[Cy hasn't gone to put the blindfold over him yet, so he remains in that transitory moment, waiting with his eyes closed, at any moment able to open them and say stop. "Hades." It is the closest Sasuke has felt himself come to that safeword, that guaranteed exit, in a while between them — and genjutsu provides another layer of security on top of the foundation of their trust.

So he listens instead of allowing fear to take him out, a certain skittishness toward this act managed by the gentle, careful way Cy introduces the experience. His muscles are tense, and he almost jolts away from Cy's warm palm when it caresses his breast, but soon that tension builds into a pleasant shiver that spreads all across his chest. Nerves feel fire-lit, hot — this time he does struggle when that hand applies greater pressure to his lower belly, massaging the soft skin and bringing sharp awareness to the urgent need he's denied. He hears himself make a quiet sound, a whimper that sounds almost wounded on Cy's knuckles before his mouth is relieved and free again. A tongue licks after the stroke across his lower lip, kittenish.]

Yes. [But he needs to say more.] ... I'm afraid of it, but not because I believe it will be a bad experience. I know I'm not less in control.

[Now he just pushes his cheek into Cy's hand, rubbing against the damp silk affectionately.]

I trust you, and I want to try.
