It was a Monday, and Jimmy Banks had spent the better part of the day biking around the city, enjoying his freedom. He had just graduated high school and intended to enjoy this summer before starting college. By late afternoon, as he headed home, he remembered his grandmother, Pam's request for some help moving things. Since her home was only two miles away, he decided to bike over.
When he arrived, he found his mom's car in the driveway. Finding the front door unlocked, he let himself in. And with no one in the living room, he moved on to the kitchen, which was equally deserted. But from there, he looked out the patio door to find them together, his mom's head in his grandmother's lap, and both topless. He realized that his mom was sucking on, and licking her mother's pendulous breasts.
He froze, unable to believe what he was seeing. His mom was absorbed in sucking on Gran's nipples as she, in turn, caressed her daughter's hair, looking at her adoringly, while her other hand fondled his mom's ample breasts.
Jimmy could feel his cock quickly grow hard as he continued watching. The scene was so erotic, yet so gentle and loving, as if mother and daughter were bonding over this intimate moment.
The thought of Gran seeing him in the kitchen sent a shiver through him and he carefully withdrew. He quickly bicycled home, and in his room, stripped and lay on the bed. He closed his eyes, replaying what he'd just seen in his head, as he jerked off. It didn't take long before ropes of his cum covered his chest and stomach.
He took a quick shower and dressed to await his mom.
It was almost seven when Jenny arrived home.
"Late day at work?" Jimmy asked, with a peck on her cheek.
"I went to see mom and catch up on things. Lost track of time, I guess. She asked me to remind you that you were supposed to help rearrange the patio."
"Yeah. Tomorrow morning. I won't forget this time," he replied, sheepishly.
"Give her a call and let her know you're coming."
Over dinner, Jenny noticed Jimmy was quieter than usual. "You okay?" she asked.
"What? Oh, uh... I guess I biked a lot today. Kinda tired."
"Well, rest up. Mom has some hard work for you tomorrow."
The next morning, Jimmy biked to his grandmother's house. She had retired from a successful real estate career some years back. Now, in her early sixties, she was enjoying life. "I made money so I could live comfortably, and to even pay for your college education," she once told him.
"Jimmy! Love! You don't need to knock. Door is always open for you." His grandmother beamed on seeing him. "You biked? I bought you a car for your eighteenth birthday!"
"Yeah, But it's only two miles. And I like it," he replied, giving her a hug.
"And keeping you fit. With a lean body like that, you must be batting girls away."
"Gran!" Jimmy laughed.
"Come! Work to do," she told him, as they headed to the patio.
He spent the morning moving planters and rearranging some furniture, including the sofa, which reminded him of Gran and is mom making love on it the day before.
"Done!" Pam declared. "And it's lunch time. Let's eat."
They sat at the patio table, where she watched her grandson scarf down the sandwich, she made for him, while they caught up on things.
"So, are you breaking any hearts lately?"
"Gran! Well, I hope not."
"Jimmy, I don't think you know just how much of a babe magnet you are. Well, maybe it's better you don't know."
But Pam could see something was on his mind. "Jimmy?"
"Gran... Uh, this is kinda awkward."
"Jimmy, I hope you know you can trust me."
Jimmy looked around, trying to find a way to say it. "Gran, uh, sorry it took so long to help you. But yesterday, I came by, and, well... I saw you and mom on the patio."
Pam's face went blank, then collected herself. "And what did you see?"
Jimmy paused again. "Your... Your tops were off, and mom's head was in your lap, and she was..." he trailed off.
"Making love to my breast?"
Jimmy nodded.
"I see. Well, we should have known that sooner or later you'd see us. It was easier when you were in school. What else did you see?"
"Nothing. I figured I had better leave."
"I see. You didn't see the rest. Hmm... Good thing, I think."
"The rest?" He asked.
"I think you can guess."
"How long have you been doing this?"
"Ah. Well, time to own up. I've always wanted you to be open with me; to know you have my confidence. And I hope I have yours," she asked. "Come, let's sit here," she added, pointing at the sofa.
"It started, oh, six years ago, not long after your mom and dad split. It started over wine. The conversation turned to my breastfeeding her and her breast feeding you. And how nice it felt, and the feelings of love and bonding. Perhaps, it was the wine, but I said, half-jokingly, it would be nice to feel it again.
"I could see in her eyes; she was ready to take the offer seriously. I hesitated. But the moment overcame me, and I pulled off my blouse. She undid my bra, letting her fingers glide over my breasts as she removed it. Then she put her head in my lap, just like you saw yesterday, and began kissing them. It wasn't long before she was really into it, sucking and licking. God, it felt so good, so sensual.
"It was like a renewal of our bonding, our love. I don't know how long that first time lasted, but I didn't want it to end. But it did, and I kissed her. So tender. I can't explain the feeling of that kiss, a mixture of love and arousal. Then I gave Jenny her turn.
"Ha! One thing she inherited from me was my tits! We switched places and I latched on to those glorious tits of hers! That first day was wonderful. I didn't care that it was my own daughter; it felt so loving.
"As you can guess, things progressed from there. The next time, she made love to my tits again. But this time, we started exploring each other's bodies. It wasn't long before we were pleasuring each other in ways that two women can.
"Well, that's how it started. And we've continued our little affair ever since."
Pam noticed her grandson staring at her chest, and, no doubt, her cleavage, exposed by her V-neck top.
"Penny for your thoughts?" Pam asked.
Jimmy blushed, realizing he was caught.
"Were you imagining your mom sucking on them? Or something else?"
Pam knew she was heading into dangerous waters. But she didn't care. Her own daughter was her lover. And if her own grandson wanted to suck on her breasts, she was more than happy to offer them.
"You got a glimpse of them yesterday. Want to see them again?"
