Hermione smiled at Luna. It felt so good that she didn't want to move. She thought that she could stay inside her all night. Though, she was sure she would get aroused again before too long.
Absently, she wondered if she could actually do it again. Her cock twitched at the idea and she groaned.
"Merlin, I am sore," she confessed with a breathy chuckle.
Gently, she slid out of Luna and started to disentangle herself. "I hope you were serious about wanting to help me with my experimentations," Hermione said softly as she started to gather her clothes.
She tried to push away the feelings of awkwardness but it was hard.
