Painting a picture

I’ve been hooking up with this guys on and off for about a year and a half now. We are back on again. He likes to flirt and talk dirty when he’s in a playful mood. The other day he said he needs a picture so he can stop staring so before I left him I left him with one sentence to paint him a picture for next time. Kind of something to keep on his mind. It went over amazingly!! Unfortunately I’m not that creative with these one liners. I need some ideas please
