"How about these?" Bee held up the tiny lace knickers she had worn the first day we met. It was now four days later and she was searching for a pair of knickers for me to wear out tonight.
"Aren't they-"
"Yup."
"I'm not sure that they would keep everything in Bee. They are quite tiny. Why can't I just wear some of my own?"
"Because the point is that we are dressing up as each other. These ones will be fine," and with that she thrust the knickers into my hand along with the matching bra. Next she handed me a black skirt and one of what seemed to be an inexhaustible supply of black and yellow striped jumpers. "This one is a bit big for me so it should be ok for you. We'll do your hair once your dressed."
I made my way back to my room, undressed and delayed getting dressed again by stopping at my sink to shave. Freshers week was now in full swing and had been something of a social whirl. It had mainly comprised of sleepy mornings, afternoons full of administrative tedium and nights of drinking and making new friends. My flatmates were all friendly and for now we were all getting along well. Bee and I had stolen some precious moments together but we could not be described as a couple, 'good friends' was probably more fitting. Tonight was Wednesday night and Wednesday night of freshers week was drag night at the student union. Boys dressing up as girls, girls dressing up as boys. Bee had hit upon the idea of the two of us simply swapping clothes, a convenient idea that meant she could still wear girl's knickers.
I finished shaving and started to dress again. I stepped into the knickers and pulled them up. They were too small for me and there was limited room for my penis which proceeded to flop out whichever way I tried to position it. Next I picked up her bra and, before putting it on, had a quick peek at the label. 34C. Bra sizes have always turned me on, just the sound of them. 34C, 32B, 36D, whatever. They just sound sexy. I fastened the bra around my chest and padded it out with a few rolled up socks. I quickly pulled the jumper on over the top to save my embarassment. The skirt was actually quite comfortable and I was pleased with the overall effect despite the discomfort of my crotch.
I made my way back through to Bee's room and found her pulling my pair of brown cords up her legs and fastening them with my belt. She wore my blue jumper and had dotted her face with stubble using eyeliner. Unable to do anything to replicate my much shorter hair she had simply covered hers up with a woolly hat taken from my room. The effect was oddly disorientating.
"Hello Thomas," I greeted her.
"Hi Bee," she replied. "Look, I'm not wearing a bra," and she thrust her chest out, making it impossible for me to miss the bulge of her shapely breasts.
"Well, I wouldn't expect you to wear a bra," I said, trying to stay in character.
She giggled and pressed herself up against me. She ran one flat palm over the front of my skirt, awakening my soft penis. "How are the knickers?"
"Tight."
"You've got good boobs," she cupped my sock-padded tits. "You've done them a bit big to be me though," she smiled.
"Nah," I insisted and slid one hand up her jumper to cup her boob, causing her to purr with pleasure, "I think I got them just right."
She removed my hand from her chest and told me to sit down at her desk. I did as I was told and she began to decorate my hair with yellow and black clips and bobbles, pulling bits of hair this way and that. Next she slipped assorted bracelets up my wrists and painted my nails. We argued about make-up before hitting the compromise that I would wear eyeliner and mascara but that was all. She applied it enthusiastically.
Our flatmates had congregated in the kitchen and as we strode in, Bee looking like me and me looking like Bee, they broke into a spontaneous round of applause. We got drinks and joined the party, the girls all comparing their applied stubble, us boys predictably comparing our fake chests. Soon we decided that we should move down to join the party at the student's union and finished our drinks in preparation. However, as we moved off down the corridor I realised that Bee was missing and assumed that she had gone to the toilet. I told the rest of the group that I would wait for her and as I waited on my own in the corridor I paced up and down practicing swinging my hips whilst I walked and pushing my sock-boobs out in front of me. When Bee didn't reappear for five minutes I began to worry. I checked the bathroom but she wasn't there and so I knocked on her door but there was no answer there either. Realising my phone was in my room I went there and was surprised as I opened the door to find Bee in my room, looking like me and standing at my wardrobe.
"Oh. What are you doing here?" I enquired, a little confused and a little annoyed.
"I don't feel like going to the student union," she replied. "I feel like staying here."
"Oh."
"You look sexy."
"I look like you."
She giggled. "Lets play a game."
"O-kay," I replied hesitantly.
"Well, not so much a game, more of a re-enactment."
"Ok. What do you want to re-enact?" Now I was completely confused.
"I want us to re-enact what happened the first day we met."
My head whirred with the implications. She wanted us, me dressed up as her, her dressed up as me, to re-enact us having sex. I still didn't understand how this would work entirely but the more I thought about it the more I liked it and my cock, one step ahead of me, was already growing hard in anticipation.
"Do I have to be all nervous and stuff?" I asked.
"No, I have to be all nervous and stuff. You get to be a purring sex kitten," she said with a wink.
"Well, I can certainly do that. So, what happens first?"
"You don't remember? You come into my room all sexy looking and find me packing away my clothes and I try to hide the fact I'm staring at your boobs and hold myself back from jumping your bones straight away."
I backed out of my room and knocked on the door. I heard Bee shout to come in and entered. I sat down on my bed, my hands behind me and pushed my chest out for effect. Bee pretended to look all flustered and made a show of staring straight at my chest.
"C-come and s-s-sit down," she stammered.
"Hey, I wasn't like-" I started but she held up a hand and glared at me. "Ok... um... you can call me Bee if you want," I made an attempt at fluttering my eyelashes towards her. "Um... something about me being dressed like a bee."
"It's not weird at all, you seem like an ace person," Bee said with a smile. "Anyway, maybe I've got my own secret."
"Like what?" I asked.
"I- I like to wear girl's knickers," the sentence sounded unreal coming from her mouth.
"Can I see?" I tried my best at a coquettish purr.
With that she pulled down her trousers and I was left staring at her wearing my knickers which, suffice to say, looked far far better on her. My cock was definitely getting much harder now and was forming a tent shape in my skirt. I did nothing but gaze with admiration at her legs, her hips and the black lace that was obscuring her pussy. The very same garment at which she had gazed at in astonishment just days before.
"I can't believe you're wearing girl's knickers," I told her.
"I don't wear them all the time."
"They're nice. I think I've got some quite similar." I did have some like that, she was wearing them right now. This game was confusing but I wasn't complaining. "Um, what comes next?"
"I blush a bit and you offer to show me your knickers."
"Oh, right. Do you want to see my knickers?"
"Mmm, yes please," she replied. She was much better at being me than I was.
I stood up, my hard-on already obvious through my skirt. Trying to ignore this I unzipped the skirt and let it fall to the floor, leaving me standing in a pair of too-small knickers from which my hard cock had already burst free. It did not even keep my balls in and so was essentially just decoration but Bee still grinned approvingly. Now I pulled the jumper up and over my head revealing a black lacy bra stuffed with socks. A naughty smile crept across Bee's face before she realised instead that she was supposed to be gawping at my breasts.
"Mmm, nice," she said, forgetting to look at my chest and instead staring straight at my erect penis. I took the compliment.
She took a step towards me and grabbed a handful of my butt cheeks, feeling the material stretched over them. The head of my cock was already pushing against the top of her thigh. Bee knelt down and proceeded to run her finger along the embroidery on the front of the knickers, looking up at me as she did this. She knew full well that I would much rather she stroked my cock instead but she was clearly keen on sticking to the script. Her fingers explored further down and I felt her fingertips brush across my testicles and further down between my legs.
"Take them off," I could hardly get the words out.
"Sure?"
"Yes."
