After going on a job I made a big deal about my balls hurting so my wife would call her nurse sister. Like a charm my plan works, and Jane comes over before her shift at the hospital. Luckily for me my wife had already left the house. So when Jane goes to take my pants down I hit her in the face with my fat cock, after a bit of trying to examine my balls she couldn’t take it anymore and needed to get my cock in her mouth. My plan has worked. Now she can't say no. I get to fuck my wife's sister until I cum deep in her pussy.
