While Her Sister Watched

"Good morning." Ana's voice drifted into me through the heady haze of light sleep. Another restless night lying next to my girlfriend after cumming on her little sister the night before. I pulled my eyes open and rolled over in the bed to see her standing in the middle of our room with her heavy grey bathrobe on.

"I have a surprise for you," Ana said as she dropped her robe to the ground, she wore a classic set of black lingerie. Bra, panties, a garter belt, and thigh-high stockings. She looked incredible, the black lace with a subtle floral motif on the bra cups and panties, and even the nylon stockings stood out from her pale skin.

"I told you I'd make it up to you."

"Make what up?"

"For having to spend time with my sister while I had to work this weekend." She smiled at me "She said you made it a very fun weekend.

I was lost for words as I thought about what I'd been doing with her sister all weekend, and also as my eyes took in the sight of Ana in front of me.

The bra pushed up her small tits generously to give her an extra bit of cleavage. The material stopped just over the top of her light, pink nipples. The thigh-high stockings attached to the garter belt set me off the most. Her pale slender legs looked perfect.

"There's a few more accessories, I thought I'd let you choose." She said and presented me with a small, open box

Inside the box were a number of items that ranged from innocuous to obscene - most of which I had seen and used before, but there were new items in there. I pulled out a thin strip of black velvet and handcuffs made of pink faux leather with a golden chain.

"Oh, keeping it classic this morning. I like it" she said to me and reached down to pull me up off the bed.

We flowed into each other immediately. Our lips locking and tongues tying. I ran my hands all over her body, the change in texture from smooth skin to the grabbing nylon to the smooth lace sent jolts through my spine.

We finally separated and I brought up the blindfold to secure it tightly over her eyes before I spun her around brought her wrists together at the small of her back and secured them with the handcuffs. I guided her over to the bed.

"Get on your knees there and wait for me" I commanded

"Ohh, bossy, this keeps getting better," She said with a toothy grin.

I grabbed my phone and turned on our Bluetooth speaker to set the mood a little. I was just about to select some music when an idea came to me. I opened up Snapchat and took a picture of Ana on her knees on top of our bed, her arms handcuffed behind her back. One strap from her bra had fallen off her shoulder and revealed more than just a hint of nipple.

I looked down at the picture, Ana looked so sexy in it. Her pale skin glowed almost blue in the morning light that slipped through our curtains. "Come watch," I wrote over the image.

I hesitated.

"Hurry up," Ana whined.

Fuck it, I pressed send and could hear my heart pound in my chest.

The Snapchat went to seen before I closed the app.

I swallowed the lump in my throat selected some music and set it to play from the small speaker we kept in the bedroom. I put the volume up just enough that Ana couldn't hear me as I walked across the room and opened the door to the hallway.

Outside of our room, the apartment was quiet, the blue-grey light of early morning spilled out of the kitchen door onto the wood floor. I waited a few beats, hoping to see the door down the hall open. I closed the door halfway again and turned back into the room and with my hands on her shoulder I gently lowered Ana to her knees with her back to the door. I put one hand on the back of her head and used the other to guide my cock into her open mouth.

Ana pressed her head forward and I felt her lips bottom out on my cock. She pushed her tongue out over her bottom lip and gave my scrotum a teasing lick.

"I fucking love it when you do that," I said to her. She smiled as she backed her head off of my cock and then plunged forward again. I held her head there and looked up as the door to our bedroom swung silently inward.

Amalia stood in the open door in an almost identical set of lingerie as her older sister - sans the thigh-high stockings. Sheer black lace did little to hide the small pink nipples that sat centered on her a-cup breasts and the smooth skin that led down to her sex. My mouth watered a little as I remembered the way that teen pussy tasted.

Still holding Ana's head to keep my cock in her throat I turned slightly to give Amalia a side-on view of how deep her older sister could take my cock. She put a hand to her mouth in surprise and her face and chest flushed pink.

I pulled my hand off the back of Ana's head.

"Show me what that cute little mouth can do," I said to her, still looking at her sister in the doorway.

