The younger brother, who was ridiculed at school for being a virgin and felt depressed, had an older sister who said to him, "If you want... if you want... lose your virginity with me?? Even if it's someone like me, you'll hate it, right?" Such dreamlike words. Of course, the younger brother immediately took her up on her offer and started having sex! But the younger brother couldn't soften even after ejaculating multiple times; he was a superhuman stud. Then, continuous internal ejaculation 10 times in a row in front of his promiscuous older sister! The older sister becomes utterly exhausted from the intense full-power sex of a virgin.
