The next morning Barb made coffee and started making breakfast. She poured two cups and took them to Don and Lisa's rooms to wake them up. They came out to the kitchen just as Barb was dishing up.
Besides the usual exchange of 'good mornings', Don and Lisa didn't say anything while they were having breakfast. Barb finally got to the topic she wanted to talk about.
"Look. I know both of you are adults now. And I know you are both old enough to make your own decisions. I would like to ask just one thing. Please, and I mean PLEASE," looking at Don "I only ask that you don't put that," nodding toward his lap "inside that." nodding at Lisa's lap.
"There are a number of ways to relieve sexual urges that don't include intercourse. It would be a disaster for Lisa to get pregnant. For all of us. So please, just don't go there. Okay?"
Looking at the table, Don said "So. Like what you and Lisa did last week is, you know, okay? But just not have intercourse?"
Lisa looked at Barb with a surprised expression like Barb was the one that spilled their secret to Don. Barb had a similar expression looking at Lisa. They quickly realized neither had said anything to Don.
Barb replied "What do you know about last week?"
"When I got up, I heard you. I did take a peek to see what it was." he said.
"I see." After a long pause Barb continued "Well, I guess it isn't a secret anymore, then. Yes. We have been available for each other for a couple years. We both have needs, and this way, we can help each other. And Lisa can't get pregnant with me."
"Or you, too?" Don added.
"No, I can't get pregnant anymore. Look, until last week, we've never even seen each other completely naked. But we have been helping each other to relieve our urges."
While Don was processing these images in his mind, Barb continued "Back to what I wanted to discuss. There are times when we can be there for each other. I get it. We're all adults and we are all sexual beings and that's okay. I only ask that you two draw the line at intercourse."
Both Don and Lisa looked at each other nodding and said okay.
"I want both of you to know, I'm here for you, too. What we did last night was really something. I'm glad we could do that, and I think we can again. That is, if you want."
Don and Lisa looked at each other again smiling. Not their usual smile, but a loving smile that warmed both of their hearts. Barb noticed this change as well. She realized this brought the family so much closer than they have ever been before. It wasn't just three people living under the same roof anymore, or just three roommates, it was three people that truly love and care for each other in a new way.
After breakfast, Don and Lisa cleaned up the kitchen together. Barb sat at the counter as they all chatted. For the first time in years, they were enjoying each other's company as a close family.

That evening, Don turned on the TV to watch a movie shirtless in his gym shorts with no underwear on under them. There were two chairs facing each other with a couch and coffee table between them He sat in a chair next to the couch.
Barb and Lisa came in a few minutes later. They were both wearing over-sized t-shirts, ready for bed. Barb sat in the chair opposite Don and Lisa took the center of the couch.
It wasn't long before Lisa noticed a new bulge in Don's shorts. She looked at her mom. Barb noticed Lisa out the corner of her eye looking at her. Barb turned her head to see if Lisa wanted her attention. Lisa had a big grin and used her eyes to direct Barb to look at Don.
Barb had a better view since she was directly across from Don. She could see up the leg of his shorts. She saw the head of Don's cock almost coming out of his shorts. Barb looked back at Lisa and gave her a knowing grin.
Barb wanted to have a little of fun with this. She changed from crossed legs to placing both feet on the floor then relaxing her knees, opening the view for Don to see up her night shirt. She was wearing panties, but knew he would want to look anyway.
Barb gave Lisa a wink then returned to watching TV but kept watching Don out the corner of her eye. As she hoped, Don did notice his mom with her legs opened and started staring at her pantie covered pussy.
It wasn't long before the head of Don's cock was past the end of the shorts and exposed. Lisa noticed his cock peeking out the leg of his shorts and instinctively slid her hand down to rub her pussy through her panties as she stared at it.
Barb looked at Don. Their eyes met. Then she lowered her eyes to his shorts.
"Looks like you need to take care of that." she said staring at the head of his cock peeking out the leg of his shorts.
She stood up and slipped her panties off and sat back down opening her knees. Barb began tracing the outline of her pussy with her finger. She could see Don trying to adjust his cock in his shorts.
"Y'know, you might as well take him out so you can take care of him." she said.
Don stood for a second and slipped his shorts off releasing his very hard, and long erection.
They both heard Lisa say "Damn!" under her breath when she saw it. She quickly slipped her panties off and sat back down spreading her legs wide.
Don turned the TV off to eliminate the distractions. All sat quiet as they looked at each other's bodies and masturbated together.
He admired Lisa's young woman pussy and his mom's mature woman pussy. He noticed his mom's clitoris standing at attention. It was hard for him to look at anything else. He was fascinated how it stood straight up and protruded from her lips.
It wasn't but a few seconds later, Barb and Don heard Lisa making grunting and gurgling sounds. Her knees slammed shut with her hand jammed between her thighs. They watched and could see her body quivering.
That made Don start jerking faster. Barb put her legs over the arms of the chair spreading wide with her cunt pointing directly at Don. She started fucking her vagina with her two middle fingers slapping against her clit with the palm of her hand.
Staring at his mothers gaping pussy being fucked by her fingers, Don couldn't last any longer, he grunted out "Oh shit, OH SHIT! UGHhhhh!"
Barb saw Don erupting cum all over his chest. That was the icing on the cake. Barb began convulsing as a huge orgasm rushed through her body. Don kept stroking as he watched his mother being consumed by her own orgasm. He kept jerking until he was completely drained and his body went limp in the chair. Barb put her feet down and sank back into the chair catching her breath.
They all sat quiet for a full minute or two before Barb said "Well. I think my point earlier has been made. There are ways to relieve yourselves that don't include intercourse." After a short pause she continued "I don't know about yow two, but I'm tired. I'm going to bed."
