He seduces her without his special ability.

Bill is feeling confident.
He wants to see how he can do *before* he uses the Master Cock.

"Your picture did not do you justice," he says.
Shay blushes and thanks him.
"I love seeing you in that. I wonder if you look even more incredible without it."

Shay smiles and reaches behind her back.
Showing years of practice, she unhooks the bra and holds it in place.

Bill smiles as she builds anticipation- letting her seduce him- before she takes it off and tosses it aside.

Bill knows not to leave a MILF waiting.
"I was right. You look amazing. I love your tits- so firm and beautiful."
She blushes and speaks up.
"You don't know how firm they are just yet."
"That's true. First..."

Bill takes off his shirt, impressing her with his defined torso.
I mean, what is the point of giving you a Master Cock without a hot body to go with it.

He covers the distance and puts his hand on her tits.
She grabs his wrists and lets him fondle them.
She leans in and kisses him, which he answers back.

After a long kiss and grope, he asks for the next step, running his hands down her sides to her hips.
Shay nods and slides them off.
He eyes her lovely pussy and smiles.

Bill guides her to the couch and has her sit down.
He leans in, joining her on the couch and sucks on her tits.

Shay loves this.
Shay needs this.

Bill finishes- for now- and tells her spread her legs for him.
She does so and he begins to lick her pussy...

"Oh my."
She wasn't expecting this.

Bill was soon ready to play his trump card...
