This is a Vlog masturbation support video recording the strange relationship between me and Mayuki, the older sister next door.
We aren't lovers... but we aren't just neighbors either. It's more like a convenient fuck buddy arrangement.
"There's a cockroach!"
"I got scared watching a horror video..."
She makes up random excuses to barge into my room and gets erotic on her own, but then she plays dirty by asking "What do you want to do?" at the crucial moment.
She even took a spare key without permission, so she can come and go whenever she wants... I can't even masturbate in peace anymore.
Only when she's in the mood to get erotic does she come over to flirt and play, getting turned on by my flustered reactions and acting like a nympho.
She's a whimsical masturbation support older sister who comes to borrow my cock with the same casual vibe as asking to borrow some soy sauce.
She changes her pattern every time, so I never get bored.
Truthfully, I want her to be my girlfriend, but it would be a waste to break this relationship, so I think I'll enjoy this masturbation support life for a while longer.
