Sexting Sisters Bf

Imagine you're settling in to bed after a long day at work. Your wife has to get up early, so you're calling it a bit sooner than usual. But just as you're about to clock out, your phone vibrates… It's her sister, sending you slutty pictures from the next room! The first is a somewhat innocent selfie. Then another vibration. This time… is that her nipple? Another vibration. She's rubbing her wet pussy through her panties! With Kiara on the other side of the wall masturbating, what do you do? Do you risk getting out of bed and waking your wife? Or do you pretend this is a bad dream and go to sleep?
