A man who starts dating a childhood friend who is not particularly beautiful but has a great personality. As he begins to spend time at her house, her younger sister Akari returns home. Surprisingly, Akari has grown into a beautiful woman, making his heart race, but he pretends to treat her like a child. Akari suddenly says, "I'm better at this," and forcibly removes his pants, taking his member deep into her throat, performing self-imposed deepthroat fellatio. Overwhelmed by the pleasure, he can't hold back and ejaculates into her throat, with drool and a large amount of semen spilling from her mouth!
