By intruding her mind

You finally get your dick out of Gilian pussy and order "Take your clothes off."

Lisa, since it looks like its her name, frown but looks even more surprised than angered when her hands start to move for her and unbuckle her belt and remove her clothes one by one. She open and shut her mouth, unable to say anything. You smile at her. She's as hot as her mother, but without the maturity and with more sparkle in her. Like you suspected, she also has a pretty big chest. Not as big as what you gave her mother, but far more than what she had before you took her of her. Otherwise, she looks pretty much like a younger, slightly shorter, slightly thinner version of your ****.

You slap Gilian's butt and order her "Leave the rest to me and go make me a sandwich. Bring one for your daughter too. And don't come back until I call you."

She obediently get up and walk away. "Yes, Master." she answers, though she has a worried look on her face.

"Don't worry, everything will turn out for the better." you assure her, to which she answer by a happy smile. Lisa looks at her in shock the whole time, not letting her eyes go away from her mother and those big tits of her.

You sit on the bed, facing the naked teenager, your raging hard-on still standing proudly.

"You can talk, now, but only to answer my question sincerely. Do you think I'm attractive?"

She tries to bite her lips, but answers "Yes."

"Do you find your mother attractive?"

She looks away and blush, but says "Yes." again.

"Keeps looking at me. Are you a virgin?"

She decides to fix her eyes on your dick rather than facing your stare, and her face turn even redder. "No."

"Did you have sex with boys or girls."

"Both." she can't help but answer.

"What did you like more?"

You see her fighting internally, but she loses every time. "Girls."

"Look, we don't need to fight. You're sexually attracted to me, and to your mother. You don't see anything wrong with my relationship with her and simply wants to be part of it. You're not afraid of my power and trust me entirely. You want to be my ****, just like your mother. And you're not ashamed of any of it, even though you won't talk about it to anybody else. Understood?"

She suddenly stop blushing. "Yes, Master?" she answers, but you still hear doubt in her voice.

"Not only do you want to be my **** and have sex with your mother and I, you also love it. You have no doubt that it's the best thing that could happen in your life."

"Yes, master!" this time, she's sincerely smiling.

"Now, suck my dick. And Gilian?" you scream "Come back! We'll eat later."