Ana always sucked cock with enthusiasm, and this time she seemed to find some more. She soaked my cock with her spit as she slid her lips up and down my shaft, swirling her tongue and biting playfully at the tip. She took my cock into her throat and stuck her tongue out again to tease my balls.

I pulled my cock out of her throat and brought Ana up by her hands and pushed her gently forward so she flopped onto the bed on her stomach with her pale legs spread. With both hands, I picked her up by her hips into a doggy position and pressed the head of my cock into her entrance. I slid in easily and held myself pressed in as deep as possible. She moaned and writhed her hips.

With my right hand, I grabbed the golden chain that linked her wrists together and used that to pull her ass back onto me as I fucked her - pounding my cock deep into her pussy harder and harder with each stroke until she had to push her face into the mattress as she moaned and squealed loudly.

I looked to my left and watched as Amalia quivered and put a hand over her mouth to stifle her own noises. Her other hand rubbed hungrily at her clit and her hips rocked forward and back.

She came watching her sister's body ripple and shake as my cock pounded into her.

Watching Amalia bring herself to the peak of her pleasure and the feeling of Ana's warmth gripping my cock pushed me to the brink. My balls began to tighten and lightning coursed through my body, starting at the soles of my feet and traveling to the base of my skull.

"Where do you want me to cum" I asked and looked Amalia in the eyes.

"Cum wherever you want, baby" Ana replied as I continued to thrust into her. "Oh, fuck"

Amalia's smile stretched across her round face before she scrunched her face and brought a hand to her chin, miming hard thinking. I gave her a pleading look as I could feel my groin start to tingle and my balls tighten.

She pointed to her face.

I pushed my cock into Ana as deep as I could one last time and held it there for a moment before I pulled it out completely and took a step back.

"Get on your knees," I told her and took her hand to guide her to the floor again.

I lifted my cock to give her mouth access to my balls and pulled her head forward. I felt my balls slap lightly into her chin before she took them into her mouth hungrily, sucking and swirling them with her tongue. I started to stroke myself and stepped back slightly so that the tip of my cock was centered on Ana's face and just centimeters away. I looked over at Amalia, her chest still heaved as she recovered from her orgasm.

Amalia glided over silently pushed my hand out of the way and replaced it with her own. She didn't miss a beat as she gripped my shaft firmly and stroked at the same speed as I had been. Her sister's spit and pussy juice coated her hand as she glided it smoothly from base to tip.

Up and down up and down, twisting her wrist slightly to put the right amount of tension on my throbbing cock.

She put a hand on my lower back and pulled me forward, guiding my cock forward to meet with her sister's lips once again. Ana gave the head of my cock a kiss before her lips parted and she swallowed me whole. Amalia's fingers and Ana's lips touched lightly. The visual alone was more than I could take.

"I'm fucking cumming" I blurted out and immediately felt the pressure well up in my balls. Amalia was quick, she pulled me out of her sister's mouth and began to pump my cock firmly.

Up, down, up, down - her grip tightened and I came like a fountain. Guided by Amalia's soft hand I sprayed Ana's face with thick rope after thick rope of cum.

I barely kept my feet as I surfed the waves of pleasure Amalia's soft pale hand pulled out of me and onto her sister's blindfolded face. I put broad stripes of white across the black blindfold and Ana's pale cheeks, and soft, pink lips.

The last string of cum didn't stop my cock from pulsing in Amalia's grip. She smiled up at me and raised one eyebrow before using her pointer finger to wipe the vestigial drop of cum from the tip of my cock. She raised the finger to her open mouth and pressed the cum covered tip onto her tongue.

"Oh my fucking god, that's so much cum" Ana breathed heavily and reached up to remove the blindfold.

I panicked.

"No, no, leave it on for just a minute," I said and clasped her wrists "You look so fucking hot right now." She smiled up at me sat back on her heels and waited patiently.

"Stay there. Just like that, I want to take a picture." I said and stepped back. I felt the warmth of Amalia's naked body at my side as she wrapped her arms around me and put her head on my shoulder.

"That was so fucking hot. I can't wait for my turn," she whispered into my ear before she bent at the waist and took my, still rock hard, cock into her mouth, bobbed one, twice, thrice before she stood back up, smiled, and stalked silently out of the room.
