You wake up indoors, and quickly realize you are in the lifeguard's locker room. You also immediately notice that you are being held by a piece of tape across your stomach to a mirror on the inside of a locker door. There are a few hot girls walking around and undressing nearby, and you are staring at once particularly busty girl who is struggling to fit a tiny red bikini over her massive breasts. They keep jiggling as she tries to tie the straps behind her back. You must have been staring for a good five minutes before you hear an "Ahem." right above you. You jump, and look up to see Juli, smiling down at you. Juli has taken off her small white shirt, and is only wearing her tiny, red sling bikini. You ask, "What happened? Why am I taped up here?" Juli smirks coyly, and says, "Well, after our little fun, I came in here to see if I could fix my bathing suit problem. Maybe I could stretch it out or something. Anyway, you were asleep and I didn't want to wake you, so I brought you with me even though it's a women's only locker room. I left you on the bench at first but one girl almost crushed you, so I taped you up to my locker door just so you wouldn't get sat on!" You thanked her for thinking so carefully about you, but you didn't say how glad you were that she had taped you right at chest level, giving you a perfect view of Juli's breasts as she talked.
Now that she was only wearing her tiny bikini, you noticed that she wasn't kidding when she said it was small. Each of her breasts had a vertical strip of tiny cloth stretched over them which ran from her crotch to her shoulders and then back down to her ass. One of her nipples was poking past the fabric and one was being squished down by it. The red strands of the sling were eaten by her pussy. Your mouth hung open at the sight of Juli’s practically naked body. Juli caught you staring and said, "Jim, please! Just because you're in the women's locker room doesn't mean you can stare like a wild animal." You blushed and started to apologize, when Juli giggled, "Oh, I'm kidding. I just gave you a blowjob after crushing you beneath my cooch, there aren't not many secrets between us anymore. Feel free to look all you want, just don't drool on yourself, heehee!" You closed your mouth, which had been wide open. Juli said, "Now just sit tight, I want to see if I can get this stupid suit to actually cover up some skin..." You joked, "Why? I think it fits perfectly!" Juli smirked and pretended to glare at you, and said, "Don't make me use YOU as a suit!" and you both laughed.
Juli looked into the full length mirror you were stuck on, and started to adjust her bikini. She pinched the sides of the fabric above her nipple and pulled, stretching it very slightly, before releasing it. Every time she did this, she jiggled her boobs around for a few seconds, almost managing to cover her entire areola, before the fabric shrunk back to its normal shape, and her breasts were exposed again. After a few minutes of fruitlessly trying to enlarge her suit, she leaned forward and started carefully pulling at her right bikini strap. As she leaned forward, her massive left breast came down right in front of you. It hung inches from your face, and occasionally bounced as Juli fiddled with her bikini. Her tiny bikini didn't even cover her nipple, which had pushed the fabric aside and stuck out straight ahead, towards you. You were just staring at it, slack jawed, as Juli moved a little closer to the mirror to get a good look at what she was doing to her bikini. Her nipple lightly brushed against your chest, and you reached out to it. You began to fondle Juli's huge nipple, and rub her areola. Juli looked over to see you fondling her. She giggled, and said, "Don't stop, Jim. That feels amazing." You happily obliged by squeezing her flesh as she went back to pulling at her right bikini strap.
You were having the time of your life when Juli leaned forward just a bit too much, and her huge boob slammed into you. You heard Juli grunting as she tried to force her bikini to widen, while her nipple was being mashed against your face. You tried to yell for her to back up, but she wiggled her chest around as you opened your mouth, forcing some of her breast into your mouth and further crushing your head. You managed to push some of her flesh away from your face with your arms, but now her breast was compressing your chest and you couldn't breathe. After a few minutes, you heard Juli say, "Success!" and lean back. When her breast stopped crushing you, you saw that all of her toils had yielded results: the strip of her right bikini now had a small expansion of cloth just wide enough to cover her nipple. You were amazed how long it took Juli to achieve such little coverage; the red fabric was wrapped tightly around her nipple, her entire areola was still visible.
"Now, for the other one..." Juli turned so she was perpendicular to you, giving you a nice view of the sides of her breasts. You were amazed at how perky they were; they jutted from her body, and were incredibly round. You could even see her nipples poking outwards. Juli started pulling and stretching her left bikini now, as her right breast swayed back and forth from her movements, inches from your body. As Juli struggled with the stretchy fabric, her right breast swayed from side to side, towards and away from you. Then Juli leaned ever so slightly towards you, and the side of her breast was squashed up against the mirror and you. You were flattened with your arms at your sides, and forced to feel all of the vibrations through Juli's flesh as she fought with her bikini. A few times, her breast would swing away from you, before coming back and pounding you into the mirror. This time it took her considerably longer to fix her bikini, and you were left to be crushed against her for quite some time.
Juli eventually finished fixing her other strap and leaned back, leaving you to hang from the tape. She stood right in front of you, and admired her handiwork. You slowly reformed, unflattening yourself from the mirror. Juli looked at you, not knowing she had ever even crushed you, and said, "Well what do you think?" she stuck her chest out, showing off how her nipples were now covered by tight red cloth, and wiggled her jugs back and forth to show it off. The strands of fabric going from Juli’s  vagina to her breasts swayed and danced as her breasts swung back and forth. You watched her jiggling globes and said, drooling, "I think it's really hot." You could feel your swimshorts slowly getting tighter as your penis throbbed at the sight of her. Juli giggled and said, "Well thank you! Now hold on, I gotta fix my hair, it got a little ruffled when I was adjusting the cloth..." Then Juli bent really close to her locker door, pressing her breasts on either side of you. You could feel her breasts press against your erection from both sides, and pin your hands to the mirror. You were almost up to your chin in her cleavage as Juli brushed her hair back and pruned her eyelashes daintily. As you wiggled your arms, sending quivers through Juli's breasts, she laughed and said, "Enjoying the view?" You were about to respond when she pushed her breasts together, covering your face. She only heard a muffled agreement, and laughed again as her breasts continued to jiggle from your tiny movements.
