Jake fled as soon as Sarah looked at him. He didn't know how long he had been frozen there, watching in a twisted mix of gut wrenching horror and unwanted arousal. He just knew he needed to escape from that room and the betrayal that had happened in it. He practically dove into his own room and slammed the door behind him. It was all he could do to just collapse and let the tears flow.

"What was that?" Kate suddenly shot up.
Sarah was about so say it was nothing when an idea to use this to her advantage came to her. She grinned as she feigned concern,
"It seems your brother came home and saw us. I think he was a bit surprised and went back to his room."
Kate paled, pleasant afterglow forgotten as fear gripped her at what her brother must have seen and how hurt he would be, "He saw us!? Oh my god, what do I tell him? He'll be crushed, I can barely believe I've done it myself. I need to go explain-"
Sarah interrupted her by embracing the confused girl, guiding Kate's babbling face once into the comforting valley of her tanned breasts. Kate stopped talking immediately and Sarah took a moment to make sure the blonde took a deep breath of her scent before speaking,
"There there, calm down, I'm sure he is just confused by what he saw and needs some time alone to process it. You said yourself that he's an understanding guy, I'm sure that if you give him a little time he will be happy that me and you have fallen for each other. I know I won't be tormenting him in school anymore."
Sarah knew that was bullshit of course, no one would be fine with their lesbian tormentor 'turning' and fucking their sister, but at the moment Kate wasn't thinking straight. She would probably latch onto the first comforting words thrown her way, which was exactly what was happening as she felt Kate beginning to nod to her words, so she continued on.
"Look, I know it's a bit 'unconventional' but it's what's happened... and do you really regret being with me?"
Kate shook her head. She had enjoyed her time with Sarah, even if she had been surprised at the start; she had never felt anything like it before. She didn't know if she was a 'lesbian' now, when before she had most definitely thought of herself as straight, but the feeling of Sarah's strong arms, musky scent and soft breasts just made her feel so safe and secure right now. Sarah was probably right and she should just let Jake have some time to compose himself.
Kate snuggled in closer and almost started in surprise as she realized that she was beginning to feel aroused by cuddling with the tanned girl, the unexpected heat building with each breath of Sarah's heady scent.
Sarah smirked with triumph as she felt the telltale feel of Sarah's nipples beginning to harden against her own body. She almost couldn't believe how easy it was proving to condition the girl to be a little lesbian femme; her kind motherly nature being a natural complement to Sarah's own brash butch personality. Sarah's own arousal peaked as she imagined the fully converted hot little femme dyke the blonde would be when she finished with her.
Kate gave a light squeal of surprise as Sarah pushed her back onto the bed...
*********
Jake was considering calling his parents, but knew it was an exercise in pointlessness; the pair of them traveled for work and generally spent more time traveling than at home. That was part of the reason why he and his sister were so close in the first place. What would he say anyway? 'My lesbian bully is fucking my sister and your daughter, please ask her to stop'. Short of physical violence that would definitely not help the situation he couldn't think of what he could actually do.
Maybe he could go talk to them? Clearly explain what he wanted. He had almost come close to calming down when he heard it, quiet moans that increased in volume.
Jake froze and listened.
As the minutes passed the moans rose and fell, and before long they became so loud Jake could identify them as belonging to Kate. It was Kate's voice mostly, sometimes he heard a deep throated moan that definitely belonged to Sarah, but for the most part it was his sister's cries.
Finally, there was a scream of pleasure, and then silence. He thought he heard some talking then, and maybe what could have been a sobbing sound but he didn't dare move from his spot to check. Then more talking that sounded distinctly like Sarah again. She almost sounded...comforting?
Then silence. It was a few hours of Jake sitting in frozen fear before he heard Kate's pleasured moans start up again. It was well into the evening by that point and the sounds continued well into the night as Jake struggled to ignore what was happening just through the wall. As much as it horrified him to even consider, Jake wondered if Sarah was trying to fuck his sister into submission.
The talking between the moans seemed to get shorter as the night wore on.
It was four in the morning by the time Jake collapsed bodily into unconsciousness, the moans of his sister and her butch tormentor continuing even then.
*********
As sunlight finally entered the room Sarah sat up and took a moment to appreciate her handiwork.
The sight of Kate's exhausted body, smeared with pussy juices, breasts heaving, was the single most erotic sight Sarah had ever seen. Kate's nipples formerly a delicate pink were now an angry red, where Sarah had sucked, pulled and licked at them with reckless abandon. All across Kate's delicate pale skin were angry red marks where Sarah had hungrily sucked the sweat from her body.
The innocent straight girl had been completely converted. Sarah knew she had taken her utterly, erasing the delicate straight girl in the process. She was a femme dyke now. Her cunt, breasts and tongue were entirely for female use now. She lovingly ran her hand over the girl's lower stomach, imagining the primed womb and ovaries within that were now meaningless, Kate was a being of raw lesbian sex now. Her body would be used only to serve hungry women.
Kate had so many things to learn. So far Sarah had been the one giving all the pleasure, but now Kate would learn how to eat pussy, as was her place as the femme in the relationship, Sarah fully intended for eating pussy to be a prime part of Kate's diet from now on. Kate's virginity was another topic of excitement for the tanned dyke. She had a ten inch strap on for exactly that purpose that would make any attempts by a man to use her pussy afterwards an exercise in futility. She could just imagine those big innocent blue eyes bulging when Sarah's big powerful hips drove into her.
Sarah was brought back to the present when Kate made a small sound of discontent at the loss of contact and heat when Sarah had sat up, and sleepily and reached out unconsciously toward her. Sarah obliged her sleepy lover and with a final satisfied lick of her cum soaked lips she collapsed on top of the blonde girl and fell into her own light sleep.
