結婚間近のまりあは、正月に結婚の挨拶もかね婚約者の実家を訪れた。花嫁修業と称し一生懸命家事の手伝いも行い気立てよく過ごしていたが…。元薬剤師の義父に目をつけられ、婚約者が近くにいるのにコタツの中でこっそり特別に調合された強力媚薬をオマンコに塗りたくられ…。抵抗するもじわじわと滴るマン汁。義父のテクニカルな指マンにコタツよりも熱くなるアソコに抗えず連続絶頂。それからコタツ、押し入れ、夜こっそり旦那の横でも義父の媚薬手マンに溺れてしまい…。「指だけじゃなくてお義父さんのチンポほしいです…」結局汗だくぐちょぐちょになるまでヤリまくった3が日。

Maria, who was about to get married, visited her fiancé's family home for New Year's to pay her respects. She was being kind and helpful, diligently helping with household chores under the guise of bridal training, but… Her father-in-law, a former pharmacist, took notice of her, and even though her fiancé was nearby, he secretly smeared a specially formulated powerful aphrodisiac onto her pus under the kotatsu… She resisted, but her pus juices slowly began to drip. Her pus became hotter than the kotatsu from her father-in-law's skillful fingering, and she couldn't resist, experiencing multiple orgasms. After that, she was addicted to her father-in-law's aphrodisiac fingering under the kotatsu, in the closet, and secretly next to her husband at night… "I want more than just your fingers, I want your dick, Father-in-law…" In the end, they had sex non-stop for three days until they were drenched in sweat and dripping wet.
