antorgasm
instead of seeing a good-looking potential sexual mate nude. It involves accidentally seeing an old relative, in-law, or strange aged person nude showing stretch marks, wrinkles, birthmarks, body hair and drooping body parts.
I just had an antorgasm, when I accidentally walked into the unlocked bathroom and saw your aunt Millie changing into her large bathing suit-I don't think I can eat again for at least a week.
