Siobhan quickly sat up, looking startled. "Wha...," she began, her face taking on a look of embarrassment as she realised there could be no explanation for the way things were, other than having been peeing and masturbating into her pillow the night before.
"I'm...I was...I just.." - it was almost fun to watch her trying to come up with a reason for being naked, with a very obviously pee-soaked pillow between her legs. Her face reddened as she trailed off, and I felt another jolt run through me as I saw her breasts and stomach flush at the same time.
I decided to take charge of things, and try and make her feel as comfortable as I could, given that I'd rather deliberately caught her in the aftermath of having pleasured herself in quite a kinky way.
"Oh hon, don't worry about it! I used to have this happen to me a lot when I was about your age!" I chose my words carefully, making it sound like I was talking about bedwetting, when really I was talking about peeing for pleasure and fucking her pillow.
I took her gown from the hook inside her wardrobe and handed it to her. "You go and have a shower, love, and I'll sort things out in here."
Siobhan stood up and took the robe from me, looking at me with a furrowed brow.
"It's really OK, hon," I said, looking her straight in the eyes, "this used to happen to me, it happens to lots of girls. It's perfectly natural, some people say it's even quite healthy to.." I trailed off. Maybe I'd gone too far there - bedwetting, healthy?
Siobhan gave me a sort of sheepish smirk, and muttering, "Thanks, m," she slunk off to the shower.
As soon as I heard the shower curtain close, I flung my robe open, picked up the wet pillow and jammed it up against my hot cunt.
Almost immediately I just let it all go, feeling the liquid heating and soaking the pillow, my lips, my clit. I felt my hardening clit strain against the material as I pressed it hard into me.
I managed to stem the flow, and started to thrust my hips, rubbing the hot, wet fabric deliciously over my cunt. Before I knew it, I heard the unmistakeable noise of the shower shutting off.
Quickly, I pulled the pillow out from between my legs, wrapped my robe back around me, and ran as quietly as I could to the laundry. My heart was beating like crazy with excitement when I got there!
I stopped for a brief moment to think about the situation. It was utterly depraved, filthy, naughty - disgusting, even - and I was loving every minute of it!
I got the pillow into the machine and started the wash off, then got in the shower myself. Just moments earlier, Siobhan had been here where I stood, cleaning herself of the night's excesses.
The thought of this sent my hand straight to my cunt, fingers rubbing insistently over my engorged clit, the feeling enhanced by the hot water running over my whole body.
I lost myself in the wonderful feelings, and before I knew it, I'd pushed myself over the edge into a lovely, shuddering, knee-trembling orgasm. I heard something in between a grunt and a moan escape my lips - I just couldn't help it!
I leant back heavily against the shower wall, regaining my breath, my fingers still playing gently over my lips and clit.
Suddenly, I heard Siobhan call out, "Bye - I'll see you tonight!" from just on the other side of the bathroom door.
I managed a weak, "Bye, see you when you get home."
God - how loud had I been? Had she heard me? Just the idea that she might have sent a shiver of pleasure through me, and my fingers found my clit again. It was just a quick come this time, but no less intense for that, images of Siobhan watching me masturbate running through my mind.
Luckily, I had a lot to get done that day, so I was able to keep my mind off my clit, pretty much until Siobhan arrived home around seven.
Nothing was said about the morning as we ate dinner together, instead telling each other about the things that had happened as we went about our day.
Siobhan cleared the plates away, calling out, "I'm completely knackered, so I'm off to bed."
I took my chance now, handing her a bottle of water. "Take this to your bedroom with you, OK? I know I liked to drink a lot when I was your age, and I think you'll find it will help with, um, what we sorted out this morning."
I was amazed I could get the words out, I was feeling so horny! I was almost positive that Siobhan would be able to read between the lines. She confirmed this by silently taking the bottle and heading into her room, but not before I could ssee her obviously reddening.
Whether it was embarrassment or horniness (or both), I didn't really mind, as long as she got the message that I was more than OK with her masturbating and peeing in her room as much as she wanted.
Within about five minutes I found myself outside Siobhan's bedroom door. I'd already stepped out of my clothes, leaving them in a pile in the kitchen, so I stood there completely naked. I kept my hands off myself as long as I possibly could, standing right next to the door and listening hard to hear what Siobhan was up to.
It was soon very obvious that she was doing exactly what I'd hoped she would. I could hear a kind of rhythmic movement, accompanied by the rustling of material, and a very faint creaking from the bed in time with it all.
It was no good, I couldn't hold back any longer, and I started to rub my right hand up from my soaking lips to my stiff little clit, my left hand doing its best to play with both my nipples at once.
I was ultra-horny already, but even so, my excitement continued to build. Along with it, I was certain I could hear the movements from Siobhan's room become more vigorous, more urgent.
This in turn spurred me on, and I pressed harder, stroking my middle finger up from my lips, over my clit, and back again, building up a nice steady rhythm as I started to feel that familiar feeling of arousal deep inside me.
I closed my eyes, and imagined bursting in through Siobhan's door, just watching her go at it with he pillow, watching her single-minded focus on bringing herself off, while I do the same, standing beside her, watching.
I got so caught up in the delicious thoughts, and the feelings they bring, that it took me almost a minute to realise that the noises from Siobhan's room had all but stopped. I hoped against all hope that she hadn't finished, that she was watching me through the keyhole as I continued building towards a wonderful orgasm.
I kept the beautiful mind's-eye image of me in Siobhan's room, watching her rubbing her hot cunt over her pillow as I rubbed my hand over my own hot, wet fanny.
What felt like another whole minute went by, and I decided to open my eyes as subtly as possible, to see if I could see what was happening. I leant my head back, opening my right eye just the barest possible amount.
I saw Siobhan's door, and as I watched, the keyhole below the door handle went from dark to light, and I heard a couple of light steps and a sigh from the bed. She WAS watching me! A delicious, naughty shiver ran through my whole body at the thought of this.
I heard the noises begin again in earnest - she was fucking herself again! She saw me fucking myself, and she wasn't disgusted, she went right back to masturbating!
I couldn't believe this was happening - it was like a dream I never wanted to wake up from. My fingers kept at my clit, the index finger joining the middle finger, squeezing my clit deliciously between them as I rubbed over it.
I heard a watery, bubbling sound from inside Siobhan's room - she was drinking the water! This just got better and better...
I decided that then was the time to move right up against the door, and squatting down (with my fingers still doing lovely things to my clit), I put my eye to the keyhole.
Siobhan's bed is to the left of the door, so I had to lean to the right to see it. I only got the slimmest glimpse of her, and only if I held myself in exactly the right way, but what I saw was incredible:
Siobhan was visible from her upper neck to the bottom of her buttocks. I could _just_ see the pillow underneath her bum as it clenched and pushed forward and back. Oh my god, this was utterly incredible, I was finally watching her fuck herself!
