A double blowjob.

I stared at my sister. I was aroused so it shouldn’t be surprising that I paid a lot of attention to her naked body. She was short, like 5’2”. She was petite in general but that just made her DD-cups look fucking enormous. I watched her turn to her dresser and present her pert little butt in my direction as she retrieved a pair of panties, jugs swinging enough to be seen past her sides. Then I got to watch her slip the green and white striped t-thong on, her fingers sliding her curves as she adjusted it just right into the crack of her ass.

I was suddenly self-conscious about getting caught checking my own sister’s ass out, but when I looked over at Jane she was playing on her phone again. I was confused. I’d never known Imogene to be this casual about her body with me before. At home, she’d always worn a robe when moving from the shower to her room and there had been at least one occasion when I walked in on her changing and she screeched at me. And yet there she was, calmly picking out a bra with her tits in perfect profile display for me.

My cock was still straining and aching against the seams of my jeans and so my thoughts were still in the gutter. Given their inappropriate topic of conversation I didn’t see too much problem with approaching Jane and brazenly asking her, “Well, I’m sure you won’t mind telling me what size bra you wear, right? Those tits look pretty huge, you know?”

The purple skinned mutant smirked slightly as she took advantage of my position standing over her to ogle my crotch, “Hardly huge. 34-D is like average around here.” She pointed looked at Imogene's larger pair.

Seriously, what was going on? Did Jane just have the hots for me and my sister was down with getting us together? And she was still checking out my package! “Damn. Do you just want me to whip it out?”

Jane nodded like this was a perfectly reasonable idea, “Sure. Go for it, guy.”

Aroused as I was, I really had the urge to just do it. Imogene in the room or not. I looked back over my shoulder. “Hey sis. I’m going to show my dick to your roommate, alright?”

"Yea, Okay..."Imogene replied. Her tone was distracted and uninterested as she stood in front of a mirror, switching back and forth between two dresses held in front of her underwear clad body.

Fuck it. I was calling their bluff and I had this strong feeling I might actually get a piece of this hot mutant ass, so I unsnapped my jeans and shoved them down my thighs. I was a bit self-conscious about the white briefs I was wearing; the underwear sort of infantile but they were the most comfortable. I’d tried boxers but having my junk swinging freely was just inviting chafing. In any event, I reached into the waistband and retrieved my erection before Jane could focus too much on my underwear preference.

I finally got a rise out of her as she pressed backwards against her headboard, her eyebrows hitting the roof. “Shi-it!” she breathily intoned. Then she winced and pressed a hand to her navel, “My pussy’s sore just looking at this thing!”

Imogene half laughed, “I know, right? It’s like a baseball bat of cock-meat!”

Hearing this from my own sister’s mouth had me lifting my hands to partially cradle my head and silently ask the universe, “What?!?!” But my bewilderment faded pretty quickly in the face of just how arousing this situation was. So… “Come on, Jane. How bout touching it, then?”

She smirked but shook her head, “Nah, I’m alright. Here.” Her skin color changed back to purple and I suddenly didn’t feel like taking no for an answer. I grabbed her wrist and pulled her hand into contact with my shaft. I sighed as she gamely took me into her grip, squeezing lightly. “Guess I asked for that going violet, but it's really my most neutral effect.”

Imogene laid down on her bed nearby, now wearing a yellow dress, “Yea and it’s not like he’s going to just stop being horny cause you shut off the pink. Fuck it, I’m still randy.”

I scoffed as I looked at my sister. “You are a freak, sis. I can’t believe you’re just watching this shit!”

Rather than pissed as I expected, my sister’s pretty elfin features just looked thoughtful. “I don’t know. I wouldn’t want a dick like that anywhere near my vagina but it’s dead sexy to look at.”

“And play with,” added Jane as she finished a long stroke with both her hands and then slapped my length thickly into her palm, “It’s a heavy motherfucker-”

Ohmygod I was so horny and feeling decidedly confident, I intoned, “Would you fucking suck it already?”

Jane rolled her eyes, “You’re lucky you have a big dick-mmhp…”

Tell me about it, I thought as Jane preceded to suck my cock like a pro, licking and bobbing, even throwing in some theatrical moans. I was in heaven and my hands naturally gravitated to the top of her bald head, my fingers slipping down to run along the strangely soft flesh of her tenta- her Lekku. The pace of her blowjob immediately changed and I felt a definitely real moan of pleasure translate through her mouth to a buzz around my cock. Encouraged, I gripped them more firmly with both hands and lightly squeezed as I went down their length. Jane’s eyes were rolling back in her head and her face popped off my cock, thick strings of saliva connecting to her wide open moaning mouth.

I shot a bewildered glance Imogene’s way. “Those are like great big clits for her,” she told.

