"Since your mouth is currently occupied I'll allow you to simply nod on if you are ready for your first anal experience." Ginny nodded vigorously and then moaned around the plug in her mouth as she felt the tip enter into her ass. The vibration function was not yet in play but it felt exquisite. She had imagined it would free painful but having an anal plug in her ass for six hours had prepared her. Ginny was going to ask her Mistress if she could wear a plug every day. She wandered how big she could get used to wearing. Her mind came back to the anal sex when she felt Hermione's thighs against her ass. The toy was now completely in her ass and she felt full. She nearly came on the first full thrust. After a few minutes she felt the vibration turned on and whined again. She was so close to her first orgasm at the hands of her Mistress and it was from anal sex.
