The next day I was just getting out of the shower when Nikki called me. For once it was a video call, which was a surprise. I wrapped a towel around myself before answering. She was in her bedroom when I answered the call and the video feed started. The way she was holding the camera made it hard to tell - it mostly only showed her face - but she didn't appear to be wearing anything. Her shoulders were bare, and I couldn't see any tank top or bra straps in obvious view. Maybe I was just being optimistic after last night when she said she was usually naked when she was alone in her room.
As soon as I picked up she said, "Nice towel," with a wink. Before I should reply she continued, "I want to go shopping. Come with me?"
"Sure," I said, "what do you need?"
"A new bathing suit," she said.
That was surprising. "You do know this is December right?" I said.
"Gee really, is it?" she said, "I had no idea." The sarcasm was apparent. She panned the camera around to show me the mini-Christmas tree she had set up in the corner of her room. Then she panned it back to her face, although I got a quick glimpse that seemed to confirm she was naked. This was a new development, but certainly not one I was unhappy about.
"Okay, fine you know what month it is," I said, "can I least ask why you want a bathing suit in December?"
"Friends of mine are having a hot tub party at their house tonight," she said, "and I just finished trying on my old suit. I'm not happy with it." She held it up in front of the camera and then tossed it to the ground, shaking her head at it. "So I need a new one. And maybe we can find you a new bathing suit too."
"I don't need a new bathing suit," I said.
"I've seen yours," she said. "Trust me, you do. And I want you to come to the party with us too."
I rolled my eyes, and she stuck her tongue out at me. "Meet me at the mall in an hour? And be ready to try on swim suits," she said.
"Okay fine," I said. "Anything else?"
She bit her lip and blushed a little. "Maybe...drop the towel before you hang up?"
My cock - which had been stirring anyway at the thought that she was naked while we were talking - sprang to attention. I cleared my throat, and then before I could chicken out, I gave an exaggerated shrug, said "Whoops," and slipped the towel loose from around my waist. It fell to the floor and I was on display for her.
I saw her look down at me, and the blush on her cheeks brightened. She took a deep breath. "I...uh...didn't think you would really do that. But...thanks," she whispered. Possibly because she was distracted, she pulled her phone back far enough that I could see her too.
She was naked. She still had a heart shape shaved into her pubes. She had pierced nipples, which I had known because she talked about them from time to time, although this was the first time I'd seen them. Her breasts were full and seemed disproportionately large for someone her height, which certainly wasn't a complaint, just an observation.
We looked at each other in silence for a few moments, then finally she cleared her throat. "Well, um, see you soon 'kay?"
"Okay," I said and we both hung up.
About an hour later I walked in the main entrance of the mall. Nikki was already there, sitting on a bench. She was wearing big fuzzy blue boots that ended about mid-calf, and a short black skirt. Topping this off was a parka that matched the boots in color, although not in fuzziness. Jumping up when she saw me, she came over and hugged me, then stepped back and smiled.
"Weren't you cold getting here like that?" I said, gesturing to the skirt.
"Oh please," she said. "I went to a Catholic high school, I used to wear a kilt all winter waiting for the bus. Plus this is easier to take off than pants."
"Well I can't object to that," I said with a wink.
"So I can try stuff on easier," she said with a laugh, giving me a friendly shove.
"Sure, sure," I said. She linked her arm in mine and led me off into the mall.
We headed to the one bikini store that was open year round, for reasons I have never been able to understand.
As you might imagine being mid-December the bikini store was basically dead, even though the rest of the mall was full of holiday shoppers. There were no customers in the store when we got there, and only one employee. She was a cute college-age looking girl, not much taller than Nikki, wearing a nametag that said Sarah. Sarah and Nikki hit it off right away once Nikki explained why we were there.
In fact, almost from the beginning I sensed a kind of flirty vibe coming from Sarah and aimed at Nikki, who did not seem to be discouraging it at all. They got deeply involved in discussing all the arcana involved in bathing suits, which quickly went over my head.
Before long Sarah led us through an alcove at the rear of the store leading to the fitting
rooms. There was a padded chair in the corner where I sat while Nikki started trying things on.
