Less awesome was apparently what finishing alone would be. Rin could understand that from what she gathered of the male perspective. Still, she'd been invited to no fun, and thus it would be sad for her regardless. Beyond that information was the knowledge that the lad had almost finished earlier. Rin knew he'd been watching her, but was left to wonder exactly what he'd seen in her normal routine that counted enough to have the lad masturbating outside the bathroom door. Some things, were obviously not meant for women to understand though, "Oh, just admitting that pretty freely. Feeling comfy~" she asked almost rhetorically while watching the lad crack his neck and stretch his shoulders. He had a full body of muscle, not just abs, which was interesting to see from this angle. He was definitely a physical specimen without being something outrageous. It made her wonder how often he hit the gym, whatever the case she didn't get around to asking.
No instead a simple conversation was being had about her setup for their current outing. A few extra steps had been taken if only to ensure they had time to right themselves before they got caught doing anything and had a good cover for any inconsistencies in their night. "Yep, it also ties back into given potentials so we can't be overly questioned even if we're found downstairs taking a break. Otou-san would think nothing of me, scouring for a late night snack while complaining about comp or anything like that~" she said. All normal lies were fully in play. "Oh? I was distracting you was I? What about when I was in the bath, was that just for safety?" she asked in a teasing manner. All bases were covered. A condom was in play... sad as it was, she'd be lying if she said she'd not considered the curiosity and potential around condom-less sex. Still, as the person who would bear the brunt of pregnancy she wasn't willing to take such a risk. Perhaps it'd be worth it at some point to see a doctor and get birth control since her partner was so close and readily available. It'd also likely be easier to hide than condom wrappers and the like. But soon enough her wrist was grabbed and she and he were moving towards the tub as he questioned the 'deal' of today. "I hadn't considered all the options if I am being honest. I did offer you a hug though, wanna cuddle in the tub for a while, Onii-chan?~" she offered. Though in this case, cuddling involved his dick being buried in her core while he sat in the water, surely this counted. Besides, they'd never managed a fully nude experience before, it'd definitely be worth it. Still since the condom was in her occupied hand, the one caught by the wrist, her other would be found trailing down his abdomen towards his cock, she might as well offer him a hand to start with.
