Steamy fantasy

I was chatting with someone recently and shared this fantasy, so I thought I'd type it up and share it with you all. I work out at the gym a lot, running, cycling and swimming. I like to wear tight running shorts and tight jammer swim shorts. The endorphin release from the exercise combined with tight lycra makes me horny every time. As soon as I've finished exercising I head to the sauna and steam rooms to relax. The pool area where the rooms are is mixed sex and everyone just wears their swimming stuff inside - going from pool to showers to hot rooms and back. Mostly it's men inside but there are a couple of hot women who frequent the rooms, one is particularly sexy. She is small, olive skinned with long, luscious dark brown hair and eyes that are so dark brown they are almost black. Where most female swimmers wear all in one costumes she wears a very small light pink bikini and when she leans forward her heavy tits strain at the fabric revealing their true shape. I long to slip my hand inside and cup her breast, feeling her nipple harden in my palm. When she emerges from the pool the bottoms become slightly transparent and you can make out her pussy lips and small mound of hair above them. Like me, she prefers the hottest part of the sauna - the top bench - and she likes to lie down or recline if the room is not busy and there's enough space. The few times I've been lucky enough to share the sauna with her I've pretended to be too hot and moved down a bench, so my head is level with her body. As she reclines and closes her eyes to the heat I get an amazing view of her. The thin strings of her bikini knotted at her thigh. I imagine reaching over to pull it loose. My cock swells in my trunks but the hot room is brightly lit and it's hard to hide a hard on. I stay as long as I can, then hurry out into the cold shower. After a quick cool down I head into the steam room. Here it is intensely hot and steamy. It is also pretty dark, just a few low-level lights and I allow my thoughts to return to her body and my let myself grow fully hard. I begin to fantasise about her joining me. We both recline slightly on the benches at right angles to one another. My head near her feet. The couple of other people in the room leave after a few moments and I turn and focus on her through the mist. My hard on raging in my shorts. Suddenly she sits up and leans over towards me to look at the temperature gauge which is above my head. Her top slips slightly and her beautiful breasts hang right in front of me. I can clearly make out her nipples. She quickly looks me over and then lies back again. Even through the steam and dark I can't imagine she didn't see the huge bulge in my shorts. I'm aware of my breathing and for a moment I think the room is amplifying the sound. Then I realise it's her. She's matching my deep, rhythmic breaths, a quivering excitement audible when we exhale. As I fixate on her crotch, she opens her legs and runs her hand the length of her body and down and over the small pink triangle of fabric, her lips clearly swollen now. My cock twitches, rock solid inside the skin tight lycra. Then she slowly pulls the bikini bottoms aside revealing her smooth, shaven lips topped by a neat, trimmed triangle of thick black pubic hair. It glistens in the steam. Her wide open hand slides over her smooth belly and then down between her legs. As she slides it back up she traces her pussy with her finger tips up to her clit. Then down again, this time spreading her lips, holding them open for me to see before running a finger between them and up to her clit again. She presses down hard and begins to circle it, pushing her hips forward. I have to release my cock. I push my shorts down, my nine inch length twitching involuntarily. The thick elastic waistband lies across the bottom of my shaft pushing down my balls. It acts like a cock-ring and I'm impossibly hard. I peel back my foreskin and turn back to see her sit forward slightly staring at my cock, her finger still on her clit. I begin to stroke myself, looking at her pussy lips and her dark staring eyes. She slides her fingers inside herself then moves her fingers back to her clit, using the juices as lube. The steam machine kicks in again and the hot mist builds around us, almost unbearably hot. She gulps for breath, her eyes wide. I begin to stroke faster and faster my precum mixing with the steam, my cock slippery. I roll the foreskin up and back for her. Hold it down hard. We are both stroking fast now, breathing in the boiling thick air, watching each other, her fingers occasionally dipping into her cunt then pressing down hard on her clit. I'm getting close. Suddenly she stares directly into my eyes and says one word. "Cum." I don't know if she means me or her but I can't hold on. I cum hard. My cock pulsates and thick streams of spunk coat my stomach. My body convulses but my eyes are still on her. She bucks her hips, throws her head back and moans deep and long. Her wide spread legs shake, her hand hard on her clit. She jerks forward and exhales fast, her eyes just open, looking at my cock. We both recline, trying to catch our breath in the stinging steam. I rub the cum into myself, the wetness of the room helps to dilute it. I lift up my ass to pull my shorts back up and when I look up I just see her tight butt receding into the darkness towards the door. Her bikini bottom like a thong between her ass cheeks. She pulls the fabric out and smoothes it down as she sways her hips walking, disappearing beyond the door.
