Looking for a small set of hentai images from a recent /b/ or /h/ thread. They were basically instructions on different sex positions, with a orange-ish haired girl and a shota. IIRC the first position was some sort of a "leg-lock", where the girl was standing on her toes with spread legs, and the boy laid under her.
Oh, and she held one of his legs up. The caption said something like "you can squeeze your thigh and calf together to regulate his thrusts, either to stop him from cumming too early or to tease him a little bit."
