After having sex with his grandmother, his mother, and his sister, taking his time making out with her and feeling her through her clothes, Kris undresses his Aunt Nancy, while his two cousins, Anne and Mary, watch.
Revised, Rewritten, and Continued from Chapter 03:
Then, in the way that he was all over his sister's big tits, she was all over his erect prick. If it wasn't sexually exciting enough that his 21-year-old sister, Gina, allowed her 19-year-old brother, Kris, to not only feel her breasts through her clothes while making out with her but also, she felt his growing erection through his pants. Even though sex between them was expected and consensually agreed upon beforehand, it was still hard for him to wrap his head around him having sex with his big sister. Normally, she was such a bitch to him.
Yet, now that his grandmother and mother already had sex with him, all part of his coming of age process from being a virginal male to being a sexually experienced man, it was his sister's turn to have sex with him. While waiting for her to stop him, surprising him when she didn't, Gina allowed him to unbutton her blouse and remove her big tits from her bra. While he felt her naked breasts, she felt his erect cock through his pants.
Something he thought that his sister would never do, with her not allowing him to have all of the sexual fun, she unzipped his pants, reached her hand inside, and pulled out his stiff prick. He couldn't believe that his big sister was holding his erect, naked prick in her hand. Kris watched his sister fondle the head of his cock with her manicured fingertips. Then, sexually teasing him, she slowly stroked him while staring up at him with her big, blue eyes.
'If it's not enough that my sister allowed me to feel her through her clothes while making out with her, she allowed me to unbutton her blouse, remove her breasts from her bra, and touch them and feel them. Now, another one of my sexual fantasies come true, my sexy, topless sister is holding my naked prick in her hand. I can't believe my sister is holding my naked cock in her warm, soft hand while staring at it, fondling it, and slowly stroking me while sexily looking up at me with her big, blue eyes.'
She fondled the head of his cock with her manicured fingertips while continuing to make out with him. Then, she stared down at his big dick as if she had never seen a big prick before. Obviously, with her sexually aroused as much as he was sexually excited, she stroked him a little faster and a little harder. Ready to give him what he wanted, but before she did, she stared up at him again to give him a sexy look and a naughty smile.
'My sister is such a tease,' he thought.
Already ready, she was hungry for his prick. With her not needing any foreplay to get her in the mood, as if she wanted to blow him as much as he wanted her to blow him, he didn't have to finger her pussy or eat her cunt. His sexy, big sister, did what he thought she'd never do but had always sexually fantasized that she'd do whenever masturbating himself over the imagined thoughts of seeing her naked and having sex with her. Hard to wrap his head around him having sex with his sister, she was ready to blow him.
While continuing to slowly stroke him, she lowered her head and kissed his cock and licked is cock before taking him in her mouth. As if he was her boyfriend and/or her lover, he couldn't believe that his sister had his erect cock in her mouth. He ran his fingers through her long, blonde hair while she continued sucking him. Kris couldn't believe that his sister was blowing him.
In the same sexually excited way that he watched his grandmother and his mother when they took him in their mouths to suck him, he watched his sister, Gina, when she took him in her mouth to suck him. Something he thought that he'd never see, yet, something so very sexually exciting to see, his sister was blowing him. A sexual fantasy come true; he couldn't believe that his sister was blowing him. A sexual memory that he'd never forget and would remember for the rest of his life, his sister was willingly, voluntarily, and consensually sucking him.
'Oh, my God. This is so unbelievable. I don't believe this. After two generations of women in my family, my grandmother and my mother, gave me blowjobs, the third generation of women in my family, my sister, is giving me a blowjob,' he thought.
As if he was dreaming, he watched his sister sucking him. In the way that she was stroking him bobbing her head up and down and side to side, she appeared to be enjoying giving him a blowjob. Then, sexually teasing him, she stared up at him with half of his erect prick in her mouth. Obviously, she wanted him to see her sucking him. Clearly, she wanted him to see her blowing him.
'My sister has my erect prick in her mouth. I can't believe she has my prick in her mouth. She's blowing me. My sexy sister is blowing me. I can't believe she's blowing me,' thought Kris while watching his sister suck his cock. 'She's sucking my cock. I can't believe she's sucking me.'

In the way that his grandmother, Kristina, and his mother, Barbara had sucked his cock and allowed him to cum in their mouths, Kris couldn't believe that his big sister, Gina, was sucking his cock. He wondered if she'd allow him to cum in her mouth, too. Something that he had only imagined her doing while masturbating himself, he never truly believe that his sister would ever blow him. Even though his grandmother and his mother surprised him by giving him unbelievable blowjobs, his sister sucked his cock even better than them.
She sucked his cock the best. With his sister a very talented cocksucker, obviously, she had stroked and sucked many cocks before. Even though he only had two blowjobs to judge her cocksucking skills by, able to compare his sister's cocksucking skills to his mother's and grandmother's cocksucking skills, Gina was the clear winner.
With him so very sexually excited, even more sexually excited than when his grandmother and his mother stroked his cock and sucked his prick, he placed a gentle and loving hand behind his sister's blonde, pretty head. Becoming too sexually excited too fast, as soon as he pressed down on the back of head and filled her mouth with all of his stiff prick, that was it for him. Unable to hold back, surprising him that he ejaculated so soon, too soon, he exploded a load of cum in his sister's mouth.
Not only couldn't he believe that he ejaculated in record time but also, even though it was expected that he did, he couldn't believe that his sister allowed him to cum in her mouth. Instead of pulling away and instead of spitting it out, she swallowed all of him. She swallowed his entire load of cum.
