KARA MAKES A DISCOVERY JPC900 Superman returned to the fortress of solitude, he had spent the evening with Lois, as usual it had left him confused and frustrated .He sat in his study, closed his eyes and pondered his dilemma, every time he thought of Lois it gave him strong urges and conflicts. Tonight these were particularly strong, as he had kissed Lois for the first time, He drifted in a semi -conscious state he slipped into fantasy imagining wild liaisons with Lois as he did he began to feel aroused and started to fondle himself and bring himself to an erection as his excitement grew he lost his self control, released his belt lowered his trunks and started to wank himself .He sighed and groaned as his fingers ran up and down his enormous erection, new and erotic sensations swept through his body, it made him slump back in his chair, his excitement grew and he tried to stroke faster but his hand would not respond , his breathing became rapid and shallow , but with each stroke his rhythm slowed then his hand slipped from his penis, this startled him , but when he tried to sit up he struggled he was weak and sluggish . He rested and his strength slowly returned, then still feeling horny he tried again but each time he grew too weak to climax and he was paralysed even although he felt as if he had been hit by kryptonite he kept trying and trying. After almost an hour he was so dazed he did not notice Supergirl his 17- year-old cousin Kara arrive. At first she was embarrassed to catch him masturbating, but then she was intrigued as she watched him repeatedly try to climax then slump weak and drained. As she continued to watch she wondered if she could take advantage of him, she was feeling sexually excited. Kara crept away into the gymnasium, then she called out," cousin are you there, I am going to the gym to exercise will you join me?" startled by her call he was initially disorientated he tried to stand but fell back he recovered his senses "I will join you later I have a few things to finish. This pleased Kara as it gave her some time to work out her strategy. It was several hours later when he felt strong enough to join his young cousin in the gym."Hi Kal "she greeted him," Gee what's up you look washed out...hard day?" "yes " he replied "I was exposed to kryptonite.I still feel a bit shaky ," "come and join me on the mat and I will check you out...3 falls or a submission !" she said teasingly , reluctantly he removed his cape and prepared to wrestle with her. They circled each other, then unusually Kara locked hands with him in test of strength ,with minimum effort she forced him to his knees , rolled him on his back , straddled him and pinned him with one hand , "my you are weak !" she exclaimed ,"I could hardly feel you resisting , give me your hand" she pulled him to his feet , "that must have been powerful kryptonite, I have never seen you so weak as this before," "yes "he stammered ,"I need to rest" "sure" she agreed, "we had better check you out again later" , he slipped to his room to recover. It took him 5 hours then his superpowers returned, he tried to avoid Kara , but she was insistent that they check him over again , "I kicked your butt pretty easily , don't you want a chance to get your own back,,,,,,or are you afraid I will do it again " she teased ."Ok" he reluctantly agreed ," I will see you in the gym in 10 mins". When he arrived at the gym he thought Kara seemed different she had changed her costume and combed her hair, her skirt seemed shorter showing more of her shapely legs , she had a different attitude , feisty , sexy ."Feel up to it now , big boy or shall I pin you again ?" she seemed to be playing with him. She beckoned him on to the mat almost flirting with him , they faced each other then grappled for the best holds, at first she held back , but when she realised he was fully recovered , she started really fighting .but steadily he started to gain control , so she changed tactics , she allowed him to catch her in a head lock , as they struggled she brushed her breasts against him and rubbed her arms and legs against his groin, she was careful to make it seem accidental. Whenever he pulled her she thrust her breasts and hips , when she saw him gazing at her body , she knew she was making him horny . With a planned move she tripped him and they both fell to the mat, she freed one hand and then started to make them roll over and over each other. She pretended to try and escape his strangle hold but her real plan was to rub against his penis as often as she could. She noticed his trunks begin to bulge, then she could see the growing shape of his arousal. He let out a long sigh, swallowed hard, the rhythm of his breathing changed .They stopped rolling , Kara was still trapped in a head lock but had managed to lie across him she wriggled her hips and pushed her breasts into his chest..she felt him stiffen , again he swallowed hard then she noticed a slackening of his grip ,she drew her knees upwards and rubbed against his groin with her thighs. Superman recognised the same sensations he had experienced earlier, his eyes had a distant look, suddenly he felt tired, Kara sensed this, she knew she could break his hold but continued to wriggle and squirm stimulating his erection , which was almost bursting out of his trunks . Waves of erotic sensations were coursing through him , his pulse was racing..but he felt so drained!" Let's call it a draw ," he panted , "not yet "she replied , " I want to beat you again I found it so sexy overpowering you earlier ," as she spoke she wrapped her hand firmly around the shape of his erection and sensually ran her hand up and down its length..".and now I am going to do it again."...."Oh! .Kara " he groaned as his grip weakened and his chest heaved. "what .wh..at are you doing ...Uh ,,,I feel, so weak?" "I've turned into kryptonite " she smiled sexily tracing the shape of his throbbing penis with her finger. "Stand up! " she told him pulling him to his feet , he tried to pull away but she easily spun him around , held him firmly around the waist , stroked him again.."isn't this sexy " she was elated inside he was churning the mixture of fear and excitement was rapidly sapping his strength and his will. Kara skilfully undid his belt ,pulled down his trunks wrapped her fingers around his shaft and started to wank him." Why don't you stop me cousin .. Feeling a little weak?" she teased ,.His arms fell to his sides and he sank to his knees he was as weak as a kitten , Kara kept pumping him, his head fell forward his muscles collapsed , he was helpless now too weak to lift a finger, she stopped and stood over him ,pushing him on to his back with her foot , he struggled to sit up but fell back , finally he propped himself up on his elbows Kara stretched out her foot and rubbed it along his penis, as he fell back the sight of Kara standing powerfully over him caused him to orgasm and climax as he fainted with weakness.
