At this point Steve realized that his dominate position in his relationship with his sister was just an illusion and he was never really in charge, Nicky had always come first. He realized that if he wanted to continue his illicit affair with his sister, he was always going to have to take second place to Nicky. Steve was unwilling to give his sister up completely, he knelt behind Beth and started licking her ripe, swollen pussy.
Their senses were in overdrive as oral sex became the focus of their activity. The heady aroma of musk filled Beth's nose and made her head spin with desire, while her son moaned in pleasure as she sucked at his throbbing member. Meanwhile, Steve's face was covered in Beth's slippery, sweet juices from her ripe pussy, which he just could not get enough of.
For Nicky, this was the first time any woman had touched him sexually, the feel of his mother's wet, firm mouth on his manhood was like heaven, the smell of her arousal was a new odor to him, one that he decided he liked and wanted more of. Nicky exploded into his mother's mouth, filling it with his hot load, which she then proudly showed him before swallowing it in one large visible gulp. Beth's orgasm followed shortly after, as her brother continued his intense devotion to her peach. Beth then concentrated on finishing Steve orally, bringing him to his own climax.
Steve wanted to fuck Beth, but she resisted, telling him that she did not want her first time with Nicky to be sloppy seconds. Steve, understood and satisfied with a blow job, got dressed, said his goodbyes, and left them alone for the rest of the evening.
After Steve left, Nicky and Beth got cleaned up, taking separate showers and returning to the living room fully dressed. Watching a bit of TV, Nicky snuggled up next to his mother, kissed her while asking to feel her boobs. In response, Beth removed her shirt and bra, and spent the rest of the evening topless, telling her son that he could play with her tits anytime he wanted, on the condition that he had to be topless as well. Nicky agreed and removed his shirt.
As they continued cuddling and watching TV, Nicky's attention was solely on his topless mother. At dinner time, he barely noticed what he was eating as he could not take his eyes off of her exposed skin. After they finished eating and cleaning the dishes, Beth shooed Nicky into the living room while she prepared dessert.
When Beth called him back into the kitchen, Nicky was surprised to find her with honey on one nipple, and chocolate syrup on the other. Nicky was stunned, he had never thought about food as being sexy, now it was irresistible. Starting on her chocolate nipple before it could drip on to her stomach, he devoured his mother's breast, using his lips to get all the dark, sweet liquid from every inch of her boob. He then moved to her other breast, running his tongue around her stiff nipple, taking his time to lick the sticky gel that clung to her nipple. Beth then urged her son to remove his shorts so she could lick honey from his dick. The moans filling the room revealed the pleasure each of them got from this bit of play.
After the food play, both covered in a sticky mess, they needed a shower, this time, together. Using their hands and body soap, they made sure to get every nook and cranny. Nicky knelt in front of his mom to make sure her muffin was clean; he could not resist running his fingers and tongue over her bare pussy. Though he had felt her crotch on getting home that day, this was his first taste, he eagerly lapped at it, recalling the honey from her tits, while one was sweeter, the other was more flavorful, he hoped to have both at the same time soon.
Drying off, Nicky learned that his mother preferred gentle pats on the skin, compared to a vigorous rubbing he was used to. Hand in hand they left the bathroom and Beth guided them to her bedroom.
Once in the bedroom, she lay on the bed and held out her arms, welcoming her son to join her. As he went to his mother's arms, she told him she had had enough foreplay, and it was time to fuck. She spread her legs, took his penis in her hand, and guided him into her wet and warm pussy. The ridges along his cock ignited in a hot and snug feeling as each inch entered her. Once fully inside, his penis felt like it was held tightly and firmly in a sheath made just to house him. As he instinctively started to withdrawal, he could the friction as it pulled at the head of his cock, resisting his escape, then back in again, feeling the heat welcoming him back. This being his first time, he came all too soon, flooding his mother's pussy with his frothy semen. But she encouraged him to continue making love to her, and soon he was hard again, this time taking much longer. She started coming while he was still working up to his next load, he could feel her muscles clinching at his penis, squeezing tighter against his cock, until he coated the insides of his mother's pussy again.
Exhausted, they fell asleep in each other's arms.
Nicky's life has changed, now each day, he rushes home to his topless mother and greets her with a kiss and a gentle cupping of her tits, before they settle into spending the evening together.
Steve still comes around from time to time, usually during the day while Nicky is in school, and he will occasionally join them in a threesome, he knows that when Nicky was home, Beth devotes the majority of her time to her son.
