Drenched With Sin, the Body Demands to Interwine

Synopsis

Every time his tongue touches my wet, hidden place, my entire body is raided and numbed with ecstacy. We entwine our bodies over and over, while we fall into disorder, in each others' sweat. "Mai" lost her mother at an young age, and began living with Ken. As the two grow up, they begin to see each other in a sexual light, and ultimately cross the line. "I can't be become a hindrance for Ken..." With that thought, Mai makes up her mind to marry another person... "Just a little more, please..." Even though they know that it is wrong, the two begin to spiral down into the ecstatic world that they were forbidden to step into. (Source: Manga Reborn)
