After-Hours Window

My body convulsed. I raised onto the balls of my feet; my stomach tightened and bent me forward pulling my pelvis away from my sister's head; my mouth opened wide involuntarily as my body tried to force out a noise. I peaked. My body snapped upright and my hips moved back to Jenny's mouth just as I showered her in my deliciously sweet cum. I wish I'd have seen my pussy soaking her face but the intensity of the orgasm took away any control I had over myself. Having her fingers still sliding in and out of my ass prolonged the euphoria and I felt another deluge of my liquids squirt out. I could only hope and assume that she was tasting as much of me as possible. I somehow managed to make a mental note to try to not waste the precious nectar that far too often collected into a puddle on the floor.

I took a deep breath and managed to gain enough control to look between my legs and force out another cum drenching squirt. Thankfully she was underneath me downing everything she could. What a fucking woman she was. My cunt relaxed and opened as the last trickle spilled into my sister's mouth. My legs were weak so I lowered myself to the floor opposite Jenny and looked at her in all her naked beauty. I could see drops of my pussy's secretions covering her face and tits. If I hadn't been coming down from a massive orgasm, I would have used that image to get myself off instantly.

"It's like a drug, Ash. Your cum. Is it sweeter because my mind knows you're my sister or are your insides coated with sugar?" she asked playfully.

"Who cares. Just enjoy it." I responded.

We sat there for 30 seconds catching our breaths. Jenny decided to suck her fingers clean that had just come out of my ass. So many things she did were just so fucking hot to me that I could barely stand it. Then she got on her hands and knees and moved the short distance towards me. I watched her hanging tits sway as she approached. She pushed me to the floor and lay on top of me; our cum and piss-soaked tits pressed together. She kissed me and I could taste my juices on her tongue. It was a passionate moment that had an unusual element of romance flowing through. I grabbed her ass with both hands and squeezed its firmness with delight. She slid up me a little because of the liquid lubrication between our bodies. We both laughed as she nearly fell off me.

She rolled off and lay on her side next to me, propping her head up with one hand. I noticed one of her juicy tits lying on top of the other thanks to gravity.

"What now?" Jenny queried.

"Well, my lovely sister, what would you like to do now?" I posed back, unusually ceding some control to her.

"Ahh..." she hesitated, "I quite enjoyed tasting your ass. Maybe we could taste mine now?" she asked with a sense of shyness.

I nearly jumped out of my skin in excitement but managed to cooly say, "Sounds pretty fucking good to me."
"How do we do it? I've never had anything go up there before." she admitted nervously.

"Aww, bless. You're too cute. Don't stress, I'll work you up to it." I was going to have to take it easy to begin with... but that didn't mean I had to finish it the same way. "Get on your knees and lean over the bed." I said softly. She sat up but before she could move away, I stuck a finger in her mouth to open it and spat in there. "Remember, I love you. I'll make sure this is good for you." I said as she swallowed my saliva.

Jenny crawled over to the bed and got into position. I pushed her knees together on the ground, exposing her asshole. The urge to stick a finger straight in and go to town on her was there but I wanted her to feel safe and enjoy it. So I would have to "settle" for rimming her first.

I stuck a finger in my pussy before rubbing it on her rim. I figured I may as well enjoy the taste of myself a little bit too. Then I spread her cheeks wider with my hands and leant into her crack with my face. I licked her anus in a circular motion and she pushed her hips back into my face in approval. I wasn't able to taste her ass yet because it was still closed tight. I'd have to keep working it with my tongue and gradually introduce some pressure with my fingertip before eventually slipping it in.

I continued eating my sister's asshole for a minute or two and then rubbed her clit with one hand. I felt her anus slightly relax with my tongue as she focused on what I was doing to her pussy. So I put a fingertip from my other hand in the middle of her asshole while I kept licking. The stimulation felt good as she kept moaning softly. I began placing more pressure with my finger and it compressed her rim down. I was close to getting through but she was putting up a lot of resistance. Finally, I popped my head up and spat a load of saliva right on her hole. I got my finger back on it and rubbed her rim with enough pressure for it to squeeze through and down to my first knuckle. She grimaced in pain and clenched my finger. "Just hold it there, Jen. Try to relax your ass and focus on me touching your pussy." I urged.

I kept my finger in her ass very still as massaged her clit and listened to her breathing. It took a moment but she relaxed and the pressure eased off enough for me to push my finger in up to my second knuckle. Again she clenched but this time I wriggled it around gently, tickling her insides. She breathed out deeply. "Are you ok?" I asked concerned.

