While Her Sister Watched Pt 04

The day after I shot cum onto my girlfriend's younger sister I woke up early, or rather, got up early after a restless night. Anna had come home in the early morning hours and I feigned being asleep as my heart pounded with nervousness.

Once the clock read a semi-reasonable time to be up and about I slunk through the apartment as quietly as possible to the kitchen. I putzed around in the kitchen making coffee and putting together some breakfast for everyone.

As I was putting plates and coffee mugs onto the table I looked up and saw Amalia standing in the doorway.

"Good morning," she said as I stared open-mouthed at her nude form. She had placed her arms on the sides of the door frame showing off her toned athlete's body.

When my eyes could finally focus again I looked closer and thought I could see that she hadn't cleaned all of my cum off of her chest and shoulder, at least not all of it.

A closed-mouth chuckle was the response she gave to my silence before she gracefully stepped up to the table I was setting. She stuck her middle two fingers into the open container of strawberry jam, moaned the same way she did the night before, pulled them out, and stuck both fingers slowly into her mouth down to her third knuckle, moaning again. She pulled out her fingers with a pop and bounced off back to the bedroom across the hall and shut the door. I stared down at my tented trousers and debated making a pitstop to the bathroom before I shook my head and turned back to breakfast.

Ana came into the kitchen just after I was able to tame the beast between my legs through willpower I didn't know I had.

"Good morning," she said and stood on her toes to kiss my lips. "How was last night? You were both asleep by the time I got home"

My heart pounded in my chest.

"It was chill, I got home a little late from work so...you know"

My phone went off, thankful for the distraction I pulled it out of my pocket.

"Ah shit, I forgot that Mattias gave us tickets to that show tonight," I said

"Damnit, I'll be working late again tonight. I forgot about that" Ana said "Maybe take Amalia with you! That would be a lot of fun for her I think!"

"Oh, yeah...ok. We'll ask her when she gets up."

"I would love to go out with you tonight," she said as she floated into the kitchen, wearing clothes and a sexy smirk.

"Watch yourself now, he's mine!" Ana said with feigned anger and a pointed finger.

"I don't see your name on him anywhere."

"I'm booking a tattoo appointment for you asap." She giggled "I think 'ANA' would look great on your left butt cheek...or maybe your forehead!" Both sisters broke out in laughter and I smiled and swallowed the lump in my throat.

...

I checked the pockets on my trousers for the important things for a third time - phone, keys, wallet, nicotine. I fixed my hair one more time then decided to just throw a hat on anyway.

"Are you ready?" I called out to the spare bedroom.

"I've been ready" Amalia answered back and stepped out of the room.

She was wearing black jean shorts that fit tightly to her muscular thighs, the black nylon tights she wore under those did little to hide the smooth paleness of her legs. A shiny rose gold top she wore with the top few buttons undone teased the black lace bra that covered those small perky tits I now knew.

It was a short walk to the student union building where the concert was held. We took the direct route and walked through the concrete canyon of the main road that my apartment sat along.

At the door, the bouncer checked our IDs and let Amalia know that she was only allowed in certain parts of the building. Some areas were eighteen and over and others were twenty and over, depending on the type of alcohol that was being served.

"Should we get a beer first?" I practically shouted over the loud music as we walked into the concert hall.

Amalia nodded her head yes and gave me an appreciative smile when I paid for both drinks.

"I don't usually drink, but tonight's a good night for a beer I think" she shouted back at me.

The line at the bar was long, but they were efficient. When I turned back with a beer in each hand I saw Amalia chatting animatedly with another girl. Shorter and stouter than Amalia, with a tan complexion, brown hair, and much bigger breasts she showed off with a tight, low-cut top.

"Hello," I said and handed a beer to Amalia.

"This is my friend Charlotte, we play football together."

"Oh cool, I'm..."

"I know who you are" she cut me off with a massive smile that made her green eyes sparkle.

I wasn't sure what she meant by that, but I didn't need to answer as the lights changed and the first guitar notes erupted from the speakers overhead. The first band walked out onto the stage and we inched into the crowd towards the stage. Through the disorganized press of bodies, Amalia ended up in front of me. I put a hand on her hip to let her know I was still with her. She turned her head and beamed a smile at me with perfect white teeth through lush pink lips. If I'd had another beer or two in me I may have acted on the urge to lean forward and kiss them. I looked around and didn't see her friend we'd been talking to a moment ago.

My head snapped forward again as the band broke into their first song and I could feel Amalia pressing her ass into my crotch, lightly at first that it could have been an accident, but then she started moving it with the music. I could feel those tight mounds gliding back and forth and up and down across the front of my hips and my crotch.

