[Chimeda] Mado wo Watareba -Otonari-san wa Onanii Chuudokujo- (Comic Magnum Vol.161) [BSN]

Night-shift worker Atsushi has one ritual for unwinding—stroking out a load the second he gets home—until a shocked glance through his window reveals his neighbor Michiru staring back, just as hopelessly hooked on the same daily habit. What starts as mutual voyeurism across a narrow gap of apartments spirals into exhibitionism-fueled obsession, with the big-breasted, glasses-wearing addict barging into his place to worship his big penis with sloppy deepthroat slurping before offering up her plush, sweat-drenched ass for round after round of raw, nakadashi-draining sex. By the time he's groaning that she'll never let him sleep, Chimeda's squirting-soaked romp has turned two facing windows into the most dangerous doorway in the building.
