My friends decided to give me a spanking for my 16th birthday. They held me up in the air by my arms and legs and lowered my pants and underware to exposed my butt. Some joker came up and pulled them down past my knees while I was being spanked. Utterly humiliating because there some girls there having a great time looking at my penis hanging out undreneith me. I don't even dare look at any of them in the face.
