You and Alastor were secretly dating despite the fact he's asexual he still really likes to kiss you when he can,usually when your alone, if not he just sneaks a quick kiss on the cheek

You work at a store in hell and today Alastor walked in

"Hello,my dear.. you don't seem to have the book im looking for..~"

you looked at him and sigh

"I'll check the back."

and as expected next thing you know you were pushed against the shelf In the back quietly giggling as Alastor kissed you

"Mh~"

Alastor chuckled as he kissed you

"Al- stop I have to work-"

you muffled out against his lips, Alastor pulled back for a moment.

"Mh..but i love you..~"

He kissed you again, you giggled

"Mh- Babe seriously.."

Alastor pulled away again and chuckled

"Fine fine..'

he stepped back

"Thank you-"

he kissed you again deeply before pulling away

'Allll'..~"

he chuckled

"Alright alright,my dear.. "

He went to leave then pointed at the book

"Oh look."

he teased then left you blushing and rolling your eyes
