I have a fetish about secretly being watched while I masturbate. I have just never found an opportunity, until now. This happened just last night. I live in an apartment complex, on the bottom floor. Recently, I've noticed a very attractive woman, about my age, living in the building behind me, on the top floor. She has a kid, about two years old, but I've never noticed a man in her life. Well, one night I was feeling extremely naughty, and went over and slipped a note under her door. The note said 'naughty show at midnight, apt 17...flick light on and off once to acknowledge.'
As midnight grew closer, I got even more excited. At around 11:55, I went into my bedroom, turned on the nightstand lamp, and opened the blinds. I waited about eight minutes until I finally saw the light flicker, and in that brief instant, I could tell she was nude! This got me super excited and slowly started to strip down to nothing. After I got my clothes off, I layed down on the bed, in perfect view of her window, and started stroking my throbbing cock. I kept looking over to her window, knowing that she was watching. After about 20 min of stroking, I couldn't hold it anymore. I blew my load all over my stomach and chest. After I got up I went over to the window and looked over at hers, and I rubbed my cum all over myself and licked my finger. She closed her blinds and turned her lights back on. I assumed she was probably jilling herself to a wonderful orgasm!
That night I received a note under MY door! It said, 'Awesome show last night! I was so horny, I was fingering my soaking pussy the whole time! I would like to return the favor tonight. Same time?' OOOOOOHHHHH I can't wait!!!
