477GRMR-108 Human Observation: Making a naive female friend into a fuck buddy by raping her after she misses the last train while drinking at home

What was supposed to be an all-night drinking session with college friends turned into a mess when one person suddenly had to leave, leaving just a man and a woman. The guy seemed nice but got horny towards his drunk friend. He said he had something good for her, made her drink some suspicious stuff, and forced her into sex. I wanted to resist in my mind, but my body became unbelievably sensitive and was made addicted to dick.
