RCT-993 - Invisible Lesbian: Office Rampage 2

It feels like Aoi Rena turns invisible and just messes around with Erika Kitagawa, Madoka Hitomi, and Haruna Ikoma! Aoi Rena's excitement is hilarious, and it has a real comedic touch. Because of that, the lesbian sex scenes feel a bit less exciting, though the one with Erika Kitagawa wasn't bad. I don't really get the 'invisible' setting, though? Obviously she's unseen, but apparently she's unheard too, and unless she wants to be, she can't even be touched... wait, so she's just invisible? That's all it is!