"Mhmm. Keep going. I'll get there." she told more, probably trying to convince herself more than anything. A lot of enjoying anal sex is getting your mind passed the notion that something is fucking your ass. If you can relax enough, it inevitably feels great. It's not easy and it takes a strong person and patience but if you can get there, it's worth it. Plus having your sister ease you into would also be a plus in my column.

I pulled my finger out to the first knuckle and watched her asshole release it easily enough which was a good sign. Back up to the second knuckle and this time with much less resistance. We were nearly there. I slowly pulled my finger out all the way and her rim was open enough to slide my tongue in. I reached my hand up to her face and my tongue to her ass. I jammed my tongue in as deep as I could while simultaneously sticking my finger, that had just been in her rectum, into my sister's mouth. My pussy got excited again at the fact my sister and I had managed to taste her ass for the first time in synchronicity.

My tongue dove back into her slightly agape hole, feeling the tensity of her anus all around it. I licked inside her magnificent ass to coat my tastebuds with her flavor. Everything that I'd tasted from my sister had been exquisite and this was no exception. She moaned more as I licked her inner walls like the perverse being I was. I pulled my finger out of her mouth and easily slid it back into her ass. There was no pain this time as I got the full length of my finger in. Then I really started finger-fucking her with little concern for any pain. She started moaning loudly as I began pounding my hand down, slapping her cheeks as my finger disappeared fully into her rectum.

"Fuck my ass hard, Ash." she commanded. "Stick another finger in me, you cunt."

"What a dirty bitch. And she's making my nipples hard." I thought. Obviously, I did exactly as she told me. I stuck a second finger in and she took it like she'd been getting ass fucked for years. I couldn't waste the arousal this was giving me. "Jen, I'm going to stop for a second and you're going to put your pussy in my mouth while I keep fucking your ass."

"Seriously?" she said annoyed at the prospect of losing the momentum she'd built up.

"Trust me." I said and pulled my finger out before laying on the ground. Jenny spun around and mounted my face. I pulled her body onto mine so we found ourselves in the 69-position. "Don't worry about my pussy, just enjoy getting off first." I said to her generously as I licked her clit and shoved two fingers back into her slippery asshole. From this position I could see her rim swallowing my digits as I pushed them as deep as I could. I knew she had to be getting close to cumming by the tightening of her muscles.

I reached my free hand down and managed to get it to my own clit and masturbated myself. The dual sensations of sucking my sister's cunt and feeling the inside of her ass had started to push me to the edge too. I moaned with her pussy dripping into my mouth. Then she moaned, held her breath and let the climax surge through her. I opened my mouth ready for her to ejaculate. Her body convulsed. Then the torrent of her cum filled my mouth and soaked my face.

I was swallowing her sweet juices when I suddenly felt Jenny move my hand off my pussy before eating me out. She was moaning into my cunt and riding her orgasm but still managed to help get me off too. What else could a woman ask from her sister? I kept smashing her asshole to extend her pleasure and excite myself more in the process. She squirted my face again with so much cum that it filled my eyes and left everything blurry. I screamed in ecstasy as my own orgasm started to take over. My body quivered in elation and then I sprayed my pussy juices all over Jenny's face again just as she was doing to me. I wished this moment would never end.

I wished I had recorded my sister and me; faces buried deep in each other's legs, screaming wildly in pleasure while saturating each other in cum and drinking it out of our ejaculating pussies all at the same time. That was perfection in my book.

I lost the notion of time in my out-of-body experience. I'm not sure how many times I came in her mouth or how much of her squirt I drank. It must have been a solid minute before my dopamine levels dropped enough for me to come back down and take stock of my surroundings. I hadn't noticed Jenny roll off me but as I looked to the side to see her again in the fetal position, her quivering ass was sending ripples through the puddle of cum between me and her. We lay there for a couple minutes, breathing heavily, before I asked, "Are you ok?"

"That was the most amazing thing I've ever felt." she replied. I smiled from ear to ear, happy that my sister had enjoyed it and proud that I was able to bring so much physical pleasure to someone.

"Ready to finish off?" I probed.

"You want more?" she said with surprise. "I don't think I can cum again."

"That's fine. We're going to piss on each other. I love finishing off that way." I replied.

"Why?" she queried.

"I guess it's just my kink. The thought of it just makes me tingle for a long time after I've finished fucking." I told her honestly. I'm not even sure I knew myself up until that point.

"Ok." she said supportively. "Let's go piss on each other. But I need to go first. After all your tasty cum that I've drunk, I really need to go." That just further cemented in my mind that she was the best sister ever.

