Girlfriend's Friend in the Sauna

My girl was tall and athletic but very much about the cardio. Brown hair, brown eyes, into cycling and running with a history of field hockey. She was absolutely gorgeous but also a bit shy and quiet, fairly vanilla. I had worked on that and we did have a great sex life, but it was a tad limited at this point aside from a few moments which stood out… one in particular I’ve already documented here that involved her friend.

Her friend Kat was shorter with a naturally curvy frame. She had spent years at this stage doing CrossFit like a maniac and it showed. She was lean and slightly more muscular than she had been a few years before. She had small tits, though she wasn’t flat by any means, and her legs and her ass in particular were spectacular.

She would come across to see us a few times a year, but aside from the occasional drunken grope nothing else had happened like that amazing threesome in the intervening years.

My girl and I had had a tough year with separate work stresses that had limited how much exercise we could do. Neither of us was unhealthy, but we had been working at getting back to our previous selves. My girl had been running and I had been doing circuit training again for a couple of months and was already feeling stronger and healthier.

With that had come a massive increase in my sex drive that unfortunately had not been matched by my girl, and I was feeling pretty pent up to be honest.

When Kat arrived she came to say hi and gave me a hug as she always did. She smelled amazing. I gave her a peck on the cheek and she smiled, lingering a half-second longer than necessary. As she pulled away she cast a small, cheeky glance down to my hard on that had pressed against her tummy.

I had gotten hard in a second at her contact, my hormones going nought to sixty in the same time. I was fucking ready to go.

She grinned and licked her front teeth deliciously, her body shielding both the motion and my hard on from my girlfriend who, to be fair, wasn’t watching anyway.

I raised a challenging eyebrow and she gave a slow nod… then we both quickly turned away.

They were going for a walk and I had plans to sort out some house jobs and catch up with them later. We decided to meet up at a local sauna hotspot that we had been going to about once a week.

When the time came I met them there with their gear and we all changed. My girl always wore a bikini, but Kat wore a one-piece swimsuit that was super tight and it just reminded me how her body looked. I had to work extremely hard not to stare. I was also very glad that I had picked a pair of fairly loose-fitting board shorts rather than a speedo.

We all went into the sauna and discovered that we had it to ourselves. I sat next to the furnace and Kat sat across from me. My girl sat next to me.

The temperature was higher than usual and I was pleased, as I like it really hot. Kat and I had obviously decided without words to make it a challenge. I suggested putting some water on and she nodded, raising a defiant eyebrow.

“Ah, a worthy opponent…” I joked, splashing the water on.

“Oh god, another one!” my girl joked, sticking her tongue out at Kat. “Don’t encourage him!”

“What?” Kat said, batting her eyelids. “I like it hot, my love…”

My girl rolled her eyes. “Fine, I’ll just do shorter intervals.”

After about five minutes my girl went for her first cold plunge and Kat and I sat opposite one another, sweating from the heat.

It was seconds after the door closed before Kat’s foot languidly reached across and rubbed over the front of my crotch. I was so hard it hurt.

“Ffffuck…” I moaned in a breathy whisper.

She laughed. “Hmm, now there’s a thought.”

I looked at her and couldn’t keep the hunger out of my eyes. She flashed me a grin that was equal parts amusement and baring her teeth in challenge.

I started to move my foot up to her in kind when we heard the outer door open again and her foot fell back to the floor.

The next interval was another five minutes before my girl was off again, and this time I got in first. I slid my foot up the inside of Kat’s leg until my toe found her clit through her suit and she moaned wantonly, throwing her head back.

“Ahhhh fuck…” she looked back at me. “You need to be careful… I don’t think this is going to be nearly enough…”

I leaned forward then and replaced my foot with my hand, rubbing her pussy through the smooth fabric of her suit. I could feel her heat beneath. From the way the fabric moved against her folds I could tell that she was slippery wet.

I increased the pressure and she moaned too loudly, so I leaned forward to cover her mouth with mine. Our tongues wrestled for thirty seconds as I worked her cunt. She snaked a hand into my lap and began to rub my cock through my shorts at the same time.

Then we heard the outer door again and leapt back to our separate seating positions. The temperature gave us cover for why we were so red and flushed.

“You guys have been in here nearly twenty minutes,” my girl said, looking at us both. “Are you going to go and plunge?”

We looked at each other and the challenge remained.

“Truce?” Kat said, reaching out her hand.

I nodded and shook it, and we both rose. I let Kat lead the way because I’m a gentleman… definitely not just because I wanted to watch her go.

We headed out and in the open air we moved towards the plunge tanks. Normally I would have picked one of the single-person baths that were kept colder, and I think Kat would too, but this time she walked to the larger, multi-person ambient plunge. As she climbed in I saw her look back over her shoulder quizzically to see if I would follow.

I hesitated only for a second before I did.

Once in the water we feigned indifference to one another, chatting as our hands explored beneath the surface.

I placed a hand between her legs in the cool water and another on her breasts, rubbing and tweaking a firm nipple through her suit.

Her hand dipped into the waist of my shorts and found my shaft, which had remained rock hard despite the cool water. She stroked me in a steady rhythm, her thumb massaging the spot beneath my glans at the top of each stroke. Goosebumps raised all across my body as I felt my balls threatening to tighten already.

