You knew about your boyfriend’s… more animalistic nature.
He told you the story of how a lion almost killed him (well, technically it did since he was dead for like 3 minutes) but then somehow came back. He said that he got some kind of a potion or something that brought him back to life but you weren’t really that particular about details. He survived and that’s what matters.
Anyway, back to your him being a literal animal.
Sergei was like a beast. His senses were enhanced and so was literally everything in his body. It helped him during his hunts and not only then… cause it sure did show in bed. You often ended up with red marks on your back, thighs and even arms due to how tightly he was grabbing and holding you, sinking his fingers in your flesh like an animal ready to tear its prey apart. Not gonna lie, you were kinda digging it.
However, what you didn’t appreciate that much was him dragging you outside at the crack of dawn for a morning walk. If it was a normal walk, just around the nearest paths you wouldn’t mind it that much. But no, he had to drag you to the wilderness, a few miles away from his house. Not that there was anything else around — he was living in the middle of nowhere, all of the wild animals running freely as if they were domesticated (they weren’t and you almost got your hand bit off when you thought you could pet a panther).
“Come on, sweetheart. Don’t slack off!” He called out as you were almost crawling behind him. His stamina was no joke.
