Minerva sat at her desk, answering letters into the wee hours of the morning. She could hear soft snores coming from her bedroom and smiled to herself - it was always a comfort knowing that there was someone waiting for her, who completely loved and understood her.
She looked at the softly chiming clock on the wall and internally sighed - 1 am. She wouldn't want to stay up much later, as there was a meeting with the Heads of Hogwarts at 10am, but there was a lot of paperwork to do...
She heard a rustling of sheets and a stop to the adorable snores and glanced up, seeing a sleepy Hermione in a short nightgown bracing herself on the doorway of their main room.
"Darling... are you coming to bed soon? Though you might be invincible in the public eye, I know you need your sleep before that meeting tomorrow."
Hermione yawned and scrunched up her nose when she stepped out into the bright light of the room, and came to sit in front of Minerva on her desk. Her nightgown rose up as she gently sat and Minerva's eyes were instantly drawn to the expanse of pale skin before her.
Minerva placed her quill to the side and folded the letter she was writing hastily before standing up and quickly capturing Hermione's lips in hers, feeling her love grin into their kiss before reciprocating. They took their time in the kiss, feeling the push and pull of their emotions before Hermione took initiative and laid herself back onto the desk, pulling a more than willing Minerva down onto her while not releasing her from their kiss.
Minerva braced an arm beside Hermione and used the other to drag her fingers down the path of her love's curves, pausing on the curve of bosom and a hip bone before reaching the edge of her nightgown and slowly inching her hand upwards until she found the place where thigh met hip, and she caressed it. Hermione broke away from Minerva's lips and let her hips thrust upward as she moaned in the back of her throat. Minerva stood up fully and took Hermione's hand as her love's eyes completely darkened, seeing Minerva breathing heavily and her bun looking disheveled as stray hairs hung around her face.
"My dear... I believe our bedroom awaits..."
Minerva took off her outer robes as she stepped in the direction of their room, leaving her in a smoky green chemise, and undid her bun, letting her hair fall in soft waves around her face and down her back as Hermione sat up and bit her lip. Only one mentally insane would let this opportunity go, right?
