Erotica Sex Story: Chapter 1 - 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?

It was Saturday night. Billy was resting with his hands behind his head when he heard a commotion coming from his mother’s bedroom. Billy’s big brother and sister sat up in bed.

Then they heard their mother screaming, her angry voice easily heard in their bedroom, “Get out, you bastard, and don’t ever talk to me again, you lying piece of shit.”

An equally loud male voice sounded almost as angry, “I’m leaving, I’m leaving, let me get my shoes.” Then there was the crash. “Jesus Christ, you almost hit me, you bitch.”

Billy started to giggle, and his brother Tim laughed and tried to suppress it. Then his sister Grace said what they already knew. “Well, there goes the second lamp this month.” They heard the front door slam shut.

They all got out of bed. It was time to console their mom. The three of them went to the living room and found their mother sitting on the couch in her favorite silk robe with blue, yellow, and red flowers. Their mother had her legs and arms crossed as she pouted like someone had stolen her chocolates. Grace sat on her left and put her arm around her. Billy’s big brother Tim sat on her right and did the same. Billy sat on the floor by her feet. Billy’s brother and sister moved in and kissed their mother, Sharon Kingsley, on the cheek at the same time as Billy kissed her knees because they all knew that tickled and made her squirm and laugh. She knew what was coming, and as hard as she tried not to, she laughed and hugged her children.

Tim asked, “What was it this time, Mom?”

“Married, just like the last one.” Sharon sighed as she leaned over and kissed Billy on the top of his head.

Their mother has never been lucky in love. Three times pregnant by the time she was twenty-five and never married. Sharon often said she never regretted the three love affairs that ended when Mr. Wonderful found out she was pregnant. She always said she felt blessed to have had three great kids she could not imagine living without.

Her three kids? Well, there’s Billy, age 14, his sister Grace, age 16, and his brother Tim, 17. Yes, they each had a different father, but that didn’t matter to them. The only one that matters besides their siblings is their mom.

Their mom will be 38 in a few months. They know she works hard and tries to give them all the things the other kids have. They have a laptop, but the whole family shares it. They are on a family phone plan, so they each have a phone with unlimited talk and text. Sharon thinks it’s essential to be able to reach everyone in case of an emergency. Sharon managed to raise three kids, work, and attend night school. She has an associate’s degree in administration and is the office manager for the local branch of a major insurance company. It doesn’t pay megabucks but has a matching 401K plan and good health insurance.

They live in a two-bedroom ranch in a quiet neighborhood. Sharon always threatened to finish part of the basement so Grace could have her own room. But somehow, the money was never there. The kids didn’t mind. To tell the truth, they liked being in the same room. They hung sheets on a clothesline to give Grace her privacy. Tim and Billy were in bunk beds. On the other side of the room was Grace and her twin bed. What was the big deal? They talked, joked, teased, and enjoyed each other’s company. Things only became a little weird when Grace first knew Tim was jerking off at night when he was 15. They all do it now, so it’s no big deal when they hear someone going at it. Sometimes, one will start, and the other two will join in. Yes, they know about sex. Tim even bragged to Grace and Billy the first time he felt up one of the girls that lived in the neighborhood. Billy was in awe of him. Grace called him a pervert.

Mom doesn’t hide what she is doing in her bedroom when she brings home the new guy she swears is the one. They know they are fucking because their mom is a little loud, and the only thing separating their room from hers is the bathroom. And the fact that Sharon warned them never to come in the room when she has a man in there because she was having sex, and sex was something you did in private. Sometimes, they masturbate while listening to their mom having sex.

As usual, Sharon was going to get over losing another round of find a good husband’ with her favorite indulgence. She led everyone into the kitchen like she always does and took out the ice cream. Sharon filled three bowls and passed them out. She took a serving spoon and started eating out of the carton. That half-gallon of cherry vanilla would be gone before she put that spoon down.

All the ice cream over the past few years might have something to do with the few extra pounds she said she was carrying. But being 5’ 8”, she could carry it. She had curly brunette hair cut short and a round face with big brown eyes, pouty lips, and freckles on her nose.

Billy thinks most of the extra weight settled in her nicely rounded ass. Her breasts are a C cup (Billy checked when she left a bra drying in the bathroom.) Billy liked when she didn’t wear a bra. Like now, he watched them jiggle under the silk robe as she ate her ice cream.

Something different happened tonight. Sharon waved her spoon at the kids and sounded pissed. “That’s it. No more men. No more sex. I have had it with these jerks. All they want to do is stick their dick in me until they find out I’m looking for a commitment. Then they tell me they are married, in another relationship, or not interested in a woman with three kids. I am just going to frig myself from now on.” Sharon stabbed her spoon into the carton to get another spoonful of ice cream, which she quickly consumed.

Their mom was not one to hold back when upset and had something on her mind that she felt she had to say.

It was then that Grace said something that surprised Billy and Tim. “But mom, you told me you liked the sex.” Apparently, mother and daughter would indulge in girl talk when the guys were not around.

Sharon waved the spoon around, “Well, who doesn’t like sex? It’s just that I expected more.” Another spoonful of ice cream disappeared.

Again, Sharon pointed her spoon at her offspring and lectured. “Now, you boys, make sure you don’t go sticking your dick in girls and give them false hopes. If all you want to do is fuck, tell them right up front, then no one will get hurt. You hear me, you two?”

Tim shrugged as he replied, “Sure, Mom, sounds like good advice.”

