I asked her if she was with a man yet but she said she was still a virgin. She then asked me to teach her about sex as she knew I would be patient wit... her and she wouldn't be afraid. I agreed as I began to help undress her pert little body. As I undid her jean cut-offs, she lifted her sweet little ass off the couch and I slid them down. She had on these little white cotton bikini panties with small red hearts on them. I could see a wet spot in the crotch from her excitement. She pulled her. She giggled and admired the pink fur that was poking through her thigh high socks. She wiggled her toes and flipped over, clearly enjoying what was happening to her, and presented her butt to her "Audience." Her shorts quickly split and shredded by both her expanding hips and her long tail. Her ears became pointed and her mouth pushed out into a cute muzzle. She drove one of her new paw fingers into her wet pussy, making everyone in the room blush. She panted and increased pace, moaning louder. I dipped the tip of my middle finger in there and was surprised at the lubrication already present. I looked back at Tracy's face, her eyes were droopy and her mouth was half open. She was very aroused; her breath was short and shallow. If I kept it up much longer, she would no doubt have an orgasm right then and there. She had totally lost control to her body. I was tempted to take her all the way, but I knew that if I did I would be taking a huge chance in front of mom considering how loud. WHACK! WHACK! WHACK! her ass starting to bleed now and her screams growing louder and more desperate. After a few more strokes she started sobbing and said „ok, I’ll do it, just please stop! Could you please fuck me in my ass?“WHACK! „Mean it, bitch!“„Please, fuck me in the ass!“WHACK! „Is that what you call begging?“WHACK! „Ouch!!! Please, let me stick your dick in my ass and fuck you. Please!!“ „Ok, that sound better! I hope you really mean it, though!“ With that I cut her bonds and sat down.
