I walk in to see my step son (Dan) jerking off to my picture. I tell you it wouldn't be right if I didn't let you cum but the only way you can cum is if I give you instructions on how to stroke your cock. I notice that you are staring at my smartwatch and figure out exactly what your fetish is. When you are close I take over stroking your cock and tell you to cum when I get to 0. I start at 20 begging for a big facial until you blow a huge load all over my face.
