MOTHER-IN-LAW ADVENTURES PART 10
Sex in the Sauna With Mother-in-Law
Hot and cold sensations stimulate an erotic afternoon
My mother-in-law Madeline is a 55-year-old goddess. I fuck her more often than I do my own wife and I can’t get enough. Since the start of the new year, we’ve been spending even more time together than usual as we encourage each other with our fitness-related New Year’s Resolutions.
Though I’m 22 years younger than she is and in decent shape, I sometimes struggle to keep up with her, which is why I’m planning to do more high-intensity cardio. More sex, of course, but also running and whatnot. Non-sex cardio isn’t my favorite, so it won’t be easy to stay motivated.
Meanwhile, Madeline’s goal is to make her fantastic ass even better. She says she wants to be able to crush watermelons between her thighs and squat with a piano on her back. That might sound hyperbolic, but I wouldn’t bet against her. And I sure do enjoy watching her progress because it involves tight leotards and a lot of sexy grunting.
“Come on, Mrs. Worthington,” I say, standing behind her with my arms up to catch her if her mighty legs give out. “One more.”
She adjusts her grip on the 175-pound barbell across her shoulders before struggling through her final rep.
“I thought I told you not to call me that,” she says as I help her return the weight to the squatting rack.
I smile. “Sorry, Madeline. I thought being annoying would give you an extra burst of energy.”
She kisses me on the cheek. “Well, I finished the set, so I guess it worked. OK, let’s do 20 minutes of cardio, then hit the spa.”
She and my rich father-in-law own the gym we’re at. It’s one of those swanky health clubs with tanning beds, saunas, and massage chairs. Being from the other side of the tracks, I’m just glad the equipment isn’t broken and the locker room doesn’t smell like ball sweat.
“Seriously?” I say. “My legs are like Jell-O.”
“Suck it up, buttercup,” she says as she heads towards the treadmills.
I choose a machine directly behind hers so I can watch her ass while we’re running. She’s in front of a mirror, so I also get to watch her tits bounce. It’s the perfect carrot on a stick to get me through the workout.
There are plenty of hot women in the club, but I’m transfixed by the glorious MILF I’ve been fucking nearly every day since I married her daughter. Her skin is flawless and she has the form of a professional athlete. The motion of her hips as she tears it up on the treadmill reminds me of the way she rode my cock like a cowgirl last night.
Yet even with this visual stimulation, the 20 minutes on the treadmill feels like two hours. As Madeline increases her speed, I decrease mine to a point where I’m basically walking. By the time we’re finally finished, I can barely stand.
“Here,” she says, handing me her water bottle. “Take small sips.”
“I don’t know how you do it,” I say as water trickles out of the corners of my mouth. “You’re barely breathing heavy.”
“You’ll get there. With my help, of course. Now, let’s go do a 90-second cold plunge and then 15 minutes in the sauna.”
The latest health craze is extreme temperature exposure. The cold is supposed to increase your metabolism and boost your immune system, while the heat has been shown to increase muscle hypertrophy and improve brain function. It all sounds unpleasant to me, and so far, I’ve managed to avoid it. Today, I don’t have the energy to argue.
“OK, let’s get this over with.”
“That’s the spirit.”
The cold plunge is just a tiny above-ground swimming pool filled with near-freezing water. I dip a toe in.
“Holy fuck, that’s cold!”
She takes my hand. “On the count of three…”
Except instead of counting, she just pushes me in and jumps in after me. Immediately my heart starts pounding as though I’m being chased by a pack of velociraptors. I don’t know what color my lips are, but they feel blue. I’m in too much pain to appreciate Madeline’s hard nipples poking through her skimpy bikini.
My instinct is to wrap my arms around her, but she keeps me away.
“Down boy. That would be cheating. Come on, just 81 seconds to go. Focus on the clock.”
I’m shaking like those wind-up chattering teeth. I thought those 20 minutes on the treadmill were unbearable, but now I’d give anything to be back on there. It feels like I’m being pricked by a million push-pins at the same time.
At exactly 90 seconds, I hurl myself over the side of the pool, catching my swim trunks on a nail and tearing them off in the process. I hit the concrete with a thud. Luckily, my extremities are too numb to feel the impact.
“Oh, my,” Madeline says, trying to hold back a giggle. And that’s when I realize she’s staring at my dick, which has shriveled to the size of a thimble.
