Katy and I remained close, even though I was dating her best friend. Heather knew she had always been my crush and would often tease me about it. Reminding me that not everyone gets to be intimate with their crush, least of all fuck them in the ass!
Knowing now what I do about Heather and Becky seeing each other in their bi-curious relationship and me on the side, I often wondered just what kind of relationship me and Heather had, I had to be real and understand that I had been shared, quite freely amongst her friends, then there was the twins, whom I'd been balls deep inside as the sister watched.
It was only when Katy introduced me to one of her other friends studying Art, that I was exposed to girls outside Heathers friend group. I soon met Beth, who wasn't unsimilar to Katy, save the fact that Beth appeared to have a push up bra on with obviously smaller boobs that she wanted to be bigger. That said, like Katy, she was well proportioned and her slender height and mousey long hair helped her pull off an elegant artist's look.
"I'm not normally this forward with boys." Beth told me, biting her bottom lip, "but something about the way Katy spoke about you, made me wanna meet you, I've been looking for a life studies model for my Art coursework and she suggested you'd be perfect for it!"
The task was simple, I was to pose for Beth's artwork. I could do that, no problems, I wasn't in class on the days she was so it worked out well. I turned up to her class every week for 4 weeks as she worked on this term's work. I'd stand in silence, shirtless with the others in class, Her sat opposite ensuring she got the best possible use of the time. Sketching and doodling various positions to build her portfolio.
"Listen Dave, I hope you don't mind but I'd like to meet up at the weekend to get more done on this if you're up for it?" Beth asked with an almost desperate look in her eyes.
"Of Course, whatever you need!" I instinctively replied, making sure she knew I was only too happy to help.
"Whatever I need huh?" she said cheekily.
"Excellent, I'll hold you to that! shall we call it 10am at mine on Saturday?" She continued.
I nodded in agreement, smiling. Saturday was always ok for me, it was boring and if nothing else, I knew I was going to spend it with Beth - who was, to be fair, pretty hot and fun to be around. Sunday arrived and I found myself once again going to a girls house on a weekend to 'help' her with her school work, however, she did definitely need to get this work done and I was the means to that end.
I wore simple clothes as usual, jeans and a t-shirt with some tight boxers, knocking on her door. Beth answered with a wide smile wearing a plush white bathrobe, I smiled and thought nothing of it, it was a sunday morning after all! "Hi, please come in and make yourself at home!" She encouraged me.
She took me through her house to the living room, I could hear music coming from upstairs from what I assumed to be her bedroom, becoming obvious we'd be there alone. In the living room was a neatly presented open space for me to stand, a chair to one side for her to sit and a chair to the other side for me if I needed too as in class.
"Drink?" she asked, moving to her kitchen adjacent. I nodded as she continued from the next room "Thanks for coming over. This project is becoming a nightmare, they want more and more drawings and angles from me.. It's crazy!"
I listened as I sat on the sofa briefly, looking around at the walls, photo's and decor of her house.
"I er, have a request though"
"Go on, what do you need?" I answered.
"Would you mind posing in a swimsuit? So I can get more body tone? They've advised that I try it for a better mark."
I paused, smirked and replied "I mean, sure, of course, but I er, didn't know so I didn't bring one!"
Her word usage was curious, she could have asked me to pose in my undies or even nude and I would probably have been up for it.
Beth poked her head around the kitchen door and gave me a grin "oh it's ok... I hope you don't mind, but I took the liberty to pick one up for you!"
I was a little taken back by this, it was only Heather who had ever bought me something to wear, and given my problem, fitting in things; I was a little worried that she may not have realised what she'd potentially done. Her voice shouted out from the next room again. "There's a white bag on the chair, it's for you!" as she walked back in with a coke for me, handing me the drink before I could open the bag, for some reason, asking me this not being face to face seemed to be better for her, I was slowly building up an idea that Beth was an oddity, she was confident enough to ask me to pose for her artwork but seemed more modest when it came to being direct with me as a guy it seemed.
Beth moved to the window and pulled the curtains across ensuring privacy, Then made her way to the stairs adding "I'll go get my work and leave you to get changed. Are you ok doing it here or do you want more privacy?"
I shrugged and smirked "well, you'll see me almost naked soon for a few hours anyway! So I'll be ok here thanks."
Beth gave a wry grin and vanished upstairs. I pulled the bag open and saw a box, opening the box I immediately saw it was a black thong. It was the first time I actually felt self conscious about a situation like this since I first lost my virginity. I blushed and panicked, it simply did not look comfortable - or able to contain me, so small and thin, after a moment, I managed to get my thoughts back on track telling myself "you did say, anything!" and started to strip, piling my clothes up neatly and sliding my boxers off, just the thought of Beth seeing me in this was making me impossibly thick, I stepped into them, pulling them up and onto me cheating a big smooth bulge, tucking my thick length in as much as I could. The thin fabric surprised me, it filled and stretched outlining my thickness and cockhead at the end. The high hipped stretchy material and thong back rode way up my ass, it was weird, I felt a mixture of sexy and completely exposed: more than being naked ever did. It was amazingly more comfortable than I thought it would be, my first time in a thong and it felt so different - I was a little worried that thongs on men were gay? But I admit, I had no idea really.
It didn't feel like a swimsuit either, at least, I got the impression if it ever got wet it'd cling to me and provide no support at all - it was more like a stripper's thong.
Within no time at all Beth returned from her bedroom, the music still going up there to no one but lazily left on to provide a little background noise. Her art pad in her hand, she stood still in the doorway, looking me up and down, she gasped and bit her lip, blushing a little as she did.
"Oh my god!" was all she could gasp with a mix of giggle and surprise.
I looked at her and in a self conscious way cupped my large bulge so as to hide it, sheepish for the first time that year in front of a girl since Katy caught me with my cock in hand at the water park. Beth giggled at my body language and continued to move into the room.
"It's ok, you can relax Dave, how does it feel? I hope I got the size right?" she asked.
I smiled and slowly moved my hands away, this wasn't too bad, right? I thought, considering what I'd done in the last few months. I nodded my head in agreement and twisted my body so as to look at my behind,
"Give me a twirl then?" she asked as she sat down in her seat, opening her portfolio up and getting out her pencils.
I started to relax as I spun in the middle of her living room, Beth giggled and gave a cheer "wooo! It's like having a stripper!" We both laughed as I stopped and stood in a similar pose to how I did in class.
"I really do appreciate you doing this Dave, getting muscular details and form will get me a much better mark." Beth told me as she prepped her page.
I gave her a reassuring smile and stood there as I had been, "I told you, anything you need!" with a cheeky wink.
"Thank you! Just let your arms drop by your side and turn slightly... there. Perfect!" Beth smiled.
"mmmmmmm!..." Beth sighed almost silently.
I turned my head towards her, instinctively,
I'd been standing for about 20 minutes silently as I had done in class. I would see her eyes glance me up and down, then back to her work. I was actually impressed with her drive to do actual art and commit to the piece she'd started.
