A week had passed since Peggy had brought Billy in to work to give him a present.
She had let him get under her desk and worship her feet. He had taken it upon himself to kiss up her inner thighs, and got very close to her pussy. In that moment, Peggy wanted to lift up her skirt, tear off her panties, grab Billy by the back of the head, and force his face into her pussy. She knew he would gladly eat her. Peggy told Billy she knew about him taking her panties and sniffing them at home. Billy was shocked she knew, but she reassured him it was OK. Talking about it made Peggy lose all sense, as she had pulled her panties aside and asked Billy to eat her. Peggy was lucky not to be caught by her boss as he left. She was also lucky because it left the office empty for Peggy and her son. She had beckoned her son to go down on her as she sat on top of her desk, and he did so like an expert. She had never had her pussy eaten that good. She had squirted all over his face, and he swallowed every drop he could. Like mother, like son.
Everyday since then, as Peggy sat at her desk, she kept replaying what happened in her mind. She fingered herself, picturing her son tonguing her pussy as she laid on top of her desk with her legs spread as wide as she could. Peggy was falling behind on her work because she couldn't take her mind off her son and what they had done, and what she wanted to do with him. She had to go to the bathroom several times a day at work to cum into the toilet. She squirted so much, she couldn't do it at her desk and make a mess.
Something else had happened that day with Billy that she also couldn't get out of her mind. After he had devoured her pussy, and made her cum all over him, Billy had asked her a question. He had asked if the next time something happened between them, if she would let him lick her dirty asshole. Hearing that from her son made her shudder with excitement. Ass eating was a taboo many people wouldn't cross, especially with an unwashed asshole, but Billy was asking for it. Her son was depraved, and she loved it. She understood Billy meant he wanted to lick her ass at the end of the day when it was sweaty, and some odor had built up. She wanted to let Billy do this as much for her pleasure as it would be for his. She had never been with any man or woman who was into ass eating, and she had always been curious how it felt. She knew that with Billy's tongue skills, it would be marvelous.
Peggy had decided to let a week pass before she tried anything sexual again with her son. She felt that maybe she was moving things forward too fast for him, and that he needed time to really think things over. He may have been caught up in the moments because he was a virgin, and was just doing these things out of uncontrollable emotions. Billy seemed completely normal all the days since, and she felt confident that if he really changed his mind about her, he would tell her. Plus this week sexual hiatus from her son was making her climbing the walls.
Peggy decided that today after work was a good day to resume her line crossing with her little boy. Peggy had to work late, and didn't get out until 6pm. When she got home, she kicked off her pumps she had started wearing since that day with Billy at work. She could tell Billy really enjoyed the way her feet looked in them, and as a bonus, the leather made her feet sweat even more than her canvas flats.
Peggy grabbed a glass of water and quickly chugged it down. She was nervous, and her throat always got dry when she was this anxious. She made her way up the the stairs and straight to Billy's door. She could hear his video game blaring. She knocked a few times, but received no answer. She opened the door and Billy was sitting on his computer chair wearing his headset, listening to his MP3 player, while also playing his game. How he could handle all that noise at once was beyond her. She walked up behind him, and tapped him on the shoulder. Billy was startled, and spun his chair around quickly.
"Oh hey mom. You scared me there for a second. I didn't hear you knock."
"How could you hear me with all that noise blasting in your ear?"
"Sorry mom."
"Remember Billy, call me mommy."
"You got it mommy. So what's up?"
"Well, I just wanted to know what your thoughts are, and how you feel about what has happened between us lately. We've crossed a lot of lines that mother and son should never cross in most people's eyes. Are you freaked out, disgusted, upset? Do you want whatever is happening between us to stop?"
Billy jumped out of his chair.
"No Mommy please! I don't want it to stop. I want everything that's happening between us. I have for years! I'll do anything you want!"
Peggy hugged Billy tight and started stroking his hair.
"Don't worry baby boy, nothing is going to stop. I just wanted to make sure you weren't confused, or bothered by what happened after thinking it over."
"No mommy, I'm happier than ever!"
Peggy smiled and kissed Billy on the cheek. Her arms were still wrapped around his waist. He looked in her eyes, and put his right hand on her cheek.
"You are so beautiful mommy."
Billy leaned in and kissed Peggy on her bright red lips. It caught Peggy off guard, but she did her best not to react and make Billy feel he had done something wrong.
"Thank you Billy that was sweet," Peggy said with a smile.
Without a word Billy moved his hand from his mother's cheek to the back of her head and slowly drew her in. He paused for a moment, and then put his lips to hers. Peggy had little time to think before he parted her lips with his tongue. Peggy instinctively met his tongue with hers, while her grip on her sons waist tightened. Mother and son were kissing for the first time. But this was not the type of kiss most mother's and sons share. This kiss was a kiss that people deeply in love share. Their tongues danced with each other with incestuous passion, neither of them taking a break to breathe. Both were lost in each other.