After a few songs of this and being jostled around with the rest of the crowd a slower song started and as the lights came down a little more to match the vibe. That's when I felt Amalia's hand reaching back a little to first press her fingers onto my hip, she adjusted her aim and I felt them again press into my semi-erect cock.

"Should we get some fresh air?" I said into her ear. To which she just nodded. I took her by the hand to not lose her as we wove our way through the crowd.

"Follow me, I'll show you something cool," I told her.

The smile she gave me would have melted the heart of any man.

...

"Duck your head," I said as I helped her clamber through the window, both of my hands on her waist this time. Once she steadied herself she turned and offered a hand back through to help me. I grabbed it and her skin felt cool and soft and clean.

"How did you know about this place?" She asked as she stepped to the concrete railing. The lights of the city reflected brightly in the shallow pools of her light blue eyes. She looked stunning, her light-colored hair and pale skin illuminated in soft orange light.

"I grew up here and we used to sneak into the building all the time when we were underage and bored. It led to some exploring.

"Ah a bad boy, you are my sister's type then."

"Oh, she was into bad boys growing up?"

"You should have seen some of the clowns she brought home. My parents never approved...until you" she laughed.

"What are you into then?" I asked, feeling brave

"The same as my sister" she turned to me "So why did you bring me up here?"

I didn't have an answer.

"Don't worry, I'm not going to tell Anna. She would hate me forever. Even though we're sisters and we've always shared..." She twirled her long blonde hair through slender fingers.

"Exactly, the Snapchats and watching each other was one thing already this is..." I couldn't finish the sentence as she rushed forward and grabbed the back of my head with one hand and pulled me down so our lips met.

Sparks.

Any hesitation, anxiety, and shame melted away the moment I felt her tongue push past my lips and curled with my own.

I grabbed her ass firmly with both hands and breathed in shapely at finally touching that perfect ass, it felt as good as it looked. Both cheeks big enough to wrap your hands around, firm but supple.

Our tongues continued to twist and explore each other's mouths. Amalia's hand settled on the front of my jeans and finished the job her ass started in getting my cock hard as a rock. She gently rubbed her palm up and down, the feeling of her hand and the fabric sent shivers down my spine.

With one hand I unbuttoned her shorts and slid them down her smooth skin to slide between her legs. My fingers found a pool of her sex as she quivered with anticipation of my touch. I held still and savored the feel of my girlfriend's little sister's smooth teenage pussy as it folded around my fingers. A few more tongue tassels and I started to glide my finger up, down, and around her soaking slit. I pressed my middle finger gently into her. She was so wet but so tight and I had to press a little hard to get the tip of my finger through her entrance. Just one knuckle deep and I could feel her walls tighten and relax, tighten and relax.

My cock hardened even more and tightened the left leg of my trousers around it. As we continued to let our tongues explore each other I unbuttoned her shirt with my other hand and cupped her small breast through the black lace. The texture on my fingers and palm sent small jolts of lightning to my groin, and my cock pulsed over and over.

Finally, I separated from her, I held her at arm's length and my eyes drank her in. Blonde hair tousled, her shirt unbuttoned to her waist, and the lace bra that just hinted at pale breasts and pink nipples underneath.

Gently, I turned her around and bent her slightly over the railing so she looked out onto the lights of downtown reflecting off the river. I pulled her pants down and she stepped gracefully out of them when they reached her ankles. She leaned forward on her elbows and gave me an even better view, her round ass pale as the moon, a tight pink asshole and flushed slit presented towards me.

I dove in and licked her pussy from front to back and the moan and girlish squeaks she made encouraged me to continue. My tongue exploring, tasting, spoiling her. The next squeal came when my tongue swirled into her tight asshole was almost too much for me.

After a few minutes of me pressed face-first into her from the back she turned around and gave me better access to the sensitive parts of her. I kissed and lapped at the smooth skin around her panty line and down to her thighs before I reached one hand up and pushed fingers back inside of her. She clapped a hand to her mouth to muffle the scream she made. She followed with a moan, her hand lowered to tense and pull at my hair, the other raised to squeeze one small breast through her shirt. Her legs quivered as she let out one last yell.

We waited a moment and looked around, just remembering we were in a public space. No one down below seemed to be able to see us or hear us and no one had come up to this secret spot for a smoke or anything.

"Holy shit." Amalia gasped at last and breathed in deeply before she ran both her hands through her hair. "No fucking wonder..." She trailed off

I stood up with a smile and she stepped forward, wrapped both arms around my neck, and pulled me in to kiss deeply. Her tongue explored the inside of my mouth as well as the outside as she licked and sucked her own juices from my soaked lips and my chin.

When we parted after what felt like both a lifetime and only a second I had to run the back of my hand across my face to wipe away her spit and pussy juice. She used both hands to undo my belt and unbutton my trouser and, without hesitation, she pulled them down to spring free my hard cock. It bounced between us in the cool night air and I watched her eyes widen and her cheeks flush even more as she reached a hand out.

