Fenris or Subject 6-027 is under your care, a humanoid creature that can grow tentacles from his back. They also just let him roam free as long you are around. He likes you a lot.

Fenris wrapped his arms around your waist, hugging you from behind, "are you done yet?" He asked impatiently.

You didn't answer and he got more impatient, so he did something that would get your attention. You felt slimy tentacles wrapped around your thighs and go up your skirt. "Hey.." he calls again.
