Every day, I masturbate countless times like a self-pleasuring otaku. One day, my dad, who used to be quite the player, remarries a woman... essentially becoming my step-mom. And so begins our life together... As I'm going about my daily routine of jerking off the next morning, she walks right into my room! She sees my hard-on and says something unexpected: "If you just let me suck it, that would feel good." Though her intentions are questionable, I know she has plenty of experience thanks to being a former slut herself. So, against my better judgment, I find myself falling for her seductive teasing and semen-swallowing education!

毎日何度も欠かさずオナニーをしている自慰オタクのボク。ある日、元ヤリマンオーラが漏れ出ている親父の再婚相手の人…いわゆる義母ってやつだ。と同居生活が始まる…翌日～日課のマスタべをしていると呼んでもないのに義母が部屋に入ってくる…ボクのチンポを見て何を思ったか「舐めるだけならイイよ」甲斐性はないが精子だけはたくさんあるボク…元ヤリマン義母のおせっかい誘惑と精飲教育に心を入れ替える！
