*****
When I woke up, I was already hard. I put my hand on the sheet where she’d come on the panties. It was dry now. It didn’t matter. I thought about her pussy stretching around me, then my brain skipped the polite part and went straight to her ass. I’d paid for the plug. I’d paid for the beads. But all night they’d sat in the box like a dare I was too chicken to cash.
Mom was at work. The house had that empty weekday sound. I shoved the covers down and let my cock rest on my thigh. I was about to wrap a hand around it and finish to the idea of pushing into my sister’s ass when my door slammed open.
Lila, naked again, blonde hair a mess and tits out. In one hand she had the butt plug from the order, still with the little tag plastic stuck to the base like she hadn’t bothered to pick it off. In the other, the beads, black knots on a string.
“I need help,” she said.
I sat up so fast the bed complained. “Jesus, Lila—”
“Don’t Jesus me. I tried. It doesn’t go.” She tossed the beads on my comforter and held the plug up. “You’re going to put this in.”
“Do you even have lube?”
“Of course I have lube.” She grabbed one of my pillows and threw it at my head. I caught it. She looked down to the giant tent. I’d stood up without thinking. Her eyes flicked to my morning wood and stayed there a second too long.
“Your room,” I said. “I’m not doing this on my sheets after last night.”
She rolled her eyes and walked. I followed her across the hall with the plug and the beads and a hard-on I couldn’t negotiate with. Her ass was right there in front of me, heart-shaped, pale, the faint bikini line, the tight little hole I was about to put silicone in. I wanted to grab her. I wanted to go back to bed and pretend I was a person.
In her room, she kicked clothes off the bed and got on all fours like she’d watched a thumbnail. Then she looked back over her shoulder.
I stood there with the toys. “I want something. If I’m doing this.”
“You already fucked me.”
“This is different.”
She stared at me. Then she said it like she was bored, which was how she said the dangerous things. “You can fuck my ass. After. If you don’t make it weird.”
I smiled internally. “Okay.”
“Lube’s in the drawer. Don’t use the whole bottle, I’m borrowing it from a friend.”
“What kinda freaky friends do you have?”
“Shut up.”
I found it. Cheap pump bottle, still sealed. I clicked it open and warmed some on my fingers because I had watched enough of the wrong internet to know cold lube makes people flinch. I put a hand on her cheek and spread her. Her hole was small, pink, and it winked when I rubbed lube over it. I pressed a finger. She was tight enough that the first knuckle felt like a bad idea. I worked it until she pushed back.
“Plug,” she said. “I’m not doing finger school.”
I coated the plug. It looked bigger in my hand than it had on the site. I set the tip against her and pressed but nothing. I pressed again. Her rim opened a fraction, a wet little O, shiny with lube, and then the widest part of the head popped through. She gasped. I watched it happen: the stretch, the way the pink went pale around the silicone and the way her ass took it whether she liked the burn or not.
“Fuck. Slow.”
I was slow. I fed it in until the neck settled and only the flared base sat outside her, a dark circle against her skin. Her hole clenched around it and stayed stretched. I had to look away before I came in my shorts.
“An hour,” she said, voice wrecked. “It stays in an hour. That’s how you do it.”
“An hour.” I was disappointed. I badly wanted to fuck her ass.
“Breakfast. I’m starving.”
We went downstairs like that. She pulled on one of my shirts and nothing else. The plug made her walk like she was thinking about every step. I made sandwiches because if I sat still I was going to lose my mind. She ate hers standing at the counter, shirt riding up, the base of the plug visible when she reached for a glass.
After we’d eaten, on the couch she didn’t sit next to me. She sat on me. Ass in my lap, plug and all, grinding back against the erection I hadn’t lost since the door opened. The shirt was the only thing between us. I could feel the hard flare of the base roll over my cock.
“Lila … Can we do it now?”
“What. It’s been forty minutes.” She rocked again, mean and slow.
I put my hands on her hips and didn’t pull her down. I also didn’t stop her. Blue balls wasn’t a phrase until she made it a physical condition. She sat like that, her weight on the plug, my cock trapped and leaking. “It’s getting painful.”
“Alright, you can take it out,” she said.
