Father-in-Law

This afternoon I walked in on my father-in-law getting fucked in the ass. He was wearing a wig and makeup, lingerie, stockings and heels. I stood quietly outside the door and watched in shocked amazement as he thrashed and moaned. I didn't know the man, but his cock was beautiful, thick and cut. Dad was getting his sissy ass pounded and loving it. Soon the guy plunged deep into my father-in-law's ass and came inside him with jolting thrusts. It was such a shock that I quickly retreated down the stairs out the door and down the street to my car. It was a lot to process and I sat with a raging hard-on with the car running. I sat for a while thinking "what the fuck did I just see?" Eventually I put the car in gear and drove home when I received a text: "I saw you in the doorway. Can we talk?".
