The door to the private studio opened with a blast of warm air. It was bad enough that my wife dragged me to yoga on a Sunday afternoon, but I didn't sign up for a hot studio.
My wife paused at the door and looked back at the trainer in the waiting room. "Geez Nick. It's so hot in here!" After several weeks of free sessions at our gym, she wanted more personal attention to make sure she was doing everything just perfectly. Couldn't blame her for that. At our age, one bad move could lay you up for weeks. But I still couldn't figure out why I'd let her drag me along.
"Of course its warm. Better for your muscles." He pulled his t-shirt over his head and tossed it aside. "If you're uncomfortable, feel free to lose the pants. The studio's closed for the rest of the day so it's just us."
The studio walls were mirrored, making it easy to watch her peel off the baggy yoga pants. I couldn't argue with the results. Her new yoga fetish had definitely sculpted her body, muscles peeking out from her panties when she bent just the right way. Tossing her pants casually aside and standing in just her panties and top, she seemed so comfortable with her body too, another nice change.
"We'll start with just some warm-up stretches." Given how much we were all sweating, that seemed somewhat unnecessary. I tossed aside my t-shirt for a little relief.
After a few minutes, I had the basics down and started to relax. I'd been running a lot and the stretching actually felt pretty good. I also didn't mind watching my wife relax into poses that pushed her full breasts forward, stretching out the little tank top she'd worn, or watching her ass cheeks flex under the skimpy panties as she bent forward.
As she moved into down dog, her palms and feet pushing against the floor with her ass high in the air, he walked to her side. He slid one hand under her waist, pulled her ass even higher, and laid one arm along her spine, pushing softly to straighten her back. I tried to focus on my own position but couldn't break my eyes from the mirror long enough to straighten my head. He slid his arm up her spine, sliding his fingers into her hair and flattening her head to align her back perfectly.
"Nice. Now drop into upward-facing dog." I almost crushed my hardening dick as I dropped toward the floor and looked to the ceiling, but at least the change got his hands off of her. I knew instructors repositioned people all the time but I wasn't quite prepared to watch anyone but me reposition my wife like that.
We went from upward-facing dog to plank a few times and I was amazed how strong my wife had become. She'd never been able to do push-ups, which was one of the reasons she'd started taking yoga in the first place.
"Side plank, arm raised toward the ceiling." I saw her drop to a knee as she spun looked toward me, her shirt raising with her extended hand, revealing the top of her panties.
Nick scowled at her position. "I can live with the knee being down but you at least need to hold your back straight. Here, let me show you."
I watched in disbelief, struggling to hold my own position as he dropped to his knees on the floor behind her. He grasped her hips firmly and forced them forward and back. "Stack your hips, like this. Great. Now stretch the spine." He fell to a side plank behind her, mimicking her position. His hand stroked up her side, then slowly up her arm to grasp her hand. His body pressed firmly against her back, forcing her chest toward me. Her nipples poked against the fabric, obvious even through her sports bra. His head leaned in as he whispered to her, making her giggle and drop her position. I couldn't stand it anymore. I sprung up and spun to face them.
"Seriously? Why don't you just go ahead and fuck her while you are at it!" I could feel my face reddening with anger as my erection started to wilt.
She pulled up on all fours and crept toward me. As she reached up to stroke my semi-soft dick, she grinned up at me mischievously.
"What a fabulous idea! But I really need to finish my workout first don't you think?" She ran her teeth along the length of my cock which was once again sticking straight out under my gym shorts. A final downward stroke and she was back on her feet, dropping her shirt and bra to the floor as she went. She glanced back over her shoulder at me and smiled. "It is so hot in here, isn't it!"
His pants were off by the time she joined him back on her mat. "Now that you're all stretched, how about a few couples poses that you can do at home? I'll demonstrate and you can follow?"
I was completely flabbergasted. And yet I couldn't help but agree. I took a seat on my mat and crossed my legs. "Yeah. Sure. Whatever you say."
He led her through a series of poses. First she laid flat on the mat and he hovered over her, their eyes locked as he talked about how erotic just breathing together could be. He rose and squatted near her feet. Taking each foot in opposite hands, he pushed her legs apart and her knees towards her stomach. "They call this Happy Baby pose, be careful not to force her legs too far." It was incredible watching him so close to my naked wife's body, so embarrassing when he turned to explain to me what he was doing. As he repeatedly pushed her legs up and back down, I could see her pussy stretching open too, her thighs already wet from the attention.
He released her feet and pulled her into a seated position. They sat across from each other, legs spread and feet touching. Holding hands, he leaned back, pulling her toward him, her face lowering toward his swollen cock. They froze in place for several moments and then switched, her leaning back and pulling his face toward her. Each time, they stretched into each other further and further. Just as I worried about how far they might go, he turned to me. "Your turn?" I hurried to take his place and he went to sit behind her.
As I leaned backward, he pushed her further by laying his naked body along her back. The second time, he pushed her head down into me. "Go ahead, lick, but don't suck." I still don't know how she bent so far forward, but the feel of her warm tongue circling my hard dick made me even harder. Then he pulled her back. I knew I'd never reach her pussy but he stopped as my mouth reach her tits. "You too. Lick, but don't suck." It was excruciating to use just my tongue on her swollen nipples, flicking them and hearing her moans. I wanted so much to suck her big boobs fully into my mouth.
After we'd gone back and forth several times, he broke our hands apart, moving mine to her inner thighs. "This kind of stretching tightens these muscles so you need to work them gently to prevent cramping." I gratefully complied, pushing my thumbs into her thighs, edging ever closer toward her pussy. She returned the favor, rubbing my thighs as her thumbs and fingers occasionally brushed against my balls.