She came out to model each suit as she had it on of course. She wanted to know what both Sarah and I thought, and we were happy to oblige. Sarah started suggesting alternative suits, or different sizes, and helpfully running back out of the fitting room area into the main store to get them for Nikki.
Every time she did this, Nikki would flash me. She would pull the suit top down, showing her nipples, or slide the bottoms down to show off her pussy. The first time it happened I was shocked, and Nikki laughed at the expression on my face. From then on though, I just enjoyed it.
My main concern was hiding my erection - which was tenting my pants very seriously - from Sarah, since I didn't want to get us kicked out of the store. I soon realized I had nothing to worry about though, because she only had eyes for Nikki.
The suits she was bringing Nikki became more and more revealing, and I also realized it seemed like she was intentionally bringing tops that were too small, so that they covered even less.
Nikki didn't seem to mind. In fact, as she went back into the fitting room to change, she stopped closing the door all the way, leaving it open a bit more each time. She also asked Sarah to help her do up a few suits, a process that Sarah helped with eagerly but seemed to involve a lot more shoulder and neck touching and stroking than was strictly necessary.
I didn't mind any of it. All of it was turning me on, so much so that when the store phone rang and Sarah had to go answer it, I was hoping to take things a little further.
Nikki came out in the latest suit, a tiny little red number that barely covered anything. She struck a series of poses for me. Then, she turned so she was facing away from me. She bent over, and pulled the suit bottom aside, spreading her legs also so I had a fantastic view of her pussy.
I couldn't resist that. I cleared my throat so that she looked over her shoulder at me, and then while she watched I slowly moved my hand towards her, raising an eyebrow.
She blushed, but nodded. I slipped a finger inside her. She was so wet that it slipped in all the way with no hesitation. She moaned, then covered her mouth to muffle the sound. She started to move her hips back and forth, riding my finger. I started sliding my finger around in tiny circles inside her, causing another moan.
I don't know how long we kept on like that, but then next thing I knew I saw movement in the corner of my eye. Looking over I saw Sarah standing there, who I had managed to completely forget about. She was frozen almost in mid step, standing in the alcove from the front of the store. A swim suit, completely forgotten, hung from her hand at her side.
She looked very flushed. It was obvious she could see what was happening, but she definitely didn't look disgusted. Quite the opposite in fact.
Stifling another moan, Nikki looked over and saw her too. Sarah's eyes widened and she turned to go.
"No," whispered Nikki, and she turned back. Nikki raised a hand and made a small 'come here' gesture. She didn't stop riding my finger though.
Sarah slowly walked over. Nikki reached up and touched her face, first with one hand, then with the other. Then they kissed, slowly at first, but then with deepening enthusiasm. Nikki's moans were loud, but still partially muffled by Sarah's mouth. As they made out, Sarah reached up to the suit tie at Nikki's neck and undid it. Held on only by the strap around her back, the bikini top fell down in the front, exposing her breasts.
Sarah's hands found Nikki's breasts and started playing with her nipples. I couldn't directly see it from the angle I was at behind Nikki, but there was a mirror on the wall that gave me a decent view. I could definitely hear that Nikki enjoyed it though. She moved on to kissing and nibbling on Sarah's neck. This all continued for at least a few minutes.
Then Nikki put her hands on top of Sarah's where they still cupped Nikki's breasts. Nikki squeezed Sarah's hands, essentially using them to pinch her own nipples. That was enough to tip her over the edge and into orgasm. I could feel the muscles contracting around my finger. Her moans were muffled by Sarah's neck, but still loud enough that all three of us could hear what was happening.
After the orgasm I was expecting that as usual Nikki would feel shy and guilty. I slipped my finger out of her, and she proved me right by adjusting the bottom and top of the suit so that she was covered again. She was blushing heavily.
Sarah too looked a little embarrassed, and was sporting what might soon be a new hickey on the side of her neck.
All three of us exchanged glances during an awkward silence.
"Well," I said, "I guess we'll take this one?" I pointed at the red suit, looking at Nikki while I said it and she nodded.
