Luna was surprised at the speed at which her pet impaled her on her thick cock, causing her to moan loudly as the pressure in her slit intensified by the vigorous pounding her pussy received. However she was frightened when a bit when Melissa violently came into her womb, making her question if she had taken her pill this morning. Luna instantly looked at her pet with angry tinge to her eyes, "Mango.............We have something to discuss dear." She remarked angrily, a scowl on her lips as she unclipped the leash and grabbed a handful of Melissa's hair. "I see that I made an error in judgement by handing you control. Do you realize that if I wasn't on the pill then I would have a lot of explaining to do to your father about why I became impregnated by you on the first night of our relationship."She stated to her pet in a stern demeaning tone. "Being a dominant means not only controlling your submissive, but also having control of yourself not to make it seem like your abusing the trust your submissive places in you. You did tell me you wished to fuck me dear, but you didn't have the self control to realize when you were about to cum and air on the side of caution by pulling out before shooting your load." She added, pulling her pet's face closer to her own. "Now then tell me why I shouldn't either lock your cock back up or get it fixed so this little problem doesn't arise ever again." She asked, indeed thinking that her pet might be better off with having her tubes tied if she didn't have it in her to control when she came. Their was no malice to her tone though, only firmness and hints of frustration and disappointment.
