Now crawl over here. Stay on your knees, of course. The daylight from behind me should give me a nice, good view of your body. Don't worry, pet, nobody will be able to see you from the street through these sheer curtains. Or will they?
Both hands on your tits now. Feel your nipples through the fabric, and tease them with your fingers for five more minutes, or until you can raise a blush, whichever takes longer. The hornier you make yourself, the sooner you can move away from the window!
