Mommy comes into the room to find her son lying in bed. She announces she is going to do a penis inspection, as she’s been wondering if his penis is bigger than his father’s. She pulls down his trousers to begin the inspection, taking a ruler out to make the precise measurements. She is delighted that his penis is actually much bigger than his father’s, so to celebrate she begins to lick and suck it, with increasing vigour until he eventually explodes his cum all over her face.
