We were at my parents' house, in the bedroom I lived in as a child and teenager. We were in bed, and he was kneeling over me, masturbating fast. I watched his hand moving on his cock. I could tell from his breathing how he was close to coming.
"I want you to come on my tits," I said. "I want you to come all over me. I want your come to go wherever it goes. I want it on my face."
Immediately he was ejaculating on me. I felt his come spurting fast and hard on my face, so warm, and then felt it dripping onto my tits.
I was so happy. "Your come sprayed on my face," I said. I moved his hand to the semen on my face so he could feel it. "That was the hottest thing ever."
Later I told him how it was in this very room that I masturbated as a kid and teenager, wishing for him.
