I Caught My Sister Muff Diving Ch. 02

Some summer break, huh! I was on my knees, my fast shrinking cock sharing space with the load of cum I’d just pumped in to Julie’s vagina. And, I was grinning down at her best friend, who just happened to be my apparently utterly uninhibited, and right then anyway, supremely satisfied looking sister Tracy! And why not; after all, the girlfriend with the pussy full of cum had just licked and finger banged her through more orgasms then I would have believed any one girl could have!

Earlier, when a night out with my buddies had turned boring, I cut it short, and headed for home. And that just might have been the best decision of my young life! Back at home, and after a swim, I was headed for a shower, and that’s when I over heard my sister trying to talk Julie in to some playful girl-on-girl experimentation. So, from a spot in the hall, I watched in the bedroom’s mirrored closet doors, while my muff-diving sister discovered the thrills and joys of munching on a little pussy! Catching on fast, she quickly had a reluctant Julie screaming, and even begging for more! Well I got caught, and of course with my dick in my hand! But luckily the girls didn’t freak, Julie barely even blushed, and it looked to me like my sister actually got a kick out of it. Anyway, Julie kept shying away, refusing to return the favor and go down on Tracy. But when Tracy caught her staring at my hard-on, she teased her until she agreed to go down on me instead. Only as good on the old skin flute as Julie was, she just couldn’t manage to deep throat me! And when my smartass sister wouldn’t stop razzing her, Julie finally told her to put up or shut up! Well daring my sister is dangerous, and Julie compounded her error by agreeing to try pussy, if Tracy actually had the balls to go down on her brother! And who knew; but, it turned out exploding cum in to my sister’s mouth was a real turn-on!

Anyway, after I pulled out of Julie, I flopped on to my back, tuning out the giggles and their back and forth chatter. But my ears pricked up, when I heard Julie say “Oh really, well smarty, maybe you’d like another helping of Robby’s cum! Yeah, and it just so happens that I know just where you can get some too! Un-huh, and I can even deliver it with a side of that pussy you enjoyed so much too!”

Playing it safe, I was already on my feet, when Tracy challenged “Deliver…oh really?” And it was on! Shrieking and squealing, they wrestled, tickling, pinching, and even sneaking in the occasional kiss! Well I figure Tracy took a dive; otherwise, no way would Julie have ended up sitting on her face! And pretty quick, Julie’s giggles had turned in to panted gasps! Yup, and that’s when Tracy’s playful shove launched Julie’s squirming ass off her face. And considering the copious quantities of cum decorating her face, I figured Tracy had been a lot more interested in tonguing Julie’s clit, then in scarfing up a second helping of cum! Well I was to busy gawking to laugh, but not Julie! But a couple of vicious whacks with a pillow put a quick end to that! And then, when the girls decided they needed to freshen up, I split for the kitchen.

Reminding myself that the night was young, I popped the top on a cold brew, and contemplated the possibilities! And then, figuring I’d given them enough time, I started back. But when I heard the shower running, I stopped, but decided to peek around the doorjamb, just in case. And my heart just fucking stopped! My sex crazed sister was lying there, naked; knees bent and splayed wide open! Yeah well, she was also pumping a big, thick, neon blue dildo in and out of her pussy with one hand, while she fingered a clit that even from the door I could see was all puffed out! I couldn’t tell how long it was; but, there sure was an awful lot of it sliding in and out of my sister!

Tracy saw me, and called out “Hi Robby, pretty fucking wild night, huh?” But she didn’t stop, and I was beginning to think my sweet little sister really got off on having a live audience! Anyway, she giggled, and slowly slid what I figured was maybe ten inches of dripping wet dildo out of her pussy. Stupefied, I stared while she popped its big, blue, wetly glistening head in and out past the dark rosy pink of her pussy’s lips. And then blowing what little was left of my mind, she watched me watch her treat that blue dildo like a freaking ice-cream cone! Tracy stopped lapping up her own pussy’s juices long enough to ask “hey, you could return the favor you know, or don’t you go down on girls?” Well yeah, I did! Only, never on one shaved as absolutely bare as my sister’s was! And with my exhibitionist sister’s so invitingly exposed, well, the prospect was practically, OK, it was utterly irresistible! And when the nasty minded little tease lifted her legs, spread them wide, and used her fingers to spread herself open, well fuck, I damn near dove head first in to glistening pink!