Her hand was even softer than I expected. It was pale and small, despite her long fingers, and made me feel like I had the biggest dick in the world when I looked to see them wrapped around my shaft. For a time she just held my cock in her hand as we made out again. After we tied a few knots with our tongues she started to stroke lightly, running her hand up and down from the tip to the base.

"Your hand feels so good on my cock" I said and leaned my head back. "Have you done anything like this before?" I asked

"I gave a handjob before, kind of."

"Really? That's all?"

"Yeah...why am I hurting you?"

"No, it feels amazing."

"Good, but I want to try something else" She took her hand off my member, and when I opened my eyes I saw the top of her blonde head down in front of me. It sunk in then that my girlfriend's teenage sister was on her knees in front of me, ready to suck my cock.

She didn't hesitate. She gripped the base of my cock with her right hand and she leaned forward. First, she explored the head of my cock with her lips and her tongue. Giving me gentle kisses and small licks. She pulled her head back and I watched a string of precum and saliva stretch between us, tethering her lips to my cock.

I saw her smile before she leaned forward with an open mouth. Warmth spread from my cock to the top of my head as she wrapped her lips around me and slid forward, inching towards the base.

I let out a grown and just as I felt content with how far my cock had pushed into her mouth she backed off until just the tip was still covered by her lips. I exhaled sharply as I felt her teeth clamped lightly into the soft skin of the head of my cock, then as her tongue pressed and twirled around the tip. At the perfect moment as my pleasure peaked, she pressed her head forward again and swallowed my sword.

"I'm going to cum soon," I told her and ran my fingers lightly through the hair on the side of her head. She made a popping noise as she pulled my cock from her suctioning lips and gave my frenulum a lick.

"You've really never done this before?" I asked her as my balls began to tighten and tingle, wanting to release into this blonde teenager's mouth.

"I've watched a lot of videos." She said and gave another lick. "That reminds me..."

She pulled out her phone and started filming herself and taking photos. I'm pretty sure she even recorded a Snapchat of her kissing my head, running her tongue in circles around it, gently slapping herself on her cheeks with my cock with wet, meaty slaps.

She could have been doing anything at that moment and I wouldn't have cared as long as she kept those soft pink lips wrapped around my cock.

The phone went away and she immediately went back to work. Her head bobbed up and down.

I put my hands on the cement railing and stared off at the lights of the city, the view was spectacular but I was unable to focus on anything other than the warm soft teenage mouth pleasuring me.

I moved one of her hands down to the base of my cock and the other I pressed around my balls. She read what I wanted and gave my balls a gentle squeeze and started stroking my cock with her hand along with her lips.

"You're going to make me cum" I groaned.

"I want it in my mouth, like you did to my sister." She said after taking my cock out of her mouth and immediately dove back onto my throbbing member, taking it in almost to the base before gagging some. She pulled it back out and stroked me with one hand. "It was so hot watching you shoot cum into her mouth, your face when you came was amazing."

She deep-throated me again and gagged a little again but she kept it in her mouth that time and began to bob up and down faster and faster.

"Fuck, fuck, fuck" was all I could manage before that familiar feeling spread from the bottom of my feet to the base of my skull.

I put a hand on the side of her head and gently held her in place while my hips rocked back and forth to bring me over the line.

I held my cock as deep as I could as the first waves of my orgasm crashed over me and tumbled me around in its depths. One rope, two ropes, and I backed my cock out slightly and filled Ana's little sister's mouth with so much cum. She pulled her mouth off of my cock and cum cascaded from her open mouth to drip down her chin, onto her shirt, and her legs. Two more ropes of sticky white erupted from the end of my cock -- one landing in her hair, another hitting her forehead and sliding down to her eyebrow.

She sat back on her heels, opened her eyes, and looked straight into mine before swallowing the cum that remained in her mouth with an exaggerated movement. She opened her mouth and stuck out her tongue as if she needed to prove what she'd just done to me.

"Fuck" I said again as I looked down at my girlfriend's little sister, still on her knees and covered in my cum again.

...

We walked back to my apartment along the river hand in hand. She ran her hand over the front of my pants a few times and we stopped in the shadows of trees to make out a few times.

When we walked into the apartment the lights were on.

I didn't realize how late it was.

"Hey guys! How was the show?" Ana's voice called out from the kitchen. She stepped out to stand in the doorway, "What happened to your clothes?" She asked her sister.

Amalia looked down at the wet mess my cum and her saliva had made of her shirt.

"Oh, I spilled my drink on it." She said without hesitation "I'm going to go get changed" Amalia said, flashed her sister one of her huge smiles, and made a B-line for the bedroom.
