Kat cast a hammerspace spell on her reproductive system. Instantly, Dan felt a bit hungry, and told Kat so. Kat looked up at Sandy and cast a muscle control spell.
Sandy felt her body move without her telling it to. "Kat," she said, slightly scared, "What are you doing?"
Kat sat with her legs spread, Sandy's feet between them, "I'm doing what you said. You wanted to be closer to Dan."
Sandy had a feeling she knew what was about to happen, and couldn't tell if this turned her on more than it scared her. Kat then grabbed her feet and shoved them into her pussy. Dan immediately began to suck them in, pulling her all the way up to her ankles.
Kat magically opened her closet door, which was right in front of Sandy, to reveal a mirror. "Now you can see how close you're getting to Dan."
Dan, with the power of suction, pulled Sandy's calves into him, but was far from full. Slowly pulling her thighs in, he squeezed them, wanting to savor their flavor. Moving onto her ass, neither he nor Kat could resist giving a grope, which Sandy kinda liked. Stretching over it, Kat put Sandy's arms to her sides. Dan quickly sucked up her chest, folding over her shoulders.
Standing up, Kat walked over to the mirror. As Dan's lips began to close around Sandy's nose, Kat stopped him and held them open. "I'm going to give you two choices:" said Kat, "Either I let go and you disappear without a trace, or you become my vagina and I use Dan for something else."
Sandy looked into the mirror.
