I was supposed to have sex with my wife to make up after a fight, but... I ended up having an accident with my mother-in-law! A beautiful waistline, a tight, firm peach butt, and a beautiful anal hole deep inside. I vigorously ejaculated inside her vagina, which was tighter than usual! When I tried to apologize to my wife again, I looked at her face... "M-mother-in-law!?" She was pale and apologized profusely, but the shock of the instant penetration turned on my beautiful mother-in-law, and she attacked me, and we went into the second round!
