KTB-079 The perverted sister has returned! Even if she's run dry, she won't stop fucking. A stupid last holiday with a sister who can't get enough and a brother who's always out.

The sister who used to take care of my sexual needs is back! Before she got married and left home, she always took care of her shut-in younger brother's sexual needs. She returned wearing a suit, exuding mature sex appeal just like old times... and she was still as lewd as ever! As soon as she came back, she sneaked away from Mom's watchful eyes to suck on my dick, swallowing the cum that splashed onto her suit with eager gulps! Even while I'm studying, she'd straddle my face without a word, or barge into the bathroom to suck on my cock. She'd even pretend to be close with me in front of Mom while thrusting my dick into her pussy! The sister who had learned all sorts of things in the city was overdeveloped and insatiable. Such a sperm-draining, fuck-happy sister and brother spend their last stupid holiday together.
