Guiding my non-related sister in her first masturbation and ejaculation experience in an anime setting

In this steamy anime, I take on the role of a loving older brother guiding my innocent, non-related sister through her first foray into self-pleasure. With a mischievous grin, I encourage her to explore her sexuality, leading her to the bathroom where she's about to learn the ropes. Watching her delicate hand grasp her soft, hairless pussy, I'm eager to take things further. I gently remove her bikini top, revealing her ample bosom, before guiding her to touch herself intimately. As she becomes more confident, I join her, using my tongue to lick her wet folds, setting the stage for her first climax. The sight of her petite body writhing in ecstasy is enough to drive any man wild, and I'm no exception. After her initial release, I continue to pleasure her, this time with my eager cock, filling her up with my hot load, marking her first creampie. This is a tantalizing tale of first-time exploration and intense pleasure, sure to leave you breathless.
