I was at the ranch one weekend by myself when my mother-in-law showed up. My wife was at her friend's house and I THOUGHT she was going to spend the night there. My mother-in-law and I started drinking and after a bit she came on to me. I gave in and felt bad but Joan, my mother-in-law, was a very attractive woman so, I gave in and we started making out. About an hour later I was sucking her toes and making slow foreplay with her. As I came between her legs my wife walked in quietly behind me, took her mother's leg and spread her leg out. Very shocked I turned around to see my wife smiling at me and kneeling down she said let's eat mom's pussy. I was speechless and Joan spread her legs and her daughter started devouring her mother's pussy while I sucked her mother's toes and fingered her clit. After Joan came in her daughter's mouth my wife turned to me and said "My love will you please fuck my mother, I told her about the size of your cock and I set this whole thing up." We all fucked and sucked each other all weekend.
