She was cute, helped no doubt by the fact that she was naked, desperately clutching her panties as she waited for the bathroom. She stood awkwardly, using her right arm to cover her nipples as her legs twisted together and her left hand lazily hanging in front of her hairless pussy. I flashed her a smile which she returned with a slight shrug as she glanced down my body reminding me that I was also naked. I was making no effort to cover myself, my flaccid penis hung lazily between my legs against my balls obscured by my pubes. As her eyes reached my penis I moved my hand to cover myself; she looked up and smiled at me again.
"How is the ass?" she mouthed with a smile.
"Ouch," I mouthed back, "yours?"
She just smiled and shifted her weight uncomfortably as Donna came out of the bathroom and smiled at us as Alan went into the bathroom. She was wearing a vest top and panties set which further highlighted my feeling of exposure as I stood in there room naked. Alan didn't take long, and as he came out Fi headed in, only to be stopped by Donna. "You go first," she said looking at me.
"Bitch," Fi said in a tone that implied a playful humor, but had an underlying indication of anger.
I just looked at her confused as she stepped to the side to let me go first, "Why?"
"Because..." she began before being interrupted by Donna.
"Because your sweet innocent sister has cum dribbling out of her ass and I am enjoying watching her trying desperately to not further embarrass herself," Donna said grinning.
I just looked at Fi who shrugged, her hand still lazily covering her pussy, but her breasts exposed. My eyes were naturally drawn to them as I edged past her and into the bathroom. I cleaned up the lube that was starting to dry, but was as quick as possible. Girls are evil, I thought to myself, maybe evil is a bit strong, cruel maybe. Donna had already knowingly allowed Fi to take a load up the back door and still she was drawing out her opponent's humiliation as long as possible.
When I got out of the bathroom Fi was stood on the balcony as Donna teased her. Fi just took it, not rising to the bait, silently standing on a balcony with nothing on obediently lifting her arms and turning around as and when instructed by Donna. Donna was sat on the bed casually spinning Fi's panties on the end of her finger using the waist band of them. She watched, but only to make sure she was doing as she was told. Fi saw me come out and quickly passed me into the bathroom to clean up, only taking a few minutes; she didn't have anything to get dressed into after all.
Donna continued to play with the panties that she was holding, dangling them on the end of her finger, almost like she was showing Fi exactly what she wasn't wearing. What struck me is how small they were, just a small piece of black material, physically tiny, but losing them was symbolically huge. "You going back to your room then?" Donna asked.
"Naked?!" I exclaimed.
"That was the bet," she replied smiling at me.
I was about to protest, but Fi spoke first, "Fair is fair," she said.
I just looked at her, it was almost 6 am, cleaners would be about at least, and we were about to run 3 floors naked? She just smiled at me with her "Yeah, I know" expression. She knew, and I knew there was no way we were ducking out of this one. Alan handed us our room key and opened the door. We peaked out into the corridor, which was clear, although the auto lights were on so someone has been about within the last 5 minutes. We looked at each other and stepped out into the corridor. "Good luck, see you later," Donna said as the door clicked shut behind us.
We headed down the brightly lit corridor; I could feel my heart pounding as I tip toed down towards the stairs. "Lift or stairs?" I asked.
"Stairs," Fi said. "We can run if anyone is about, lift we are just displayed."
"OK," I replied, somewhat surprised by her clarity of reasoning, but went with it.
She swiped the key card and fell into the room as I pushed her inside and slammed the door louder than I meant to as the adrenaline coursed around my system. "Wow," Fi said, "that could have gone better."
"Yeah," I agreed as Fi put one of the dressing gowns on, "What did he see?"
"Well... a 20 year old naked girl sprinting upstairs followed by her naked brother..." she said smiling.
"Yeah, silly question," I acknowledged, "sorry."
"It's okay" she replied, "the rest were female cleaners, they weren't looking at me."
"How many?" I asked smiling; I had never streaked before, but it really was quite exciting.
"Six or so?" she suggested looking at me, to which I just shrugged. I wasn't counting.
"Oops," I replied shrugging. "How is your..." I began before stopping myself.
"Feels like it has been fucked by an average sized cock," she replied, guessing my question.
"Sorry," I said looking concerned.
"Can't believe you fucking came," she said grinning it me.
"Yeah, sorry," I repeated.
"It's fine," she said hearing my genuine apology. "I did too... can't believe he made me cum with his dick up my ass."
"You were... you know though," I said looking at her, "playing..."
"I still came with a cock up my ass though," she replied smiling at me.
I just smiled at her. "Bed time for a few hours?" I asked.
"Yeah, defo," she replied. "You sleeping naked again?"
"Yeah if you don't mind," I replied.
"Fine by me," she said.
"You?" I asked.
"No, will wear panties," she said, "Will probably be farting cum all night."
"Oh, that is wrong," I said screwing my nose up, not believing she just admitted to that.
She just smiled as she grabbed a clean pair of panties and headed into the bathroom. She came back after a few minutes only wearing panties. I smiled at her as she wandered around the room sorting out her clothes and stuff. Her breasts gently rippled with the shock of each footstep, her mint green panties hugging between her legs as she wandered around in front of me half naked.
I got up and went into the bathroom, I did my teeth and considered having a shower, but it was way too early, or late whichever way you looked at it. When I was finished, Fi was already asleep. I climbed in next to her being careful not to wake her and quickly fell asleep.
