This is the end of this story however I may write a sequel. It seems that some people have to be reminded that this is fantasy, it's meant to entertain that means that it is going to be easy whereas in reality it wouldn't be.

Robert sat on the couch, too stunned to move until he heard a sound from the stairs and realized that his sister would soon reach a position that would allow her to see him in a state of undress. Moving quickly Robert swiftly put his cock away and zipped up his pants just as she came into sight. Erin smiled at him as she passed on her way to the kitchen. Robert continued to sit as he ran over the past two weeks in his mind. He had been seeing a therapist in order to deal with depression and shyness that was making life difficult. The therapist, Miss Pierce, had informed him that his treatment had reached an impasse and the only option was either hypnosis or to refer him to another therapist. Robert desperate for answers elected to go with hypnosis.
Miss Pierce also saw his mother, Linda and his sister, Erin in order to gather more information to help in his treatment. After his mother and sister saw Miss Pierce they had begun to change, while before they both dressed modestly they were now wearing dresses that came to barely below the knee and a neckline that just stopped short of showing anything. Then just today his sister had given him a handjob and his mother had just given him a blowjob after showing her breasts. Robert's reverie was broken as his mother called him for dinner. When he sat at the table he tried to focus on eating as he did not wish to betray to his mother and sister what the other had done for him. However both seemed unaffected by recent events. Whenever he did look up it was usually to find one of them smiling at him, although usually when the other couldn't see her. Robert soon finished eating and rose to return to his room, he had homework to do and he wanted time alone to think about the strange turn his life had taken.
Robert was woken from a sound sleep and realized that someone's mouth was on his cock and sucking with enthusiasm. He opened his eyes to see that it was Erin and she was laying down next to him. Despite her enthusiasm she seemed to be displaying enjoyment rather than any hurry to finish. Robert looked to his right and saw that she wasn't wearing panties under her nightgown and even in the dim light he could see that she was wet. She was so focused on his cock that she didn't notice he had awoken until he began stroking slowly along her pussy lips. However she moaned without slowing her pace and even spread her legs to give him better access. Robert felt her wetness and the burning heat as he began rubbing with greater speed. Erin's moaning grew louder, which felt amazing around his cock, so much so the only reason he didn't cum right away was because of how hard he had cum twice earlier in the day. Robert was prepared to keep rubbing until she came, but had a different idea.
"Erin, could you shift yourself on top of me, I want to make you feel good too?" Again she didn't stop sucking him even as she shifted on to him. Robert pulled her pussy to his open mouth, Erin's reaction was to suck him deeper in shock and she made choking sounds. She quickly recovered and returned to sucking his cock as she had been before. Robert clamped his lips onto her pussy mound sucking her lips and delving between them with his tongue.
Robert concentrated on keeping his teeth from touching her and continued to enjoy the flavor of her. Robert found he enjoyed the sweetness he found between her legs and reached up to squeeze the cheeks of her ass. Erin's moans continued to grow in volume despite the muffling of his cock. Robert felt the cum rising up his shaft and the tingling of the head before his cum flooded Erin's mouth. Again she choked as only some of his cum went down her throat, while most of it either exploded on to her face or oozed on to his crotch. Erin collapsed on to him and Robert struggled to keep licking her slit, both in and around it. Suddenly she stiffened and he felt more juices flood his face and the flavor changed somewhat. Robert's head dropped slightly to the bed and he soon fell asleep.
Robert woke again this time to find that the sun was up and the clock said it was after ten. Robert began to gather himself to rise when there was a knock on the door.
"Robert honey are you awake?"
"Yes, mom." She entered and despite the events of the previous day he was glad that his sister had fixed his boxers as well as the blanket. She sat on the bed smiling sweetly almost coyly. Without warning she threw off the blanket still smiling. Robert felt himself growing hard as she reached for him.
"Honey you seem to be having problems and I want to help." Robert instinctively lifted his hips and she pulled his boxers off. He was now completely erect as she lowered her mouth to his cock. However she was not on him for long before she pulled off and stood. Robert looked over to see why she had stopped and found that she was undressing. It was not a sexy striptease, but rather the action of a woman who wanted her clothes out of the way.
As soon as she was naked she climbed back on the bed, however instead of returning to the blowjob she lay down next to him with her legs spread. He sat up and moved between her legs. Robert leaned forward to grasp his mother's breasts and she moaned softly. He lowered his head to one breast and slowly licked it before taking it in his mouth.
As he sucked on his mother's tit, the strangeness of the situation was not lost on Robert as he was sucking on a nipple that at one time had provided milk for him as an infant. Robert continued to suck until his mother signaled for him to move on to the other side, which he quickly complied with. Robert would probably have moved from one to the other, but there was something else he wanted to try. He had tasted his sister and now he wanted to taste his mother. Robert shifted position so that he could lower his mouth to her pussy and eagerly taste her. The taste was stronger than his sister's but he still enjoyed her flavor. His mother moaned loudly as he clumsily tongued her.
"Oh, Robert no one has ever done that before." If she said anything else he couldn't make it out through her moaning and her tightening thighs. Suddenly the flavor changed and her thighs tightened further as both hands clutched his head. Robert quickly stopped trying to swallow her juices and merely concentrated on breathing as she practically crushed his head in the throes of orgasm. Robert collapsed as his mother released him and she lay back breathing heavily. Robert's face was coated in her juices and he slowly raised himself to his knees. He was just considering retrieving a tissue to wipe his face when his mother opened her eyes, her breathing returned to normal.
"Robert that was incredible is there a girl I don't know about who has been teaching you?" She smiled but it seemed that she was serious about the question. Robert hesitated before answering as he considered the tone she had asked the question in. Robert was certain he was imagining things, because it sounded like she was asking if there was someone she should be jealous of.
"No, mom there is no girl there never has been. I'm a ...virgin." He gasped out this last bit in shock that he would say this to her, but then again after going down on a woman, you are past the point of such embarrassments.
"I know we shouldn't, we have already gone too far, but somehow I don't care. Robert I want to be your first honey. Please make love to me." Robert could only nod as he slowly moved into position and lined his hard, throbbing cock with her pussy. She stiffened slightly, but quickly relaxed as he moved slowly to penetrate her. Robert moved with agonizing slowness, because he had heard that this could be painful for the woman if one is not careful. Once he was fully inserted he lay down on top of her feeling her breasts against his chest as he began moving in and out of her. She embraced him as he began increasing his speed and she moaned and breathed harder into his ear.
Robert couldn't believe the strange turn his life had taken, after years of fantasizing he was losing his virginity to his mother. Robert continued to thrust with vigor, but knew that her pussy was too tight, too amazing and he would never last. He only hoped that he wouldn't cum before she did. Robert had heard of girls complaining because their boyfriends came too soon and they had to get themselves off while the boyfriend slept. Robert began trying to think about anything to hold off his impending orgasm and began kissing his mother's neck in the hopes that this would help her cum before him. Her pussy only seemed to get wetter and he found it somewhat easier to thrust into her.
