I peeked in the crack again, and saw something that blew my mind. My sister was completely naked, moaning loudly, arching her back in pleasure as Bridget drove her fingers in and out of her and sucked on her breast. This gave me a massive hard-on, of course, and I shifted my pants as I watched them continue to go at it.
Bridget's pale fingers continued to piston in and out of my sister's thin, tan body as Emily thrust back at her. Bridget's red hair cascaded over Emily's stomach as she kissed down her body. Bridget's hair hid her face, but I knew she had hit the sweet spot by the way Emily suddenly screamed out in pleasure.
Emily grabbed her own breasts now, her body still thrusting in pleasure. "Ohmigod, Ohmigod" she moaned, and I could her the 'slap-slap' of her crotch against Bridget's hand. Suddenly she stopped screaming, and her body thrust spastically as she came. Bridget stopped, and kissed her way back up Emily. Their faces met, and Bridget let Emily taste her own juices. Emily moaned again, and I heard Bridget ask her to return the favor. Emily seemed hesitant, but a few rubs of Bridget's hand on her bare pussy persuaded Emily to go down on her. Emily moved off the bed, her ass sticking out towards me.
I could see how the wetness had dribbled out from her pussy onto her legs, and how red and puffy her lips were. Bridget was facing me now, as Emily sucked on her nipples. I had pushed the door open enough that I could see with two eyes, and Bridget looked up now, and smiled at me. I put my finger to her lips to 'shh' her, and she nodded, as Emily pushed her onto her back. Bridget's legs were spread wide, and I ducked down to watch my sister go down on another girl.
It was obvious this was Emily's first time doing this, but Bridget encouraged her, and soon Em was chowing away like a pro. Bridget pulled her legs out, spreading herself wide open, and I watched Emily stick one finger in her, then two, then three fingers into her, as her mouth clamped down on Bridget's clit. Bridget writhed about now, her body spasming in pleasure. She moaned "Yes, that's it, faster, yes, please, yes" then bit her lip, and I saw her start to cum. Emily was unsure what to do, but Bridget pulled her head into her crotch, and Emily attempted to keep up with the wetness that pulled from the redhead's pussy. When she was done, they began to kiss again. Bridget rolled Emily over onto her back, and began to finger her again. Emily was worked up again, and started to respond to Bridget's touch.
Bridget then turned towards me, and motioned me to come into the room. I shook my head 'no,' but she kept insisting, and finally, I slowly pulled the door open and crept in. Bridget moved over and stuck her crotch in Emily's face so she couldn't see, then motioned for me to eat Emily out. Up until the 'naked run' night, the thought of touching my own sister would have disgusted me, but after watching her '69' with my semi-girlfriend, my dick was doing the thinking.
I moved in, and kissed Emily's inner thighs lightly. I then moved closer and closer to her pussy. I felt Bridget's finger on my chin, and looked up to see her smiling at me. I leaned in and kissed her, giving me my first taste of my sister. She then broke the kiss, and pointing me back to the wonderfully bare pussy in front of me. I leaned down, and slowly licked around Emily's lips, then up and down them, before finally sticking my finger between them as I nibbled on her clit. I heard Emily moan into Bridget's pussy as I worked on her pussy, my tongue and fingers alternating back and forth between her clit and pussy. She began to moisten more and more, and I heard her moaning more into Bridget's pussy and licking less. Finally, Bridget sat up, moving away from Emily's face. Emily was too far gone to notice, and began to moan louder and louder as I worked my full magic on her. Finally, she began to cum, and I sucked down my sister's sweet nectar as it spilled out onto my face.
As she came down from the orgasm, I saw her begin to realize that it wasn't Bridget doing the licking. She sat up suddenly, and saw me kneeling there, my face covered in her juices. I smiled, and I saw her face alternate between shock and awe. Finally, Bridget spoke:
"Emmy, isn't he so good at that? I just had to show you."
My sister nodded, still staring me in the eyes.
"You should feel his cock. It's the biggest thing I've ever taken. You have to try it."
"I – I don't know, Bridget." I could see Emily was a little freaked out by what had just happened. After all, she had just had her first lesbian experience and been eaten out by her brother one right after another.
"Ok, fine then. How about this? I'll take it out and play with it, and you jump in when you feel comfortable." Bridget was determined to make this happen, I guess.
As my sister lay back on the couch, Bridget moved over towards me and began to kiss me. I could smell the aura of pussy in the room, and tasted it on Bridget's mouth. The taste of my sister's forbidden cunt, which I too had just sampled.
Bridget quickly began to rip off my clothes as she continued to kiss me. In no time at all, I was down to just my boxers, which her hand had found its way into. I groaned as she pulled my cock out and began to jerk it. Bridget then began to kiss down my body, her hand pistoning up and down.
I looked over to see Emily rubbing her own pussy with one hand, while the other massaged her breast. I smiled at her, and she smiled back, tweaking a nipple in front of me. At that point, Bridget's lips touched my cock, and I closed my eyes in pleasure.
Bridget was quite an accomplished cock-sucker, and she had pull out all the stops tonight. I'd never felt anything like what she was doing to me, as she ran her lips up and down my cock, her lips tracing lines around me. I looked down and saw her curly red hair bouncing up and down in time with her neck movements. She looked up at me, and smiled around my cock, before pushing her nose against my stomach in an exquisite deep throat.
I came out of my trance long enough to check on Emily. The sight of this curvy redhead attempting to give my penis CPR had apparently gotten her pretty worked up, as she now had 2 fingers deep inside her own cunt. It hit me then that I had never realize what a fantastic body my sister had until now. She had one of those lithe, athletic bodies like Jennifer Garner, and a great rack with no sagl. Her long, tan legs were spread out almost into a split as she fingered herself.
Bridget had taken me out of her mouth, and began to suck on my balls as she jerked me. I ran my hand through her hair, and she smiled up at me, then looked over at Emily. Her hand continued to run up and down my dick as she asked my sister: "Do you want to try? He tastes wonderful."
Emily bit her lip as she looked at Bridget, then nodded. She crawled down the bed to where I was standing as Bridget moved over to make room. Emily took over jerking duties, then leaned over and lightly kissed the tip of my cock By this point I was reaching the boiling point as I now had 2 beautiful girls working to get me off, but I held back, wanting to feel more of my sister's touch.
Emily kissed my cock lightly a few more times, then took it in her mouth. Bridget was watching hungrily, tweaking both her own and Emily's nipples, and smiling up at me. Emily took most of my cock in her mouth, running her tongue around my length on the inside. She began to bob back and forth, her black hair back in a ponytail. Bridget spread my legs and got beneath me, sucking in my balls. I knew I wouldn't last much longer, and told the girls so. Emily pulled out her meatsicle, and looked up at me:
"Dylan, will you come in my mouth? I want to taste you."
I froze, then nodded, surprised by how forward my sister was being. She then sucked me back in and began to double her speed. It felt fantastic, and soon I felt a deep rumbling. I grunted and tensed up, and Emily pulled my cock out and began to jerk it, aiming it at her mouth.
I let myself go, and watched my cum shoot out. The first shot went high and hit Emily in the nose and cheek, but she took just the tip in her mouth, and sucked up the rest. When I finished, she showed me my seed in her mouth, then Bridget came over, and started to clean off my still-sensitive cock. She then turned to Emily, and ran a finger over her face where the cum line was. Emily greedily took this finger in her mouth, swallowing the last of my spunk.
The girls then kissed, and looked up at me:
