Chapter 4

Erotica Sex Story: Chapter 4 - Sharon Kingsley, mother of three, was fed up with deceitful men and their broken promises. As she expressed it to her children, her solution was, “That’s it. No more men. No more sex. I’m just going to frig myself.” For such a lovely and passionate woman, a very sensible answer to her problem… Right?

Sharon woke up the next morning at around 7:00. She checked on Billy and saw that he was still asleep in Grace’s sleeping bag. She crawled out of her sleeping bag and put on a pair of shorts, flip-flops, and a pullover. She grabbed a towel and soap and walked down to the bathhouse. Sharon stripped off her shorts and pullover and put them in a locker. She went into the women’s common shower area, just wearing flip-flops. There were eight showerheads in this cinder block building.

Sharon was almost done when Grace came in, adjusted the water temperature and started to wash. Sharon couldn’t help but notice what a beautiful young lady Grace had turned into. Sharon smiled at her daughter, then giggled, and they both laughed.

Sharon finally got ahold of herself, “Now stop that, Grace, it’s not funny.” But Sharon couldn’t stop smiling. “I don’t know what came over me to allow you to do such a thing.” Sharon hesitated but decided she needed to talk to someone. “I guess I should tell you I’m feeling guilty about what I did last night.”

“You did it with Billy?” Grace asked as she grinned.

“Of course not. He had an erection, and well, I told him it was okay to masturbate. Grace, I watched him do it. I watched the whole time. I should have turned my back, but I didn’t.”

Grace put some shampoo in her hand and started washing her hair, “I don’t feel guilty at all. I love them both, and I don’t care that they are my brothers or what others might think. And you should not feel guilty either. We are all we have in this world.”

“Well, you better care because if anyone finds out, we will be in a lot of trouble.”

“I know, Mom.”

Just then, another woman came in with her young daughter.

“We will talk later.” Sharon rinsed off the last of the soap, went into the locker area, got her towel, and dried off. She dressed and waited for Grace. A few minutes later, Grace came out of the shower room. Sharon waited for Grace to dress before they walked to their campsite.

Grace was surprised her Mom confessed that she watched Billy jerk off. She wanted to ask her more about how she felt about what she did, but Grace didn’t want to make her think she did anything wrong.

As soon as Grace and Sharon were back from the bathhouse, they started getting breakfast ready. Breakfast was cereal, Juice, and coffee for everyone but Billy. Billy had milk instead of coffee. Billy was in a hurry to go down to the beach to collect seashells. Sharon told Billy and Tim to shower, and then they could go. Grace helped Sharon clean up from breakfast and straightened out the campsite. When Tim and Billy got back, the kids put on their windbreakers and the three of them headed for the beach. The tide was out. It was a good time to collect shells.

They had a plastic pail a quarter full before anyone said anything about last night. The beach was practically deserted at this early hour. They could talk without worrying that someone would hear. Tim broke the ice. He wasn’t convinced what Billy told him was true.

Tim tossed a shell into Billy’s pail, “Did you really do it with Mom there last night?”

“Yeah, Mom said it was okay.”

“How was it? I mean, with Mom watching. Was she really into it?”

Billy shrugged, “I don’t know.”

“Believe it, Tim. Mom and I talked this morning. She told me about watching Billy jerk off, and I could tell she liked it. She is feeling guilty about it. But I bet she would do it again if given the chance. But don’t push it. Mom is still a little nervous about all of this. Remember, she just found out about us last night. She’s willing to let the three of us fool around, but we have to be smart about it and keep it a secret.

“I hear you,” Tim replied.

“Moms are supposed to lock up kids that do what we are doing. So let Mom decide if and when she wants to do something with us.” Grace pointed her finger at Billy, “And you too, Mr. Hot Pants.”

“I hear you, Sis.” Billy was well aware of his habit of spilling out his thoughts before thinking when around his family. Billy tended to keep his thoughts to himself around non-family members. He was even considered shy.

Tim agreed with his sister, “You’re right, Sis. I thought we were dead meat last night when Mom caught us. If I didn’t know that Billy did not know how to lie, I wouldn’t believe Mom told him it was okay to jerk off and then watch.

Billy took offense to that statement, “I do too, know how to lie.”

“Not to us, you don’t.”

It was getting a little warmer, and more folks came down to the beach. The kids returned to their campsite and put on their bathing suits.

They had a typical day at the beach. It was about 9:00 pm when Grace went into the boy’s tent with Billy. That left Sharon sitting with Tim. Knowing what Billy and Grace were up to in the boy’s tent made the evening feel awkward. About an hour later, Grace came out and sat at the picnic table with Tim and Sharon. Sharon looked at Grace and raised an eyebrow.

“He’s sleeping.”

