Butt

You can hardly imagine how good it'll feel to insert a warm, prehensile appendage up your behind. Ceasing the teasing, you slowly, very slowly inch the thick, silky smooth tail to your bum.

Sophie: "Hnnhh! UuuuUUuu, that's good... Gotta take it slower or I'll pass out any second."

Your tail takes true to its analogous usage and stiffens almost exactly like an erection. But now that your tail is wedged in well enough, all of the thrashing and spasming won't dislodge it anymore.

Sophie: "G-g-g-gyyyaa! Ah! AH!"

The intense stimulation leads your tail to quiver further, burying it ever deeper. For a while, you're locked in a feedback loop of pleasure as your tail spelunks your reaches. The action only dies down a few minutes after you run out of tail.

Sophie: "Huah... ha... F-f-fuck that's real good. Gawd... I could deal with this more often. I should just do this every day. All day every day, that is."

Reluctantly, you heave yourself up from under your sodden sheets, tail still firmly in your ass. You stretch for a bit and relish in the still-ongoing mini vibrations caressing your spine. But you still have a life to live and having a permanent resident like that would be a little inconveniencing.

But, trying to pry your tail away from its snug hole proves more difficult than picking a brick out of a wall with tweezers. Applying any meaningful **** onto it just makes it harden again, tugging your intestines along.

Sophie: "Well fuck me."
