End
Instead of being out in the sunshine with his friends this fine Sunday afternoon, Jason was lifting weights in his basement gym. He needed the practice if he was going to make a try at the Juice Bar record.
_Bulk's gonna be really ticked off when I make that thousand-and-ten,_ he thought with a grin. He set the warm-up weight barbell back on the cradle and pulled off his red tank top to wipe the slight sheen of sweat from his body. Then he got up to add more weights onto the bar.
Just as he lay back down on the bench and gripped the barbell, the door opened and in bounced Kimberly.
"Hiya!" she chirped. Her short skirt flipped up dangerously high as the door slammed behind her and she skipped over to him.
"Hey Kim. What's up?" Jason asked, taking his hands from the bar and looking up at her.
"I just came over to_." Kim's voice trailed off abruptly as she looked down at him. She was suddenly mesmerized by the play of his expansive pectoral muscles under the taut, tanned skin. _And his biceps are huge!_ she marveled, as if noticing them for the first time.
"Earth to Kim?" Jason said. "Came over to what?" The look on her face was unreadable, but she was starting to look... a little horny?
Abruptly, Kim sprang into motion. She threw her leg over the bench and sat down on his pelvis, straddling his hips. Her eyes seemed to glaze a little as she reached out and began running her palms all over Jason's chiseled torso.
"Oh, wow, you're built," she whispered.
Jason was aware of the growing excitement in his shorts and he reached to Kim's tiny waist to lift her off before she noticed. At least that's what he started to do. As his strong fingers closed around her waist, Kim's hips began to rock. Almost unconsciously, she slid her crotch back and forth across his loins. Jason's growing bulge twitched. His hands tightened convulsively around her waist as his cock started to swell, stimulated by her ever-increasing tempo.
"Oh, man. Kim, you . . . ." Jason trailed off into a groan and his eyes closed for a moment. He opened them again just as Kim met his gaze. "Kimberly," he asked suspiciously, and a little hesitantly. "Did you just . . . hit a hormone spike?"
"Yeah, I think I did, . . . uh, am," she said, sounding a little dazed. "Jason, you better do something quick!" They stared at each other for a heartbeat, and then she let out a little gasp. "On second thought, just hold still!" She leaned forward and ground her clit into him, bracing herself more firmly against his chest as her hormone level shot off the chart. "Oohh, this feels good," she purred.
Kimberly held his eyes as she eventually sat up straight and untied the knot in the front of her midriff top, pulling it off, baring her pert breasts to Jason's unbelieving eyes. Jason groaned and, quickly stripping off his gloves, reached for them. His big hands covered her mounds completely and he squeezed. He kneaded for a while as Kim continued to ride him, then he grasped the hard rosy tips between his thick fingers and pinched. Kim moaned deep in her throat and arched her chest forward.
"I think . . . ohh . . . I think we have too many clothes on," Kim panted. She got up just long enough to peel her now-soaking panties off. The satiny, pink lingerie dropped to the floor and tangled around her ankles briefly as she got distracted watching Jason shove his shorts down. His long, thick cock jutted straight up, twitching with excitement. She got shed of her panties quickly and threw her leg across the bench once more.
Jason grabbed his straining tool in his fist as Kim straddled him again. He gave it a few small pumps, then held it steady for her as Kimberly positioned herself above him. His cock pulsed when the head met her entrance. Her juices ran down and coated his member as she settled herself into final position. Then she sat down.
Kim cried out as she was impaled. Their pubic hair meshed and Jason's swollen balls pressed against her ass as she ground down on him hard, making sure she had all of him in. Then she started to bounce. She had to balance on the balls of her feet to get high enough for the long strokes she wanted. Jason's hands on her waist helped steady her.
"Oh, God!" he groaned as he started bucking his hips, slamming up to meet her. He wasn't going to last long, he knew. Kim's hot little tunnel was squeezing him so tight! He gritted his teeth and tried to hold back the flood as he pulled almost all the way out, then slammed upwards, pulling her forcefully down to meet him. They pounded hard and fast, over and over, Kim's tight tunnel gripping almost desperately at his long, fiercely pistoning dick.
When Kim felt herself getting close, she leaned forward and put her hands on the barbell, gripping it tightly. She continued to ride him for all she was worth until she felt herself on the razor's edge of a monster orgasm. She shortened her strokes, grinding her burning clit against Jason's pubic bone as hard as she could.
"Ah, ah, ah," her moans wound higher and higher. "Jason, I'm coming!" she yelled as she felt the fire start to rage upwards from her cunt.
"Come on, baby," Jason gritted out through clenched teeth. "Oh, yeah." He raised his head and clamped his mouth on her nipple as Kim's body tremored all over and her cries of ecstasy peaked into a scream. She sat back up again as she gasped for breath, Jason's hard cock still pistoning her cunt.
"Harder. Faster!" he urged, lifting and lowering her quivering, ecstatic body onto his aching, rock-hard tool. Kim picked up the pace again, bracing herself once more against his chest. Their slapping flesh sounded loudly in the room as he bounced Kimberly up and down frantically on his long, thick pole.
Jason roared as the come shot out of his rod into Kim's thrashing body. He grabbed hard onto her hips and held her pressed tightly against him as he bucked sharply a few times and emptied his balls.
"Whew! Thanks, Jase," Kim panted, smiling as she lay limply across his chest. "I just suddenly needed that."
"Your welcome," Jason answered sardonically, trying to recover his breath. "Any time."
Kim giggled as she pushed herself up to smile down at him. "I'm gonna have to come over and pump iron with you more often."
