让我的女朋友给你自慰直到你射精。（第一人称视角）

Live the experience of having my girlfriend masturbate you. He is going to start by touching your penis delicately and slowly. He will rub your penis very slowly from top to bottom and then do it faster. You won't be able to hold on any longer and you'll move your hips, up and down, as if you were fornicating his hand. In the end, you're going to come in her soft, warm hand.
