"Children, please," said Claire, "there is one thing I didn't tell him, because I was going to leave."

"You were going to leave?" Exclaimed Clara.

"I was. But I won't. I'll explain later. Or tomorrow. I have a reason to stay. I have two reasons to stay." She beamed at both of them. Clara and Mike wore the same smile back.

"Fine. Don't think about it again. So what was the thing?"

Claire leaned over to whisper in her ear. Clara reddened as she spoke.

"Oh. Yes. Yes. Yep. Yes."

Clara sprang to her feet, grabbed Mike's hand, and dragged him to the bedroom. Claire followed. Clara turned to Mike, and moved close. "Are you really okay with this? You won't change your mind?"

In answer, Mike kissed her, long and deep. "I'm always here for you. Both of you." Clara pressed against him, and he kissed down to her neck. She clutched him tightly, releasing just enough to let him undo her robe, and pull off his trousers, leaving them naked and ready. They kissed again, and Mike saw Claire sit at the side of the bed, legs parted, and hand working busily.

Mike picked his sister up, her legs wrapping around him, and he lowered them both to the bed. He kissed her deeply, bowing his head to capture a stiff nipple, all the while angling his hips to find just the right spot. He slid inside his sister's impossibly wet pussy, hearing the high squeak he had come to love. She kissed him, hard, bucking back against him. He realised now that he should have known immediately that it wasn't Claire in that closet; Clara moved so differently, her own, wonderful person. He looked into her eyes and saw the fire blazing there, stared deep into her soul as he thrust deep into her. He was distracted by a very wet noise to one side.

Claire was three fingers deep in herself, and panting hard. "Don't fucking stop," she said. "This is too hot."

Mike didn't need to be told again. He thrust hard into Clara, and rolled onto the bed, spinning her around to land on top of him. His hands found her breasts, cupping and caressing as she started to ride him. He arced his head over to Claire, pulling at her, kissing her leg. He pulled more, insistently, until she got the idea. She straddled him, facing Clara, her eyes still glued to his cock buried in his sister. He saw no more as she sat down, grinding her wetness into his mouth. Mike's tongue went to work, licking and sucking, as Clara's hot wetness clamped tightly around him.

Mike's hands supported Claire's ass as she sat on his face, and he paused licking and sucking as he heard Clara's whimpers. Heard her muffled whimpers. He pushed up, half-lifting Claire just enough to see her kissing Clara deeply, tongues lashing against one another. He tried hard not to cum, and distracted himself by licking Claire's clit, doubling and redoubling his attack until she screamed as she came. A muffled scream. He tried not to dwell on it, fucking harder and harder into Clara. As she clamped down on him with her own squeak he could hold back no longer, and pumped spurt after spurt deep into his sister.

The tension flooded out of the three of them. Claire fell into his left arm, Clara into his right. He kissed Clara first, then Claire. "I never knew you were into women," he said.

"I think I'm just into Clara."

"Yeah, she seems to have that effect." Claire nuzzled into him, whispering promises of love. He looked over to his sister, already half asleep, with a smile on her face happier than any he had ever seen.

"I really do love you," he said.

"Me or Claire?" said Clara.

"Yes."

In a few seconds they burst out in giggles. In a few minutes, they turned into moans.