We pulled ourselves up and walked to the bathroom. I sat down against the bath and looked up at her. "Shower me. Piss on my face and let it run all over my tits." I instructed. She put her legs either side of me and pushed her pelvis forward. I watched as her pussy relaxed and then released her golden piss all over me. I opened my mouth and let it fill with her warm liquid. I drank it down, enjoying the flavor as it ran over my tastebuds and down my throat. I felt the warmth of her body in her urine as it covered my face and ran down to my tits. I washed my body in it making sure my skin was covered. I drank more as her powerful stream kept coming. I know the contradiction but I felt cleansed by her piss, both inside and out.

Her flow began to slow so I opened my mouth again and let it fill up. Once she was done, I stood and opened her mouth. I grabbed her head and spat her piss into her mouth. She let it coat her mouth to get a proper taste. Then she swallowed it. I opened her mouth again and spat in it before kissing her passionately. I loved being nasty with her.

Then it was my turn. I sat her on the floor and put my pussy onto her open mouth. We'd formed a seal as I held her head against my groin. "Look me in the eyes and keep drinking as much as you can." I urged. I released my bladder directly into her. I could see her throat moving as she gulped down my piss as quickly as she could. After three mouthfuls she began to struggle so I pulled away allowing my liquids to cascade down from her mouth and onto her tits. We stared into each other's eyes intently as she kept drinking me. Then I pulled tilted my pelvis up to piss on her forehead and watched it envelope her face. I emptied the last of it and quickly got on my knees and began licking her face. Once that was clean, I licked her tits and finally I shoved my head between her legs and savored the taste of her piss-soaked pussy.

I lifted my head to be face to face with my sister. "I can see why you like that." she confessed.

"It's something, isn't it? People will never know what they're missing out on." I felt disappointed for them as I said it.

"Yes, but most people won't be drinking piss right out of their sister's beautiful pussy." she said matter-of-factly. "Should we have a shower? An actual shower..."

"Absolutely not! I'm exhausted and we're going to bed like this. I want to wake up in the morning and smell our bodies covered in it." I said to her, disappointed that she wanted to wash it off.

"Seriously? Fuck. Ok. Let's go to sleep covered in each other's cum and pee." she replied with some apprehension still in her voice.

I slept like a baby that night. I woke up a few times and pressed my big tits into her back as I smelled the scent of our juices emanating from our skin. I felt Jenny's own tits on my back a number of times and smiled in contentment.

I woke up first in the morning and saw the light bouncing off her naked body. I thought I may as well end our hotel stay in style so I spooned her and held her cleavage. Then I reached my hand down between her legs and started masturbating her softly until she woke. She looked back at me and smiled. "You don't stop, do you?" she said half laughing and half moaning.

"Do you want me to?" I retorted.

"Never!" she affirmed.

We kept it relatively quick this time. We didn't have the energy for another session like the night before. I got her off just by rubbing her clit and kissing her neck. She repaid the favor by eating me out. We lay in bed for a few minutes and enjoyed each other's company.

We hopped into the shower together and scrubbed each other clean. As she started soaping up my tits, I felt myself getting excited again. "Would you mind getting me off one more time, Jen? When you touch my tits, my pussy instantly gets wet." I told her.

"Good to know." she said before finger-fucking me. I had a lovely little orgasm. Then she asked me to get her to cum too. Eventually we made it out of the shower and dried off. Jenny sat at the table to dry her hair. I straddled her and looked her in the eyes. "I really love you." I told her. "As my sister and my fuck-buddy. I don't what this is going to be going forward. I mean, we're not dating or anything sick like that. I just want to have fun with my favorite person on Earth. And if it gets too much or you get bored, just tell me and we'll stop it. We can go back to being regular sister who don't screw each other's brains out."

"Sounds good to me." she said with a heartfelt tone.

I lingered there for a moment looking into her eyes. Then I started emptying my bladder on to her lap.

"Are you fucking serious, Ash? I just got clean."

"Did you?" I asked sarcastically as I stood up and showered her tits making sure she was drenched. "Oh and won't you look at the time. We need to check out now!" I said cheekily.

We quickly left the room having thrown some towels on the floor to soak up as much of the mess we'd left there. Jenny then had to walk around the city with nothing but a trench coat and boots, completely covered in my piss. My pussy maintained a nice level of wetness at the thought as we rode the bus home together. We exchanged glances throughout the ride at the night we'd just had and the state that my sister found herself in.

And that was the second time my sister and I fucked each other. It was probably the turning point where we threw out all the rules and became the freakish sluts we are.
