Chapter Text
"So Richard, has Kate ever told you about the time we had sex?” Meredith all but coos the question. Kate looks amused as Rick, in typical fashion, nearly spat out the sip of wine he just took.
“No! When? What? Woah!” After this response came out of his mouth, he grinned sheepishly at his ex-wife and his girlfriend. The two of them just laughed.
Kate knew Castle’s overactive imagination was going in about 50 different directions. She turned to Meredith, took her hand, and stood up. “What do you say, Meredith? Should we show him what we did? How I made you come a few times, and you paid me back? I think I have a few dildos here, maybe we can show him how we made each other come with them?”
Meredith got up gracefully, and looked at Rick as she nodded. She took one last sip of her wine, and let Kate lead the way. Castle was still sitting at the table, with his mouth hanging open slightly. Kate turned around, saw that he was just sitting there, and said, “Coming, Castle?” He shook off his shock, nodded his head yes, and followed the two of them through his office and into his bedroom. The two ladies laughed at Kate’s pun and his eagerness.
When the three of them were in the bedroom, Kate and Meredith turned to each other and kissed. Rick went over and sat in the chair that was by the side of the bed. He could feel his pants getting tighter by the second. He could hear the two of them moaning and could actually see their tongues as they kissed. He was so turned on by the thought of his ex-wife and his girlfriend fucking each other in the past and now in front of him. They were going to have sex on his bed! This was awesome.
Kate broke off the kiss with a “pop” and she stood back from Meredith. They nodded at each other and just started to undress themselves, as they had on that long ago night. Meredith was naked sooner and she climbed up on the bed, wiggling her ass at Kate and Richard. She laughed as she could imagine Richard’s face - that mixture of boyish charm and ruggedly handsome that had always made her want to get naked immediately. But she pushed those thoughts aside, as a naked Detective Kate Beckett was a hell of a lot closer – as in, right next to her on the bed. The memories of that evening with Kate came rushing back as Kate pushed her on her back and hovered over her. Kate had a thigh pressed up against Meredith’s pussy and Meredith couldn’t think any more as Kate ground it against her. Kate leaned down to kiss Meredith and she reached a hand up to pull on Kate’s breast. She gave it a twist and Kate groaned loudly. She responded by removing her leg from between Meredith’s legs and reaching down with her hand.
Somehow she managed to get her hand into Meredith’s pussy and she rubbed it. Now it was Meredith’s turn to groan and she let go of Kate’s nipple. Kate took advantage of this and she turned herself around. As she put her pussy on top of Meredith’s face, she put her hands on her pussy and spread it open. As Meredith started to lick her, Kate took her clit in her mouth and sucked on it. Meredith whimpers were a bit muffled as she was licking Kate.
Castle couldn’t believe he was watching this. He was sitting on a chair naked (he had undressed during a lull in the action) in his bedroom watching Kate and Meredith lick each other. Having had sex with both of them he could recognize that the two of them were getting very close to climaxing – and he knew he had a very hard cock he was stroking. But he wasn’t going to join in – he wanted to watch. Shortly after he and Kate had started dating, they had realized that they liked to watch each other – sometimes just masturbating, sometimes watching the homemade sex tapes, and on a few occasions, watching each other fucking someone else. The third option was his favorite, but it was the hardest to plan. So he was really happy Meredith had brought up the past.
But he shouldn’t be wasting time thinking about this; he should be watching them. Because he could see that Kate was no longer licking Meredith. Instead, she had two fingers inside her, and he could see her twisting her wrist. Then he heard her saying, “I remember I got you to squirt, Meredith. Do you think I can do it again? Rick, are you watching?” She turned her head, and saw that he was watching very closely. She grinned and returned to finger fucking Meredith. Meredith keened as her back arched, knocking Kate off her body. Kate rolled to the side, watching in amazement as she squirted her come everywhere.
Kate still hadn’t come, so she started to pull on her own nipples as she watched Meredith get herself under control. Meredith went up on her elbows and grinned at Kate. “Well, Kate, I guess I owe you again. You did give me the first orgasm that night too, if I remember. Let me pay you back,” and she slid across the bed to get her mouth on Kate’s pussy. She dove right in, flattening her tongue to swipe it across Kate’s slit. She licked up and down, and paid very special attention Kate’s clit.
“Oh fuck, Meredith! That feels amazing! I’m so fucking close, let me come,” Kate moaned as Meredith sucked on her clit, and then she went back to pulling on her own nipples. She was so close, but then Meredith stopped sucking on her. Kate whined as Meredith spread her legs, “Please! I’m so close!” Meredith teased her by kissing her right thigh and then her left. But she could see how frustrated Kate was getting, so she got closer to Kate’s pussy, and used the tip of her tongue like a small penis and jabbed it at Kate’s clit. Then she took her fingers and pinched it. And that gave Kate the release she wanted so badly, and she came with a shout.
Meredith sat up and grinned over at Rick. He had a hand on his cock, which was rock hard. “Rick, I guess you’re enjoying yourself! “ And then she saw that Kate seemed to be ready for more. “Kate, are you ready for more? I am!” Kate nodded, reached over to one of the bedside tables. She had long ago claimed it as hers, and she had some of her favorite toys and other sexual aids in it. As she rooted around in the drawer, her ass was a little too tempting for Meredith, who caressed a smooth globe. Then she moved her fingers from Kate’s ass to her asshole, which made Kate jump.
Castle had stopped stroking his cock. He didn’t want to come yet. But when Meredith started playing with Kate’s ass, his cock got even harder. It was starting to hurt so he knew he was going to have to find some release soon. He got up gingerly, and he saw Kate’s face as Meredith inserted a finger in her ass. He knew Kate loved having her ass played with during sex.
Kate stopped looking for a dildo; Meredith’s fingers in her ass felt wonderful. She moaned as Meredith put her other arm around her waist, and moved her back to the center of the bed. Kate had no coherent thoughts as Meredith moved her fingers in and out of her ass. She collapsed onto her stomach on the bed as she felt her climax building. Kate knew she just needed a little help to go over the edge, so she put her fingers on her clit and rubbed. It only took a few seconds, and she was wailing as she came. Meredith smiled as she watched Kate as she came down from her high. By now, Richard was now standing at the side of the bed, his wonderful cock hard and ready for action.
“So Richard, should we show Kate how we fucked that morning?” she said with a smirk.
