We'll start with a talk

It was really only three turns before you were in the heart of the maze. That was probably for the best; from the moment you grabbed Bruno's arm, he had tensed up. Now back in his home, he visibly relaxes. Unfortunately, he also steps away from you, removing his bicep (that's as thick as your thigh) from your grasp. "Right, well. Did you want to help with our project? Or were you... planning to answer my, um, other questions?"

"Truth be told, I don't know about baby monsters. My earliest memory is being cut in half by a paladin in the name of some god or goddess. Probably Amari. I do know a lot about sex, though."

"No, I understand that process. It doesn't answer my question. Where did you and I come from? Who or what created us, and why?"

Those are... really big questions. You let a respectful handful of seconds pass as you both ponder them--Bruno far more deeply than you--then give your best answer to the last one. "Why? So we can have sex, obviously."

Bruno turns a red face down at you. "You-! That's not an answer!"

"It is to me," you say with a shrug. "I'm a succubus, and can only remain such as long as I have sex every day. If that's not a raison d'être, I don't know what is. So? Wanna?"

Bruno stares at you, stunned. "You're not taking this seriously, are you."

"Sorry. It's really hard to think serious when I'm horny. Mostly I've been thinking about what it would feel like to lean against those steel pecs." You bring one hand up and brush it across his bare chest, admiring the sculpted feel of the muscles under his hide.

That makes his trousers stir. A small bulge pushes up against the fabric. To your surprise, though, his thoughts go in a completely other direction with that. "Physical reaction. But why? What good does a sexual attraction to a demonkin do for a minotaur?"

"It keeps me alive and happy. Now, are you going to stop worrying about this long enough to bone me, or should I just gag you now and handle this myself?"
