Striptease in the gym

Jess and Will, university coursemates, had moved into a flat. Instead of paying exorbitant gym fees, they installed a few pieces of equipment in the large hall. Just an exercise bike and bench with a bar and free weights, but that was ample. Plus, if the equipment was in use, neither particularly minded. The sight of Will's hard, toned legs blurring as he pedaled made Jess short of breath, and Jess's pectorals contracting under her lovely breasts as she bench pressed made Will swoon. So both were happy with the arrangement.

Will was on the bench, and presently removed his sweated through shirt, revealing his golden skinned, hard muscled chest. She muttered barely, "Dang..."

"Excuse me?!"

"Huh?" Jess grunted, glad that he couldn't see her blush through the sweat she had worked up.

"I distinctly heard you say "Dang." there. Presumably in response to my revealing my manly chest."

"Did not." said Jess, reverting to the childish interplay they employed during times of conflict.

"Admit it. I make you hot. Admit it, admit it". He leapt up and twirled around for her, flexing his biceps and grinning. She couldn't disguise how her eyes were drawn to him, and he chuckled.

"Christ woman. Just tell me how I make you horny, and I'll show you the rest."

"Fine. You make me horny. Now show me the rest." Will's eye's widened momentarily, but he decided to call her bluff. He untied the drawstring of his sweat pants, and pulled them down. Then Jess's eyes widened, as it became clear that he wasn't wearing underwear. He pulled down his trousers enough to give her a peek at the base of his cock, then yanked them up again.

"Hey, you said..."

"I changed the rules. Tell me again.

"You know what? Fuck you, you don't play fair."

"Who said we're playing? Tell me again."

The atmosphere had changed suddenly but unmistakably.

"Will, you make me horny. Please let me see the rest of your hot body. Please?" said Jess, her voice rising to a breathy whine on the last word. Will fixed his large, brown eyes on her small, pale blue ones, and unfastened the drawstring yet again. This time he turned, pulling the fabric down over his gleaming buttocks, allowing the baggy garment to fall to the ground. He stepped out, and turned round, smirking and lewdly concealing himself with one hand

"Tell me again. Actually, better still. Show me."

"Sh-show you?"

"Yep. Show me how horny I make you. Then everything will be yours to see."

What did he mean by that? Did he want to see... how wet she was? Or how hard her nipples were? Her body had no shortage of evidence of the effect his nudity had on her.. She slowly raised the hem of her t shirt and removed the sweat soaked fabric, revealing her sports bra. This bra was rather unusual in that it zipped up the front. She pulled the zip down, and her  tits sprang free for her nude flatmate to see. He nipples stood out proudly, and she thought she could feel and even see the scarlet nubs pulsing under his gaze. He moved closer, inspecting her. She fancied she could feel his stubble on her skin. Then he moved back, and said:

"Very nice."

But he didn't move his hand away. Not yet.

"But I wanted to see how horny you are."

Her cheeks burned even hotter. He could only mean one thing. So she dismounted the bike, bent over, and pulled away her socks and trainers. She stood in front of Will, who smiled at her encouragingly. She removed her little pink shorts, and  finally her knickers, displaying a small modest patch of hair. She kept her bikini line under control for swimming, but otherwise was au naturale. This was obviously to Will's liking, as his broad smile cracked into a joyful grin. It looked like he was having difficulty restraining what he hid under his hand, which was gently undulating over his bulge.

Now came the hard part. She sat on the bench and parted her legs, revealing her wet, unmistakably horny pussy.

Will crouched before her, instantly drawn to her and leaning in to closely examine her, the same way he had looked over every inch of her tits. She felt his breath on her soaking cunt, and shivered in response.

"Ok. You upheld your part." Will said thickly. He took away his hand, revealing a handsome but frighteningly thick cut cock, the head of which gleamed with precum. Jess gasped and arched her back for him without quite being aware of what she was doing. Her last sensible neuron sparked weakly, and she said:

“What the hell are we doing, Will?!”
“Fucked if I know. But I like it.”

He briefly excused himself to his bedroom, returning with a condom. He threw the foil packet on the floor (Jess decided to complain about the mess at a later date) and sheathed himself.

She spread her legs a little wider, as wide as they would go, and raised her hips up. Will lined himself up with her, and pushed in smoothly. Jess cried out at the feel of him. He deliciously filled every crevice of her, almost causing her pain. He grabbed her tits and started plunging into her while standing, presently letting go of her left to run his thumb over her cunt. Jess closed her eyes and savoured the deliciousness of it all, opening them when he suddenly withdrew. She caught the savage look in his eyes, before he flipped her over and started pounding into her from behind.

Jess moaned at the feeling of being taken like an animal, and the feeling of his strong, sure fingers on her clit. He experimented with the angle of his thrusting, until a shocked gargling noise from Jess told him that he was probing at her G spot. Her cunt pulsed faster and faster, tighter and tighter around his cock, until her orgasm rippled over her, nearly drawing his own climax from him. He slowed down, supporting the woman's limp, exhausted body, slowly teasing and edging himself to his own climax.

Finally he arched his back and groaned wordlessly, as he came inside her. He slumped over her on the bench and rested on her glowing back. Both lay motionless for a while, stunned at the sudden, quite unexpected resolution of the sexual tension between them. Jess was the first to move, and Will stood back, letting her up. To his surprise, she didn’t seem at all embarrassed, and made absolutely no attempt to hide her body. She smiled at him lazily.

“I’m going to take a shower.”

She sashayed towards the bathroom. God, what an arse she had on her.

“Well? Aren’t you coming?”

What did they do next? Tell me in the comments...
