Coming of Age Sex Story: Chapter 7 - She wanted to be a cheerleader but her grades were too low. Summer school might solve that problem. But she needed a tutor to make sure. Her mom got a name from the school and he was hired. When they got to the biology tutoring, she wanted to understand the reproductive system. He was happy to teach her about it.

“Don’t hover,” said Delores as she frowned at Marcus. “Go check the burgers or coals or whatever it is men do at these things. Leave Mrs. Fitts and me to talk.”
“You have to call me Molly or I’ll feel like an old woman,” said Molly.
“I’m Delores. It’s a name from the forties. My great aunt had the same name.”
“I think it’s sad that the Florences and Madges and Tootsies of the world had their names retired. I don’t know any Henrys or Arthurs or Bud’s, either, and all those were great names.”
“Molly isn’t a common name,” Delores commented.
“My mother’s name was Melvina.” She pronounced it Melveena. “My great-grandfather wanted a boy named Melvin and when they got her they couldn’t call her Melvin, so it got turned into the female form of the name. My mother said she wasn’t going to saddle me with a name I couldn’t spell when I was five, so I got Molly. My mother swears it isn’t true, but my grandmother said they had a goat named Molly.”
“You don’t put on airs,” said Delores.
“Why should I? That’s no fun.”
The dish Delores had brought and the two plates of deviled eggs, all covered with Saran Wrap, had been taken by Molly and put on a folding table that had six chairs around it. The charcoal cooker was already going, but nothing was being cooked on it, yet. The meat was in a small cooler beside the cooker. There was another cooler with ice and an assortment of canned soda, tea, and water in it sat under one end of the table. Cups, plates, plastic flatware, and napkins made a pile in the middle of the table. Other than a linen tablecloth, there was nothing fancy about the setup. A wonderful scent filled the air and announced that Marcus had, in fact, found the meat and had begun to cook it.
“So. You wanted to talk to me about something,” said Molly.
“Yes. I have cultivated the kind of relationship with my son, in the absence of his father, that demands we communicate clearly, fully, and truthfully. He told me, among other things, about your little pool party. Please do not be upset about that. I demand that he tell me what’s going on in his life. It’s the only way I can be sure I can keep him alive.”
“I see,” said Molly, who felt her face get hot.
“What he’s doing with you and your daughter could get him killed.” Delores let that sit.
“By whom?” asked Molly.
“This isn’t the South, but that’s where I was raised, and I’ve seen ugly things involving white men and white women who have no use for a particular black man. I don’t think things are that dangerous here, in Ohio, but there are plenty of people who don’t think the mixing of the races should be legal.”
“I understand your concern,” said Molly. “By the way, I was raised in Belzoni, Mississippi. That is why I do understand your concern, but you may be perceiving something that isn’t quite real, yet. I assume Marcus also told you that my husband has been cheating on me. I only found this out recently but it has apparently been going on for several years. If I can prove it, I intend to file for divorce, but until then I am still married. The attraction between your son and me surprised ... no, astonished ... both of us. I did not date black boys when I was in high school. It wasn’t because I thought there was something wrong with them. My parents would have had strokes if I told them a black boy had asked me for a date and I accepted. Marcus was very thoughtful about this, and we discussed how things might happen in the future, depending on what happens in my life. I will not put him at risk by cheating on my husband. I have told him how ridiculous it is for us to even contemplate having a ... deeper ... relationship, but Mother Nature sneers at protestations of the ridiculous. For now, though, we plan no further ... uh ... escapades involving him and me.”
“I am comforted at your thoughtfulness about this,” said Delores. “I understand your daughter was also present.”
“Yes,” said Molly. “I wish I could adequately explain how this skinny dipping foolishness evolved, but I can’t. The whole thing started out a little like what’s going on between you and me. I wanted to talk to him because I could hear things in my daughter’s voice, when she talked about him, that made my radar turn on. All I wanted to do was poke around a little and see how he thought the tutoring was going and whether he thought she’d be ready for finals. I remember being in a swimsuit I shouldn’t have been wearing where a man could see it, and I remember the look in his eyes. He wasn’t crude. He was simply honest. And I couldn’t remember the last time my husband looked at me like that. His compliments were sincere and when Robin started barking at me for ogling him back a little, I asked him to take his shirt off. I said he had been able to evaluate us in our swim suits, and I wanted to evaluate him without his shirt on. I assume you’ve seen him without his shirt on.”
