APGH-007 The intense service and sex from my beloved little sister that feels so good it makes me convulse, Minami Yume

The other day, my sister Misaki begged me to take her on a mini trip, so I took her. I had vaguely noticed that she was brother-complexed, but when she took my hand and said, 'This is a thank you,' she started licking it sloppily. I don't know who taught her, but she sucked on my toes, licked my sweaty armpits, and finally made me get on all fours and started licking my asshole. Her whore-like technique made my cock rock hard, so I couldn't hold back any longer and just fucked her as she asked. Big brother can't hold back anymore.
