Stefan doesn't know what is, but every time he makes love to Bonnie it seems to get even better. They have made love several times today already (on the sofa, the staircase, in the shower, and finally the bed), but it feels so good that he still wants more of her.
He tightens one arm around her while the other moves down to the small of her back. He begins to caress her there and Bonnie sleepily nuzzles her face into his chest. He smiles and shifts to move his erection away from her body so he doesn't wake her. They have all day tomorrow to make love.
