the day i first went to my friend's house. riku falls in love with his friend's mother, rin. the intense sensuality emanating from her plump, big-breasted body is incomparable to his classmates. riku, unable to say that he's interested in his friend's mother, leaves the room with a flimsy excuse and goes to see how rin is doing with high spirits. it's okay if i can't talk. i just want to be near the woman i admire. at the end of the quietly opened door, i glimpse rin's unexpected lewd state.
