As you opened the door, your eyes widened in surprise as you saw your sister Melissa standing there. She was wearing her work attire, a black suit with a crisp white shirt and a red tie. Her shoulder-length hair was neatly combed to the side, and she had a tired yet professional look on her face. You noticed Riley, the Mutt, standing behind you with Sarah, and your heart skipped a beat. You hadn't told Melissa about this whole situation yet.
"Hey, Mark," Melissa said, walking into the house. "What's going on?" She glanced at Riley and then back at you, seemingly confused.
"I've found out that I have the ability to swap heads.", You said as you explained to your sister about Riley and the woman you encountered.
Melissa raised an eyebrow, looking at you as if you had just told her you could fly. "I see...," she said slowly, not quite sure what to make of your story. "And you brought him home?"
"Yes, I thought you might want to keep him. He seems to be adjusting well to his new body." You shrugged, trying to act casual. As you turned you see Riley humping a large pillow despite having a woman's body underneath his canine head.
Melissa's eyes widened in surprise and then she burst into laughter. "Oh my god, that's hilarious!" she exclaimed, wiping a tear from her eye. "I really never know what to expect with you, Mark." She walked over to Riley and patted him on the back. "I guess I'll keep him for now, but you have to promise me that you won't tell anyone about this, okay?"
You nodded, relieved that Melissa seemed to find the situation amusing rather than alarming. "Deal," you said with a smile. "And hey, maybe he could be good company for you since you live alone. You know, keep you company while you're here."
Melissa smiled back at you. "Well, I suppose he could do that. I mean, it's not like I have much of a social life anyway." She scratched Riley behind the ears, and the Mutt, still having a woman's body from the neck down, seemed to enjoy the attention. "So, what do you want to do with the rest of the day? Want to order some pizza or something?"
"Sounds good to me. Let me just grab my wallet and I'll order." You said as you headed over to the couch and retrieved your wallet from the coffee table. "Do you want anything specific, Melissa?"
