We woke at around seven pm, Jaq was walking around the apartment with just her panties on. 

I noticed the guy in the apartment opposite watching as Jaq's tits bounced around. Of course, I mentioned this to Jaq, she decided to give him a little show.

Against the full-length window she pressed her tits against it. Hand in panties she rubbed her now enlarged clitty. We could clearly see the guy furiously wanking, a few minutes later he shot a huge load all up the window. We watched as he cleaned it up before his wife came into the room.
