通过课程的最好方法是吮吸你饥渴的老师的鸡巴，直到他快乐地高潮并操你达到高潮

My teacher is a horny guy, I always see how he watches me carefully, I'm not doing well in his subject so it occurs to me that I can pass it if I can get him to fuck my ass and fall in love with me. That's why I seduce him, I suck his cock and we fuck until we orgasm.
