When Kenichi, who is depressed after being dumped by his girlfriend, returns home, his aunt Makoto is there. It seems she will be staying for a while because the bathroom at home is broken. But right now, his head is full of the shock of being dumped. He leaves without much conversation and is taking a bath when Makoto comes in without knowing. Makoto, surprised to see Kenichi crying, washes his body to comfort him, and Kenichi gets an erection. Taking this as an apology, she cums him with fellatio, and the two cross the line.