Kneeling between my sister’s legs, I couldn’t help thinking I was about to do something I’d fantasized about doing, oh say, ever since about the first time I’d jerked off! The shower shut off, Tracy pushed her blue dildo under her pillow, and in a voice that was a breathy whisper, she ordered “Now Robby!” I slid on to my stomach, and slid my hands up along her long tan thighs, gently pushing them even wider. But even before my lips melted in to the soft smooth heat of her pussy, Tracy was chanting “Oh God, oh God, oh God!” And right then, all I wanted was to slide my face all over that hot, slippery smooth wetness! But Tracy pushed her hands in to my hair, breathily insisting “God yes, do it Robby, use your tongue!” So with my sister tugging on my hair, I slid my tongue in to her opening! And what a fucking turn-on, because pushing in to her was like sliding my tongue in to liquid fire! Ramming my tongue in and out, I swirled it around just as far up in to her as I could jam it! Yeah, and I loved the taste of her, and that she was so much wetter then any of the other girls I’d gone down on! Well Ok, and I would have had my tongue reaching for her clit, even if my impatient sister hadn’t yanked my hair, sounding like she meant it , when she ordered “Bastard, stop teasing, and make me cum!”

It was right there, and unmistakable even without Tracy’s gasped “Yes, there, there!” Still, I forced myself to slow it down! So, while I explored her clit, teasing and experimenting, I watched and listened to her reactions. Oh sure, but fast, and fast right on her clit too, was what her tugging hands and a gasped “yes, like that, yes,” demanded! So, I went for it, furiously whipping my tongue over my sister’s silky smooth nub. Well that had her chanting “Oh, oh, oh, oh yes, more, more!” Only that hair pulling was beginning to bug me! Yeah, and the way Tracy had her hips bouncing made it hard to keep my tongue on target too! So, I stopped licking clit long enough to bat her hands away, wrap my arms around her thighs, and pin her bouncing ass down! And that’s when I noticed Julie was back, and sitting on the edge of the bed.

Ignoring Julie, and with my sister wrapped up tight, I began racing the tip of my tongue in fast figure eights around her clit. Well that had Tracy trying hard to buck, and screaming her fool head off, as she loudly and repeatedly demanded “More, don’t stop!” Right, as if I was about to stop, and for sure not once I heard “More, more, that’s it…fuck yes, I’m cuming!” But hey, I waited until her screams faded in to panted gasps. And then, I started sucking her clit! Gosh, and off she went again, but this time with Julie clapping and whooping. And, what can I say? Even while I tongued my sister through what sure seemed like one continuous, unending orgasm, I was thinking about her noisy girlfriend. Well Ok, so it was more like I just hoped she wanted her own ride on my tongue!

I was still caught up in the thrill of making my sister cum, when Julie interrupted. Beating on Tracy’s stomach like it was a bongo drum, Julie complained “Enough you greedy piggy! Yeah, if you know what’s good for you, you’ll share!” Well, besides my serious need to piss, that was just about the only other thing that could have pried my tongue off my sister’s pussy! So I was hurrying back, anxiously anticipating that second helping of pussy, and I walked straight in to one of those dumb déjà vu moments! At least it sure sounded like a rehash of earlier, when I’d overheard Tracy trying to cajole Julie in to going down on her. Only, whatever Tracy was trying to talk Julie in to it sure didn’t involve pussy. Nope, she was trying to encourage Julie to “Just go for it,” insisting “yeah, you’ll love it, fuck, I sure do!” And always helpful, she offered “Come on, I know Robby will do it if you ask him, shit, I’ll ask him if you’re chicken!”

Having heard enough, I walked in. Poor Julie, turning scarlet, she buried her face in a pillow! But hey, she was giggling! And of course my sister wasn’t about to let up, oh hell no! She turned to me, and asked straight out “Hey Robby, you like doing anal don’t you? That giggling chicken-shit over there wants to try it, but she’s too shy to ask! So what do you say, huh? Want to take her virginity?” Well yeah, you bet I did! But then, I sure wasn’t about to confess that I’d be giving up mine too! So I stood there dry mouthed, hoping my nod, and an instantaneous hard-on, made it a unanimous yes!

Whooping like a loon, Tracy sprang up, and began rummaging around in a dresser drawer, coming up with what sure looked like a bottle of lube. Tossing me the bottle, and jumping Julie, she tried to wrestle the pillow out of her hands. Well that left my sister straddling her girlfriend, with her killer ass wagging suggestively. And what do you know, winking at me from right there above my sister’s pussy, was the dusky pink of her own puckered little anal opening. And let’s just say the thought of sliding my cock in to that so sweetly exposed asshole took its sweet time crossing my mind! And never mind all my kid fantasies!! Honestly, up until earlier that night, when I’d watched Tracy not only swallow my cock, but a big mouthful of cum too, I’d never believed anything sexual would go down between my sister and me! But then, guess who was thinking, and yeah hoping, that if a little oral was cool, well then, why not a little anal action too? Well that’s what I was telling myself anyway, when she sent that pillow flying, and dove in to a whispered huddle with a giggling Julie.
