A butt plug with a tail.

You pull a metal butt plug out of the box and show it to Jane. Attached to the end of the plug is some fur which resembles a fox's tail, and Jane seems to become very excited about her present as her eyes light up with joy when you show her the gift. But, as she reaches for it, you slap her hand away and pinch her nipples as a warning to remember her place.

"Remember, that this is punishment," you say, sternly. "Now, turn around! Make those tits kiss the floor and lift your ass up in the air."

Jane nods obediently and turns around, lowering her chest and laying her head to the ground. She then eagerly stretches her ass towards you, which gives you easy access to her holes. You spit on the plug and then place it against her asshole and start pushing it inside her. You are slow and careful, but Jane is very sensitive from a lifetime of use. She gasps and whimpers continuously until the new toys widest point disappears into her with a slight pop, and only the tail is still visible. For her part, Jane exhales in pure relief.

"Good pet," you say, praising her while rubbing your slaves belly. "Was that so hard? Was it too much for a 'little ****' like you?"

"No, Master," gasps Jane. "I will gladly do everything you ask of me."

"Then show me how happy you are and wag with the tail!" you order, "wag like a good dog, and stop using human language! You are not human."

Jane barks and whines in agreement like a dog. Then, she wiggles her ass in order to move the tail. You smile, pleased with her so far, and reach for the bowl Jane always eats from. This time, however, you actually want her to do it this way. Into the bowl you pour a can of stew that you just have to heat up in the microwave. It's not the best breakfast, but it's easy to prepare and Jane can eat it from the bowl without using flatware.

Jane barks happily and bounces a bit as you put the bowl in front of her. She immediately starts to eat on all fours and you eat too, but you sit at the table like a person and not on the floor. When Jane is finished, she approaches your side with her mouth completely slathered with gravy. So much so that you have to clean her off with a wet cloth, and Jane practically purrs in pleasure as you clean her. After she is clean again, you turn around to leave the kitchen; but Jane bumps against your leg and whines, clearly begging for your attention. You sigh and kneel beside her, first caressing her back and then her belly and breasts.

Jane moans and rolls onto her back. Once there, she pulls her arms and legs in to her sides to offer you better access to all her most sensitive areas. Teasing her further, you play with her wet clit for only a few seconds, then return to caressing her body. Jane is now panting and wiggling as happy as can be as you rub her belly with one hand and gently massage her breast. Seeing all this, you realize that you have been doing things wrong for the last few years. Since you took her in, you had tried continuously to teach her to be more human instead of accepting her as she is; and she truly seems to be happy as your pet.

"Good girl," you praise Jane while fondling her neck. "Who is my good little pet ****? Yes, it's you! You know what, ****? Since you are being such a good pet, I think you deserve a little reward."
