Holding her underwear made me rock hard, as I breathed them in. It was overwhelming for me, as I had the urge to cum immediately, blowing a rather small load onto my own underwear. The smell of her underwear was kind of sweet and definitely reminded me of her. I put my freshly cum stained underwear next to Mum’s in the basket, before showering and going to bed. Having cum already, I were too tired to go another round, so went to sleep.
Every day was the same when I were around her, staring at her body without getting caught and hoping she’d bring something up about my cum-stained underwear, but nothing. Did she know or didn’t she and if she did, why wasn’t she telling me off, I couldn’t make it any more obvious. Determined not to give up, I continued my filthy habits, hoping that she’d bring it up the next time. The next few nights, however, were different, because now, she’d shower before me, regularly. After cumming with underwear the first time this happened, I ere quite content with this and waited in my room, teasing myself to the thought of her in the shower.
After she finished, I heard the shower go off and the bathroom door open soon after. She called my name.
Mum – “I forgot to get a towel out of the cupboard, can you hand me mine ?”
Me – “Okay, just a second”, I replied.
The door was slightly opened and unfortunately, I couldn’t really see her, but knew she were naked. Walking in on her would be too much, as much as I wanted to, so I waited for her to arrive at the door, before handing her the towel. Due to her short height, she had to put her entire arm through the door opening to reach the towel, as she wanted it quickly, due to being dripping we, having just come out of the shower. As she reached her arm around, I momentarily saw part of her left tit and a hint of nipple, as she reached out far. I instantly became hard and know what I were going to masturbate to tonight, as I returned to my room and waited for her to go to her own.
As soon as I entered the bathroom, I shut the door and immediately searched for her underwear in the basket, breathing it in, as soon as I did and stripped fully naked. I were even hornier than the first time of seeing her underwear and placed it on my cock, grinding it on there. The thought of her almost fully exposed tit was fresh in my mind and sent me over the edge, as I let out a quiet groan, before cumming in her underwear. This was a first and I became slightly worried that it was too far, so I wiped off as much cum off of it, as I could and onto my own underwear, before placing mine on top of hers, in the basket.
After showering I returned to my bedroom and dried off, before getting into bed. I had never seen her bare, breast before and I couldn’t help but get a second boner and had no choice but to cum again. There were no other way I’d tire myself out, to get to sleep.
The next day, was the same old, in terms of behaviour, which frustrated me a little at first, before I started to remember my progress, like masturbating with her underwear and seeing part of her tits. This encouraged me to step up even further and see what else I could get. If all else would fail, I would consider buying a spy camera, which weren’t too expensive.
