敏感な足をくすぐり、お尻を叩きまくります

Today I ordered him to lie on his stomach and give me his feet to tickle. I sit on his calves so he can't dodge his feet and start tickling. My hands and nails on his sensitive feet really tickle a lot and he can't stand it. To keep him in position, I spank his bottom so he learns to endure the tickling.
