Should you use your little sister's gift so soon? Should you use it at all?
A Bit of Fun
She was a slime, you were a human. Her race probably had a whole different way of copulating, lewd stuff to her was probably more a curiosity than a real sexual urge. It’s not like she was actually here, not really. And she did give you the most amazing gift imaginable on the hopes you’d be “naughty” with it.
These are the things you tell yourself as you put down your phone and pick up the hammer. You hadn’t decided quite how to use it yet but you thought Trixie deserved a little something extra for such a once in a lifetime gift. A bit of fun just between you and her. But first you had to figure out how to reshape it
You turn the hammer over to look at it from every side. It was just a hammer, or a replica of a hammer though in impressive detail. Tapping it against your palm you feel it had heft to it and the solidity of a dense rubber. Placing a hand on each end you squeeze together but the stiffened jelly holds firm. You try to bend it, twist it, and squash it flat but the shape remains strong. You think back to the first time you’d molded it. It had shaped so easily that time. Was it stuck? Had something in the magic screwed up?
“Ah!” You snap your fingers. “Magic. Keep an open mind Jacob.”
Now you remember how you did it. You clear your mind and allow yourself to enter a free flowing mindset of imagination and creativity while also projecting an appreciation that this toy was no mere inanimate object but a living piece of your sister. You once more push the hammer in from top and bottom, this time the jelly shapes easily to your touch. Soon you have it back into its original egg like shape.
“Ha ha.” You grin a wicked little grin. “Now, what to do?”
You already knew you wanted to tease your sister without going too far. She might be ready and willing but you weren’t cool with crossing too many boundaries with her…just yet. You shake your head to clear it of improper thoughts. No, you’d never cross those boundaries. Not with her or any family member!
“Hmmm.” Your evil smile widens as a wonderfully terrible idea strikes you. It was certainly naughty, like she wanted, but probably not what she had in mind.
Holding back a laugh you place the toy on your chest then start to stroke yourself. Normally you’d get some pictures or videos going but today you were so fucking horny those wouldn’t be necessary. You lie back and let your own imagination run free as you slowly and gently dry rub your rapidly swelling cock.
The vision that springs instantly to your mind shakes you as much as it excites you. You think…of your twin. Your first instinct is to shut these thoughts down at once, but something keeps you stroking. She was an amalgam of contradictions that fascinated you on far more than an intellectual level. That face, you didn’t think one so alien could be so achingly beautiful. How it glowed, how it felt so soft to the touch, six glimmering black eyes with fathomless starry depths within. That skin of hers, strangely frictionless yet capable of an unyielding grip. The more you thought about it the more you craved to feel it again. That power of hers, mysterious and irresistible yet she had a soul that was **** and pure. Though impossible to see directly her shapely torso, at the scale of an 7 foot plus amazon woman, was sexy as hell. You knew she had the abs of a goddess, you knew she had firm perfect breasts from that moment you had touched one, her hips and ass round and voluptuous. Yet the allure ran deeper still. Darkness. Tentacles. Wrapping, writhing, snaking around your feeble mortal body.
You didn’t know why this was turning you on but it absolutely was. You open your eyes to see your cock rock hard and standing tall.
You couldn’t feel guilt, mentally yes but not truly deep down in your gut. She was your twin yet also a woman you’d just met as an adult for the first time yesterday. You didn’t have the lifetime of memories you’d normally have with a family member. There would time for guilt later but right now you just allow yourself to go with the flow, it’s not like you’d ever actually act on this inappropriate yet ultimately harmless secret attraction. Thankfully she couldn’t spy into your perverted mind.
“Oh!” You remember what you were doing here. Letting go of your manhood you return to the Trixie’s gift. The idea you had sprung from her own words. Make an eye, she said, and she could see out of it. Well, you were going to give her an eyeful today.
You shape the thing into a large ball then trace a pupil, an iris, and even eye lids over the spherical shape. Just as with the hammer once the form was close enough…POP! Suddenly you have a large jelly eyeball in your hand blinking and looking around the room. You smile and give your sister a wave. In the dim light you weren’t sure how much she could see but you knew it would be enough to drive her crazy.
It takes all you had not to start laughing and your rational mind is telling you to stop now, but your rash penis brain had you fully under it’s influence.
Taking the eye from behind you pan it around to give the room a quick sweep, making sure that your erect dick is plainly visible for a good couple seconds before swinging back to your face. You give her a cheeky wink.
With your free hand you grip your shaft and start stroking once more. The lewd, if brief, bit of exhibitionism stoking your already hot fires. About ten seconds pass before your phone chirps to an incoming text message. You stifle a laugh as you already knew who it was. Balancing the eye on your chest, pointed toward your face, you check your screen. Obviously it was Trixie.
“OMG! Yes!” This short message is followed by a slew of heart eyes and drooly faced emojis. “MORE!”
You knew you shouldn’t, you really knew you shouldn’t. Propping the phone so you could watch the screen you start fapping once more. Again you give her a little glimpse of your goods, this time a bit longer and you don’t stop the action. You hold it as long as your nerves could handle before swinging it back to your face as you blush furiously. This is so BAD!
