I am in Bangalore (29M). I recently found a guy and a girl on Grindr who are into cuckold. There is certain story behind them. I am bit unsure this and a girl is not actually a couple and they are brothers and sisters. There is a story behind all this. Essentially the brother is looking for people who can sleep with his sister.

I am a bit concerned about my safety. They live in a good neighbourhood and live with their parents. They get the place occasionally and thats when they can calling me. I am unsure whether to proceed with it or not?