We spoke calmly, making small talk, but her eyes gleamed and her lips curved up at the edges in amusement as she stroked me.

I felt the need to step it up. My hand in her crotch pulled the gusset of her suit aside and I slid two fingers into her hot, creamy depths in one move as my thumb landed on her clit and began a steady rhythm of my own. She cut off mid-sentence, her body shuddering slightly.

She hadn’t come yet; I remembered the way her walls squeezed when she did, but I knew she was several steps closer. I gave her a wicked grin when she opened her eyes and looked at me, her eyes dark and her mouth open and wet.

She shook her head and gave a small breathy laugh, then looked around furtively before leaning in and shoving her tongue into my mouth.

We stayed that way for about thirty seconds, which was twice as long as I dared, but she wouldn’t release me.

We finally leaned back from the kiss, our hands still working and both of us starting to breathe more heavily, when we heard the sauna door open again and finally separated.

We both tried to control our ragged breathing as my girl came back across and climbed in with us.

We stayed for another few minutes before we all climbed out. Kat and I headed straight for the sauna but my girl said she was about done and wanted to sit by the fire.

“Are you sure?” I asked. “We have about twenty minutes left I think.”

“Yeah, I think I’m good,” she said. “I’ll get a hot drink and just sit out in the air a while.”

Kat punched my arm as she passed. “You coming back in or are you too chicken, big guy?”

She stuck her tongue out at me and I felt a small involuntary start… I wanted to win, but I also wanted to stick my tongue in her mouth and other things in other places.

My girl rolled her eyes then gave an exasperated laugh.

“You two,” she shook her head. “You should get it over with and just fuck already.”

I froze. Kat did too. We both turned to look at her to see if she was kidding and she laughed.

“Yes. I know what’s going on,” she shook her head. “We’ve been here before, right?”

She shrugged. “I guess I don’t have a problem with it if you want to…”

My jaw fell open. I looked at Kat and her jaw was on the floor as well. Then she closed it and tilted her head at me questioningly.

I looked back to my girl.

“I love you.”

She nodded. “I know.”

I leaned in and kissed her and she kissed me back.

“Don’t make a mess!”

I shrugged and chuckled.

Kat still looked like she couldn’t quite believe it, but she turned to walk back towards the sauna and I swear she had more roll in her hips as she did. Her ass was round and firm, toned but so juicy, and I wanted it badly.

When we got back into the sauna I hung my towel over the door window. Kat wasted no time at all, grabbing me from behind and reaching around to stroke me through my shorts again. She pressed her body against my back and her heat was hotter than anything the sauna could muster.

I couldn’t let her do this for long. I wanted her body and I was so worked up I was almost ready to explode.

I turned around and pulled my cock out of my shorts before wrapping one arm around her back. My other hand wasted no time reaching down to pull the gusset of her swimsuit aside again, rubbing up and down her slit to spread her wetness.

I kissed her then, hard, and felt a quiver of excitement in her pussy and a fresh wetness. I couldn’t wait any longer.

My hands slid the straps from her shoulders, pulling the suit down to free her delicious tits before I scooped her up with my palms on her ass. She reached down to pull the gusset of the suit to one side as my mouth found one of her breasts. I licked around the nipple before sucking as much of the soft mound into my hot mouth as I could, and simultaneously I began to lower her.

She was ready and her hand guided me inside her in one fluid movement as she slid down my cock to the hilt. We both gasped.

I sat back on the wooden bench with her astride me then, removing my mouth from her breasts as she kissed me again and began to move.

I kept my hands on her ass cheeks, squeezing and kneading and encouraging her movement as she rose and fell on her knees as far as the position would allow. It wasn’t long before I heard her moaning.

I returned my mouth to her breasts, sucking the other one in and lashing her nipple with my hot tongue as I felt the pressure building.

Her speed became more ragged and I knew she was close, so I lightly nibbled her nipple between my teeth.

“Oh FUCKING hell!” she moaned so loud I was sure anyone outside could probably hear, and I felt her coming on my cock, her walls rhythmically gripping me. Out of nowhere I was suddenly exploding inside her. My balls throbbed and my cock pulsed as I shot ropes of come into her orgasming pussy, and I released a too-loud groan of my own as we both threw our heads back. Our bodies gave a few more spasmodic thrusts that were almost too much for my overloaded nerve endings as we both came hard.

She collapsed onto me then and I held her, still inside her but softening, as we both tried to move as little as possible for several long moments, our over-sensitised bodies riding through the sensations.

When we’d both finished she looked me in the eye. Her pupils were huge and her eyes glassy. We gave each other one last, long exhausted kiss before she gingerly lifted herself off me and collapsed back against the opposite bench.

We stayed like that for about another minute before we heard a knock on the door signifying our time was up. I hastily pulled my shorts back up over my spent cock. I saw Kat hurriedly checking her suit and we both laughed.

I gestured ahead for her to go first and she shook her head and gestured instead. I nodded theatrically and rose, and she grabbed my ass and squeezed as I did, giggling to herself as we left the sauna.

I checked behind us and we had left it clean… but there was definitely the unmistakable smell of sex in the air.
