After the success of last Monday, I thought I'd had a setback on Saturday. My wife was at work, and I thought Anna and Paul would let me watch them again. Instead of that, when it was their "bedtime" they went upstairs instead of fucking on the sofa. Anna gave me a smile as they went upstairs together, so after a minute or so I followed them, my heart thumping with excitement as I climbed every step. But when I got to the guest bedroom, I found the door closed. I stood there, listening for every sound. I heard him say something like: "come on wear it - I want to see you on the bed in it". And when I heard the first creak of the mattress I couldn't stand it any longer. I crept onto the terrace, and climbed in through a small window leading to the shower room. I could just about see enough through the crack of the door. She was by now lying on the bed dressed in a nun's habit! And he was standing over her masturbating his cock. He opened up her black gown and started rubbing and nuzzling between her legs. It was an amazing sight. Had they done this deliberately to tease me......we were both now masturbating over the same sight. The same girl.
