The Tai Chi Instructor

You were feeling good. More than good. The gym was doing wonders for everything you once worried about. Working out was said to make your body and mind feel better and it seemed to be working. You were taking more classes than ever. Tony joined you on a few but passed on others. Spin class and yoga were fine with him but swimming and Tai Chi weren't his 'thing' he admitted when you invited him to those two. It wasn't a big deal, leaving you time to focus on yourself and find some classes that suited you.
Swimming at first was a little scary, just standing in the pool and doing aerobics with a bunch of older women who giggled at the sight of you. You didn't know if it was because you were the only young one here or something else but they ended up doting on you every time you came to class. Some would offer to bake for you or ask for your help while clinging close. It was cute of these old ladies to gush over you, something you weren't used to but enjoyed. It was especially nice that most of these older women, though acting frail, were bigger than you and could easily lift you around in the water.
When you didn't have your swimming aerobics classes, you joined the Tai Chi class. It was run by an older bird, someone who you wouldn't have thought to be older than you until one of the students shyly asked his age.
His name, you found out on the first day through introductions, was Kass. His feathers were a brilliant blue with his wings reaching far. He wasn't as fit as Tony when it came to muscle but more so soft. It looked as if you were to touch his pecs, your hands would sink in but still feel the hard muscle underneath.
You often found yourself ogling his chest, trying to concentrate on the movements of his wings but getting distracted by his chest. You were embarrassed, knowing you were with Tony but it never hurt to look, right?
You kept telling yourself that as you continued going to Kass' class.

“Today, we're going back to basics.”

Kass had a soft voice that left you feeling warm inside. Tony's voice was boisterous and left you jumping when he greeted you from behind but Kass had a soft voice that would be perfect for narrating anything. He could narrate your grocery list and you'd still feel like you were on a cloud. It made you stay in his classes if you were being honest. Well besides the eye candy part.

“We have a new student today, so it's best we go back to the basics for everyone to catch up.”

You hadn't even realized, looking around the class until you saw a familiar clash of orange and black waving at you! Tony must have snuck in behind you, surprising you and giving you a triumphant grin. You shyly waved back, smiling but feeling slightly guilty. You wanted to listen to Kass' voice and let your body relax but now with Tony behind you, you felt this wave of guilt hit you. He was unaware of your feelings, clearly knowing you weren't falling for Kass. You didn't even know what you felt exactly. Maybe it really was just a little crush and would go away. But when the class started and everyone followed the movements with him narrating on how every movement should be slow and calculated, you almost forgot Tony was there. It was like a trance, feeling relaxed as you easily copied the moves that you had learned a few weeks ago.
Kass seemed to keep darting his eyes around, half lidded and inviting, until he stopped on you and gave a smirk. It made your heart pound against your rib cage, making you almost lose your concentration. But you continued on, unable to pull your eyes away from his.
A wink and you were flushed from head to toe if possible.
You thanked whoever was out there that Tony snuck in behind you so he couldn't see your face. It probably would have told him everything that was running through your mind.

“Hey, buddy! Surprised ya, huh?”

As you stood after rolling up your mat, a slap came from behind on your back that almost made your breath escape you! You wheezed forward, laughing nervously as Tony came up to throw an arm around your shoulder and happily greeted Kass.

“What a class! I'm not so good but my lil buddy here is almost a pro! I'm Tony!”

Tony held his hand out to Kass who happily took it, looking in between the two of you with his eyes lingering a bit too long on Tony's arm still around your shoulder.

“I'm very glad you could join us, Tony. We have been working on our technique for a few weeks now. In fact, you've caught on so well, I was wondering if you'd like a few extra lessons?”

The offer came out of nowhere, leaving you stunned to the point of your jaw dropping but you made sure to clench it before nodding slowly. You couldn't rely on your voice at first until Tony said something. It wasn't anything weird, right? Kass was just being kind, right?

“Woah! How cool! Look at you, bud! Already getting extra lessons! Better not take advantage of my co-pilot here, ya hear me?” Tony said with a laugh, clearly joking but with the look in Kass' eyes as he looked you up and down it was already a sign of these lessons were going to be about something other than Tai Chi.
“Do not worry. I won't keep your co-pilot long. Just enough to work on our technique together.”

You gulped, wondering what was in store for the next lesson.
It came sooner than you realized when Kass asked you to stay before Tony could drag you out.

“A-Already?”

You were flustered, getting pressed in between the chests of both men. You were right about Kass, how plush his chest was and soft like a pillow but firm as if one of those expensive ones people splurged on. Tony was still rock solid and left you shivering when you got a whiff of his smell.

“If you don't have anything planned. I thought it would be best to start today so we can go over what is planned for the next few lessons. You don't mind me borrowing my student, do you Tony?”

The energy between the two was overpowering, leaving you a weak mess and wondering what was going on. Tony seemed to get the idea, a look of uncertainty on his face but nodded slowly.
He looked down at you, reaching down to ruffle the top of your head before looking back up at Kass.

“How long will it take? I was hoping we could have dinner or something?”
“Oh come back in about an hour? It shouldn't take that long but Tai Chi is about taking your time to perfection. My teacher taught me that. So I'd like to help out others.”