Out of the corner of my eye, I see two hot ladies in the jacuzzi hiding their faces in embarrassment for me. I cover myself before the beefy lifeguard can get a good look from his perch above the lap pool.
“Are you really laughing right now?” I say.
She wraps a towel around me and gives me a consoling hug. “I’m sorry. It’s just… well, you’re always already hard by the time I get your pants off. I’ve never seen you so — ”
“Small?”
“Oh, come on, dear, don’t be mad. I know it gets bigger, and that’s all that matters. Right?”
I sigh. “I guess.”
She smiles and takes me by the hand. “In fact, why don’t you show me right now?”
“What? Where are we going?”
“The sauna.” She drapes my torn bathing suit around my shoulders and leads me away.
There’s only one sauna chamber but luckily, it’s unoccupied. She cranks up the temperature to the maximum setting and sets the timer to 30 minutes.
“That should keep other people out,” she says.
Of course, it doesn’t solve the problem of the glass door. Stepping inside, I feel like a snake in a terrarium at the zoo. The glowing red coil is already doing its thing, pumping out crisp, dry heat like the exhaust pipe of a monster truck.
She kisses me, and my towel falls to the floor. My traumatized cock perks up at her touch. She takes it between her thumb and index finger and examines it like a jeweler.
“Hmm,” she says. “What I think this lil’ fella needs is a little mouth-to-cock resuscitation.”
She drops to her knees in front of me and takes me into her mouth. Immediately, my dick begins to inflate like a tire. It grows from a little mushroom cap into a cucumber, filling her mouth, stretching towards the back of her throat.
She cradles my balls with one hand while squeezing my ass with her other. Tender from an intense leg day, my muscles tingle as she works them over. From tip to taint she slurps and sucks, her head bobbing and twisting like a balloon in the wind.
Once she feels I’ve been “resuscitated” enough, she releases my cock and comes up from the floor. “See?” she says. “I knew it would get bigger.”
“Thanks to your magic mouth.”
I undo her bikini top and grab her firm melons. Her nipples are still hard from the pool. I give them a pinch, causing her to shudder.
She pushes me onto the bench. When my ass connects with the wood, it feels like I’m being branded. She kisses me again, driving away the pain.
In this heat, every movement feels like a marathon. My heart is racing as she rubs my throbbing cock across her entrance. Her steaming cunt is a juicy oasis in this otherwise scorching desert of a room.
She slips me inside her. Her body temperature is cooler than the air, which makes me wonder — is this what it feels like to fuck a zombie?
I’m on my back, which means I mostly get to lie still. Given our comparative fitness levels, this is the ideal position for us. I do my part by licking my fingers and massaging her clit as she bounces up and down on me. My scorched buns tighten, bracing me for each thrust. She squeezes my cock with her Kegel-powered pussy, the pressure making me as hard as a diamond.
“Your cock feels so good,” she gasps.
By now, we’re both sweating faster than the air can absorb the moisture. The sight of her perfect, glistening body silhouetted against the single light bulb on the ceiling is turning me on even more.
But the sauna is no place for tantric sex. I know that if I try to stay in here for the full thirty minutes, they’ll be taking me out in a stretcher, and I’ll look like a giant piece of beef jerky. Luckily, Madeline is close, too. I can tell by the gleam in her eye.
“Keep fucking me,” she cries. “Just like that.”
I roll her clit between two fingers as though I’m trying to get dried glue off of them. With the other hand, I squeeze her tits as though I’m trying to pop a balloon. She changes the angle of her hips, increasing the friction. Her thighs crush my sides. Her nails dig into my chest.
It’s all I can handle.
“Gah,” I grunt, as my balls tighten.
“That’s it, baby!” she shouts. “Cum for me!”
On her command, I explode inside her, emptying my balls and filling her with hot, sticky cum. The detonation triggers her orgasm and her whole body quakes. It feels like we’re on the surface of the sun as it collapses into a black hole.
When the euphoria subsides, I realize how dehydrated I am.
“We should probably…”
My parched throat won’t let me finish my sentence, but she gets the idea.
Outside the sauna, a small group of seniors has gathered. It’s hard to say how long they have been standing there or how much they saw, but I like to think we inspired them. We raise our water bottles and toast to them before chugging 32 ounces of cool spring water.
“I told you the hot and cold exposure is stimulating,” Madeline says as we head towards the locker rooms.
“I shouldn’t have doubted you. Maybe next time we can fuck on the treadmill. Then I won’t hate running so much.”
She laughs. “I sure do enjoy getting fit with you.”
