As Kelly and Sandra enjoyed a passionate kiss, tinged with the taste of my man-juice, I realized I hadn't tasted Kelly's pussy in quite some time. I decided to end that drought right away. I slid down the bed and lowered my head between Kelly's legs. I started slowly licking her outer lips very softly, noticing the tremendously musky, yet sweet scent leaking from her nether regions. Her bare pussy was so smooth and soft as my tongue delved deeper, tracing the outline of her inner lips.
As I tasted Kelly's lower lips, my sister tasted the lips of her mouth as they continued their make-out session. The assault on Kelly's senses was almost overwhelming as she fell back on the bed and spread her legs wider, providing me easier access. As I continued to lavish attention on Kelly's pussy, Sandra was massaging Kelly's firm, taut breasts. Sandra was beginning to suck on Kelly's tits, causing Kelly to arch her back and moan in pleasure.
"Ooh, that feels so good". "Don't stop". "Don't stop". Kelly commanded as me and my sibling tongued some of her most sensitive areas.
Just then I noticed that Sandra began moving down Kelly's body. Tracing her tongue across Kelly's flat belly, circling her navel with kisses, and continuing down, placing soft kisses on Kelly's hip bone. Before long Sandra was laying next to me, her torso straddling Kelly's right leg and she moved her face next to mine.
"Kiss me bro. I want to taste Kelly on your lips", Sandra panted.
With that, I leaned into my sister and pressed my lips to hers. Our mouths opened and our tongues met in a frenetic dance within our mouths. As we kissed, Sandra slipped her index finger into Kelly's tight pussy and began massaging Kelly's G-spot, just inside and near the top of her pussy. Kelly's hips were thrusting to meet the motion of first one and then two of Sandra's fingers.
Within a few seconds, Kelly let out a scream: "I'm CUMMMMING!!!!" as juices gushed forth from her pussy.
I quickly disengaged from my sister's mouth and began lapping up Kelly's juices which were liberally distributed across her inner thighs and all around her pussy. Once I had cleaned up her juices, I slid up Kelly's body, leaving a trail of kisses from her clit to her chin. As our lips met in a soft kiss, I could feel my now hard cock brushing against Kelly's other set of lips.
"Mmm-hmmm" Kelly moaned as I began slowly sliding my cock into her pussy. "Yeeesss" she called out as the tip of my cock pressed against her cervix and my balls were flat against her tight asshole.
Kelly's legs were wrapped tightly around the small of my back as we rocked back and forth in a slow, languid motion. I was completely engulfed in what I was doing with Kelly that I had almost forgotten my sister, when all of a sudden I felt something wet and warm slide across my puckered bum. I turned my head and saw that my sister was kneeling behind me, giving my balloon knot a nice tongue bath.
I had never had anybody lick my butthole before, and I have to admit that the sensation was spectacular. I could feel my cock getting bigger and bigger as Sandra lapped at my ass. It was a wonderful mixture of sensations as Kelly's sugar walls massaged my cock and my sister's tongue slid back and forth across my backdoor.
My sister's saliva was covering my crack from top to bottom as I began to pick up the pace of my strokes inside of Kelly's cunt. Kelly was begging me to fuck her harder as I continued my long, deep strokes into her steamy slit.
I could tell we were both close to orgasm as Kelly's breathing was becoming ragged, and my balls were beginning to tighten. I thought I might have another 10 or 15 strokes in me when all of a sudden, I felt my sister slide her index finger into my well-lubed bunghole. At first I tightened up, but quickly I relaxed as I adapted to the feeling.
Before I knew it, my balls felt as if they were exploding and I shot the hugest load of my life deep into Kelly's pussy. I could feel it splashing deep inside her, and backwashing out around my cock and down my balls.
"Aaarrgghh", I cried out as I had the most intense orgasm of my life, collapsing upon Kelly as her own body thrashed in the throes of her own climax.
"What did you do to me?" I asked Sandra as soon as I recovered from my orgasm.
She looked at me with a shit-eating grin and said that she simply stimulated my prostate. "Was that the first time a woman's done that for you?" she asked
"Yes", I replied.
"I'm amazed" Sandra said. "I thought that all men knew that stimulating their prostates gives them more powerful orgasms".
"Well, it's news to me" I said. "I'm certainly never going to forget it though, after what I just felt".
I rolled off of Kelly and lay in between her and my sister, trying to recover all of my senses. I could hear their soft rhythmic breathing, and I knew they were both asleep. I decided that after a long day of work and a couple hours of fucking, I desperately needed a shower. I slowly and quietly slipped off the bed and padded down the hall to the bathroom where I closed the door and turned on the shower. I slipped inside and stepped under the warm spray of water, letting it course through my hair, and over my face. As I soaped myself up, I began replaying in my mind what had just happened, and before I knew it my flaccid cock was rising to the occasion again. Knowing that with these two hot women in my house for the next couple of days, I needed to use my tool only to please them. I let go of my shaft, turned off the water and stepped out of the shower.
I walked back down the hall with my semi-erect penis swinging back and forth in front of me. As I turned the corner in to the bedroom, I saw Sandra laying on her back, spread-eagle in the middle of the bed. I then saw Kelly standing over one of their bags, and she quickly gave me the "shh" sign with her finger in front of her mouth.
It seemed that Kelly had already found my tie rack and had used a couple of my silk ties to bind my sister's hands to two of the four posts of the bed. Sandra had always been a sound sleeper as a kid, and apparently that had not changed. She was breathing deeply, and apparently didn't realize that she was tied to her little brother's bed. When Kelly stood up, she had a sleeping mask in her hands, and tip-toed over to the bed with it. She gently slipped the strap behind my sister's sleeping head, and placed the mask over her eyes.
Kelly went back to her bag and withdrew a few more items: a long feather, a hot pink gel dildo, a bottle of astro-glide, and a harness. Kelly put the dildo into the harness, and then strapped the harness around her waist. She then handed me the flower and with hand motions instructed me to lightly draw the feather across Sandra's skin.
I drew the feather across my sister's hips and she moved slightly but didn't wake up. I tickled down the length of her thigh, to her knee, across her shin, and lightly brushed the feather across the bottom of her foot. When the feather hit her foot she kicked her foot a little and seemed to begin to wake up. At that same time, Kelly leaned across Sandra body and gently sucked one of her magnificent nipples into her mouth.
Sandra's body jerked at Kelly's touch, but she didn't say a word. It was evident to me that Kelly and Sandra had played this little game before.
As Kelly continued to gently suckle Sandra's nipple, and continued to explore Sandra's body with the feather. I brought it back up her leg, across her inner thigh, and had it lightly brush her now protruding clit.
When it touched her clit, Sandra was unable to control herself and let out a soft "ooh" sound.
