Caius didn't drain her.
He never would.
Before long, he was pulling away from her neck and pressing their lips together again and they moved against each other in a manner that caused Lea's erect nipples to rub against Caius's chest, causing her to groan in delight.
Caius unlocked her legs from around his waist and the moment her feet hit the ground, Lea was grabbing the tree trunk with both her hands and shaking her ass in Caius's face. He took handfuls of the wonderful flesh, his tongue trailing across his canines and his Vampire-red eyes gleaming as he angled his dick to the entrance of her pussy and pushed in.
His pelvis hit her ass to a delightful spank sound as his cock struck against the entrance of her womb. Lea's tongue wagged as she cried out in pleasure and when Caius pulled back to begin thrusting, she pushed against him to get him right back in.
And thus began their hard-hitting thrusts.
