Leisurely, Splash Woman rose off of Rock’s face, stepping right beside Rock’s head on her fin. The young robot gasped for air, even though he never needed oxygen, it was just another feature to make him seem more human. Now free of her blubbery ass, Rock looked around desperately for something to make his escape with. Instead of finding a weapon, he found his sister, now three times as big as he remembered. He stared long and hard at his bigger little sister, before saying, “Roll! What did Splash Woman do to you?”

“What do you mean what did she do to me? Don’t you like the new me?” Roll angrily muttered, not expecting her brother to react as he had. She wanted him to take one look at her and fall madly in love with her, not stare at her like he had never seen her before. Then again, she never planned for him to see her while pinned down by a maniacal mermaid.

“Huh? I don’t understand, why would I like you bigger?” Rock asked with a confused look on his face. He didn’t understand any of this situation. Why would the size of his sister matter to him? Why had Splash Woman tell him to kiss her ass before Roll arrived? Why was the antenna between his legs standing upright? None of what was going on made sense.

“Eyes upwards. Instead of looking at that cow, check out these utters,” Splash Woman sultrily said. Turning his eyes upwards, Rock saw Splash Woman holding her armor in one hand and rubbing her now naked breasts with the other. Roll stared as well, finding herself even angrier then before over Splash Woman having a set of nice double-Ds. Sure, Rolls set were closer to H-cups, but Splash Woman had a nice rack too and that was all that mattered.

The robot siblings stared at the perfect set of robot tits, but both of them noticed something else. Right near the top of Splash Woman’s fish lower body was a nice wet slit. Rolls eyes shot open at the sight of the fish machine's cunt, wet and looking to be filled. Gritting her teeth, Roll figured out what the robot was planning and found herself more angry then she could ever remember. She was not going to have her brother’s virginity stolen by this slutbot, she refused to allow it.

“What’s that?” Megaman asked as he looked at the strange hole in Splash Woman’s waist. It looked odd, like a pair of sideways lips that were drooling. Megaman couldn’t see any teeth, but he wanted to look closer to check.

Hearing the big hero’s question, Splash Woman smiled evily. It seemed that the great Dr. Light forgot to program the most important part of the male mind into his tin solider. At least he made him fully functioning. Slowly moving her body to his waist, she reached down and ran her fingers over the large member, increasing the roughness of Rock’s breathing. She looked one last time at him, enjoying the clueless look on his face.

“Let me show you what your goody-goody father and dumb, cow sister could never show you,” Splash Woman panted out, her arousal higher then ever before. She crawled on top of him, turning her back to him as let her fin wiggle against his feet. Megaman stared at her naked back, the bump of her buttocks visible. Splash Woman positioned his cock at her wet slit and slowly slid herself down on it, feeling the rich, velvety skin slide into her and fill her up so fully. She remained silent, instead focusing on the pleasure and Megaman’s moans. She felt the smooth, velvety skin of Rock's cock slide inside of her wet hole, stretching her and filling her insides with his warmth. She continied to drop her pussy down until her crotch touched Rock’s crotch. Wiggling to get comfortable, she made sure Rock had a good look at her butt as she sat on his cock.

“This is….incredible!” Megaman gasped out as he experienced sex for the first time. She began to slide herself up and down his cock, feeling inch of his robothood rub against her sensitive insides. Rock had his eyes closed and his mouth opened slightly as she maneuvered herself on top of him. She wiggled her hips a bit as she rode him, feeling his cock hit every possible surface in her pussy. She picked up speed quickly, bouncing on his waist like a pinball. She could no longer keep from speaking as deep, long moans escaped her mouth.

The best part for Splash Woman though, was that she still had complete control over Megeman's body. Sure, he didn't seem to be complaining right now, but he was still inexperienced. As such, Splash Woman then commanded his hands to reach up behind her, and grab her behind.

Roll could only watch in horror and envy as her brother grabbed a fat rear, and it wasn't her own! His fingers soon dug into the artificial scales, finding Splash Woman's ass was just as warm and soft as her inner reaches. His cock throbbed and his thrusts quickened as he squeezed the buns hard, finding the way their warmth squished in his hands to be very addicting. Also, for as amazing as it felt in his hands and repeatedly ramming its plumpness onto his crotch, Megaman longed to feel the butt back on top of his head and squeezing it from all sides. For the first ass he ever got to fuck, right now Megaman believed it was the greatest in the world.

Smiling in pure exstacy, Splash Woman bounced her ass on Rock again and again, plowing his shaft into her drenched depths as hard as he squeezed her buns. He was like a kid with a new toy, unable to let go of the fascinatingly hot and tight yet soft thing. As she started squeezing her bouncing boobies, she thanked the day Dr. Light realized that reproducing robots was more efficient that building one at a time. Not only would similar machines be made, but for as human as their appearances, that also meant their mating habbits would be the same as well, and as Splash Woman rocked her booty onto an eager Megaman, plowing his pipe in and out of her cunt and feeling pure pleasure surge through her chest, she wouldn't have it any other way.

As Megaman begged for more, only delighting his captor further, something very interesting happened. Looking in front of him, Megaman soon spotted a small opening between the fishy buns. Every time Splash Woman bucked her butt back as she rode him, it became visible. Unbeknownst to him, this artificial anus was also the work of Dr. Wiley to have another part of this sexbot to stick it into. Another unknown desire filled Megaman as reached toward the hole, only this time he did it willingly.

Just as Splash Woman was pleasantly surprised to feel her lover fucking her on his own, she screamed as she felt his metal digit plug her hole. She gasped loudly for no air, but unable to do anything else as a fascinated rock stuck his finger in and out of her sphincter, all while still thrusting his hips up into her.

Suddenly, as he continued, the pleasure overloading his circuits caused another reaction as one of his recently absorbed powers suddenly acted up again. With the ability of Vibrator Man, one of many examples that Wiley's imagination was dying, Splash Woman shrieked even louder as it happened inside of her ass. Rock even plunged his finger deeper into her, spurred on by her cheeks repeatedly clenching around his hand when she bucked forward.

Watching her brother both fuck and finger the slut of a mermaid was horrible for Roll in so many ways, but the worse was the burning desire she had to have Rock do all of that to her. Fixit had also installed a hole between her behemoth buns, and she could now clearly feel it as she watched Splash Woman's being screwed. To make thing's worse, the appropriately named, Hard Man's power was then activated in Rock, and the fishy robot howled like a wolf as Megaman plunged his entire and now giant fist into her ass.

“Fuck Yes! You’re a big boy, aren’t you? Yes!” She panted as her tongue hung out of her mouth and her bounces became larger and longer. She lifted herself right to the tip of Rock’s cock and then slammed back down, ramming him in at maximum speed. Every move she made got her orifices stretched out so far, but she felt only pleasure. Someone in her pussy with something in her ass, she had been longing for this for so long it wasn’t long before an orgasm rippled through her electronic body. She was jerking around on Rock, her pussy gushing out clear cum and contorting around his cock. It was too much for Megaman who came moments later.

“What is this!?” Rock screamed as an explosion of pleasure moved through his body. His hot fluid burst inside Splash Woman’s body, filling her artificial womb with thick cream. Splash Woman collapsed on top of him with him still inside of her and she laid her head on his chest. Lying there breathing deeply, both of them had matching happy smiles.

“No,” Roll wept softly, watching the man she loved make love with the enemy. She wanted to die right now, but more then anything, she wanted Splash Woman dead more than life itself.
