Richard Castle was on to something but he wouldn't tell her what it was.
He knew she was somewhat predictable in her sexual drive.
He could tell now that she was horniest the days after her period, insatiable to be precise.
Then, the nights were exhausting enough without toys but now he'd been informed that she had bought a penis ring and love balls. That could be his death, if he actually came to wear the penis ring and gave up the control.
Not to rouse any misunderstandings here, he liked to be cuffed.
And he especially loved being cuffed to Beckett's bed.
He always had loved those control games. But with Kate these games became one of his favorites for sexual pleasure.
She would tease him, yes.
He would squirm, yes.
And she would watch him squirming and begging, yes.
It was almost an unbearable tension when she did that.
However, with Kate he then always came as intense as never before. None of his other girlfriends that tried playing control games with him had ever given him that much pleasure like Kate.
He knew he could trust her with this.
He knew she'd let him come.
With such a breaking force, he always had to spurt much more cum on those orgasms she gave him.
With such a violent force that sometimes he even fell unconscious temporarily.
He loved silent sex with her, lovemaking in its sweetest form, with lots of intense and deep kisses.
He loved loud sex with her, boisterous and horny, with lots of pants and screams, just piercing thrusts to fuck her into sexual nirvana.
He loved getting blowjobs from her, sweet and torturing, hot and rough.
He loved her submission when she was getting tormented with only soft touches, crying and begging for more.
He loved her dominance when she was riding him ecstatically.
He loved masturbating her to her peak with his fingers, listening to her quickening breaths.
He loved licking her into heights no one had even tried to give her before.
And he loved eating her out, sucking her into an explosion of fire and colors before her inner eyes.
He loved cuddling with her, without having sex at all.
Which one of those she might prefer tonight?
He hadn't asked her this because he knew this would be a night she was hungry for any kind of sex, greedy and voracious to get herself an orgasm.
He knew this was the time of the month she'd be just looking out for herself, not considering him.
But this was not important tonight.