I turned my attention back to Jane and relented my **** on her lekku somewhat and she glomped upon my cockhead like her life depended upon it. She bobbed her head furiously as her tongue eagerly stroked the bottom of it. Her hands worked the shaft in time with her mouth and I was having the time of my life, even if I had no idea what I’d done to deserve this.

My head was thrown back and my face was surely squinched up in ridiculous pleasure face. “God, this is fucking hot,” I heard Imogene say.

Without looking I had the distinct impression that my big sister had a hand between her legs. I have a hot sister and a hot mother too. I wasn’t too good to admit that I’d had sexual fantasies about both of them every once in awhile. As driven insane with lust as I was at the moment it shouldn’t be too much of a surprise that I blurted, “Fuck it. Come over here and suck it too, then sis.”

It assuredly was a surprise when she actually did it.

“Oh Jane!” I called out, “Tha-ank YOU!,” He gripped both of Jane’s lekku on either side of her skull and slowly drove my hips forward, driving the pace of the blowjob as she relented to letting me fuck her face.

Then my eyebrows were hitting the roof as Imogene’s pink haired head pressed between us and she started slathering the side of my shaft with her tongue and lips. Her big blue eyes met my questioning ones and there was a slight shrug of her shoulders as if to say, ‘it’s just a blowjob.’

Sure...just a blowjob...yea…

One of my hands was now resting in Imogene’s tresses and so Jane took the moment to back off my cockhead, spit once again hanging between us in trails, “You two do this a lot?”

A burst of amusement shot through me at that and I cracked sarcastically, “Oh yea. It’s totally normal for my sister to blow me and ...ha... even for her to spread her thighs for me whenever I’m in the mood!”

Imogene’s tone was absurdly enthusiastic as she took full possession of cock from Jane, “Can you fucking blame me?! Look at this bad ass meat stick my brother’s packing! Fucking A,” she declared before popping my glans into her mouth. She sucked it furiously, her cheeks going concave as she gave me this smoky hot look.

Then her hands were tugging my briefs down and she spit out my cockhead to tell Jane, “Here Jane, lick his balls.”

Jane flinched and pushed back against Imogene’s chest. “Eww...they’re hairy and look- really sweaty.”

Imogene rolled her eyes, “Yea? They’re also as big as baseballs and fucking full of fucking cum. Now come on!” She gently took a hold of Jane’s right lekku, instantly drawing a staggered whimper from her throat as she slowly thrust her face forward. Imogene engulfed me right next to Jane’s ear as the purple mutant reluctantly sucked at the loose skin of my scrotum.

“Good God, Imogene,” I pleaded. My sister had the front third inside her mouth. She swirled her tongue as she snaked her neck side to side. She licked against the bottom of me as she retreated off of my cock. Her eyes laughing as her lips opened with a pop.

“Are you going to fuck me with this big fat monster cock?!!” Imogene laughed upwards. Her wrist was pumping hard over Jane’s puffed out cheeks. The purple mutant had apparently gotten over her distaste because she was eagerly assaulting my left nut with her tongue and lips while she cradled and squeezed my right with her hand.

Hearing my sister say that along with Jane’s ministrations on my sack sent me over the edge. “Holy crap, Imogene! I’m- I’m cummming!” I clenched my eyes shut and roared as I came. A hand pumped gently down my length in time with my long drawn out orgasm as my balls unloaded everything they had.

It felt like several minutes but eventually my climax relented and I collapsed in a heap on the side of the bed. I opened my eyes when I heard Jane say with distaste, “Well, thanks for saving me from cum all over my face but uh… what are you going to do with it now?”

Imogene had a smug expression on her face as a fat white orb floated a few inches above her held out palm. She shrugged, “Put them in the toilet eventually. Seems like a waste though…”

What?

“Them?” asked Jane as she slid off the bed, apparently more comfortable sitting at her desk.

“Sperm cells.” replied Imogene a look of concentration crossed her features and a long spike shot out from the orb which shrank. The spike swiftly retracted back into the orb which swelled back up to its original size.

“You don’t think that’s kind of… ick, playing with your brother’s semen? I know you guys probably fuck all the time, but still..” said Jane and I was just realizing my sister was using her power on my jizz when the full implications of the purple girl’s statement hit me. She knows we fuck all the time?! The hell?!

Imogene snorted as the orb of my cum became a streamer wandering the room, “The way my power works, I’m intimately familiar with all the bodily fluids around me, which means this semen already feels like it's mine. So does the blood in both of your bodies and that also includes the sex juices lubing up your vag, girl.”

As Jane expressed her disgust, my sister’s eyes turned to me and a wicked grin curved her lips, “Speaking of which-” She lifted a fist and then pointedly raised one finger while staring at my crotch, “Up and at’em boy.”

I felt my flaccid member swell with blood instantly and completely with no pauses. Within seconds I was completely hard, my cock bloated to its fullest erection.

Imogene asked me, “You're in the mood, right?”
