Demons bite each other - sometimes brutally - during the act. Sesshomaru refrains from introducing her to that part - his "biting" ends up being soft kisses along her slender shoulders. She might feel the impression of his fangs, but nothing more.

The way she wraps around him is perfect and he speeds up his thrusts, driving them relentlessly onward. Gold eyes meet her dark eyes and he wraps her in his arms. If they begin to float...slightly...that's nothing to worry about. Demons bite and tumble and join again and again through the skies.
