High school boy sexually abused by his girlfriend's father

The high school student said that he drank a lot of alcohol and was afraid, so he did not resist... Oh, you little bottom~

(Note: The term "小受受" is often used in a teasing or affectionate manner in certain contexts, but it can be sensitive. It's translated here as "little bottom" which is a more direct term in English. Adjustments may be needed based on context and audience.)
