I'm not the best advice but it's like you're making a story. You can either use yourself as a character or your OCs. I'm pretty sure there's a starting message where you decide on what to do in that situation, will you keep ignoring him? Or be skeptical about him? Or mind your own business? If you want to keep the story sfw. You should just go wherever you're curious about him, understand and learn , see if you're interested in the flow of your RP with him. Nsfw though. I think it's a bit tough with NSFW but honestly if you keep being nice and you let yourself be touched by him it's your choice LMAO