“Oh, yes,” said Delores.
“Well, I haven’t been around a man who looked like that since before I got married. In my current dissatisfaction with my husband’s behavior, I may have weakened a bit. No, it wasn’t weakness. I was exceptionally upset about my husband and your son is ten times the better man if they are compared. I knew what Marcus was thinking. All men think that way. But he was honest about it. He asked if we ever went skinny dipping in our pool and, suddenly, I wanted to do just that.”
“I have to ask if the fact that he was black had anything to do with this. Some white women get curious and just want to satisfy their curiosity.”
“I don’t think so. I didn’t really think about his race until he took his shorts off. Then all those crazy rumors floating around about how big black men are kind of popped into my mind.”
“I have seen him leaving the bathroom wearing much less than is proper,” said Delores.
“Well, seeing him was a first for me and I know it was a first for Robin. I think that, at this point in time, we were reveling in being able to be honest with each other. We swam and I felt things I knew were dangerous, so I laid down some rules.”
“What kind of rules?”
“He didn’t tell you?”
Delores shook her head.
“I said that, until my divorce was final, there could be no ... consummation ... of this new relationship. I included my daughter in that.”
“Didn’t you feel it was unusual that he’d want to be involved with both of you at the same time?”
“No. You have a daughter her age. You know what girls that age go through. It’s a minefield that can tear the bottom out of their hearts. It can ruin a woman for having a decent relationship with a man in the future. I know it wasn’t right, but when I looked at the kind of man Marcus is, I thought she couldn’t possibly do better in terms of exploring these new feelings with a boy her age. I trust him to treat her with respect and no other boy she goes on a date with will do that much. Was I wrong to do this? Have I put him in danger?”
Delores knew exactly how Marcus could affect a woman. She understood completely wanting for Marcus to “break a girl in” in a gentle, loving way. She knew how a woman of Molly’s age could feel about Marcus, because she felt the same way, herself.
“I think that any future relationship between Marcus and either of you would need to be handled very carefully.”
“Of course.”
“You’re quite a bit older than he is.”
“That’s obvious to everybody concerned. I did not jump into this thing because I was curious. No. That’s not exactly true. I did not jump into anything until he took his shorts off. He’s black everywhere, but has no impact on how he makes me feel. I’m not fulfilling some fantasy I had when I was a girl and I’m not rebelling against my parents’ attitude about the black race.”
“He says the words breeding and marriage never came into your conversation.” Delores watched closely to see how Molly reacted to those words.
“He’s way too young to think about marriage. He has a bright future. He’s a genius and he has a lot to offer the world. My daughter is sixteen. Would you discuss marriage with your daughter?”
“I would if some man had bred her and her belly was going to get big.”
“Well, I’m putting her on the pill, or maybe an IUD. Robin doesn’t need to start thinking about babies until she’s got some kind of degree and a job, but I know how strong the pull can and will be. He agreed to avoid intercourse until she’s at least eighteen, but I don’t think I’ll be able to wait that long so I’m quite sure they won’t be able to, either.”
“You’re sending her to college?”
“I don’t know. She isn’t excited about going on to four more years of education after high school. She has tossed around the idea of going to the technical school here in town. If she learns a trade, she might do better than if she gets a worthless four-year degree from one of the universities. They’re all liberal dumps. I don’t mean to insult you if you classify yourself as a liberal. I was very liberal in college, but the way liberals thought back then isn’t anywhere near the way the people who have hijacked the liberal cause think, today.”
“Liberals never did anything for the Negro,” said Delores. “It was democrats who formed the KKK. It was democrats who ran reconstruction and did everything in their power to keep the black man down and stupid. Democrats resisted integration. It was a Republican who freed the slaves. I could go on. That is why I think they should teach black history in high school. I think it is incredibly valuable if a young person understands exactly how this African American nonsense has come to pass.”
