Aoi and his girlfriend have been dating for a while. Recently, she has been showing signs of wanting to get married, but Aoi is not ready yet. Therefore, he tries every means to avoid going home, taking on extra work from his colleagues to stay at the office. Aizawa noticed and invited Aoi out for some drinks along with a bit of food. Being caught up in eating and drinking, Aoi missed the last train. Since Aizawa's house is nearby, she invited him to stay over for a night. When they got home, Aizawa immediately took off her work clothes and put on something sheer, without a bra! Every time she bent down, Aoi got to admire her beautiful skin and breasts. It seemed that Aizawa knew Aoi was sneaking glances at her, but instead of covering up, she invited him in. Aoi couldn't resist Aizawa's angelic beauty and deadly allure. They made love all night long, everywhere in the closed room with just the two of them lost in their lust.
