Bind Rose and begin the lecture

You pick up another length of rope from the floor, grinning at the two girls as you measure it in your hands.

"So good of you bitches to come prepared," you growl, snapping the rope between your hands and looking at Rose, who whimpers and squirms excitedly as you approach her. Without being asked, she holds her bound wrists out to you her eyes flaring with excitement. You grin at her and loop the rope in your hands through her bound wrists then pull the rope over the arm of the couch and tie it to the legs. She kneels on the couch, her arms extended, her ass in the air as she whimpers in a frenzy, wriggling at you.

Lashed to her chair, Margot is making high pitched whining noises as she watches, looking at you with desperation. You give her a sneering grin and drop your pants, kicking them off your feet as you throw Rose's skirt up on to her back, giving her a smack on the ass and making her squeal through the gag of her panties. You stand between them, watching them, your cock stiffening as you look at the two helpless teens and begin to tutor them.

"In some species the male gathers a harem of bitches. Controlling them, using them in turn. And the cuter the animal sometimes the more perverted they are," you laugh. "Those cute little sea otters that everyone loves, the ones that lie on their back and wash things on their chest, you've probably seen videos, right?" The girls nod at you, making muffled sounds around their gags, both of them looking puzzled but excited.

"Well, they're degenerates. The male will grab a female and bite her nose to hold her while he fucks her. Sometimes he drowns her while he fucks her and he keeps fucking her corpse. And even that doesn't satisfy him. He'll grab another female and treat her the same way. And another and another and another until he's sated, his balls empty. The lucky bitches survive with wombs full of pups. The others...well, they're not so lucky." You sneer as you glance from one excited face to another.

"Let's see how lucky the two of you can be," you laugh coldly.
