Ok. So we are currently ch 50 in the book, and i believe it is ch 69 is when heat starts and he goes into Graysons roo., ch 70 is when it happens.
Now, this author has a lot of nonconsent, so it happens in every novel I've read but kiss me if you can. Busy an FYI!
And for anyone who thinks otherwise...it's not gentle with how much Grayson tried to avoid it. I actually felt so bad for Grayson:
He was flaccid, told Dane to stop several times, including screaming, and jumped out of the way. In the end, Dane spread pheromones to induce rut, they exchanged physical punches and kicks until grayson couldn't fight anymore.
But doesn’t he apologize to Grayson afterwards? In the novel, despite it being Grayson (person he hates) he realizes what he did to him and takes accountability for it. But then its not just Dane who’s at fault, but also Grayson for keeping Dane at the mansion unwillingly and forcing him to like him through sharing the same space. Gahh they stress me out man
Oh! And for the person who said 'if he hadn't trapped him ' remember Dane Kidnapped him before that. So no blame game.
It was a rough scene of course until Grayson started to enjoy the sex, but Dane knew he attacked him, and Grayson was shaken by it.
And to person who came from 1st of Summers...year the season closer gutted me too.

All of you who think dayne is just the sweetest and kindest guy... He's not.
Spoiler below....
He grapes Grayson
