If there was a woman who really got pregnant with his child, it would be Iris, because she was the last person he had been intimate with, but both of them knew how highly impossible it was.
They had not been intimate since Iris went through her first heat and it was months ago, if she was really pregnant, she would be showing by now.
Because of what happened to him, sex with Cane would always be very rough and raw, as he couldn't control himself once he got aroused and Aria knew that. If it was not for her advances all the time, Cane and her wouldn't have had sex as much as they did, since Cane didn't do it all the time with Iris.
He was very careful with his mate. Thankfully, whenever he was with her, it was the peace he craved the most from her, not the thought of getting pleasure from her, especially after he learned what she had gone through, there was no way, in his conscience, Cane would want her to revive such trauma.
