My parents were watching TV when we got home. I was worried about them being in the house while we were having sex upstairs but Lily set me straight and told me there was no chance I was going to make her scream so they would never know. It was a hell of a confidence boost. I feigned a sulk while she laughed, before she promised she would make it up to me. The raspy way she whispered it into my ear brought me back to life.

Dad was asleep anyway, passed out on the sofa while his wife seemed more focused on her phone than whatever was happening on the tele.

Back in my room, we were alone, and faced with a destiny that I had set in motion a little over 24 hours prior. It had taken a few journeys from the car and up the stairs to get all of her bags onto my bed, and they were her immediate priority upon our arrival. I sat on the edge of the bed and watched her start to unpack. “Where can I put all of this stuff?” Lily asked.

“Uh, not sure,” I said, climbing to my feet. “I don’t have much room, but there’s an empty wardrobe and a chest of drawers in my sister’s old room. I suppose that can be yours for now.”

“I want to sleep here,” she said, which made me smile. I enjoyed cuddling her last night. I would be happy to do it again, as long as her tail was warned about its behaviour.

“You can, but you can still keep your stuff in there.”

“Okay,” she said. I led her to my sister’s room, with the first set of neatly folded clothes. “This is nice. She won’t mind?”

“Not at all, she lives abroad so she won’t be back anytime soon,” I answered. My older sister’s room was still partially decorated from her fandom days. One Direction and K-pop were her favourites, and she had ticket stubs and lightsticks displayed proudly across one wall. The bed wasn’t made, and the curtains had been taken down, so it wasn’t looking too homely, but it would be a nice place for her to relax if she ever wanted privacy.

“She can keep the clothes once I’m gone to make it a fair deal.”

“Fair enough,” I said. I didn’t know if I wanted to see my sister in some of that stuff, but she’s an adult and she can take it if she wants. Besides, Lily was inside the ghostly essence of another sister anyway, so I suppose it wouldn’t be all that different if my real sister got herself some nice, new clothes.

Lily made the journey a couple more times, but partway through folding and packing away she got bored, turned to me and stared at me with hungry eyes. “Sex?” she asked, and my own eyes bulged.

“Now?” I asked blankly, and she took my hand and guided me back to my room.

Lily closed the door behind us and then stopped just short of me. “Yes, now,” she said, before taking off her sports bra. Her tits bounced as they set into their natural position. I drank them in, perhaps more than ever. I had my hands on them earlier, but she was pressed closer to me then and now she was at a distance. The view was spectacular. Her tits were big, a little more than a handful for me, with a teardrop shape and pink areola. Her nipples seemed to rest in a naturally stiffened state.

I took off my shirt, and she reached out to graze a sharp fingernail across my abs. My dick was already pulsing. “What do you want to do?” I asked, nervous and mumbling. “You’re in charge.”

“Sex education starts tomorrow. Your first experience shouldn’t be a lesson,” Lily said, stepping closer and letting that nail move up to my chest, teasing one of my nipples. “Your first time is about you, not me, so relax and have fun because sex with me is the easiest you will ever have.”

“Why is that?”

“All I need is your sexual energy, and your passion, and your hunger for me. That will feed me, and the cum you give me is the cherry on top. You don’t need to be nervous or embarrassed because that sense of shame doesn’t exist for my kind. Sex is supposed to be shameless, and if you don’t cringe at the things you said or the way you acted when you were doing it, then you were never truly letting go.”

I never expected such an inspiring speech. I didn’t just want to fuck her. I wanted to go to war for her, and so did my dick. I started to take off my jeans as she spoke, and they were being kicked off my ankles by the time she finished. “That’s me told,” I said, and she giggled.

“Don’t get too cocky when I orgasm. I am going to cum more times than you can possibly imagine, but it’s going to be a lot harder when it’s a real girl.”

“I thought you were a real girl,” I said, and her eyes glowered red.

“I will be,” Lily hissed, before pushing me back onto the bed. It wasn’t as hard as when she kicked me, but there was a little bit of time spent in the air before I hit the mattress. I pushed my boxers down my legs as she stepped out of her shorts. She fell to her knees in front of me, shuffling between my legs. “I’m going to show you another magic trick.”

My dick was half hard as her finger pressed into the underside of the head, and rock solid a moment later. I went light headed as she repeated the trick she pulled the night before, leaning back onto the mattress with my elbows. She really had instant hard-on powers, but this time the surge of power was overwhelming. This didn’t even feel like a tease because she was so focused, her eyes missile locked onto my cock as pulse after pulse of energy flowed through my body, until my balls tensed and my cock exploded. I came hard, shooting a couple of ropes up into the air, before they fell to land back on my skin. The rest of my load spilled out of the head and trickled down my shaft like a water feature.

I was twitching in pleasure as my dick quickly softened. “What the fuck,” I said, feeling the dream of sex dissipating.

“Patience,” Lily whispered. She leaned in and started to lick around my throbbing cock, cleaning up the cum around my balls and thighs. After she had mopped up everything she could find, she took a deep breath and placed her finger back on my cock. She stroked along the frenulum and closed her eyes, and her power flowed through me one more time. It wasn’t instantaneous on this occasion, but my cock hardened for a second time.

I fell back into the mattress, panting. I had barely moved an inch and she had already exhausted me, stealing something within me and using it to power my cock up twice in quick succession. “What the fuck,” I repeated, this time to the ceiling.

“Now you’ll last longer,” Lily said, sounding very proud of herself.

“You can do that?” I wailed.

“Kinda,” she said. She was back on her feet now. “It’s not infinite but it’s good for longer sessions, or newcomers.”

“My brain hurts,” I moaned, and she fell on top of me, giggling.

“You’ll be fine in a minute,” she informed me. Her hand went to my hard dick and started to slowly wank me off. She straddled me and soon had two hands on my dick, just like she had in the changing room. I watched her boobs jiggle as she played with me, so delirious from the energy sapping that my head started bobbing with them, until she noticed and started giggling. “Want me to ride it?”

“Yes, please.” My answer was immediate, and probably desperate, but she loved that energy.

Lily moved forward, guiding my cock to her opening and hovering over me for a moment. She hesitated just enough that I had to take a second breath to compose myself, before she started to lower herself onto my cockhead. She was soaking wet, so slipping inside her was easy enough. She slowly took me in, inch by inch, until she was at the base, and she sat still on my waist.

Her skin was warm, and her mouth and breath molten, but her pussy was another level on top of that. I moved my hands to her hips, holding on for dear life, and she wasn’t even moving yet. Her pussy was like a vibrator, massaging my cock even as she remained still. “So good,” she said, running her hands up her body and then to her head. She ran her fingers through her hair, stretching to the ceiling as the energy pulsed through her. “It feels better every time.”

She leaned forward, putting her hands on my chest, before starting to rock her hips back and forth. Her eyes were less focused than any other time I had looked into them. The tease was gone, and she was just enjoying herself. She rode me effortlessly, sliding up a few inches of my cock with each rock forward and taking me back to the hilt with each journey back. I held her hips, and then waist, before reaching for her breasts. I gave them another squeeze, before pinching her nipples the same way I did earlier. I was a little rougher this time around, bringing her back to attention. “You’re so good,” I said, and she smiled.