You turned to wave as Tony left, a smirk on his face before he closed the doors to the large workout room. When you turned to Kass, he had stepped closer with that sultry look in his eyes. It left you feeling like a puddle dripping onto the floor.

“Shall we get started?”

-

The curtains were closed, there was music playing softly in the background and you were clutching the bar used for the ballet classes attached to the over sized mirrors while Kass knelt in front of you.
It had just started out with him behind you, showing you where you were supposed to breathe through the movement until he came to close and you felt a bump.
A bump that not easily mistaken.

“Oh my. I do apologize. I know you and Tony are... intimate. But if I may be forward, I do find the appeal he sees in you.”

You couldn't resist that voice even if you tried and you truly did try as you turned around to look up at him only to have him lead you to where you now stood.
You couldn't say anything as he pulled your workout shorts down, humming at the sight of your hardened cock. It was hard not to get excited when your crush was here, ready and willing. Even more so when Kass slid his flowing jogging pants down to show off that bulge you felt earlier.

Precum was already beading at the tip, the sight of it making your mouth water. His was similar to the color of his beak, dark but large enough to almost press against your knees which almost worried you. Expecting that you would switch positions, you gasped when Kass started to gently massage your cock with the tips of his wings and his tongue poked out to lick at the tip!
The sensation was strange, a rough tongue but a soft touch to the base. You were shivering, knowing this was wrong but with the soft touches and the smell of Kass and wild flowers surrounding you, it was over.
Kass stared up at your from his knees, his eyes still leaving you weak and wanting. Something about them left you needing this. If this hadn't happened, you knew it would gnaw at you until it burst.

“K-Kass...”
“Shush, now. It's alright.”

With that, you nodded and allowed him to continue. It started with a few licks until he started to take you fully in! You were a little worried by the beak but when it gently scrapped against your skin, your knees shook and you moaned loudly over the music!

Something caught your attention near the door, worried for a moment that it was someone about to come in but when Kass started to tease your opening with his tongue, you lost all thought about the door. It didn't matter if you were about to get caught or the janitors came knocking, you wanted this to last as long as it could.
Kass pulled away, licking from base to tip before using his feathers once more to tease you enough to cause you to almost weep.

“We really should hurry. Your friend will be joining us soon, I believe.”

You remembered Tony, the haze of pleasure clearing only for a moment to let in the guilt that tried to settle in. You tried to tell yourself that you weren't even together, technically. It should be fine.
When Kass reached up to tickle in between your legs that sweet spot between your asshole and balls, all those thoughts flew out and your legs almost buckled. You knew if anyone walked in, the sight of you bow legged and head leaned back to stare at the ceiling would be one no one would ever forget.

“Should we stop?”
The tone Kass used was teasing, a playful sound of laughter coming from his beak that left you looking down wide eyed behind your glasses as you shook your head almost frantically.

“W-We still have time, right?”

You looked for the clock even though you already knew there wasn't one. Kass always reminded everyone in class that there was no rush with Tai Chi and a clock would only make a class distracted.
The teacher chuckled, nodding before starting to tease you again.
You leaned against the cool mirror behind you, sighing to yourself before the sound came again.
It was someone. You caught the eye of a familiar someone. Your eyes lowered, almost feeling guilty until you saw what Tony was doing to make that noise. He was clearly touching himself behind the door. So bold of him to do it in the back hall but it only made you harder.
Kass seemed to notice, adjusting his position enough to give Tony a nice view of the both of you. You were almost sure he was going to invite Tony in the for the show but instead almost swallowed you whole!
The moans inside the workout room bounced off the walls, leaving you barely able to stand on your legs as Kass' throat surprised you by squeezing you tighter than you've ever felt.
You forced your eyes open, looking at the door where Tony opened it more to have his cock the only thing in the room as he jerked himself off openly. It was hard, harder than you've ever seen it before and it made you wonder through this misty haze of lust if he was getting off to getting cucked. He knew what Kass wanted by how he spoke and how badly they both wanted it. So maybe this was all according to his plan?
You shook your head, clearly knowing Tony wasn't that quick to pick up on things.

All thoughts left you when Kass started to tease that spot again, leaving you gripping the bar and groaning! Tony wasn't able to hold himself back just as much as you and Kass now, walking into the room and with one final hiss through his teeth came all over the wooden floor! The sight of Tony cumming to Kass sucking you off left you making a mess in Kass' mouth and all over his beak. The gooey mess against his dark beak made it look even more obscene. You couldn't help but slide down the mirror and sit in front of Kass as he started to jerk himself off to completion, making his own mess on your already flaccid cock! You reached down to mix the mess in your fur, smiling to yourself. His cum smelled just as sweet as he did.

Tony seemed to gather himself, coming over while still panting heavily.

“You two... wanna get dinner?”
Kass smiled up at him, looking at you with a cock of his head.

“Shall we?”

It felt as if this was all planned out and you were completely left out of the loop. At this point, you didn't mind. Having dinner between these two hunks of muscle was like a dream come true and you decided that you wanted the both of them. Not just one or the other.
After getting cleaned up along with the messes you three left, it was time for dinner for the three of you which lead to Kass inviting the two of you to his home for desert. As Tony ran ahead even though he didn't even know where you were going, Kass pressed a peck against the side of your head.
This felt right and you were happy you decided to take these extra classes.
