Erotic Footjob Ends in Ballbusting

I order my slave to lick my dirty feet spotless, before granting him the rare honor of a footjob. With plenty of oil, I glide over his cock and play with him using my soles while giving him a clear warning that this is his only chance for relief, otherwise absolute chastity will follow. However, since mere pampering quickly becomes too boring for me, I switch to a more painful method. I use the slipperiness of the oil to flatten his balls under my feet and deliver twenty extremely hard kicks directly to his private parts. While he has to take this treatment, I amuse myself with his reaction and show him that I love kicking his balls way more than giving him a footjob. Clip language is German
