Aoi and his girlfriend have been dating for a while. Lately, she has been showing signs of wanting to get married but Aoi is not ready yet. So he tries to avoid going home by taking on extra work from his colleague to stay at the office. Aizawa notices this and invites Aoi out for drinks and a bite to eat. Caught up in the moment, Aoi misses the last train. Since Aizawa's place is nearby, she invites him to stay at her place for the night. When they arrive at her place, Aizawa immediately changes out of her work clothes into something more revealing, with no underwear! Every time she bends over, Aoi gets to admire her beautiful skin and breasts. It seems like Aizawa knows that Aoi is sneakily watching her, but she not only doesn't cover up but also entices him. Aoi can't resist the angelic beauty and deadly charm of Aizawa. They make love throughout the night, in every corner of that enclosed room with only two people immersed in this lust...
