My newlywed sister came to visit our parents' home, but for some reason she showed up in my room. Her expression was unusually serious. When I asked what was wrong, she confessed she was worried her husband found her a bad lover and was growing distant, so she begged me to help her practice. With no one else she could turn to, she pleaded with me. Caught completely off guard, I was stunned when she suddenly straddled me and turned me into her practice partner.
