人妻上司である宮西さんは、優しくて仕事ができて、しかも美人の憧れの存在。そんな宮西さんと地方出張する事になったが、ボクの予約ミスで1部屋しか取れていなくて相部屋する事に。ドキドキが止まらないボクに宮西さんは「旦那とは冷え切ってるし2人でイケナイ事する？」と体を密着させキスしてきた。ボクは婚約中だと言うと、「秘め事って興奮しない？」と完全に誘惑モードに突入。ボクもフル勃起して濃厚背徳不倫セックスへ！

My boss, Miyanishi, is a married woman, kind, competent at her job, and beautiful—a woman I really admire. I was scheduled to go on a business trip with her, but due to a booking mistake on my part, we only had one room, so we ended up sharing one. My heart was pounding, and Miyanishi pressed her body against mine and kissed me, saying, "My relationship with my husband is cold, so how about we do something naughty together?" When I told her I was engaged, she went into full seductive mode, saying, "Doesn't the idea of a secret excite you?" I was fully erect, and we proceeded to have intense, forbidden, adulterous sex!
