Mum started to become a bit more inconsistent with her shower routine, sometimes going before me and sometimes after, so I wouldn’t know whether or not I’d cum in her underwear or not, but hoped every time, that I could at least do that. I also hoped that she’d go to the bathroom after the shower again, just so she may see a cum stained underwear. My hope was that she’d be more horny at night and potentially like what she’d see, if she’d see it.
Another ‘shower night’ arrived, but she went after I have already been. As soon as I heard the door shut, I looked into the cupboard outside the bathroom, in the hopes that her towel was still there, which it was. This gave me a little bit of hope, as maybe she’d ask for it again and I’d see something. I anxiously waited for her to finish, instead of sleeping, like I normally would, but I didn’t hear her call me. My bedroom door was left slightly open, enough so I had a decent view of the cupboard. Finally, I heard the bathroom door open, after waiting for at least 10 minutes.
Due to her towel being in the cupboard outside the bathroom, the chances are, she’d be naked, something I had only thought of, when I heard the door open, so I anxiously waited to see if she’d make her ways towards the towel cupboard, which she did. I didn’t see much of her breasts, because I only got a side view of her and her arm almost entirely blocked it. I continued looking however, as she turned her back towards me and squatted down near the cupboard, as I locked eyes on her
fully exposed, bare, rounded ass, for the few seconds I could, before she grabbed her towel, covered up and made her way towards her room.
Having showered already, I had a lot of drink earlier, so I needed the toilet and quickly went. There’s no way I wasn’t going to masturbate over that. I may have been tired earlier, but I wasn’t now. As I went to the sink to wash my hands, I noticed her underwear in the basket and thought to myself. Why not ? After all, it had been a while and after seeing her bare ass, I want to cum as hard as I could.
I took the underwear straight to my room, laid naked on the floor and teased my cock until I blasted a load all over it. That wasn’t enough though, so despite not being horny straight after cumming, I continued to tease my cock, making myself hard again and again, until I let out two more loads and in her underwear, all whilst fantasizing about her bare ass I’d seen for the first time, smearing it all over until it was almost entirely soaked, before putting it back in the basket. My sister would always get up before my Mum in the morning and I didn’t want her to see it, so I hid it under Mum’s clothes, in the basket. Her underwear was black, unlike the lighter coloured ones she’d worn on most other night, so if she happened not to see any stains all the other times, she’d have to now.
Same afternoon after work, the next day and nothing new from her again, despite the clothes being in the basket downstairs, as she’d normally bring them downstairs. Her underwear wasn’t completely visible, but it was still visible enough to see at first glance. I ate, before I went to my room and on the PlayStation, trying to distract myself from sexual frustration of her silence. The image of her bare ass was still in mind, whenever I thought about her and I did so a lot. After playing for a few hours, I went back downstairs to eat and then to shower. She said I could go before her today.
