My personal sperm doner thought he had it easy with me just riding him casually After I removed the condom and start squeezing and slapping his balls, making it a hell for him not to cum, he understood why I tied him down. Easy orgasms for me, pain and agony for him I put him on all 4, with locked hands and feet, and I gave him a reach-around handjob while I was handling his full balls in such way they would have no choice but to deliver all of their milk. His only option was to sit tight and get milked like a dog
