My friend (Khalid 23M) who is a senior at office have very bad intention on my didi (Shagun 25F). It started when he once came to our flat and didi offerd him glass of water. She bend in front of him and as soon as she left he started saying things like - abe teri behen ka to pink h mza as jyega.

He almost regular rubs his D in front of me talking about didi and since last 2 days he comes to our flat when didi isn't here and asks for her bra panties and puts it inside his shorts. He lives nearby only and since my parents aren't here rn and it's just me and my di he is saying he will come home in night. I am really afraid what he will do. Any suggestions? I don't know how I feel. He makes me feel like a cuck.
