会社の後輩ミズキと付き合うことになった。ショッピングしたり、ご飯食べたり楽しい時間を過ごした。そんな時に取引先から1本のホームパーティの誘い電話が。断ることができずにミズキを連れて向かうことに…そこには、鼻息の荒いスケベじじいたちが待ってた。僕は、最低だと思いながらもミズキをそこに一人置いてその場を去ってしまう。再度呼び出されてホテルに戻ると、そこには楽しそうにオヤジと生ハメ中出ししているミヅキがいた！！！社員デビューから2本目で中出し解禁！！

I started dating Mizuki, a junior colleague at work. We went shopping, ate meals, and had a great time. Then I got a call from a client inviting me to a house party. I couldn't refuse, so I took Mizuki with me… and there, a bunch of lecherous old men were waiting. I felt horrible, but I left Mizuki there alone and went away. I was called back to the hotel, and there I found Mizuki happily having unprotected sex with one of the old men, with him cumming inside her!!! Cumming inside her is now allowed after only two sessions since her debut as an employee!!!
