"My parents' house is so relaxing after all~♪" I went back to my parents' house for the first time in a while since I became a university student and I was relaxing at home when suddenly the doorbell rang. When I went to the front door, a beautiful woman I had never seen before was standing there!!! "Could it be Momoka-chan?! " "Yes! It's so mean to have forgotten about me!" I then found out that she was my childhood friend, Momoka Nishino. I was amazed at how cute she had become in such a short time and how she had grown in so many ways... "Sho-chan, you must be bored anyway, right? Let's watch a movie together at home now♪" I didn't have anything in particular to do, so I went with her to her house. When we started watching the movie, it had been a while since I'd been to her room and I was so worried about her that I couldn't concentrate on the movie at all...! What's more, the atmosphere became good... Momoka unexpectedly offered to have sex with me! ? We crossed the line and while we were having sex all day during the holidays, my old female friend, Ai Saejima, barged in and we all had sex...
