One of the coolest things about having a copy of you show up, but with only recent memories, is getting to re-watch your favorite older movies with him because he's never seen them. We had just finished watching Terminator and Terminator 2 (Director's Cut, of course) back-to-back.
"That...was...awesome!" he declared. "Are there any more in the series?"
I screwed up my face. "Um, there are, but I think we should just stop there to avoid disappointment."
"Huh...okay," he replied, and got up to get a soda from the fridge. "You want one?" he asked, holding one aloft.
"Sure."
Then I put on The Matrix.

After a few days of hanging out with Other Tom (I got the idea for that from Coraline), I was getting a bit sick of him. When I went to have some of my leftover pizza, I found that he had already eaten it. He wore my favorite clothes sometimes, and wasn't the least bit sorry.
"They're my clothes too," he said. While the clothes he had arrived in were copies of the ones I was wearing when Oberon had kidnapped me, they weren't my favorites. I was pretty sure that normal siblings didn't have to go through this kind of frustration.
"My brother would dunk me in lava," Demie said when I mentioned it to her, "or rape me up the ass. If all you're complaining about is food and clothing, I think you're doing fine."
I frowned.
Demie gave me a moue of empathy and then grinned. "You sound pretty frustrated. Wanna take it out on me?" She took my hand and pulled me to my bedroom. As I disrobed and she climbed onto the bed, her own clothes disappeared, as they were just part of her shapeshifting body.
She shook her round booty at me. "C'mon, spank me, stud."
I got behind her, gave myself a big wind-up, and then slapped dat ass. SMACK!
"Ooh..." Demie moaned. "Again..."
I smacked her other cheek with my left hand. Not as hard, as I'm right-handed, but my main hand was already smarting from that first one.
"Again!" she demanded.
Instead of going for quality and hurting myself, I decided on quantity. I moved to the side and started giving her whack after whack, paddling with both hands. Soon the red skin of her buttcheeks was even redder.
"Enough. Fuck me."
My cock had flagged a bit through all the exertion - violence wasn't really my thing - but as I got behind her and saw her puffy, glistening pussy lips, it didn't take long for me to get back to full mast. I lined the head of my cock up and pushed inside.
"Hey, Tom, what are you-"
"Fuck!" I yelled, and stopped as Other Tom opened the door.
"Ah, so you are..." Other Tom said as he stopped, watching us. I waited for him to leave but he didn't.
Then he realized: "Oh, shit, you want to be left alone. I'll..." He stopped, considering.
"Or..." both he and Demie said at the same time.
"Um, Demie..." I said, uncertainly.
"Get over here," she said to Other Tom.
Soon I was thrusting into Demie from behind while she sucked on the changeling's cock. We were able to get a good rhythm going, where my thrusting would push Demie forward onto Other Tom's cock, and then as she pulled away from his dick she would push back onto mine. It was actually working out well.
At least until Other Tom grunted and came in Demie's mouth, way sooner than I would have. She licked him clean and then he fell sideways onto the bed as she gulped down his spend.
"Well, you lasted longer this time," she told him as I continued to fuck her.
He looked embarrassed. "Last time was literally my first time, you know. I mean, I remember having sex with you before because he does," he looked at me, "but my body's new and I got overwhelmed."
"Right, virgin changeling," she replied.
I thought back to the night I had lost my virginity, with blonde, bespectacled Tracy on the night of the grad party. I hadn't lasted long either.
"Oh, Tom..."
I looked down. Tracy, with her glasses still on, was before me, looking back with lust as I continued to thrust into the short 18-year-old. I hadn't noticed Demie's pussy had changed shape when she had assumed the form of the girl who had taken my virginity, but it definitely felt tighter, just like Tracy's had. Much better without the condom we had used then, too.
Tracy looked concerned. "You'd better pull out when you're gonna cum, Tom, okay? It's not a safe day."
Oh, Demie, I freaking love you, I thought, and grabbed Tracy's ass so I could thrust harder.
"Ohh, Tom, does that turn you on, knowing that I'm fertile right now? Pleeeease pull out..."
There was no way that I was going to do that. I thrust faster, harder.
"Tommm..." She lowered her head to the bed and I could feel her pussy getting tighter around my cock as her own orgasm approached.
