Tell him how you feel. You have a right to refuse to do anything that makes you feel uncomfortable and he should respect that. It sounds like you are talking about sex. In no case should a father-in law have sex with his daughter-in-law, it's just wrong. Adult Role-play generally is something romantic couples do; children role play but it is different for them - they are trying to figure who does what and why.
If he is asking you to treat him as the sex he is dressed as, if you choose to be around him, then you need to honor his request. There are times when you might need time to adjust and go in little steps, so tell him. But be willing to give just as much as receive when it comes to acceptance. He isn't going to change BUT he can willing to meet you in the middle. IF it has nothing to do with sex then he has every right to do what he wants (legally) in his home. If you don't like it - you lose out.
What you do and talk about with him when you two are alone depends on how comfortable you are. He should never pressure you into doing or saying something that you are not comfortable with.

Both phrases are correct, but the usage slightly differs. "Comfortable doing" is typically used when referring to a specific action or task, while "comfortable with doing" is more commonly used when referring to a general situation or concept. For example, "I am comfortable doing public speaking" vs. "I am comfortable with public speaking."

Touch him gently on his hands, and near his pelvis (if you're comfortable doing that). That should get the job done.
Talk about it until you both are comfortable
Only if you feel comfortable...don't let him rush you into doing anything you do not feel completely at ease doing.
At your age it is completely up to you whether you should let him. You are old enough to take responsibility and you should know yourself what you are comfortable with. If you are comfortable with this guy doing that, then it is your decision to let him do so or not.
I am much more comfortable now, thank you.
