New keep sake

"Bend over the bath and show me your asses." He ordered.

All three did quickly.

"Relax. This may sting but it will be worth it." He warned.

That had all of his slaves on edge.

Daphne was the first. She squeeked as she felt like something was being wrote on her left ass cheek. But it stung too. Like a bunch of bee stings. It didn’t take to long then the pain was gone.

"Don't move until I've finished with all of you." Harry ordered the Slytherin.

She did turn her head slightly and saw Hermione bite her tongue as he cast the same spell on her ass.

Hermione felt the stinging and her logical mind made a connection. But she wasn’t going to say anything until she was certain. When the stinging stopped she heard Luna squeek.

Luna didn't care what Harry was doing to her. She knew he would be careful with his property and she trusted him. But did squeeze Hermiones hand until he finished.

"All done girls. Hoop out and look in the mirrors."

The three did and were stunned at the sight. He had placed a magical tattoo on all their asses in the same place.

Potter.

He had marked them as his.

"Master...I love it!" Luna said happily.

Hermione and Daphne didn't show the same level of enthusiasm. Sure they were his for life but now they had a very clear sign of his ownership now.

"Dont worry girls. I can charm them to disappear when I take you to some clothing free beaches."

He already had plans for that. Sirius had a private island and he was going to take them there one day. Spend a few weeks and have them be nude the whole time. Except for their collars of course.

That made them more comfortable but now all three knew they had to be even more vigilante in the showers. They may just have to only bathe in the prefect room with each other from now on.

"Alright girls let go."

They all dressed and followed Harry out the room.
