The thing with watching the neighbors as I masturbated at our aligned bedroom windows continuued. Some nights it was just he and I standing at the windows m***********, sometimes she would be m*********** him, sometimes she would drop to her knees and s*** him, and most weekends he would eventually bend her over and f*** her, her hands braced on their windowsill as they both watched me stroking. She was never exposed, always in a nightie. But one Saturday evenjng she was standing there in her nightie as he stood behind her, and as I slow stroked with her watching me, he slipped the straps off her shoulders and bared her to the waist, her breasts visible. I nearly shot off immediately, seeing her smile when she saw my knees nearly buckle as I fought to hold on. With the tightly packed houses there were was less than ten feet between our houses. He stood behind her fondling her breasts, they were talking but I could not read their lips. Eventually he slipped the nightie off her completely and I was m*********** furiously. He began to m********* her as we all stood there, and soon it was obvious she was having difficulty standing. He slid an arm around her waist and supported her as she braced her feet on their windowsill, and she began to m********* herself. It was more than I could take and I shot off, but managed to stay fairly erect and keep stroking as she went rigid and came as well. As soon as she had, she was on her knees ravenously sucking him off. It was a glorious three dimensional p*** show as zi managed to c** again, and there was no end in sight.
