Letting go of her blushing, stunned sister, Nibiki let Ranma walk up to his lover to talk over what they were going to do. The reluctant couple looked between themselves and quickly moved to the corner of the room and turned their back to Nibiki to whisper among themselves about how they were going to deal with the horny eighteen year old demanding they join her for a threesome.

“I always thought Nibiki was greedy, I never knew she was such a pervert. Makes me rethink all those naughty pictures she took of me in my girl form,” Ranma muttered and shook his head in disbelief over what was happening. He expected Nibiki to pimp him out to other people, not ask him to whore himself out to her. He wasn’t going to argue that the thought of pounding Nibiki flat was a compelling idea, but he wasn’t going to do that if it meant hurting Akane. He had urges, but he refused to satisfy them if it hurt Akane. He may be a jerk some times but he wasn’t the kind of guy the screws his fiancée’s sister, at least not without her joining in.

“Maybe we can offer ourselves as food instead? You’re telling me I taste great all the time, right Akane? Akane?” Ranma looked into Akane’s eyes and saw her lost in thought, her mind a million miles away. Ranma reached over to shake her, but before he could lay a hand on her she snapped back into reality and took a deep breath before muttering softly.

“I think we should agree to what Nibiki wants.”

Akane looked gingerly at Ranma as his eyes bugged out at her sudden shift in disposition. Akane had been almost murderous when Nibiki suggested they have sex together and now she was saying they should do it, it boggled Ranma’s mind. Lowering her head, Akane sighed and hoped Ranma just agreed without asking why she was ready to fuck her sister. Truth was she wasn’t, but she didn’t see anyway out of this. Her sister always got what she wanted, be it toys when they were growing up, clothes when they become teens or the best people to eat as of lately. Akane knew her sister wasn’t going to drop it and if a threesome got her off her back and gave back her peace of mind she’d do it. Akane knew she had a temper, but she wasn’t stupid, she knew her sister too well. She’d have sex with her and then never speak of any of this again. The thing that bothered her the most was that it felt like the cowards way out. A tiny part of her noted how much Ranma was going to enjoy this and felt good about that. She found some pleasure in knowing he was going to have two women today all to himself, every man’s dream.

Strong, warm hands clasped Akane’s shoulder’s and she looked up into Ranma’s kind, sparkling blue eyes. “Only if you’re okay with it.” He smiled at her, knowing that this was tough for her to do without needing to hear the details. She returned the smile and Ranma felt his heart melt. Akane had one sexy body, but her smile was the cutest he had ever seen. He felt the urge to kiss her and leaned in to meet her with the biggest, most romantic kiss he could muster, but paused when he heard a loud cough coming from across the room.

“So I trust you’ve reached an agreement?” Nibiki seemed to think that they would have decided to agree because as they had been huddled in the corner she had undressed and was now lying across the bed, her massive breasts resting across her arms. Her hips had widened slightly since changing her diet to people, giving her a more bubble butt and smooth waist, but the mass was in her breasts that were bigger then her head. Akane and Ranma stared as they pressed into Nibiki’s arm, overflowing in her tiny hands as she lightly rubbed them. Akane had nice tits, but these were monstrous, the nipples alone were as thick as a strand of rope. Realizing that they had both agreed to have sex with this overly busty minx, Ranma and Akane wondered if they were going to fast. They had both been virgins only a couple days ago.

“Yes, but you have to promise that once we do this you won’t force us to have sex with you again,” Akane growled.

“I won’t force you,” Nibiki purred and sat up, her breasts bobbing as she moved. “Now strip.”
