A long overdue OTK spanking

Description: My sub had not been to see me for a long time. as soon as i bade him over my knee, he managed to gain an erection that pressed against my fishnet tights and dug into my leg. he was enjoying it far too much so i stood him up and proceeded to birch and tawse him. i do not like erect penises digging in me. bit i suppose i should take it as a compliment
