Completely immobile. He cant take it anymore but I get the second orgasm at the end

First I tied his arms behind his back. Then I completely mummified him and fixed him to the end of the bed. I stopped him from moving and stuffed his mouth with a smelly sock so that he couldn't be so loud anymore ;) Afterwards I teased him, hit his balls and tickled him. After he was close to orgasm I refused the orgasm. When he did come, I continued until I finally milked the second orgasm out of him ;)
