Roll was just enjoying herself, feeling the slippery juices spill from her cunt and the warm afterglow of her first orgasm. It had been incredible, but she knew that there would be bigger events ahead of her with her and Rock. She had seen that look on his face as her pussy ate the oversized fish, he loved it and that meant that he loved her. It was lust, but she would soon change that. She had her brother mesmerized and that was all she needed.

“Roll?”

Mega Man was no longer under Splash Woman’s control. Able to move he walked slowly to his sister, with so much on his robotic mind. He stood next to her, his erection throbbing almost painfully as he looked at her huge butted figure. Her soulful eyes turned to him and the fat around her buttocks and legs started to move back to their original positions. Her face got rounder and her breasts and belly expanded out, soon completely masking the bulge Splash Woman was making. Her huge, drooping gut pushed forward until it touched the tip of Rock’s cock. Groaning at the accidental touch, Rock backed away before he came on his sister. Roll giggled.

“So Rock, you never answered my question. Do you like the new me?” Roll slyly asked and got to her feet. She was taller than her brother now, his face only reached her huge, full breasts. Staring down at him, Roll expected some timid, uncertain answer from him, but instead he embraced her huge frame. He wrapped his arms around her wide waist and buried his face between her giant tits. His erection poked her in her cottage cheese thighs, dripping precum onto her silky skin. Roll stood there in shock as Rock nuzzled her giant tits.

“I love the new you! You're round and soft and you feel so good to rub against. Roll, I don’t know what’s wrong with me, I want to do all these things to you, I want to be inside you in everyway possible, its so confusing. Help me Roll, I love you!” Rock begged, uncertain of what he felt other then a need to be with Roll. His program had never prepared him for this.

Roll stared at her brother openly, her mind piecing together what was going on. Her brother was experiencing all these new emotions and had no idea how to handle them. He was just a kid in so many ways, so naïve about the world and unprepared for complex feelings. Whoever showed him the path would be able to mold who he became in the future.

“I love you too and I’ll teach you everything you need to know about sex and how to treat a lady,” she promised and pulled Mega Man’s head from her breasts. He looked just like a little kid, looking for a mother to guide him. She’d be his mother for now and then he could make her into a real mother. Cupping his face, she leaned down and crushed her lips to him. Megaman didn’t know how to kiss, so he just let her take the lead. Her tongue forced its way into his mouth, sending saliva dripping into their mouths. Roll moaned, enjoying the first of many wet, sloppy kisses with her brother. She had a lot to teach him, but she had a feeling he would be a good learner.




*Flash Forward*
"Done and done." Roll sighed happily. She had just swept the last of the house dust outside. She could have just vacuumed like she had with the rest of the house, but if she did that, she wouldn't get an excuse to see her man.

Yes, even today she liked to silently watch Rock from a distance, as she enjoyed reliving the innocent time back before she told Rock her true feelings. After their first kiss, things quickly blossomed between the loving siblings. Not only did they have a first, second, and third time all on that same day, but soon they were a real couple, going on dates and spending nearly all of their time together. They already loved each other so much that it already seemed like they had been dating for months. Also, aside from Dr. Light, no one even questioned them dating, as most humans felt that incest didn't really apply to robots.

Roll had to hand it for herself, she had done a magnificent job in teaching Rock. Her new programming let her tell him exactly what she wanted and he always delivered, whether it be time for cuddling, a massage, or when she finally said she wanted anal sex for the first time. He was such a great boyfriend she always told herself, as he loved her with all his heart just like she did with him, wrote her poetry, and was always a gentleman towards her. He'd kiss Roll's ass even if she wasn't sleeping with him...which she would never do, since she thought that would just be insane.

Of course everything wasn't always about her. Soon she was doing just as many things for Rock as well. The first time he discovered the joys of a blow job, he nearly shut down from hormonal overload. She even joined him on missions now, as her abundant fat not only defended her against most projectiles, thus making her mass changing ability even more useful, but she could now deliver the final blow to the robot master by sitting on them. No matter what though, Rock and Roll always pleased each other, just by being together, or when he filled her womb with so much cum it might burst.

Speaking of which, Roll rubbed her now even larger belly as it stretched out her white apron. As the sunlight shined upon her, Rock finally looked her way and the way her body seemed to glow in the light made her appear to be a cherubic angel. Of course, this so called angel gave him very suggestive smile once they met eye to eye, which made Rock drop what he was doing as his crotch plate suddenly felt tight.



“Faster! Harder! Stronger!” Roll screamed as Rock plowed her pussy. She was lying on her side, one fat drumstick leg over Rock’s shoulder as he pounded away at her sloppy, hot cunt. He had had one hand on her hips, digging into the fat until his fingers disappeared. His other had went around to play with her ass. He would rub her thick, large ass cheeks and then slip them between the buns, teasing her asshole. Roll let out a loud cry as he wiggled her thumb up her sphincter and touched her rectum. Ass play during sex always made her cum like a freight train.

She felt her climax coming on fast and violently, making her huge, blubbery body shake as she brought herself against him, his thrusts making her fat jiggle. She gripped her breasts with her sausage like fingers and screamed through gritted teeth as her her body shook and her pussy tightened around his dick.

“Almost there,” Rock said as he felt his love about to cum. He increased his pace rapidly, the wet sounds of him fucking her resounding throughout the room. She felt an orgasm about to hit her body as he increased his pace. Rock pushed himself into her violently, crushing his body into her meaty legs. He ground his hips against her as his climax overcame him fast, his hot seed splashing into her cunt. Roll screamed as she felt his cum fill her, a familiar feeling that never got old. He pushed into her a few more times before withdrawing his cock.

“Think….We….Woke the kids?” Mega Man gasped out as he crawled towards Roll’s wide, round belly. Everything was bigger about her then when they had started, but her belly had grown the most, partially because two tiny robots were being constructed inside Roll’s womb. She was pregnant.

“Why don’t you check for yourself?” Roll suggested as she rubbed her recently fucked crotch. Unlike humans, her womb was accessible to her lover to watch the children get constructed. There were being built piece by piece inside of her womb, able to communicate and think even though their programming wasn’t complete.

“I’ll check on them later, right now, I want to cuddle,” Rock said as he crawled right beside his love and draped her arm over him. Roll rolled her eyes, cuddling was just him humping her fatty body all day long, which wasn’t the worst thing. She rolled over on top of Mega Man covering him with her fatty body. He could handle her weight just fine, he’d been under it a hundred times.

Roll had her man, had her family, and everything she ever wanted, and when the boy and girl in her womb came out, she’d have two new lovers. She was already screwing her brother, why not her kids as well?
