Oneshot
It's a good oneshot imo. There is both pegging and PIV. I personally don't like pegging very much, but this one had both so I don't mind it!
I like their dynamic. Asteff is a tsundere (plus slightly bratty puppy sub) and Belinda is a tease. Love love this type of couple!! Anyway it was a good read for smut.
