[ONIN-092] My First Machine At first, I was afraid, because... - I was insanely squid with an accurate machine piston eating!

Eight curious women take on the challenge of the masturbation machine "Machine". Attach a big to the tip of a mechanical device, and when you turn on the switch, it becomes a piston robot that repeats the same operation precisely! When the girls are ready to apply plenty of lotion to the local area, they fearlessly insert the cyborg into the meat jar by themselves. At first, it was a slow movement, but it felt better and better, and gradually the speed of the machine increased and I climaxed.
