Are you willing to suck your sister's cock?
Dinner and a Show
Nodding your head in confirmation while grinning at her, both of you share a chuckle as you both already knew that you would do it.
After you were done laughing you watch as your sister's face changed before your eyes. She stared at you with a grin that was slowly turning seductive and you noticed a look in her eye that had you feeling incredibly warm.
"Now big brother", she suddenly spoke knocking you into reality again. You then noticed her eyes grew more intense making you gulp before seeing both her hands raise up to that tight restricting shirt on her chest. Elsie trailed her hands over her well endowed chest, slowly cupping them over her breasts before giving them a small squeeze. Your arousal spiked even higher than you thought possible after hearing a small moan escape her lips.
Seeing your face stare at her in a transfixed state, Elsie giggled before saying, "I thought you might enjoy a this. Your getting really hard big bro."
Elsie let out another moan as she fondled her breasts harder through her shirt, encouraged by your apparent arousal. She then slowly trailed both hands down the underside of her breast. You cannot take your eyes off as they slowly widen as her hands travel down to the hem of Elsie's shirt before finally having the will to look in her eyes. Receiving a wink in return you feel your cock throb intensely at seeing Elsie rip the shirt over her head, causing her full perky DD breasts to bounce from following her shirts movement before settling.
You then watch as Elsie exhaled in relief before looking at you with a cheeky grin. As soon as she looked down however, her eyes widen and her grin dropped to slight panic causing you confusion until her left hand reaches out with unreal speed and grasps your right.
Startled you asked, "Elsie! What are...you....", before seeing that your right hand was on your aching cock ready to explode. After figuring out that Elsie stopped you from firing early, you blushed in embarrassment. Feeling a hand caress your face you find your eyes staring into Elsie's seeing amusement, understanding, and adoration with a hint of...pride. You remove your hand form your dick, only to gasp as she replaced it with her own, you look at her questioningly.
Elsie's eyebrow was raised and with a playful grin responded, "I don't want you to fire early Jess. Or at least", before pressing her body into you and softly stroking your shaft, "not before I taste it."
Letting go Elsie takes both your hands and leans back on the bed, pulling you with her and smiling the whole way. With you on top and her bottom you're surprised at her initiative before chuckling catching her attention.
Answering her unasked question you ask, "Seems so far you've been doing all the leading sis, should I expect you wanting to tie me up and wear leather in the future?"
You watch as a heavy blush sprouts on her face before spouting denials and how she wants nothing to do with that, with you laughing at her expense. When both of you calmed down you got into the 69 position. You face her intimidating 10 inch cock and was reminded how large it really was especially up close. The musk coming off of her cock was powerful, in a way that caused your instincts to tell you what a true alpha cock this was. Gulping in trepidation you notice how soft and feminine her cock looked despite it being twice your size when erect.
Hearing a faint giggle you hear Elsie state, "You know Jess, I just can't get over how much smaller you are compared to Fiona and Mom. It's nothing against you of course, I'm just not used to it. But, compared to them yours looks kind of.....cute." Feeling yourself flush you retort, "Yeah, well what about you huh? This thing puts some professional porn stars to shame! Damn Elsie, you all are so big.... and thick too!!" This was proven as you reached out and found that your hand couldn't even wrap around her girth. Softly stroking her shaft you heard her moan, "Ugh....it's nothing....ahh...special at all."
Responding by placing both hands on her shaft before placing your head above the knob you mutter, "Nonsense." before opening your mouth and letting a slim stream of saliva exit your mouth and land on her crown. Elsie feeling the cool saliva landing on her hot head caused her to cry out from the sensation of the two clashing temperatures and the wetness of the Jesse's saliva. She then started to feel Jesse's right hand stroking her underside and the left rubbing over her damp, sensitive cockhead. Regaining her composure somewhat she realized she should start with Jesse's softening cock and placed both hands on his shaft and giving him a hand job, before replying in a slightly confused voice, "What do....oh wow....you...mmmmnnnnn.... mean?"
You just grin and let out an exhale as your sister had started on your neglected cock. "You, mom, and Fiona all have these blessed gifts that most would kill for. Guys would do anything for cocks as large as you three and girls would literally kill to have any of your figures.", you state earnestly before stopping your ministrations and turning your head slightly to Elsie and said seriously, "You all are a bunch of total babes and if any guy can't see how lucky they'd be with a sweet, adorable, game-loving person you are, then they weren't worth it in the first place." You turned back immediately after that, missing the large blush on Elsie's face, and said, " And I will show you not to be ashamed at what you have."
You raise your head over her cock and open your mouth. Taking a deep breathe to shake off your final nerves you take the plunge and filled your mouth with her blushing pink cockhead.
