Today is a cosplay photoshoot with my favorite, close brother. Usually, he doesn't talk about anything lewd and only says funny things, but today he's holding his smartphone and snapping pictures of my crotch non-stop! Tsubasa-chan, who completely trusts her brother by blood, gradually gets escalated into posing lewdly as demanded by her brother, and is half-forcibly led into raw intercourse with internal ejaculation.
