I was driving home late last night and as usual passed by my in-law's home. Parked in the driveway was the parish priest's car. Thinking something was wrong I parked my car next to his and made my way to the door. I passed by an open bedroom window and heard some curious sounds, if you know what I mean. I went up to the window and was stunned to see my macho father-in-law on all fours getting fucked in the ass by Father Murray. He was really putting the wood to him. I watched for a while and was further amazed when he suddenly pulled out and shoved his cock into dad's mouth. My father-in-law swallowed his cum and then they kissed passionately. Stunned and amazed I took a quick picture with my phone then hurried to my car and drove home.
