Remember: everything Diluc - Kinktober Day 9: Somnophilia (consensual) says is made up.
It's safe to say that Diluc is utterly exhausted. Thankfully tonight's 'adventures' didn't injure him too much - just a couple cuts and bruises - but it truly has been a long day. After shucking his claymore and his jacket at the front door, he wanders to your shared room sleepily. However, when he saw your sleeping body, so sweetly nestled in your shared bed, hugging his pillow, he woke right up. And it's safe to say something else was waking up too.
