Jeff loved fucking his sister, but he felt something missing when fucking his girlfriend. Something just didn’t feel right. After saying goodbye to Sarah and (passionately) kissing his sister goodnight, he took a look at the Chronivac again.
Jeff decided to make his girlfriend a part of his family. Not by marrying her, but by making her his sibling. He selected his girlfriend and changed her entry so that her parents were the same as his parents, and he ticked the box labelled ‘reality change’. Jeff hit apply.
Suddenly, his girlfriend appeared next to him, sitting on the bed. However, she looked slightly different. Her hair, which was once a dark brown, was now blonde like his. Her breasts, which were a decent C-cup, were now an E-cup, bringing her in line with her new sister Natalie.
‘What do you think, Jeff?’ Sarah said, squeezing her tits between her arms. It seemed that she was still attracted to Jeff and Natalie, even though she was now their sibling.
Jeff groped her breasts, making her moan softly. He licked her nipples, and rubbed her pussy through her skirt. She grabbed his face and kissed him deeply, inserting her tongue into his mouth. After a few minutes of passionate making out, Sarah broke off the kiss.
‘Mom and dad are asleep and,’ she lifted up her skirt. ‘I’m not wearing panties,’ she said excitedly. They started making out again as Jeff took out his cock.
‘You’re so big Jeff,’ Sarah said, pressing her face against his warm cock. ‘Having sex with Natalie is great, but with you its even better.’ Jeff smiled, and effortlessly lifted his sister onto the bed, thanks to his Chronivac-enhanced muscles.
‘Okay, Mr. Muscles,’ Sarah said, giggling. She spread her legs wide; her pussy was soaking wet. Jeff inserted his cock into his sister, eliciting a satisfied moan from her. She began to rub her clit as Jeff fucked her.
Not even a minute passed before Sarah orgasmed from her brother’s huge cock. Jeff kept fucking her, and his new sister’s moans became louder and louder.
There was a knock on the bedroom door. Jeff was so horny that he didn’t stop fucking his sister even when there was the potential of being caught.
The door opened. Luckily, it was just Natalie.
‘Can you two keep it down?’ She was rubbing her pussy through her clothes. ‘You gotta share that with me later, Jeff,’ she said, giving Jeff a wink.
Sarah orgasmed at least 3 more times before Jeff came, shooting load after load into his sister’s womb. After coming to her senses, Sarah got up. Jeff smacked her ass as she left, and she gave him a seductive look as she closed the door. He really loved his sisters.