Billy kept quiet. He wasn’t sure he wanted his mother to know he was interested in fucking girls yet, even though his mother knew he jerked off. She was not very subtle the day she gave Billy a box of tissue and told him to stop using his underwear for cum rags. Billy was thankful she waited until Tim and Grace were not around to embarrass him.

So that’s the way it went. Their mother didn’t date, bring guys home, or go out on Saturday night.

Billy missed his seventeen-year-old babysitter. Barbara was kind of nerdy and nearsighted. She constantly adjusted her glasses as they slipped down her nose while studying. Billy liked her because she always sat with her legs open and let him check out her legs and panties. As soon as Grace, Tim, or his mother were home for the night, Barbara would close her legs, smile at Billy and wink. Then she was free to go. Now that his mother was home every Saturday night, Billy amused himself with X-Box.


It was a Saturday night, a little before 11:00, when Tim and Grace entered the bedroom to prepare for bed. Billy was already in bed. Billy knew Grace had come home earlier than expected from her date and had been watching TV with their mom. Grace went behind her sheets and put on her pajamas. Tim put his pajama bottoms on and got into bed.

Grace called to Tim, “Tim, can we talk for a minute?”

“Sure, talk away.”

Grace came out from behind the sheets and sat on the edge of Tim’s bed. “Johnny took out his cock and wanted me to jerk him off, but I said no and told him he had to take me home. (Johnny is 16 and has been dating Grace for a couple of months.)

Of course, that caught Billy’s attention as he listened to his brother and sister.

“Good for you, Sis, don’t do anything with him you don’t want to do. Do you want me to have a talk with him?”

“No, you don’t have to talk to him. I wanted to do it, but ... well, I was afraid I would embarrass myself because I have never done it before.”

“Hey, Sis, it’s no big deal. You just wrap your hand around it and move it up and down.”

“Can I watch you do it so I will know what to do?”

Billy smiled as he heard the surprise in Tim’s voice, “You want to watch me jerk off?”

“Shush, not so loud. Mom might hear us. Come on, Tim, I can hear you when you do it, and you can hear me when I do it. So what’s the big deal if you show me how to do it right?”

That’s when Billy leaned over the side of my bed and looked down at Grace. Grace looked up at Billy and whispered. “And you be quiet too, Snot-Nose.” (For some reason, Billy seemed to pick up a lot of nicknames) Billy pinched his lips together. Grace and Tim didn’t pay any further attention to Billy being there. They were together so much, and sex was so freely talked about with their mother and amongst themselves that Grace asking advice and Billy’s curiosity did not seem that unusual.

“Okay, Sis, if that’s what you want. Let me get it hard first.” Tim put his hand under his covers and was playing with himself. “Okay, it’s ready.” He pushed the sheet and blanket down and then his pajama bottoms. His hard cock was standing at attention.”

Grace’s eyebrows went up, “Wow, Tim, yours is bigger than Johnny’s.”

“Okay, Sis, it’s really simple. Just hold it and pump your hand up and down like this.” And that’s what Tim did to show his sister how to jerk off a cock. Grace watched closely, turned her head, and twisted her waist to observe what Tim was doing from different angles.

Then Grace asked something that really surprised Tim and Billy, “Can I try now?”

Tim was surprised at the request, but after demonstrating how to pump a guy’s cock in front of his sister, it didn’t seem that strange of a request, “Yeah, I guess so.” Tim let go of his cock. Grace reached out and took it in her hand. “Not so tight, Sis. Okay, that’s better. Now up and down but not too fast to start.”

“Like this?”

“Yeah, that’s pretty good.” Tim gave Grace more advice, “When Johnny is close to getting off, you should speed up. After he cums, you need to slow down again.”

“How do I know when he is getting close?”

“You will know, Sis. It’s kind of hard to explain, but you will know.”

“Will I know when you are going to cum?”

“You sure will if you keep doing it like that, Grace.”

Two minutes later, Grace had a pretty good idea of what was happening, “Oh, I think you’re going to cum.”

“Faster, Sis. Do it faster. Oh god, that’s good. Aaaagh.” Tim shot his load after thrusting up into Grace’s palm. Grace looked surprised but pleased with herself. She stopped pumping and let go of Tim’s cock.

“Don’t stop, Grace. Just slow down until it all comes out.”

“Okay.” Grace took Tim’s cock in her hand again, pumping it slowly as the last of the cum leaked out of Tim’s cock and over her fingers.

“Okay, Sis, that’s enough. It’s too sensitive now.” Tim started cleaning himself up with tissues, “See, pretty easy.” Then, he took out more tissues and handed them to Grace. Grace wiped her hand as Tim cleaned up his cock and belly. “Just don’t stop until Johnny tells you to. He will tell you how fast he wants you to do it and when he wants you to stop.”

“So, did I do it right?” It was obvious to Tim and Billy that she did, but Grace needed Tim’s assurance that she wouldn’t mess up when doing it for her boyfriend.

“Not bad, you got me off. I’m sure Johnny will like it when you do him.”

“Can we do it again? I think I can do better.”

“Not for an hour or so. Why don’t you practice on Billy? Hey, Squirt, do you want to let Grace jerk you off?”

Billy let his sister know he was all for it, “You can practice on me if you want. But I’m not as big as Tim.” Even though Grace loved Billy, she did ignore him most of the time. Billy loved his sister, so he would happily help her out.
