In the last two letters I told you about how Robert was seduced by his sister, while Johnathan was seduced by his manipulative Aunt. In this letter, I will explain to you what happens when Johnathan comes to visit his brother and sister at their apartment.
______________________
Robert had been having sexual relations with his sister Angela for eight months now, throughout both the first and second semesters of their respective college programs. Living together in an apartment paid for by their parents there was no restraints placed upon the rate at which their relationship could grow. And it had grown in leaps and bounds. Angela had early expressed her submissive nature to Robert, asking his to take control of their sexual positions and to demand sex from her as the impulse struck him. Once offered the opportunity to fully control his sister's body and to use her as he pleased, Robert soon recognized within himself the naturally dominant character to his own personality.
Initially Angela had been the more sexually experienced of the two, having had a boyfriend before her relationship with Robert. But in introducing her brother to sex and assisting him in refining his techniques, soon thereafter Robert took up the reigns and dominated his meek minded sister, who instinctively accepted the role of submission and obedience. Robert quickly established the routine that they would live by for the remainder of their school year. Keeping his own bed in his separate bedroom to maintain appearances, each morning Angela would enter his room completely naked. Standing before him with her slender tall frame Robert would look up from his bed at her soft white flesh, her perky apple sized boobs, her muscular long legs, the flatness of her smooth belly and her cleanly shaven pussy lips. Pulling back the covers to reveal his own naked body and erect penis his sister would assume her position between his legs. Flipping her long straight dirty blonde hair behind her neck Angela would lean forward and begin the process of giving her brother his morning blow-job.
A young man wakes up with a hard-on pretty much every morning. That cock needs to cum every morning. Most young men just jerk themselves off each morning, in bed or in the shower. Robert had done so for many years. But he decided that he deserved better. He decided that he deserved to have his cock sucked every morning. And he decided that when he came, it should be into the gaping mouth of a sexy horny woman. Johnathan decided that his sister would be the one to suck him off and swallow his load each morning. Angela had sucked cock before and was familiar with the process, but now with the continuous daily practise that she was receiving her own technique improved substantially. She loved her brother, she loved his cock, and she loved pleasing him. She enjoyed the daily routine and often woke up before the allotted time and began rubbing herself, anticipating when she would have his cock to please with her mouth.
At first she would focus on the head of his stiffy. Licking, caressing with her lips, kissing, gently sucking, taking pleasure from his pleasure. Working her way down the shaft she would slowly devour each inch by inch with her tongue and lips, occasionally interrupting her progress by returning to suck on the head of his cock. On reaching the base of his long beautiful dick she would begin to pamper his balls, lathering them with broad long licks. Her brother had a big set of heavy balls and she loved to please them as much as she enjoyed pleasuring his cock. Taking each testicle into her mouth she would gently suck on the treasure.
Having warmed up his cock as well as her own appetite she would then return to the head, and placing it her mouth, she began the process of feeding the full length of his cock, inch by inch, into her hungry mouth, descending a little further with each deep gulp, then raising her head upward and descending down a bit further again. Eventually she would have his entire cock engulfed within her heavily salivating mouth, the head pressing hard against the back of her throat.
At first she could not take his full length, but Robert insisted on personally training his sister to perform as he desired. And so for many weeks every night she would sit before him on the floor while he sat on the couch watching TV and Robert would have his sister practise the art of feeding his whole cock into her mouth. When she felt like gagging or found it hard to breath and would begin to panic Robert would seize her head by her long hair and force her head to stay in position, and then even force her face down over his cock a little more.
"Look up at me my slutty little cock sucker." Robert would command, and Angela obeyed. With their eyes locked and her head pinned on his cock Robert would watch the fear in her eyes gradually recede as she began adjusted to the feeling of the hard cock deep in her throat. Holding her firm she got used to not resisting, and ultimately to trusting her brothers judgement. When her eyes began to roll back in her head from not being able to breath Robert would relieve his clamp and release her for a gulp of air. Then she would return to taking the cock into her mouth and feed more and more in, gradually learning day by day to accept more cock into her throat. When again she would choke and panic and try to back off, then Robert would repeat the process grasping her by the hair and binding her tightly, holding her head in position, until she surrendered her resistance and blindly trusted her brother's control.
It took many weeks of hours every day to fully teach his sister how to accept the full length of a cock down her gullet as easy as her pussy accepted his dick, but it was worth the effort and sacrifice. Now, each morning, she performed her job dutifully and wonderfully, and he would watch as she impaled her face with his cock and then fuck her own skull by quickly pumping her head up and down while tightly clamping her lips around his dick, just as he had taught her. From time to time Robert would pin her head down with his fully dick in her mouth, holding her by the hair and admiring her golden locks. She would stare upward toward him and when he saw saliva begin to pour from her mouth down his dick and as he watched the white of her eyes appear, he would release his cruel grasp and without as word or a gag, as he had trained her, Angela would immediately resume fucking her face on his cock.
When ready to cum each morning Robert would pin his sister's head down over his cock and holding her in place would release his semen directly into her throat. Angela had never been a fan of swallowing semen, but this her brother had also demanded of her, and now she eagerly gulped down the mouthfuls of slimy fluid, every morning going to class with a belly full of cum. Leaving her own sexual needs unattended to each morning to ensure that her pussy would be willing and eager for penetration when he was ready to cum again, Robert selected the clothes for his sister to wear to school each day. Where she had always been a shy girl and dressed conservatively in long thick skirts and heavy concealing sweaters, Robert had changed all that. Having her try on new clothes and providing her a new wardrobe, now Angela was required to dress like the slut that she served her brother as.
