There's a lot going on here. Aria and Sebastian are trying to navigate their very new sexual relationship with the secrets they are both carrying around. Sebastian is a caring lover, trying to give Aria what she needs and wants in the bedroom. It's great sex, and Aria is becoming attached to how Sebastian is with her. They've only been together a few days and things are moving at the speed of a freight train 
 I do ike the pacing of this series. It's held my interest and I fly through each installment. I don't mind moving quickly, but there something about the D/s relationship here that seems off to me because of it. It would have been nice to have a little more sexual tension in the relationship before they actually get to quadruple orgasm subspace. 
 But I do like this story, and I need to know more about what they are hiding.
