Ashley's POV:
I wake up slowly, stretching my arms out luxuriously until I feel the space next to me. Still warm, her indent still prominent in the mattress, and the duvet pulled back up. But no Y/N. I groan slightly as I sit up and rub the sleep out of my eyes, not liking the sudden rush of cold air that I was being exposed to. As I stand up, I feel my stiff legs strain as I stand on my tippy-toes and stretch my entire body, beginning to feel somewhat more awake.
I hear the hammering of water from the shower of the en suite bathroom on the tiles below. I gravitate towards the sound, not completely sure of what I was doing. Someone could be in there. Carefully, I pushed the bathroom door open a little bit so I could look in to see if anybody was in there. Her hand came in contact with the glass wall to steady herself as she bent down to grab her shampoo to wash her hair. Y/N hummed as she scrubbed the shampoo into her hair, turning around as she did so. God, she looked so hot, all her wet muscles, defined as ever, making me groan in lust.
Her dick was poking up, standing to the height of her bellybutton. It really was that big! I could feel myself become almost automatically wet for her. She looked down at it and mumbled "Fucking morning wood", before squeezing some more shampoo into her hand and using it as lube as she began jerking herself off. I stood there shocked but also drawn in, watching as her head fell back slightly, biting down hard on her bottom lip to try cover the moans threatening to come out of her mouth. One of my hands makes its way under my shirt and massaged my right breast. My breathing became heavier, my desire only intensified by her small grunts of desperation. Unable to take this any longer, I stuck my right hand into my shorts, immediately feeling the heat radiating from my core. I slide a single finger through my folds, feeling the wet, sticky liquid on my finger before licking it clean and moaning softly as I continued to watch Y/N's fastening movements. My hand went back down into my shorts, my finger working my clit, speeding up and my hand on my breast squeezing and pulling my nipple harder as Y/N let out small panting grunts, her mouth creating the perfect 'O', as well as mine. After a bit, a loud whine came from my mouth from the stimulation of my hand on my now sensitive clit and Y/N's moans. Her fist clenched up against the glass wall, keeping her supported. "Oh, fuck", a low, guttural moan escaped from her perfect pink lips which sent me over the edge, my left hand shooting down from under my shirt to cover my mouth as I let go over my own fingers. Silent tears fell from my face as my back fell against the wall, my hand dropping to the floor as I just stayed there, panting heavily for a moment or two. Once I'd calmed down, I heard the exasperation of Y/N, exclaiming her pleasure: "Fuck!"
I scurried back to my bed, smiling with the dopamine still flooding my brain. I waited for her to finish her shower, so I pretended to be asleep, waiting for her to wake me up or join me in bed, but instead, as soon as I hear the shower stop, I hear the bedroom door open then shut again, leaving me alone in my thoughts. Why didn't she wake me up or say goodbye? Wait, this isn't right; I have a boyfriend and she is dating Sydney. Shit. What do I do? I mean...it doesn't really mean anything, so...
Y/N's POV:
I left Ash's room feeling embarrassed and like a complete idiot. I can't believe I did that in the room next to her! She's my best friend's sister! I suppose I used to have a small crush on her; our 'fake' flirting, not always being so 'fake' to me. But that is way in the past. Like when I was 8! Not now! What I just did was not right. Why the fuck would I do that in the room next to her? What would've happened if she had seen?
I quickly get ready and changed into an overly baggy forest green coloured suit as I had a Jimmy Fallon interview in the evening. I have a lot of the clothes that I keep here at Jarnette's house, a few from when I still lived here (mostly ice-hockey jerseys that I used to wear to games with David, the girls' father, before he and Jarnette got divorced) and other sets of clothes that I had left here from previous 'sleep-overs'.
