Yuri POV

You might think these threesomes with Tae would hurt my relationship with Tiffany, but instead we grew closer. Tiffany was giddy all the time. She had a normal upbringing, if maybe a little conservative because of her religion, so her hookups with a guy not her boyfriend were exciting "break the rules" kind of things for her. From her point of view, yes, she was acting sluttish, but she had her boyfriend's permission so it was okay. For me, it was so exciting to see my girlfriend taken by another guy. I can't explain it, but just thinking about it made me dizzy with excitement. Yes, it was gut wrenching, but so thrilling.

I didn't like the way Tae and Tiffany acted around each other (outside the bedroom). Their actions were a little more intimate, touchy-feely than before -- not like boyfriend/girlfriend, but more than platonic friends. My friends noticed it, and some of them even told me I better watch out for Tae because he was making moves on Tiffany.

I tried telling Tiffany my concerns, but talking about it got me excited and hard (despite the anguish), so it always ended up with us having amazing sex. My reaction got Tiffany believing it excited me when she flirted with Tae in front of our friends -- which it did -- so she started doing it more, delighted by how kinky and demented I was.

To celebrate my birthday, Tiffany threw me a party with about 30 of our friends. She looked amazing. I guess maybe I should describe her. She's a head shorter than me at 5-3, with a petite slim body. She's got pretty hair that goes passed her shoulders, and a girl-next-door pretty face that match her bubbly, happy-go-lucky personality. Her breasts are small (she wears a 32 b cup) but perky, and she's got amazing long legs with slim pretty feet. See danced a lot in high school and college, and is kind of tom-boyish, and prefers jeans and flats over skirts and heels.

Tiffany hates wearing pantyhose, feeling they're too constricting. So it surprised me that not only did she wear a dress to my birthday party (a little black number), but also sheer nude pantyhose, and spiky high heels. I didn't know where she got the high heels, I didn't know she even owned any. But she looked incredible! The dress was low cut so it showed the soft swell of her bosom (I think she wore a push up bra as her boobs looked bigger than normal), and it end way higher than her knees so it showed off most of her legs. And her legs looked even more amazing than usual in the silky nylons and high heels.

Even though it was my birthday party, Tiffany spent as much time with Tae as with me. I think our friends thought it was because she was tipsy from beer, but given how touchy-feely the two of them had been lately, I'm sure all my friends thought Tiffany was cheating on me with Tae. More than once when the three of us were clustered in a group with other people, Tiffany ignored me completely, her eyes and attention solely on Tae.

One time Tiffany came up to me and whispered into my ear, "Doesn't Tae look so hot tonight?" She giggled seeing the flash of excitement on my face, then walked away.

Around midnight I looked around for Tiffany but couldn't find her anywhere. Tae wasn't around either. They'd been all over each other all night, so I was pretty sure I knew what they were doing. Most of the people were still there so their absence wasn't noticeable, but soon it would be if they didn't show up soon. Just as I was about to have an anxiety attack, they walked in ... together! WTF, couldn't they have at least come in separately?!

Tae said something about going out for a smoke, but Tiffany's hair was disheveled, her cheeks flushed, and her dress creased. In other words, she looked freshly fucked! I could tell, and so could all are friends. Many of my friends looked at me questioningly, wondering why I wasn't taking a slug at Tae. My gut wrenched with jealousy and insecurity, and at the same time my cock was hard as a rock.

After I didn't do anything, the party got back to normal, although there was a lot of whispering and gossiping going on. I tried to catch Tiffany's eye but she ignored me, still giving Tae all her attention. Finally when I thought I couldn't take it anymore she came over and pulled me aside. We had a few moments of privacy, and she kissed me open mouth. "Can you taste Tae, he was in my mouth not long ago," she whispered into my ear. Then she pushed my hand up her dress. The upper thighs of her pantyhose were soaked. "That's Tae's, his cum, spilling out of me."

It was too much, I lurched and came in my pants. Tiffany smiled delightfully. "I guess you're having a good birthday," she giggled.

"Fany-ah, wait," I pleaded. "Everyone knows you fucked Tae just now. They all think you're cheating on me."

She shook her head and gave me a knowing look. "They might suspect something, but they don't know." I wasn't so sure about that. I cleaned myself up and we re-entered the party holding hands.

Later that night back at my apartment, I pushed Tiffany's dress up around her waist. Her black thong panties were visible through the sheer tan nylon of her pantyhose, and the pantyhose from her crotch to mid-thighs were soaked. "Tae cums a lot," she giggled.

"Where did he fuck you?" I asked hoarsely, my fingers tracing the wet area of her pantyhose.

"Outside, in the back. He fucked me against the fence."

"Weren't you worried someone would go outside and see you? A lot of people already think you're cheating on me." I pulled off her pantyhose and panties and pushed my cock into her. She felt loose and extremely wet. One good thing about this thing with Tae, she no longer insisted I wear a condom, finally deciding the pill was safe enough.

