You need to find out.

She gasps softly as you kiss her inner thighs. Her eyes flutter shut, her hands gripping the sheets.

"I..."

"Is it because I'm your son?" You ask, teasing her sex with your fingers. They rub across the fabric, making her gasp.

"O-Oh no... It's not that... I've always had this... this reaction to..." She blushes, her words trailing off into a sigh.

"Yeah? For some reason..." You take your fingers away from her panties, and much to your amusement, she unconsciously pushes her hips towards your hand. "... I'm not inclined to believe that."

You chuckle darkly, kissing her thigh again. The silky smooth skin sends shivers down your spine.

Katherine opens her mouth to speak, but you quickly press your finger against her slit, pushing the fabric aside to reveal her cunt.

You see the pink flesh within, glistening with her arousal. You dip your finger inside, finding the warm wetness of her sex.

"There is something else..." You keep thinking aloud, pleasuring her just enough to keep her on edge.

"Is it the wine...?" You wonder. "No, too easy... Is it my touch? Flattering as it might be, I don't think that's it either..."

You lean over her, pressing your lips against hers. A soft whimper escapes her throat as you kiss her. She kisses you back, moaning as you slip your tongue into her mouth.

Her taste is so different from yours. You want to savor it. You kiss her passionately, letting your tongue explore her mouth.

You grab a hold of her panties and rip them off from her. You stand back a little, admiring her dripping cunt for just an instant.

You lean in close, meeting lips with her once again.

"Mmmm!" Katherine moans, returning your kiss. You push your finger inside her, feeling her tight insides clench around it.

You watch her eyes widen in surprise, then roll back into her head. "Ahhhh!"