Finally. I followed her up the stairs already pulling at my waistband. She went to her room and got on the bed on her side, not her knees. Then she took off my shirt. “Beads first. I didn’t come downstairs for you to skip the other thing you bought.”
“You really know how to get on my nerves.”
She grinned and rubbed her foot on my bulge. “I’m waiting.” She turned around and flashed her beautiful ass.
I could have argued, but I pulled the plug instead. It came out with a wet sound and her hole stayed open a second, shiny, used, before it tried to close. She hissed.
The beads were worse because they were honest. One knot, then a bigger one. I lubed them while she went on all fours on top of her bed. I pressed the first bead to her and it went. She made a little sound. The second took more. I watched her ass swallow each one, the string disappearing, her rim stretching and shutting around the silicone.
“That’s good,” she whispered. “That’s … keep going.”
I kept going until only the retrieval ring sat outside her. She was breathing through her mouth. I was so hard it hurt, a dull sick ache. I sat on the edge of her bed and didn’t touch myself because if I did it would be over.
She reached back, found the ring, and looked at me.
“Okay,” she said. “You can fuck me anally. Now hurry up before I change my mind.”
I pulled the beads out one at a time. She whimpered on the last one. Her hole was slick and open and I almost forgot the rest of the steps.
She didn’t. She rolled over, sat up, and took my cock out of my shorts. She spat on it, then put me in her mouth, wet and sloppy, not trying to get me off, just getting me shiny. The heat of her tongue after an hour of the plug almost finished me. I grabbed the headboard.
“Lube,” I said. “I’m not going in on spit.”
She pulled off and pumped more into my hand. I spread it on her ass, two fingers, then three because she was already open. I coated myself until I was dripping.
She got on her elbows and knees again. “Slow. I mean it.”
I lined up. The head of my cock looked obscene against her. I pushed. Her rim opened around me the way it had around the plug, except I could feel it, hot, tighter than her pussy had been last night, a ring that didn’t want to give and then suddenly did. The head popped in. She moaned out into her arm.
I stopped, buried an inch. My sister’s ass clenched on me like it was trying to push me out and pull me in at the same time.
“Jack—”
“I know. I’ve got you.”
I gave her another inch. The stretch showed: pale skin taut around my shaft, lube squeezed out in a shiny ring. I was fucking my little sister in the ass. I thought about Mom at work. I thought about the wall and the pink vibrator and the panties. I thought: this is the part you don’t come back from.
She pushed back. I slid deeper, about halfway, then three-quarters. Then I was in her to the base, my hips flush to her ass, her hole stretched wide around me, fluttering.
“Full,” she said. “Don’t move. Just, don’t.”
When she started rocking I took that as permission. I fucked her ass slowly at first, short strokes, watching myself disappear into her gorgeous ass. The drag was filthy. Every pull her rim clung to me. Every push she made that punched-out sound I used to hear through the wall. I went deeper and harder. The bed hit the wall in a rhythm I hoped the neighbors didn’t know.
“You’re in my ass,” she said. “You’re really in my ass.”
“You’re my sister.”
“I know. Fuck me anyway.”
I did, hands on her waist. Her tits swung. Blonde hair stuck to her back. I could see everything: the stretch, the lube, the way her hole stayed open when I pulled back and then swallowed me again. Taboo wasn’t a concept. It was the heat around my cock and the fact that I never wanted to pull out.
She came first, sudden, her ass locking down so tight I thought I was in heaven. She shoved her face into the pillow and I felt her pulse around me. That finished the last of my control. I slammed in to the hilt and came in my sister’s ass, raw, pulse after pulse, grinding through it while she held me there with her hips. I emptied into her until there was nothing left, until I was twitching and oversensitive and still stuck in that tight ring because pulling out felt like admitting it.
When I did pull out, I did it slowly. Her hole stayed open, pink, shiny, and I watched my cum leak out of my sister’s ass onto her sheets.
She dropped onto her side, breathing hard, and reached back like she wanted to feel it. Then she looked at me, mean and satisfied and a little wrecked.
“Hour was worth it,” she said.
I lay down behind her and put a hand on her hip, thumb near the mess I’d left. “Totally.”
