By name

You decide to rein in this idea before you develop that fetish...for now.

"Just Dick is fine. Maybe we'll try 'daddy' another time."

"Please feed me your semen Master Dick. Don't make me go to bed hungry."

You get into your bed with her and while you're still sitting on the edge, she gives you a handjob from behind, pressing her breasts against your back. You close your eyes and soon you feel her blowing you. Too soon. As in, she hasn't changed her position and you open your eyes to see your dick going into her arm through a hand-mouth that weirds you out.

"Woah woah woah, don't do that while you look human without being asked." She looks at you confused. "It can be off-putting to see new human body parts where they don't belong when you don't expect it. So use your regular mouth to blow me."

She perks back up when she gets her first authoritative order, moving into position in front of you, on her knees.

"Yes Master Dick."

She deepthroats immediately, and proceeds to move her head back and forth so quick and rough you can see the head of your cock making a bulge everytime she takes it to the base. She doesn't need to breath so she keeps this going for minutes without letting it out. You put off cumming by thinking another question to ask.

"Do you derive physical pleasure from sex or do you just act like you do for your partner? Give me a titfuck while you answer."

"I've heard women do both. But seriously, my entire membrane is an erogenous zone. You can rub me anywhere and I'll feel it. Besides that, I can orgasm whenever I want, though it's the best when I'm absorbing semen. I can't help climaxing when it becomes one with my body."

You decide to lift her up to find out how heavy she is. She weighs as much as she looks, pulling off that part of the facade flawlessly. She jumps up to help you and wraps her legs around your waist as she lowers herself onto your cock. You rip her top open to fully expose her tits, then have a thought about what you just did.

"Oh, these clothes are actually more of your body and I just tore it. Did that hurt?"

"I don't feel pain. I'm like a sponge, except the pieces that come off continue being parts of one individual, unless we want to reproduce. I explained that part."

As you talk, she continues to bounce her hips and take your cock to the cervix. It's definitely trying to get your load directly into the womb.

"So you could divide into two girls for a threesome and they're still of one mind however long or far separated?"

"Good idea. Anytime you want to try that, just ask. Ooh, I can feel you getting close. Cum deep inside me. I'll do anything, be anything for more of your cum."

You feel like you're well and truly emptying your balls to feed her the necessary dose of your cum. She orgasms around your cock as the head gets sucked by her thirsty womb. As you finish, there's a knock at your door. Figures with the noise.