Elsie in response, could not hold back a long moan, before letting out small sounds of "ugh" with each flick of your tongue on the head of her cock. She could only endure your hot, wet mouth as your tongue swirled around as if you're getting a good taste. Feeling a sense a pleasure she never felt even when her mother gave her blowjobs, she was not prepared for the dedication and love Jesse had in store for her. Case in point, when Jesse came up for air after slurping and slobbering on the head of her cock for a few minutes ,before he took the plunge back down stretching his mouth to swallow 7 inches of her cock.
At this point Elsie swore she saw stars exploding before moaning, "Aaaaahhhh Jesse.....ah ah.....oh god Jesse.....you.....ugh.....damn...I....ah mmmmmnnnnnn." Feeling her flushing and thrashing underneath you, you feel a sense of accomplishment of taking this much of your sweet sister. Continuing to slurp on the 7 inches of cock and stroking the rest, you feel pre-cum leak on your tongue. It had a musky, metallic taste with a hint of sweetness. While you may not care for the overall taste it was Elsie's which allowed you to swallow the concoction without a second thought. It proved to be the right thing to do as pre-cum filled your mouth immediately after, forcing you to swallow before it spills out of your mouth.
Your sibling regains her composure somewhat and turns her attention to her big brother's still hard 6 inch cock aimed at outside her mouth . She then smirked while placing both hands on his hips steadying him while thinking, "If you want to play like that big brother I'm game," Shooting her head forward, wrapping her mouth around his cock, she swallowed to the base easily. She felt victory on hearing and feeling her beloved brother moan onto her own shaft. Eyes narrowed in focus she adjusted her arms to wrap from over his thighs, down his lower back, before gripping his firm ass and used her strength to pull him in and out her mouth. Finishing her thought, _"and I'm not losing!!" Swirling her silk tongue around his head three times, she then swallowed him back down, before sucking him hard as she slowly pulled him out before slurping on his head for a moment and then slamming him down.
You on the other hand are caught off guard as you felt everything that she's doing to your cock is steadily climbing to it's peak. You know internally that Elsie just made this another competition to see who cums first. Determined not to finish first you match your sister's more experienced and unexpected onslaught by employing other tactics.
Your left hand strokes the 3 inches left on the shaft while your right reaches out to her heavy balls. Steadily moving your head up and down her pre-cum and spit soaked shaft, your right hand fondles her balls. This has the added benefit of having your knuckles brush gently against her clitoris causing Elsie's body to shake and her to moan on your shaft. Feeling both of your hearts beat faster by feeling how hard your cocks throbbed was amazing. Elsie's response however, once again catches you by surprise.
You feel her take your cock out of her mouth, causing you to shiver in feeling cool air on your drenched cock in contrast to her hot mouth. Continuing to work on both your sister's dick and balls, you grew slightly confused as she took her right hand off your ass and heard a slight,short slurping noise. Hearing a pop your eyes narrowed in confusion, before her hand had returned to your ass and not in the way you expected.
"OK what is she doing back therrrrreeeee!!!!", you screamed internally as you felt your sister shove three wet digits in your asshole, before spreading her fingers inside you probing for something. Knowing what she is looking for you internally thought, "oh shit", as you realize that Elsie will win if she finds your prostate. Panicking a bit you know the only way to even the odds is to deepthroat her whole cock. Cementing your decision you breathe through your nostrils before lifting your mouth to her head while gathering saliva. Chanting a quick prayer you drop down to 7 inches again, but this time slowly inch the head past your throat. Gagging a bit you muster up the will to continue to push. Her cockhead then slips down your throat causing each of your eyes to bulge. In determination you saw her cock up and down your throat while ravishing her orbs in both hands by pulling and rubbing the sweat soaked sack heavily.
Elsie realized her brothers plan and immediately placed his dick back in her throat while thinking ,_"MMMMMnnnnnnn that's clever bro ,but it's too late I'll win for sure!!!" Focusing as much as she can away from the feel of his wet and constricting throat, she search and probed faster until.. MMMMNNNN!!!! "Bingo." Sawing her fingers over the bud she found while moving her head up and down his cock furiously, she felt her own orgasm coming fast. With her clitoris, balls, and cock all being stimulated it's no wonder she's reaching her peak faster than normal.
You in turn could feel your cock is at it's end, but you were proud that you were able to even last this long, not to mention to **** Elsie to try a different tactic.
Both of you are at the end of your rope. Moaning and groaning in absolute pleasure as you sought to get off the other before yourself. Both sets of eyes were squeezed shut and with much determination they continued until at last, the one who broke and sets off a loud groan signaling their orgasm is..............
Who cums first?