Around 11:00, Tim went to bed. Grace and Sharon went into their tent, put on their nightshirts, and got in their sleeping bags. Sharon couldn’t stop thinking about Grace taking Billy into the boy’s tent. “Grace, are you planning on doing one of the boys every night? That seems a bit excessive to me.”

“Of course not, Mom. I didn’t even do Billy tonight. We fooled around and kissed. Well, it was me kissing him most of the time. When I was ready, he licked my pussy, and then I gave him a blow job. I won’t want to go all the way for a couple of days now. Two or three times a week is plenty with those two, but I do love fooling around with them.”

Sharon laughed, “I can imagine. Sorry about asking all the personal questions, but ... I worry about whether I made the right decision.”

“You’re my Mom; of course, you’re going to ask personal questions. And I’m fine with that.”

“And the other thing is ... I was uncomfortable when you left me alone with Tim. Every time he looked at me, I felt like he was waiting for me to invite him into my tent.”

“Tim was waiting for you to invite him into your tent. And don’t worry, he will wait until you’re ready.”

Sharon didn’t know how to reply to that. It was as if Grace assumed she would have sex with Tim. Sharon nodded as if in acceptance. A gestor that Grace interpreted as her mother’s weakening defenses. After all, her mother had practically admitted to being aroused while watching Billy jerk off.


Except for an unexpected 15-minute rain shower, which delighted the beachgoers on that hot afternoon, it was another perfect day at the beach.

It was getting late when they decided they had enough of playing cards. Grace went into the boy’s tent with Tim. Sharon wondered if it was Tim’s turn to get a blowjob or if they were going to go all the way. Billy helped his mother clean up the picnic table and asked, “Mom, can I sleep in your tent tonight? I don’t want to wait for Grace and Tim to stop fooling around.”

Not giving it much thought, as she picked up the cards, Sharon answered, “Yes, that might be best.”

When Sharon and Billy entered her tent, Billy took off his shorts. He rubbed himself and put his hand in his underwear. Sharon thought, <i>So that’s what he meant by he couldn’t wait.

Sharon could not help herself. Billy was so damn cute and so open and honest. Sharon smiled as she started to pull her jersey over her head. She watched her son playing with himself. “Do you need to take care of that, Honey?” The thought of watching him jerk off again was not unappealing to Sharon.

“Can I? You let me do it before.”

“Yes, I guess I did. Oh hell, go ahead, I don’t mind.” Sharon turned the Coleman lantern down too low.

You had to love Billy’s complete lack of inhabitations in actions and words when around his family. He laid on Grace’s sleeping bag, pushed his underwear down and spread his legs just a bit before taking his cock in his hand to masturbate. Sharon pulled her jersey up and over her head and set it aside. Billy was looking at her. She let him look at her bra-covered boobs. She saw him smile. Sharon didn’t bother turning her back to him this time. Billy stroked his cock as he watched his mother. Sharon took off her bra and slid her thumbs over her nipples as she watched the shadowy image of Billy playing with himself.

Sharon let out a sigh as Billy watched her touch herself. It didn’t bother her that he watched her as she watched him stroke his cock. He may seem a little naïve at times, but he was not a virgin anymore. Sharon knew Grace was fucking him, and they had oral sex. “You don’t mind, do you, Billy? Mommy likes to play before she goes to bed sometimes.”

“It’s okay, Mom. Are you going to play with your kitty like Grace does?”

Grace’s words echoed in my head. Actually, Billy is just as good. You should try it.

“Yes, honey, I think I will.” Sharon got in her sleeping bag, took off her shorts and panties and spread her legs. Although she covered herself to her waist, she knew Billy could tell what she was about to do. She made no pretense that she was watching him as they played with themselves.

Sharon was encouraged by Billy’s remark. The fact that he didn’t seem a bit surprised that she would do something like that with him washed away any misgivings she might have had about what she was going to ask of her son, “Would you like to come over here and help your mom feel good like you do for Grace. Can you do that for me?”

“Okay. What do you want me to do? Lick you or fuck you?”

Sharon couldn’t bring herself to answer that question as plainly as Billy had asked it. The sleeping bag was unzipped, so Sharon just threw back what was covering her and exposed her naked body to her son as she held her hand out to Billy, “Come over here, Billy.” Billy let go of his hard cock and came over and knelt beside his mother. Sharon took his hand, “Get on top of me, Billy.” Billy got in position between his mother’s legs.

“Geez, Mom, you’re awfully pretty.”

“Thank you, sweetheart. I like hearing that from you. You’re my handsome boy.

“You really think I’m handsome?”

“Yes, you are very handsome. Are you ready?” Sharon didn’t see; the speak first, think later, foot-in-mouth, awkward son he usually is. She saw a young boy growing up. Capable of making love to his sister and now his mother. He was as tall as she is now. Another year, and he would tower over her.

“Grace likes to put it in for me,” Billy informed his mother.

