ARM-952 She Calls Herself A Seductress, So Why Is She Getting Turned On When She's Trying To Tempt Me?

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!
