For science!

"Oh shit, sorry dad," Jacob hastily apologised his eyes locked on the older woman's pale expanse of cleavage, "I guess I got a little distracted, but we definitely know I'm changing you now, right?"

"That much seems clear son," his Milf father agreed holding up her hands to inspect their manicured nails, "I won't embarrass you by asking why you're thinking of attractive older women instead of your dear old dad, but perhaps you could try again and really focus this time?"

She managed to keep her tone light, but there was no disguising the slight tremor in her voice or the way her cheeks flushed pink.

If Jacob didn't know better, he'd have thought it was excitement. But no, that couldn't be it. Despite appearances, this was his father, the man who'd once organised a letter writing campaign over the local cinema showing R rated movies. If Jacob didn't have the evidence of his own existence and that of his sisters, he'd have said the old man was basically a monk.

No, it must just be embarrassment, Jacob decided. Getting turned into a slutty cheerleader and then a hot soccer mom would be enough to make anyone blush. The right thing to do would be to at least try and turn her back into a him.

Regretfully, he gave Mrs Spencer's body one last lingering look before summoning the mental image of his father. He concentrates as hard as he can until...

Nothing, the duplicate Mrs Spencer, remained stubbornly distractingly present. But why? Jacob wondered why couldn't he reverse the transformation, what was different now?

Slowly an idea dawned on him. Before he hadn't just been thinking about Mrs Spencer or the nameless cheerleader before, he'd been fantasising. He'd imagined them wanting him, pleasing him...

"I wonder what she'd look like naked?" He thought, turning the full **** of his horny mind on the former man, "even hotter, I bet! She'd bend over, show me her pussy dripping wet and beg for my hard young cock. And she wouldn't sound like a gross old man, She'd sound sexy, her voice all soft and husky..."

"Eep!"

A distinctly feminine squeak of surprise interrupted Jacob's train of thought, and he looks up to see his dad still a woman and now totally naked apart from a pair of sexy black stockings.

"Jacob, what the heck?" she whimpers, "Why am I naked? Stop this now. At least look away."

She makes an effort to cover herself, but instead finds herself grabbing at her tits and flaunting them for her watching son.
