No Mercy Edging and Teasing - Standing Spread Eagle

I blindfolded my slave and chained him standing and spread eagle to my bondage bed so he could not escape. i then teased his erect cock by grinding it with my latex ass before spiking his body with my sharp wartenburg wheel. this little bitch has sensitive nipples so naturally i teased and played with them while mercilessly edging his cock. as a professional male slave body inspector and anatomy expert, i know all the special spots of the penis. i felt a little artistic so i got out my paintbrush and started working on his scrotal raphe before moving along the penile raphe up to the frenulum. when i could sense he was close to cumming, i would stop, slap and squeeze his cock to prevent his orgasm before continuing to mercilessly edge him...
