Bruce was just getting into bed after a long day when she came.
She climbed in through the window, as was befitting for one nicknamed "Cat". Bruce was completely oblivious to her presence since she landed so softly on his floor. She smirked at his cluelessness and lightly crossed the room to where he was just buttoning up his pajama top, with his back to her.
"Hey, kid," she whispered, causing him to jump in surprise. He turned to face her and he relaxed after seeing who it was.
"Selina…w-what are you doing here? You scared me," he stammered.
She smirked at him again. "Why do you think I'm here? I wanted to see you."
"It's nighttime, though. I need to get to-" he was cut off when her lips suddenly touched his. Bruce's eyes widened in shock and stayed that way when she broke the kiss.
She leaned in towards his left ear and seductively whispered, "You won't be sleeping for a little bit, kid."
Bruce could feel himself start to get hard at her seductive tone. Before he could say anything, Selina pushed him backwards onto the bed. She quickly discarded her boots and socks and lightly jumped on him, straddling his hardness, which caused Bruce to let out an accidental moan. That turned Selina on even more. She leaned down towards him and roughly crashed her lips onto his. It was an awkward kiss at first since Bruce had no experience kissing whatsoever besides the little one they shared a couple nights before. After a bit though, he learned to just let her take the lead and put his hands on her waist, lifting up her jacket and shirt slightly to gently rub the smooth skin underneath.
She sucked his lower lip into her mouth and gently sucked on it, with the occasional nibble here and there. He was so caught up in the pleasure that he forgot to breathe for a while and she could hear him inhale heavily through his nose, which Selina thought was cute.
Eventually, she let go of his lower lip and he surprised her by instantly going back to her lips, this time licking them, asking for entrance. She opened her mouth enough to let him go inside. The result was absolute heaven for both of them. She met his tongue with her own and they danced together for the longest time before Bruce did something else. Selina felt his hands slide down from her waist to her butt, gripping it softly, as if nervous to do so. She purred a bit to let him know it was okay. She could feel his hands tighten on her hips as he kneaded the flesh through her pants with his hands.
By this point he was completely hard. Bruce wasn't necessarily "big" since he wasn't done developing yet, but he still topped off at a little over four inches in length.
Without breaking the very heated kiss they were sharing, Selina proceeded to unbutton Bruce's pajama top. Realization suddenly hitting him, Bruce reluctantly broke the kiss, much to Selina's disappointment.
"Wait," he gasped, warm breath touching his face as they both breathed heavily. "I never…I don't…"
Selina could see his cheeks turning red in embarrassment, her eyesight aided by the moonlight streaming through the window that helped brighten up the room a little. She smiled sweetly and pecked his lips, reassuring him, whispering, "Don't worry. I'll guide you through it. Just relax and let me do the work until your instincts take over."
Bruce greatly appreciated her soothing words and exhaled heavily in relief, nodding. Selina again went back to his lips, but this time she thrust her tongue into his mouth, exploring every crevice she could find, tongue running over his teeth as his tongue coiled around hers. She went back to unbuttoning him. When the last button was undone, he helped her slip the shirt off and onto the floor.
Bruce's torso was mesmerizing for Selina. She wasted no time gliding her hands across his back and sides. She broke the kiss to stare at his chest. Despite being skinny, Bruce's torso was well defined and would turn any girl her age on. She then bent down a bit to kiss his chest lightly, trailing kisses down his chest and stopped at his belly button and left a big, wet kiss there, causing Bruce to moan a bit.
Taking the initiative, Bruce grabbed the hem of Selina's jacket and began to lift it up. Selina hurriedly removed her jacket, tossing it to the floor, as Bruce began to lift up Selina's shirt. Selina raised her arms upright and let him remove it, leaving her in nothing but a bra from the waist up.
Bruce took a minute to admire her very fit torso, eyes traveling up and down, particularly resting on her bra, where her boobs were. Selina noticed this and, making direct eye contact with him, slowly reached behind her and unclasped her bra. She then let it fall and tossed it on the floor, baring Selina from the waist up.
The lust in Bruce's eyes was very evident by that point. Selina gently took his hands and planted them firmly on her breasts and let him experiment with them. He gently squeezed one, then the other and kneaded the flesh a bit. When he started to play with her nipples, Selina let out a sharp gasp and her eyes screwed shut. Bruce ran his thumb across her nipples and gently pinched them with his thumbs and forefingers, eliciting more gasps from Selina.
Selina had had enough by that point. She sprung forward, engulfing Bruce's mouth in yet another heated kiss, tongue coiling around his and sucking on it from time to time. Her hands reached down to the top of his pajama bottoms and fumbled with the button for a bit before getting it undone. Bruce lifted his hips off the bed and, with eager help from Selina, slid them off, leaving Bruce completely naked in front of Selina.
