Now properly lubed up, Erika approaches the presenting Tina and places her hands on her butt cheeks. Spreading them wide, she teases the hole with the head of the dildo, letting her know what is coming before she slowly, but firmly, begins to press the rod inside. She gives Tina's body a chance to adjust to each inch, enjoying the feel of the motions of the smaller, inward facing dildo stimulating her slit.
It feels quite nice but she suddenly finds herself momentarily wondering how this feels compared to a real dick... and if she should maybe ask around if anyone knew a spell for that. It would not be anymore strange than some of the other magic she had already seen... but that was for later. For now, as she continued her almost maddeningly slow insertion, she had an asshole to claim.
