“Let me know when you’re ready to try a finger,” Ashley said softly.
“I’m ready,” Madison said. “God Ashley, I’m so horny.”
“You and me both,” Ashley grinned. She grabbed the bottle of lube and squirted some more into her hand. She then rubbed it all over her index and middle finger, though she was going to start with just her index finger.
“You ready?” Ashley said, asking for one final confirmation.
“Yes,” Madison said. Her eyes were still closed.
Ashley brought the tip of her index finger against Madison’s asshole. “This should go in pretty easily,” Ashley said. “And it shouldn’t really hurt, either. It’s just a matter of getting used to the feeling of something going in rather than–”
“Yeah, I got it,” Madison said, laughing. “Go ahead.”
“Sorry,” Ashley laughed. She pressed her index finger, which was thoroughly coated in lubricant, into her sister’s ass. There was some resistance, but Ashley was able to get the tip of her finger through Madison’s ass without much difficulty. After all, it was just a finger.
Ashley pushed her index finger roughly half-way into Madison’s ass before stopping. “That’s half my finger. How’s that?”
“Fine,” Madison said. “It’s weird, but not bad. It doesn’t hurt.”
“You want the rest?”
“I do.”
Ashley pushed the read of her finger inside of Madison until her knuckles came to rest against Madison’s asscheeks.
“And that’s all of it.”
“Doesn’t hurt at all, like you said,” Madison said. She was very slowly rubbing her clit now. “I can’t believe you’re fingering my asshole, Ashley.” She chuckled.
“Me too,” Ashley smiled. “Should I just leave it in? Or do you want me to, like, fuck you with it?”
Madison was silent for a second. “Fuck me with it. Be gentle, though”
Ashley nodded. That was a good sign — not that it would’ve necessarily been bad if Madison just wanted Ashley to hold her finger in place.
Ashley began to slowly slide her finger out of Madison’s ass until only her first knuckle was inside Madison. Then, Ashley pushed her way back in no faster than she had come out. Madison picked up the pace on her clit again, getting back into her former rhythm. Ashley gradually increased the speed at which she finger-fucked Madison’s asshole until she was going at a moderate pace. It was not fast at all, not by any means, but it wasn’t slow either. And Madison definitely seemed to be enjoying it. She was moaning an awful lot.
“Does it feel good?” Ashley asked.
“Yes,” Madison groaned. “I think I want to try two fingers.”
“Great,” Ashley grinned. She slid her index finger out and positioned both her index and middle finger together at Madison’s ass. Then, Ashley squirted a bit more lube onto her fingers, though they were both still quite wet.
“You ready?”
“Yes,” Madison said. She opened her eyes for the first time in a while and looked up at Ashley, who held Madison’s eye contact as she slid her fingers into Madison’s ass.
“Oh my God,” Madison said softly.
“You good?”
“Yes,” Madison said. “I like how this feels a lot more.”
Ashley slowly slid her fingers in until her knuckles were against Madison’s asscheeks again.
“What now? Should I leave ‘em for a bit?”
“No,” Madison breathed. Her eyes were closed again. “Keep fucking me with them, please.”
Ashley repeated the same process as before. She slowly inched her fingers back until the first knuckle before sliding them back into her sister’s asshole. Madison rubbed her clit wildly now. As Ashley began to slide her fingers in and out of Madison’s behind, Madison’s moans became more frantic and more urgent.
As Ashley came up to her former max speed, Madison’s fingers were a blur on her clit. Madison’s toes were permanently curled, and her hips bucked and thrusted as Ashley finger-fucked her.
“Oh my God,” Madison groaned. “Holy FUCK!”
Ashley braced herself against Madison’s thigh and continued finger-fucking her little sister’s asshole.
“You like having your sister finger-fuck your ass, huh Madison?” Ashley cooed.
“Yes,” Madison groaned. “Oh my God Ashley, yes!”
“I want you to come nice and hard for me,” Ashley said. She was almost taking on the role I had when Ashley and I had sex, although Ashley was not nearly as dominating as I often am. “Come for me, baby girl. I want to feel your asshole throbbing around my fingers.”
“Uggghhhh,” Madison groaned. “Oh my God, Ashley. Don’t stop, you’re gonna make me come. Oh my God, I’m gonna come!”
“Come for me, Madison,” Ashley cooed. “Come for me, baby girl. Come for your big sister.”
Madison arched her back and cried out. Ashley felt Madison’s asshole begin to throb and pulse around her fingers. She was worried that her parents would hear Madison’s cries of ecstasy.
Madison bucked her hips and massaged her clit wildly. Her pussy was absolutely soaked. Her orgasm hit her like a truck, intensified by Ashley’s fingers sliding in and out of Madison’s ass. Her body bucked and spasmed as she rode out wave after wave of pleasure. The feeling of Ashley’s fingers sliding in and out of her asshole was like nothing Madison had ever experienced before. As she finally stopped coming, Madison sighed deeply. Ashley quickly slid out of her ass and washed her hands. Madison was breathing hard.
“So?” Ashley asked, smiling. “How was that?”
“Amazing,” Madison said as she tried to catch her breath. “I loved how it felt when you had two fingers inside me. One was alright, but two felt incredible.”
“I could tell,” Ashley grinned. “I’m surprised you enjoyed it so readily. It actually took me a while to get used to the feeling.”
Madison sat up and leaned against the tub. “Yeah, I don’t know,” she shrugged. “I definitely liked it, though.”
“I’m glad,” Ashley said. She leaned forward with her arms spread. Madison leaned forward and accepted Ashley’s hug.
“Thank you for helping me,” Madison said as they held each other.
“Of course,” Ashley said. She kissed Madison on the cheek before breaking their embrace. “Normally I would stay and make myself come, but I’m actually starving for some reason.” Ashley picked up her shirt and her panties and slid them on. “I’m gonna go eat breakfast.”
“Okay,” Madison said, yawning. “I guess I’m still gonna shower. Where’s Brian?”
“He’s in my room still, probably,” Ashley said. She had put on her panties and was now pulling her shirt over her head. “I imagine he’s urgently waiting for me so I can tell him what happened, although I’d honestly be surprised if he didn’t hear you coming.”
“Was I that loud?” Madison turned bright red. “Do you think anyone else heard?”
“Uh, yeah, you were loud,” Ashley laughed. “But I don’t think anyone else heard. Plus, mom and dad are probably not even awake yet.” That last part was a bit of a lie. There was a chance somebody heard, at least if they were by the stairs, but it’s true that their parents were likely still sleeping. It was only about 8:30am, and they usually didn’t get up until at least 9am.
“That’s good,” Madison said. “I guess I’ll see you after breakfast. I’ll have to get you back for making me come this morning.”
“Well, I only really helped you come,” Ashley grinned. “But yeah, for sure. Maybe you can finger my ass next time.” She gave Madison a wink and quickly crept out of the bathroom. She darted across the hall back to her room, where I was waiting. I had definitely heard Madison’s orgasm, and I was still pretty hard. (Hearing it made me hard. What do you expect?)
