Exhibitionist Sister – Chapter 9 by superwriter1337

“Sounds like you guys had fun,” I said as Ashley came blasting through the door. “Why are you in such a hurry?”

“I’m hungry,” Ashley said. “And I’m pretty sure Madison would be happy if you went to the bathroom right now. She asked where you were as soon as we finished.”

“Really?”

“Mhm,” Ashley smirked. “Go on. She can fill you in on the details.” Ashley grabbed a pair of shorts from her dresser and slipped them out. We walked out of her room together. She continued down the hall while I stopped at the bathroom door. She blew me a kiss as she turned the corner to head towards the steps.

I knocked twice on the bathroom door.

“Uh,” I heard Madison’s voice. “I’m in here!” I guess she wasn’t sure if it was me so she was warning whoever may have been knocking that the bathroom was occupied.

“It’s Brian,” I said.

“Oh, okay,” she called. “You can come in!”

I quickly opened the door and closed it behind me, locking it. My heart skipped a beat when I saw Madison sitting naked on the ground in front of the bathtub. She was sitting with her legs crossed so I couldn’t really see between her legs too well, but I could see a strip of public hair peeking out above her calves. What I could see were her naked tits, and even though this wasn’t my first time seeing her them, you best believe I became rock-hard instantly. There was something so dirty about getting to see the naked tits of my girlfriend’s sister. Knowing my girlfriend had sucked on those nipples — her sister’s nipples — made it even better.

I was only wearing a pair of boxers (and nothing else) so it was immediately obvious that I got a boner. Madison blushed and smiled when she saw how hard I got (and how quickly I got hard for that matter).

“You’re already hard?” she said. It wasn’t so much a question as an observation.

“Oh yeah,” I grinned. “You’re naked. How could I not be hard?”

“Well, it’s very flattering,” she said, still smiling.

I went and sat down across from her, much like Ashley had done when she first walked in.

“Did Ashley tell you anything?” Madison asked.

“No,” I said. “But based on the fact that you’re naked and your nipples are still hard, I have a feeling you and Ashley had a little fun together.”

Madison blushed again and looked down at her chest, noticing that indeed her nipples were quite hard.

“I could just be cold, y’know,” she smirked.

“Well, are you cold?” I teased.

“No,” she laughed. Then she grinned at me. “I kept my promise from last night.”

“Did you now?” I returned her excited grin.

“Mhmmm. And obviously I recruited Ashley for help. She came in here and at first, we just masturbated together.”

“Right.” My dick was already leaking precum in my boxers. I don’t think I’ll ever stop getting ridiculously turned on by my girlfriend and her sister masturbating together.

“And then when I decided I was ready, we discovered that the positioning was a little awkward. Like I couldn’t easily prop myself up to comfortably rub my clit and touch my butt at the same time, which is what Ashley suggested I should do. It just wasn’t particularly comfortable.”

“Sure,” I said. I guess I understood what she was saying. I mean, I don’t think it would’ve been particularly difficult to get a finger in her ass while she masturbated, but I imagine she was nervous and whatnot.

“So Ashley offered to play with my butt herself so I could focus on rubbing my clit and being comfy.”

My jaw dropped. “And did she?”

Madison just smiled and nodded.

“Ho-ly shit,” I said. My girlfriend actually fingered her sister’s asshole! Or at least, I assumed she did. Madison hadn’t explicitly said that yet.

“Yeah, it was admittedly pretty awesome,” Madison said. She was all smiles right now. “At first, she just rubbed the outside of my butthole. Once I was ready though, she stuck her finger inside me.”

“Did you like how it felt?” I asked. My cock was throbbing at this point. I wish I had been there to see this. Ashley fingering Madison’s asshole? Holy fuck.

Madison nodded. “Yeah. It was a little weird at first for sure, but I got used to it pretty quickly. I actually had Ashley put a second finger inside me. Now that really felt good.”

“Two felt better than one, eh?” I asked, amused. “Seems like your ‘poor little butthole’ can handle more than you thought.”

Madison laughed. “I guess so. Ashley said it took her way longer to start enjoying the feeling than it took me.” She shrugged. “I thought it was great.”

“I have to ask, did the fact that your own sister was the one, you know, fingering your ass make it better or hotter or whatever?”

“Yes,” Madison said, blushing. “Fooling around with Ashley feels so dirty and so wrong. That makes it a lot hotter.”

“I mean, I agree,” I said, shrugging. “So is that all the details you have for me then?”

“Basically,” Madison said. “She did, like, actually finger-fuck me. She didn’t just leave her fingers inside me without moving them or anything.”

“Jesus,” I said. “I really wish I was there to see that.”

“Yeah, it must’ve been quite a sight to behold,” she giggled.

“Did you come?” I asked with a slight grin.

“Yeah, it felt great,” she said with a smile. “Aren’t you proud of me? I managed to have two fingers in my butt!”

I laughed. “Yes Madison, I’m proud of you.” She laughed with me.

She let out a sigh and then was silent.

“I guess I’ve gotten you pretty worked up, huh?” she asked after a moment. She was looking at the large bulge in my boxers.

“I’d say so, yeah,” I chuckled.

She blushed and then looked back down at my bulge. “Isn’t it a little unfair that I’m sittin’ here naked and you’ve still got underwear on?”

“Y’know, I do see your point,” I said, playing along. “You reckon I should take these off?”

“Well, it would only be fair,” she said.

I smirked. “I suppose you’re right.” I stood up and hooked my thumbs into my boxers, sliding them down off my legs, allowing my cock to spring free. I kicked them off my feet, and they settled in a clump behind where I was sitting. I stayed standing for a moment, letting Madison get a good look at my cock. She looked at it hungrily.

“Better?” I asked after a moment. I sat back down but didn’t cross my legs.

“Much better,” Madison nodded. “Although…”

“What is it?”

“It’s just that your, erm, ‘thing’ just looks so swollen and hard,” she said, biting her lip softly. “It really looks like it needs some attention.”

I looked down at my dick. “I think you’re right,” I said. “What do you think I should do?”

“Hmm,” she said, pretending to consider various options. “Honestly…” she paused for another moment. “I think you need to have an orgasm. What do you think?”

“That’s a good idea,” I nodded. “It’s just… I don’t know, I’m kind of groggy after just waking up, you know?”

Madison laughed. “Would you like some help, Brian?”

“Yes, please,” I nodded eagerly.

“You should come here,” she said, reaching behind her and patting the side of the bathtub. I nodded and stood up. I walked over — my cock bouncing up and down with each step — and sat on the edge of the bathtub with my feet outside the tub. Madison swiveled around on the ground to face me, sitting on her knees now. Madison grinned. I spread my legs a bit and braced my hands on either side of me against the edge of the bathtub. My cock was sticking out into the air with my balls hanging down beneath it.
