ARM-952 "Self-proclaimed Seductress Sister" keeps teasing me for some reason, and she seems to be getting turned on herself.

Alone with a lovely older sister... I can't help but expect H developments! But... for some reason, my sister looks restless. A boy who wants to feel good is supposed to be lifted up by her experienced sister with her proud technique, but... she feels touched by her body, and she gives a thick fellatio without intending to tease her. Damn, it's very suspicious. Maybe she's actually a masochist, but she's playing the role of "temptation sister" for you!