Sharon reached down and took her son’s cock in her hand and guided it to her love hole. Sharon could not help but wonder how many times Billy had fucked his sister. “Right there, honey, push it in.” Billy did as he was told and started moving his hips and fucking Sharon with his not-yet-fully-mature six-inch but very adequate cock. Sharon could not help but think about it as she got that wonderful feeling she gets when making love. Grace was right. It is good.

Billy pressed his cheek against Sharon’s breasts. Sharon wrapped her arm around him and kissed the top of his head. “Oh, sweetie, this is so nice. Now I know why Grace likes doing it with you.”

“I like doing it with you too, Mom. I really like your boobs. They are nice and soft and feel so good. Do you want me to tell you when I’m going to cum. Grace likes me to tell her when I am going to do it. Sometimes, she wants me to take it out and do it in her mouth.”

Sharon hugged him a little tighter and kissed his cheek. “Honey, I think tonight you should just do it in me. I don’t want you to take it out. I like it where it is.” Sharon closed her eyes and reveled in how sex with her fourteen-year-old boy was as good as with many of the men who had passed through her bedroom door. Sharon felt Billy’s lips on her nipple. Again, she let out a sigh of pleasure. “That’s my baby. Do that. Mommy likes it when you do that.” Sharon would find it hard to explain how good sex with Billy felt. The way he moved as if just to pleasure her, although she knew he was taking great pleasure in fucking his mother. Sharon felt his cock moving faster in her pussy, his hips were bouncing, and his breathing got deeper. He was going to get off.

“I’m going to cum, Mom.”

Sharon wrapped her legs around his legs. “That’s it, sweetheart, do it in mommy. Oh, that feels so good. Sharon felt his hot cum shoot into her as he thrust his cock deep into her pussy for the last time and let his full weight press on her chest. Sharon held him there and reached down and put her hand on his butt. “Don’t move, Honey. Keep it in me for just a little longer. Sharon squeezed her butt together and milked his cock with her pussy. She was close. Billy’s hips started to move again. Three more butt clenches and her pussy hugged his cock of its own accord. She had to bite her lip, or Grace and Tim would hear her as her body reveled in the orgasm and pleasure of sex with someone she loved. Finally, she loosened her grip on Billy and relaxed her body. Billy sighed, rolled off her, and lay by her side.

“Wow, Mom, that was awesome.”

“Yes, it certainly was.” Sharon put her arm around Billy and hugged him. “Can you keep a secret, Honey?”

“Sure, Mom. I kept it secret that Tim and I were having sex with Grace until she told you. She even put a curse on me so I wouldn’t tell.”

“Will I have to put a curse on you?”

“Nah, they don’t really work. Grace puts a lot of curses on me.”

“Let’s not tell Grace and Tim what we did. Okay?”

“Okay, so you’re not going to do it with, Tim?”

“I don’t know. Maybe. I have to think about what we did.” Sharon reached out and fondled his cock playfully. “Maybe you’re all mommy needs.” Much to Sharon’s surprise, his cock started to get hard again. “Well now, maybe you are more than Mommy needs.” Sharon continued to play with it as he reached out to play with her breasts. After Billy’s more than satisfactory performance, Sharon was delighted their night of sex wasn’t over. “Stand up, Billy. You said Grace puts your cock in her mouth?”

“Yeah. I like when she does that.”

Billy stood up. Sharon got on her knees before sitting back just a bit, putting Billy’s cock at eye level. She only had to lift her chin to lick the shaft and then the glans. Sharon licked it and sucked it, knowing it would be a while until he could cum again. She didn’t care. She was enjoying licking and sucking his cock as it got harder in her mouth. Sharon let his cock fall out of her mouth and said, “I wanted to do this for you, but only until you are ready to make love. Do you think you can put it in me again?”

“Sure, Mom.”

Sharon knew she was out of control but didn’t care. Maybe tomorrow she would care, but not tonight. Tonight she just wanted to suck Billy’s cock and fuck. Men had shat on her for her whole life. Tonight, she was with someone who loved her and would never lie to her. What more could a woman ask for? Damn the cynics and naysayers, Sharon was going to make love to her fourteen-year-old son, and she knew this wouldn’t be the only time.

Sharon sucked and licked his boy cock slowly and gently. Sometimes, using her tongue on the tip to lick the pee hole. She could not get enough of this boy. He started to make little fucking motions. Sharon wrapped her lips around his cock and let him fuck her mouth as she worked her tongue. He was ready. She held his boyish hips and pushed him away. “Lay down, honey.” Billy lay on his back and held his cock. He watched his mother approach him. Billy couldn’t take his eyes off of his naked mother. He thought she was so beautiful and sexy. What his mother was doing was all new to Billy. When he fooled around with Grace, he knew they were done after he fucked her. Grace only sucked his cock before fucking. Grace never asked him to do it a second time.
