Donna sat at her kitchen table, crying. She had just found a pair of another girl's panties in Eric's room. He insisted they weren't his, but she knew better. She had seen the way he stared at other girls when he thought she wasn't looking -- waitresses with less than fully buttoned blouses, roller girls in the park with their long legs and tiny little shorts.
It wasn't that she even minded the thought of him with another girl (or girls). Donna was just afraid that if he liked other girls more, he would leave her. Aside from the regular good dicking, he was also her best friend. She didn't really think that he would leave her out in the cold, but the mere possibility terrified her.
Just as she resolved that she would not let that happen, whatever the cost, her mother walked in. Noticing Donna's swollen eyes and wet face, Midge sat down beside her daughter and nuzzled the 18-year old into her chest. Today, Midge's usual tight fitting sweater contained an oval cutout, showing her smooth, tanned and freckled cleavage. Donna had always admired her mother's breasts, and with her face buried in them she couldn't help but notice how they were soft and yet firm.
"What's the matter sweetheart?" Midge asked.
"Mom," Donna mumbled into Midge's chest. "How do you keep a man from leaving you?"
"Leaving me? No man has ever left me!"
"I know, mom! How do you do it?"
"Well, I look like this!" Midge said, squeezing on her breasts, pressing them even harder into Donna's face.
Donna raised her head. "I look good too, Mom. Maybe I'm not as built as you, but I'm close. But the way I figure it, there is just too much variety out there for a man to stick to any one person. Even if he can eat steak every night, what if he wants pizza every now and then? Or Mexican food?"
"Ohhhh. Well, you father does love to have sex with Mexicans every now and then."
"Mooom, gross!"
"Well, he does! I don't mind. He would never leave me."
"I don't mind if Eric sleeps with other girls sometimes, either. But how can I make sure that he never leaves me?"
"Well, when he sleeps with other girls, it helps if you're always involved."
"You mean like, watching?" Donna asked.
"Ohhh, no. I mean like sucking on his balls while the other girl sucks on his cock!"
"Mom, gross! We're talking about dad!"
"Well, you asked. And anyway, it's not that gross. You're father has a huge cock."
"It's gross to ME, Mom!"
"Oh, of course. I'm sorry dear."
"So that's it? Multi-girl blowjobs?"
"Well, it also helps to have a common interest. You should show that you are into the other girls as much as he is. Do you like to eat pussy and titty Donna?"
"Well, there was the time when I shared a room with Jackie."
"Oh, you would fool around with Jackie?"
More like fuck the shit out of each other, nearly every night. "Some."
"That's great! I'm so glad you're open-minded and willing to explore your sexuality."
"Uhm, yeah." Remembering Jackie made her wet. Maybe she could start by fucking Eric along with Jackie. Jackie and Eric had never really gotten along, but Jackie was the kind of girl that once she got turned on, she would do pretty much anything. The memory of Jackie with dildos frantically going in and out of both her ass and pussy made Donna smile. She was going to have to go use some of those dildos herself later, maybe while looking at the Polaroids they had taken.
Midge interrupted her thoughts, saying mischievously, "You want to know a secret? I used to fuck Jackie too.!"
"What?! Jackie? That little slut!"
"Tee hee! She sure was. I would make her wear a maid costume and eat my pussy while calling me 'Seniorita'!"
"That was MY maid costume! I wear it for Eric!"
"I bet you look great in it took, dear. It was a little loose on her. I'm sure you just fill it to bursting! In a good way, of course."
Donna decided to let it go. In fact, the mental image of Jackie going down on her mother like that was turning her on even more. Donna had always appreciated that Midge was a beautiful woman. She could hardly blame Jackie for acting a little slutty to get a piece.
"That's another thing that will help you keep your man, Donna. Be a real slut. Be depraved, and make sure it all centers around his cock."
"But this is the 70s! Women should be equal to men. Or better!"
"Oh, honey, I find that women are often better than men." Midge winked. "But no matter how you act in other areas of your relationship, you have to be a major slut for your man in the bedroom."
"I'm not sure how to go about it. I've already done some pretty dirty things. He fucks me in the ass a lot, and I love it. I play with myself for him, and I wear crotchless panties a lot -- when I wear panties at all."
"That's a start, hon, but it's really not enough. Even anal sex seems kind of vanilla, after a while. I'll tell you what. I'll help. "
"What will you do?"
"How about this? We invite Eric over. You hide in your closet and I'll bring him up to your room. Then I'll screw his brains out while you watch, showing you the kind of stuff you can do!"