“We don’t have to vote the same way to be friends,” said Molly.
“I’m curious as to why you’d want to be friends,” said Delores.
“I have a feeling that, no matter how strictly we police his involvement with Robin and me, he’s going to stay in our lives for the foreseeable future. That is at least the upcoming school year, during which my daughter wants Marcus to become her boyfriend. That will raise some eyebrows, but she doesn’t care. I’m positive she’s never thought about the fact that her actions might put him in danger, but I’ll discuss that concept with her at length in the very near future. My point is that if he’s going to be involved in our lives, then we’ll be involved in yours, in some way, shape, or form. I would prefer that we try to be friends than adversaries.”
“I don’t want to be your adversary,” said Delores. “I only want to make sure my son isn’t getting in over his nappy little head.”
“I like him a lot,” said Molly, looking into the other woman’s eyes. “I like the way he makes me feel. I like the way he treats me with respect. I like the way we talk to each other. When we sit and talk the age difference just isn’t there. He is much more mature than his chronological age.” Molly wondered if Marcus had admitted to his mother that he had disclosed their incest to a strange, white woman. Rather than confront that, she decided to play dumb. “And though I can’t prove it,” she went on, “I think he’s had quite a bit of experience in things sexual. If you don’t know about that, you should interrogate him. If he’s doing things without your knowledge, that’s what could get him hurt.”
Delores liked this strange woman. Molly treated her like an equal and it wasn’t a put-on. She felt the strongest urge to tell Molly about where Marcus had gotten all that experience, but that was too dangerous. If, by some chance, Marcus and the girl ... or the woman ... formalized a relationship that was displayed as romantic, then sooner or later their little family secret would crawl out into the light. But Molly didn’t seem to care about whether things got taboo or not.
Delores also understood that very well.
“You’ll tell me if any attempted breeding goes on?”
“It’s refreshing to be able to be so above board with a woman my age. Most of my friends are always engaged in drama or gossip or judgement.”
“I suspect that’s because our backgrounds are so different we don’t know how to play those games with each other,” said Delores.
“I’ll let you know if I can’t control myself,” Molly said.
“You mentioned birth control for your daughter, but not for yourself.”
“One of the rules is that there will be no intercourse, period. Only other ways of relieving stress will be allowed. I won’t need any birth control until much later down the road, if ever.”
“And here I was beginning to think you had a good head on your shoulders,” said Delories.
“He makes me crazy. What can I say?” Molly smiled. “Thank you for being so understanding.”
“I don’t understand at all,” Delores lied. The truth could come out later, if it would ever help things. “It smells like the meat is almost done. Shall we call the kids together and eat?”
It was at that point that three screaming girls, dressed in bright bikinis, rushed out of the house and pushed a startled Marcus toward the pool.
They got him in, but he had all of them with his arms around them in a group hug when he got wet.
The food was eaten and the youngsters were back in the pool. The three girls were climbing on Marcus as if he was a mountain. His hands were going everywhere, goosing and stroking. Both women were watching and talking idly, comfortably, new friends despite the social hurdles. Molly had produced two bottles of wine and Delores had moaned that she hadn’t had the money to spend on wine for more than four years.
“This wine is so good!” Delores said. “It’s so good I’m drinking it too fast.”
Molly got up and weaved into the house. She brought out two more bottles.
“Here you go,” said Molly, setting them on the side table between them. “Take these home with you. Brad buys it by the case.”
Suddenly there was a squeal and the top of a bikini flew up in the air, rising above Marcus’s hand. The furor of climbing didn’t lessen even a little, but there was outrage in all three girls’ voices.
“I’m so sorry,” moaned Delores. “My children have not grown up in a restrictive environment. When their father took off I had more than enough to do. I had to decide what would be sacrificed and modesty was one of the things that went.”
“You mean they all run around naked around Marcus?”
“Yes. You must think I’m a horrible mother.”
