Picking her weights back up with a smile on her face, Riven resumed her exercises while Ezreal's ambulance grew quieter and quieter while speeding off into the distance. Taking a quick break she grabbed her handy supplement-drink, taking a deep swig of the thick and sticky juice that filled the bottle. Licking her lips to wet them, she wiped the sweat from her brow as she took stock of the gym. Udyr, Janna, Graves, Sejuani, Shyvana, all the regular visitors were there. Now was the time to show them who the top dog was. Grabbing both of her dumbells she started, counting to herself silently as she grunted, pumping steel at a frantic pace. With every rep she could feel her muscles stiffen, almost bulging- no definitely bulging with power. Too late she felt the muscle creep up on her, all over her body. Flinging herself to the ground, she held tight to the weights as she found her body instinctively doing pushups, muscle hardening across every inch as something within her pushed her hard and beyond her limits. Groaning in pleasure Riven felt her muscles tense as a new alien feeling greeted her. Against the tight spandex of her shorts she could feel it, something was growing, stretching the crotch of it. Shooting up faster than she expected she found herself almost immediately in front of a mirror, the dumbells more and more resembling something to hold rather than actual weight. Between labored breaths and unconscious lifting her eyes skimmed down, and she swore she could feel her heart stopped as the obvious outline of her newfound erection pressed out against her shorts. The bulge was beyond obvious even, with the head forcing the waist of her shorts off of her, the pink head greeting her with a bead of precum.
Inexplicably Riven felt her tongue flick out across her lips as she stared, entranced. She couldn't take her eyes off of the throbbing piece of meet in her shorts, the precum slowly trickling over the elastic waist and down the front, her heartbeat racing as she felt her mouth fill with drool. She felt drugged, intoxicated, she was beside herself in this daze when Janna walked up, grabbing the stiff rod and massaging it slowly with only the tips of her fingers. "My, Riven.. this muscle is quite well toned, mind showing me.. how to use it?" the sultry woman asked with a wink, turning and tiptoeing just a little to raise her bottom into Riven's view, her butt swaying left and right slowly. Biting her lip as her heart raced Riven heard the dumbells drop from her hands, the sound of the weights smashing into the ground distant, as if another world as her eager hands slid over Janna's well toned and shapely bottom. Taking a handful she felt desire surge from her cock, and in the next moment she was slamming the full length of her cock into Janna, shaking the experienced woman with force she had only felt so many times. Janna's moans filled the air sweetly and it wasn't long before the other champions were finding their way out of the gym, suffocating in the stuffy smell of Riven and Janna's sex, a pool of sweat and their juices beneath the blonde as Riven rocked her on the ground, ignoring yet another one of Janna's orgasms to ram into her even harder as she struggled to remain coherent. She was a hot mess, gasping for air and moaning, her hair glued to her face as she arched her back up as Riven plowed her. Starting to moan again Janna grew louder and louder as her entire body shook with a huge orgasm, finally coaxing Riven's hot and sticky semen into her pussy, easily flooding the blonde as the excess dribbled out beneath her. "YOU'RE BREAKING MEEEEE" she squealed as Riven thrusted even harder, glob after glob of her cum squirting out as she rammed Janna's cervix until the torrent of semen subsided.
Exhausted, sweaty, and with aches all over Riven rolled off of Janna and lay on the ground, breathing hard. Finally softening her cock began to flop over before she felt Janna's soft hand take hold around the base, blood slowly flodding back into it as it hardened under her grasp. "H-how about we exercise s-some more..?" Janna near-whispered with a smile, licking her lips as her hand slowly stroked Riven's cock. "If you think you can keep up, Blondie."
