Start with just one night

Danny realized that he probably shouldn't commit to anything since it's impossible to undo wishes. Spending a night with her should be enough to know if he wants to keep it going, though. If nothing else, to see if he wants to do this again. Taking the wand in hand, he thought out his wish.

"I wish that Ms. Hopkins would invite me for dinner. Some time during that dinner, Ms. Hopkins and I will randomly become conjoined together until dawn tomorrow morning. At once dawn breaks, we'll be separated into our original bodies. Our conjoined form will be our two heads on a single body that is half hers and half mine, our reproductive organs are arranged so we can have sex with ourselves, and the two of us only have control of our respective sides. Despite the relative seriousness of our situation, she (and no one else that might see us) is no more alarmed about us being stuck together than as if she spilled coffee all over us." With a wave of the wand, there was no way to really tell if anything changed, but then another knock was heard on the door. Without much surprise, it was Ms. Hopkins.

"Hey, Danny. I was just wondering if you wanted to come over for dinner tonight? I don't know if you have anything planned, but I have kind of a boring night ahead of me and was wondering if you could keep me company. I'm just going to be making pasta. Nothing special." The first part of Danny's wish came true, so he can only imagine that the other parts would as well.

"Yeah, I'm free tonight if you don't mind feeding." Danny said.

"Alright. Great!" She said with a smile. Danny never in a million years thought he'd see a smile like that from her, but his wish from before really changed her. A part of him was mentally kicking himself for it, but not enough to stop himself. "I'll see you at 7 then?"

"Sounds good. I'll see you there." Danny replied. With another smile, Ms. Hopkins turned around and started walking away again. Danny couldn't help but watch her behind as she moved until she made the turn to go down the stairs. His cock was already asking for attention. Something that made Danny pause a second.

Right now, the wish will prevent her from calling 911 or otherwise scream at the top of her lungs once they merge together, but if the two of them are stuck and Danny starts sporting a boner because of it, he could be in trouble. Maybe he should make another wish to change her outlook on it...
