the night guest
Ever since the death of her husband, Mrs. Arakawa has run her inn alone. There's never been a guest the seasoned innkeeper couldn't handle... but she's never had to host a hungry oni. It'll take all her wits and wiles to survive the night in his service--or else she may find herself in his mouth.
The Night Guest is a spin-off from The Dragon Double Feature 2, but takes place before it and can be read as a stand-alone story. This book features an older woman seducing a younger man, size difference, mommy dom, cunnilingus, praise, teaching, cowgirl position, and mating press.
