Conditions said no, according to Atsushi. Rin understood that thought not innately. Wise, as she was more used to calling him, didn't turn her down, or rather hadn't so far, but that could be for various reasons, including the sort of thing she was already doing... like rubbing her hand along his dick. "Hai hai," she murmured while thinking about the nature of their new existence.
With all this access to each other, she couldn't have stopped herself from exploring a bit. Their interactions in general were kind of rushed, and that was fine, but that didn't mean she wasn't interested in something else. Right now, it seemed they were trading rushed work mode sex for... sketchy fantasy moments. A point was made by Atsushi about the normalcy of men in towels and she gave it a bit of thought... that was way more normal than a girl in a towel. Of course that idea was only further pushed around by the mentioned craziness of Atsushi's mother which made Rin's eyes widen just a bit. "I really don't envy you that part. Do you need a hug, Onii-chan?~" she asked in a teasing manner, while also blushing at her lack of thought. "Though it did kind of slip my mind that you could just be in a towel," she said while thinking there was nothing wrong with their current planning. "Long baths will give you wrinkles~' she teased, "But fine, I guess I'm going to fetch condoms and set up the secondary alibi then," she said as he moved around her. She was finally able to step out of the bathroom, though not without leaving that caddy in place in case of a need to explain why she was hanging around the bathroom in the first place. With that she headed for the stairs and up to her bedroom to fetch a condom and make sure her Switch was plugged in and making noise from their room. What else would she do, cast a casual wave towards places she figured there were cameras. While sparing herself no body movements at all... why would she, she was sure Atsushi, was watching.
