I gave my young busty stepmother to my classmate

I skip school and stay home. One day, my dad remarried to Hitomi, a beautiful woman with very big breasts. That was the catalyst for me to change my daily life. However, her classmates become aroused by her stepmother's huge O-cup breasts. I was bullied, and in order to live a cheerful school life, I handed out my stepmother to them. My stepmother was gang-raped in front of me, and I felt it just by touching my breasts, and was creampied many times by the intense hip thrust of an adolescent boy.
