Gently teasing your little spot - Orgasm Denial

Slave has been good and earned some time out of chastity. But that doesn't mean he gets to cum.. I want to see if he can handle some gentle, slow, and sensual teasing. Without cumming of course.. I love to tease and deny my slaves, it's fun for me. Keeping them nice and horny by playing with his most sensitive little spot- His frenulum. He's been locked up for so long this little session is somewhere between bliss and torment. If he makes it without cumming, his reward will be a nice ruined orgasm next session. But for now it's back into his chastity cage and I'll call him again when it's time for his next teasing.
