A smart girl transferred to my school. Her uniform at her previous school was sleeveless and her armpits were always exposed, so I couldn't help but look at her... One day, the transfer student said to me, "You're always looking at my armpits," which made me feel embarrassed, and then she said, "Let's study together at my place." While I was studying at the transfer student's house, she was braless and had her armpits fully exposed!! This was a total invitation!! When I attacked her while she was sleeping, she said, "If you want to have sex with me, you have to beat me in a mock exam." I studied hard, but the result was a crushing defeat. She was kind enough to say, "You worked hard, so let's have sex!" The voice of God! Please enjoy the youthful armpit story of a transfer student and a dropout.
