I recommend that you read chapter 1 and 2 before delving into chapter 3, but here is a quick recap reminder of what happened. Eighteen year old Kevin Lansing came home to find his older sister Hannah licking his twin sister Kristen's hot pussy. He quickly stripped down and joined in on the filthy fun, where plenty of licking, sucking, tonguing and fucking took place. Later, their mother Krystal, a dominant mistress, and father Kevin, a submissive pet, came home and the fun continued. After some punishment was served to Hannah, Krystal devised a blowjob contest between the sisters.
Chapter 3, The Blowjob Contest
The contest was set up. David and Kevin were seated on opposite ends of the sofa. Kristen was kneeling in front of her father, while Hannah was in front of her brother.
"Okay ladies, your goal is to make the cock in front of you cum first. You can use your mouth and hands only to do whatever it takes. The winner gets to enjoy a hot and sensual evening with me, while the loser spends the evening in bondage in the doghouse. The first man to shoot his load will join the loser in the doghouse, the other will join myself and the winner. Any questions?"
Everyone shook their heads. The girls looked at each other, sizing each other up. Kristen was well aware that this was going to be a tough race. Hannah's technique of cock sucking was second to none, but she was working on Kevin, who for some reason had enormous control when he wanted. Plus there was the fact that Kevin had recently cum, and Hannah had just moments ago nearly passed out from intense pleasure, moments after enduring fifty blistering spanks. If there was ever a time for Kristen to beat her sister at blowjobs, this was that time.
"Okay girls, on the count of three. One...two...three."
Both girls lunged for the cocks in front of them. Hannah took her brother's cock in her hands, her right hand sliding under to cup his balls, while her left hand gripped his shaft and began to stroke. She looked lovingly up into his eyes as she expertly worked him.
Meanwhile, Kristen wasted little time sucking her father deep into her mouth. He groaned as he felt the heat of her young mouth, the softness of her full lips, and her insistent tongue fluttering on the sensitive spot just below the helmet shaped head. What Kristen lacked in talent, she made up for in enthusiasm and quickness. Her desire to stay out of the doghouse was never in question.
Kevin was enjoying his older sister's soft hands as she stroked him, and he desperately wanted to cum, but the thought of spending an entire evening chained up in the doghouse was not a fun thought. He had to hold out no matter what she did. As he watched though, she leaned forward until her mouth was over his shaft, then she released a large gob of saliva, which landed on the very tip and ran down to her clutching hand. "Oh shit!" he whispered, then grunted as her hand began sliding up and down his now slick shaft.
David was certainly enjoying his blowjob from his 'little girl', even though he had received hundreds of blowjobs that were immeasurably better. Kristen tried hard, but she had only been giving head for a little more than a year, and she still had a lot to learn. He made a mental note to have Hannah coach her sometime when Krystal wasn't playing mistress, and he could actually talk. Glancing over at his son across the sofa told him all that he needed to know. Kevin was putting up a good internal fight to keep himself from cumming, but he was fighting a losing battle. He watched his eldest daughter's loving hands glide up and down his son's marble hard shaft, and he could see the writing on the wall. Hannah was giving Kevin a world class handjob, and would very soon be rewarded with copious amounts of sperm bursting forth from his swollen balls.
The entire contest lasted less than ten minutes, and during that time, David did get very close to cumming, but only because he began to picture Hannah sitting in front of him doing the things that she was doing to Kevin. She had primarily used her hands to stroke her brother's cock and fondle his balls for nearly the entire time, but after about seven minutes of stroking, his cock began to leak copious amounts of pre-cum, and Hannah changed her tactics.
Removing both hands completely, Hannah leaned forward and blew cool air on the now purple head. Kevin cried out in agonizing pleasure as his member twitched as if it was being shocked. With a sly, sexy grin Hannah dropped down and swallowed his entire seven inches down her throat, until her plump, pink lips pressed tightly against his pubic bone. No one could see her working her tongue on the underside of Kevin's cock, but he could certainly feel it. She would wrap her mouth muscle around his shaft and move it up and down, giving him a stroking effect deep inside her throat. Then, when she needed to take a breath, she sealed her lips around him and lifted up with building suction, her cheeks collapsing in, until just the head remained in her mouth, before plunging back down all the way.
"Ohh fuck Hannah. St-stop, you're gonnna- gonna make me cum!" Kevin blurted, his face a mask of pleasure and strain. He was still fighting it, but she was winning. The slurping sounds coming from her mouth as she worked her magic, served to heighten his senses even more and push him that much closer to the point of no return.
"That feels so good honey, you're gonna make daddy shoot soon," David said, worried that his youngest daughter's feelings would be hurt if she didn't make him cum. After many years in the business, he had the ability to shoot his load pretty much on demand and with very little physical stimulation. Krystal new that he could force himself to cum, and she knew that he wouldn't have as much problem in the doghouse as Kevin would, but he wasn't about to intentionally throw the contest and risk punishment, because he knew that Krystal would know if he did.
"I- I can't hold it," Kevin cried out in fevered passion as his sister slurped her way back to the very top and stopped for just a moment to dig the tip of her tongue into his pee hole, before once more dropping back down to the base, a low victory growl emanating from her chest as Kevin shouted, "Ahhhh fuuuuck I'mmmm cummmmingggg!"
Hannah gripped Kevin's hips tightly and stayed down on him as his orgasm began. She felt his cock swelling even larger in her mouth, straining her jaw even more. The head of his cock was well past her gag reflex, something that she had long ago learned how to suppress, and when the first spurt of hot creamy cum fired out, she felt it coating her throat with a warm slipperiness as it slid right down into her belly.
"Right there, oh yeah, that's it baby, here it comes," David growled as he pushed himself to begin his orgasm. Kristen pulled her mouth off and gripped her father's cock tightly as it began to release its seed. The first spurt oozed out and ran down the shaft, lubricating it. She continued to stroke it, as more and more cum came out, covering her hands. She looked over at her sister and twin brother and felt a twinge of jealousy. The look on Kevin's face was pure bliss, and Hannah still had his cock all the way in her mouth. She wished that she could do the same for her brother, and vowed to herself that she would practice hard until she could do the same.
Kevin felt like he would never stop cumming, and Hannah would never stop sucking and swallowing, but all good things come to an end and this blowjob was one of them. As his orgasm wound down, his beautiful older sister finally released him from her mouth with a smacking sound. She looked up into his eyes and said, "Sorry Kevie, but I didn't want to lose."