After adding Bruce's pajama bottoms to the pile of clothes on the floor, Selina broke the kiss and her eyes rested on Bruce's member, sticking up at full length. She took a second to take it all in. The cut head of Bruce's member, from which a drop of pre-cum was dripping from. His scrotum, completely hairless, with his two testicles encased within, hanging far enough down to symbolize that Bruce had at least gone through the stage of puberty and growth where he could cum. Her eyes went to the patch of skin above his member, where very little pubic hair was present.
He's still just a kid. But tonight I'm gonna make him a man, Selina thought.
And finally, her eyes took in his thighs, where no hair was present. She took a moment to run her hands down them, causing Bruce's member to jump a bit at the unexpected touch. She then reached up to her pants button and proceeded to unbutton and unzip. She quickly pulled her pants off, followed by her underwear.
Now they both had nothing to hide from the other.
Selina straddled Bruce's legs and he could feel her smooth legs rub against his mostly hairless ones. His hands went back to grip her nice, fit hips. She smiled at him.
"Ready?" she asked.
Bruce could only nod, slowly at first, then more frantically.
Selina lifted herself up a bit, Bruce's hands never leaving her hips, and slid forward to where her entrance was directly above Bruce's member. She grabbed onto it for the first time, causing Bruce to arch his back in pleasure. Selina gently ran her thumb across the tip, spreading the natural lubricant, careful not to accidentally hurt him. She then pointed it straight up, made direct eye contact with him, and lowered herself down, to the point where he was completely buried inside of her. Not being a virgin, Selina experienced no pain, only pleasure.
Bruce gasped loudly, involuntarily bucking his hips up, gripping onto her butt more tightly. Selina took a second to adjust to the member inside of her and for Bruce to calm down a bit. She then put her hands on Bruce's shoulders to support her and lifted herself up, to the point where only the tip of Bruce's member was inside of her, before going back down. The experience made them both moan at the same time. Selina lifted herself back up and Bruce thrust up into her. She went back down and back up and Bruce did the same thing.
This went on for about a minute, her lifting herself back up, him gripping onto her hips and thrusting back up into her. She was surprised when his hands moved from her butt to her waist, gently pushing her to the side. Selina took the hint and lay down on the bed as Bruce went on top in between her legs, all without withdrawing himself from her. Selina, being the flexible girl she was, wrapped her legs tightly around Bruce's skinny waist, holding him to her for a bit. Bruce bit his lip, reining himself back in, before thrusting his hips into her and back out.
Selina wrapped her arms around the back of his thighs at first, caressing the smooth skin, before moving up to where they rested right below his hips, which were slowly thrusting in and out as Bruce tried to find a feasible rhythm. Being inexperienced, it took him a bit before he could find himself going at a somewhat slow but steady pace, thrusting as deep as he could go into Selina before almost withdrawing himself, only to go back in again.
Selina did everything she could to make his first time special. She gently massaged his skin, even sometimes gripping onto his butt, helping him with his thrusts. She also made sure to moan for him, voluntarily and sometimes involuntarily, so he would feel more confident.
Eventually, she found herself unable to contain her climax and released her juices all around his member, moaning and gasping all the while, clawing at his back, which would leave some scratch marks, but wouldn't be painful for Bruce to endure.
That completely set Bruce off. He could feel a pressure building up in his balls.
"Selina…" he gasped. "I'm gonna…"
Selina pushed him back and out of her, much to Bruce's surprise. He seemed a little frustrated that she stopped him before he could reach his climax, but mostly he looked confused and a little hurt that she did that.
Poor kid, he's not sure if he's done something wrong, Selina thought, before leaning forward and taking his entire member into her mouth in one go, being very careful not to accidentally hurt him with her teeth. Bruce gasped loudly and his hands sprung to the back of her head, entangling himself in her hair, holding her there for a moment. Selina gagged a little, but focused her attention to bobbing her head back and forth, purring for him, to increase his pleasure as much as she could.
With a moan and a thrust into her mouth, he spurted what cum he was able to produce, which Selina swallowed willfully and loudly, her throat making noises as it worked to quickly swallow his seed.
Completely devoid of energy, the couple fell down on the bed, with Bruce resting his head on Selina's chest, both panting heavily and Bruce beginning to break out in a sweat. Selina gently stroked his soft hair and held his hand, gently running her thumb over his. She kissed the top of his head as he drifted off to sleep and cuddled with him for a while, listening to his breathing.
When Bruce woke up the next morning, she was gone.