Another onslaught of emojis fill your screen making crystal clear that she liked what she saw before she ends it with. “Jake! I didn’t know big brother was so BIG!”
Your blush deepens and you let out a little chuckle. At 7 and a half meaty inches you certainly had nothing to be ashamed of downstairs, but being called big always felt good for a guy. And having yet another thing for your little sister to be impressed by you about was forbidden icing on the taboo cake.
Another message comes. “I’m in math class! How am I supposed to concentrate now?”
You loved imagining your sister sitting there as the teacher droned on yet also watching a home porn movie, of her brother no less, with nobody the wiser. How would she react if you… No, that’s too much. This was so terribly reckless already. You knew you’d live to regret this moment and yet you don’t stop.
More messages stream in. “Show me more!” A moment later. “NO! Make a mouth, let me taste it. I’ll suck you so hard.” Another moment later. “NO! A pussy! Let me feel your big fat cock in my tight little pussy! Fuck me Jake, fuck me!”
You had her burning up! Ha! Sitting there stuck in class as you lay here masturbating for her entertainment. You wished you could watch her there squirming and blushing like you knew she was. You make a kiss toward the eye before slowly, agonizingly slowly, you turn it around…then pan really quickly over your schlong.
“TEASE!” Comes the text. “Jake PLLLLLLLEEEAASSSEEE!!!!!!!!!!!!!!!!!!!!!!”
You keep this going for a time. Quick glimpses, teasing glances, close ups too close to make out detail, and arm’s length views showing as much of your body as you could but leaving the good stuff just out of sight. All the while a steady stream of texts spring up over and over on your phone’s screen.
“OMG!” “Holy fuck I’m so horny!” “Oh God you look so fucking sexy!” “More! Show me more!” “I love your big beautiful cock!” and everything else a sister ought not to say to her big brother. She begs, BEGS, for you to make a pussy out of her gift to fuck. You are sorely tempted but you hold the line. “Fuck me! Fuck me! FUCK ME!”
This was so fucking FUN! Nasty, forbidden, twisted FUN! Performing for your sister, as you also secretly dreamed of your twin, was better than most of the actual sex you’d ever had. Before too long the end is swiftly approaching.
You are fapping fast with an orgasm bearing down. You hold out as long as you can, mouthing clearly and distinctly toward the eye “I’m gonna cum!”. Your phone blows up with messages but you ignore them. You hadn’t planned on still playing with the eye at this point, thinking fast you decide to tuck the eye under a pillow but you grip too hard and the sphere, slick from your sweaty grip, slips from your hand to land on your body. It rolls a moment before coming to rest on your tight tummy staring straight up at your locked and loaded flexing dick. Beatrix got the full view this time, not on purpose but the wide staring eye lands just perfectly to see your thick veiny penis let loose in exquisite up close detail.
“FUCK!” You grunt as your climax hits you like a ton of bricks. The first thick rope of jizz blasts across the eye and streaks down your flexing stomach, followed by another and another and another. “JEEEEZ!” You are powerless as you buck and moan loudly and milk your throbbing cock through a mother fucking A-bomb of a nut with your cute little sister watching on as if she were right here. “OHHHHH FUUUUCK!”
“FACIAL! OMG I love it! Yes! Give it to me!” Your sister’s excited text comes through instantly, she had no clue this wasn’t a part of what you’d planned. “YESSSS!!!!!! Give me your cum baby! Yeah, all over me! YOU ARE THE BEST!!!!!!!!!!!”
“MMMMRRRRRMMMM!” You growl as you empty your hard pumping wad to an adoring audience of one. The instant, the very fucking instant, it is over you are flooded with guilt and regret. Boner brain gone your sober mind gains control once more. You let go of your dick as if it were hot lava and scoop up the eye to turn it away.
Jesus Christ, what had you done? God damn it! Not Trixie. You didn’t mean to get that nasty with her. You thought you’d tease her, give her a few glimpses, then finish on your own. After such an amazing gift you thought a little treat would make her happy. Instead she got the full Monty, money shot and all.
You feel like absolute dog shit as you watch the shameful texts and emojis continue to stream in. “Make a mouth, let me suck it up.” “I wanna taste you Jake!” “God I’m so horny for you!” Worst of all… “Look how wet I am for you.” Which included a blurry shot of what you assumed were her pink panties under her skirt as she sat in class. She had loved it! She might be all grown up now but you were her big brother. Her protector. Her guide. You knew better than this.
Reaching down you grab the eye, smearing your fingers with your still warm oozing cum, and reshape it back into its base form. You try to ignore the texts as you clean yourself and the gift up with the tissues as the texts keep coming. Most of them say things you never wished to hear from your sweetheart baby sister, the others were expressions of love and admiration. “I love you Jake! Thank youuuuuu! You’re the best big brother EVER!!!”
Eventually, hesitantly, you reach down and simply reply. “I’m so sorry.”
Melting back into the bed you felt lower than a snake belly. Disgusting, revolting, just plain icky. But holy fuck…what an orgasm!
