Back to the present: He starts investigating

Tom put down his phone, clearly uncertain of his feelings towards Jen. A woman can't have dicks! It's probably something else!

Still he keeps thinking about it: His mom with a big fat cock. The image however doesn't displease him, it's quite the opposite. Somewhere deep in his heart, he wished Jen really had one. But up till now there has been zero evidence that she indeed has penis.

He went upstairs, stood right in front of her bedroom. The first place to start investigating is of course her bedroom.