She shrugged, but I caught a flash of excitement in her eye. The excitement wasn't from my cock though, she barely reacted to me being inside her, but then Tae was a lot bigger than me. No, her excitement had to do with people thinking she was cheating on me. She'd been raised Catholic, and had always had the reputation of being a pristine, goody-two-shoes girl. Maybe she liked people thinking she had a bad girl streak.

As I moved inside her, she said, "In the middle of fucking me, we heard Sooyoung on the other side of the fence, talking on the phone. We had to stop until he left." She flushed excitedly. Sooyoung was my best friend, we'd been best friends since grade school. "God Yul, Sooyoung was two feet from us, on the other side of the fence, and Yul was inside me. What if he had opened the gate and saw us. How would you like that? Sooyoung seeing your girlfriend fucking another guy. Would you like that? Or maybe you'd want me to suck him off so he wouldn't tell anyone. Would you like that? If I sucked Sooyoung off and let him cum in my mouth?"

It was too much, I grunted and lurched and came. I collapsed onto Tiffany, physically and emotionally spent. We lay in the darkness, our bodies entwined. "I'm not sure how much longer I can do this," I said. "I mean, it's exciting, but, I mean, it's almost too exciting."

We talked a long time after that. It was exciting for both of us, but it had drawbacks too. Tiffany admitted it wasn't the best thing for her if everyone thought she was cheating on me. I was nervous throughout the conversation, because I thought she might break up with me, deciding she'd rather be with the more hunky Tae. I knew Tae would take her in a second, he'd always thought she was hot, and even more so now that he'd seen her naked and knew how great she was in bed. But to my relief she never even broached breaking up. Finally we decided to stop it with Tae.

Tae wasn't too happy with this. He hit on Tiffany a few times, and when that didn't work he threatened to tell everyone that Tiffany was a slut and I a cuckold. He screwed himself with that one, because that got Tiffany mad at him so if he ever had a chance with her, that was gone now. We told Tae it would be as bad for him as us if this ever got out -- like, what if a potential employer ever heard about this? That finally convinced him because all of us were about to graduate and we were all looking for jobs.

He moved out and I didn't see him again until graduation. I was graduating from the grad school and Tiffany and Tae from the undergrad main campus. After my ceremony, I walked across campus to meet up with Tiffany. When I got there I saw Tiffany across the lawn talking to Tae. It was pretty far away, but it looked like he was doing most of the talking. She shook her head as he spoke. He kept talking. She looked nervously around, then she said something to him. That seemed to satisfy him because he smiled and walked off. When I caught up with her I asked, "What was that with Tae? I saw you talking to him."

"Oh, um, nothing," she said. "He got a job in California, so he said goodbye." Then she hurriedly added, "Have you seen our parents yet?" I frowned. It seemed they talked longer than it took to say goodbye. But our parents were taking us out to dinner to celebrate, so I forgot about it as we went in search for them.

After graduation, both Tiffany and I searched for jobs in New York City. We both loved NYC, and we wanted to stay together. Tiffany was ecstatic when she landed a job in a big advertising firm as an assistant account executive, and I got a job with a big Wall Street firm. Tiffany's job didn't pay much but it was a good start, and anyway my job paid enough to make up for it. We rented a loft in SoHo and moved in together.

We didn't talk about Tae, or what we'd done with him. It's not that we were ashamed by it, or regretted anything. We were just too busy with our jobs and it was exciting to live in a big city like New York.

We went out all the time. There are too many great bars and restaurants in NYC to cook at home! I admit I gained some weight with all the eating out, but Tiffany managed to keep her slim figure by enrolling in modern dance and yoga classes with others from her office.

Tiffany really blossomed in New York, shedding her tom-boyishness. In advertising, you had to be stylish so she started wearing designer dresses all the time. I think she spent all her paychecks on clothes, but that was okay with me. I made enough for both of us to live on, and with her great legs I loved the way she looked in dresses and skirts, and now she even wore high heels all the time. Her company was old-school, where it was a no-no for women to go bare legged. I thought that would be a problem for Tiffany, because she hated wearing pantyhose. To my surprise, one morning I found her putting on thigh high stockings. It looked like she'd worn them before; one had the start of a run. That further surprised me. I didn't know she even owned any, and I'd never seen her in them. I asked her about it. She shrugged and said, "I've had these for a while. Maybe they'll be more comfortable at work." Seeing her roll the thigh highs up her long sexy legs made me crazy, and I attacked her. "Maybe I should wear them more often," she giggled. Needless to say, we both ended up getting to work late that day.

I felt proud and so lucky to have a girlfriend as good looking as Tiffany. She'd always been one of the prettiest girls in the room, but she really blossomed in NYC, and with her new clothes, she looked better than ever, a real head turner everywhere we went. It gave me a charge seeing other guys look at her, and men were so confident in New York that they'd hit on her, even with me standing right next to her. Tiffany noticed how this aroused me, and she started flirting with other men right in front of me. Nothing as outrageous as with Tae, but still it was a charge for both of us, and it always led to great sex. Sometimes during sex she'd whisper into my ear how hot she thought a guy was, making our fucking even more exciting.
