I was text her one day about something. Wife was at work. Sent pic to sil with text that was clearly for her sister(wife). Waited a little while teen texted my apologies for the mistake. It definitely changed things between us. She is always giving me a look and once walked by while I wad changing in my bedroom with the door cracked. She stared for way too long but left right before I pulled my dick out to shack it at her. I definitely won't miss that opportunity again if it comes back around
