind. He is a horney young man, I can go in there and have some fun.
My mind made up I knock on the door. Still watching I see him quickly pack his hard dick back in your pants. I can't help but smile seeing my son trying to stuff his hard dick away. If he only knew that I was watching, that I have plans. "Ok come in." I hear, pulling me back to reality.
While no turning back now I think to myself as I open the door. I stand in the door my silk robe clinging to my body and say "You know you should not just walk in on me when I'm in the shower."
"I know, sorry Mom" he respond, trying to hide the bulge in his pants. All the time look at me storing away the mental image for when I leave.
"I don't think sorry is enough this time." I say, trying to hide my excitement at the dirty thoughts I have planned "You need to be punished." Saying that I sit down on the bed next to him. "Lay across my lap," I tell him.
"What?" he says shocked at my request.
"I said bend over my lap." giving him my best stern mom stare. "You were a bad boy and need to be punished. So I'm going to give you a spanking."
