I'm a 24 year old woman and I'm currently in a relationship with a 40 year old guy. He's hot, intelligent, funny and great in bed. He also has a teenage son (15) that lives with him.

I get on with his son fine, we hang out, watch movies, go shopping etc. I've caught him checking me out a few times (looking at my ass when I bend over, looking down my top, staring at me when I was in a bikini etc). I've never said anything because, well he's a teenage boy, what do you expect!

Anyway, a couple months ago I was home alone, just had a shower and was finishing up my after shower moisturizing when the bedroom door opened and in he walks. He'd thought it was his dad who was home.

So there I am, completely naked, skin glistening slightly from the cream, one foot on the bed, facing him. He stands there dumbfounded, eyes trailing up and down my body, taking everything in. I left him for about 30 seconds before clearing my throat gently. His eyes snapped to mine, his face flushed red and he bolted from the room and out the house.

I think he expected to get in trouble later, but I never told his dad and when we were alone and told him it was OK, honest mistake, but perhaps he should knock from now on.

Then two weeks ago, in the middle of the night, I got up to pee. When I was washing my hands the tap gushed out water and soaked my nightie. So i slipped out of it, dumped it in the hamper and went to leave the bathroom, intending to get a dry nightie before going back to bed.

I opened the bathroom door and there he his, reaching for the handle, in just his shorts. He stands there, once more staring at my naked body. This time I can see his cock starting to rise inside his shorts. I cough gently again and he just steps aside this time.

I just smiled to myself and walked past, his eyes on me as I walk away, knowing he was staring at my ass the whole way. Took him a while to finish in the bathroom, so I wonder. Did his hard on delay his pee, or did he had a wank?

Well this brings me to the other day. In the house, needing to check something online, my tablet wouldn't connect so I nipped upstairs to the son's bedroom, to use his PC.

Now when I first started seeing his dad I promised I wouldn't go in his room. That was for him and his dad. I'm not his mother, so I don't have any right to invade his privacy. But I figured if he didn't know, and it was just to check the internet....

I load up his PC, while taking a look around the room. Before I opened the net, I spot a folder on the desktop. The name is just 2 letters, which also happened to be my initials. I can see from the preview icon it's got photos in it.

Curious, I opened it. The photos were from a camera phone and were all of me. Photos of me sunbathing, sitting around the house, working in the kitchen, garden etc. Couple of down blouse shots, some close ups of my ass etc. Was also a couple of word documents. They were stories. Based on the after shower incident and the nighttime bathroom encounter. Stories that started off in fact, then went off into very detailed and very erotic fiction. They were actually pretty good.

So now I know he's got a crush on me, is photographing me when I'm not looking and writing erotic fantasy fiction about us. But I'm not supposed to know and can't admit I do, without revealing I broke my promise about his bedroom.

Any suggestions what I can? I love his dad and hope we'll be together for sometime to come, but do I want my boyfriend's son fixating on me?
