“So are you free Friday night, then?” Karen asked her next-door neighbor and best friend, Moira, as she sat across the small table in the kitchen breakfast nook. Karen and Moira had been having coffee together every morning since Karen moved in next door, and today was no exception.

“I wouldn’t miss it for the world!” Moira replied, smiling over her cup of coffee and her green eyes sparkling as she looked at her friend. “After all, it’s not every day that my best friend’s son turns 18, now is it?” she said, taking a sip out of her cup and then putting it down on the table.

“Good! I’m sure Timmy will be pleased that you’re there,” Karen said, also smiling as she took a sip out of her own coffee cup. “He’s had a crush on you for years, you know,” she said, one side of her mouth turning up in a smile.

“Yes, I know, and I’m very flattered,” Moira replied. Moira was 50 years old, 12 years older than Karen, but the age difference hadn’t stopped them from becoming best friends. “And now that he’s all grown up, you’re going to have to stop calling him ‘Timmy,’” she said.

“Yes, I guess you’re right,” Karen said. “After all, he is a man now, isn’t he?” she said, putting her own coffee cup down.

“Yes, he is,” Moira replied, her smile getting bigger.

‘And by the time I’m done with him he’ll be a man in more ways than one!’ Moira thought to herself. She’d had the hots for Tim for years, ever since Karen and her family had moved in next door three years ago. He was tall and lean, with dark hair, soft brown eyes and a slightly muscled build that made Moira’s heart beat faster and her nipples get hard every time she looked at him. As soon as she saw him she knew she wanted to fuck him, but she also knew that she had to wait until he was old enough.

And now that he was old enough, it was time to make her dreams – and his, too, hopefully – come true.

When Friday night rolled around and it was time for her to get ready for the party, Moira chose her outfit very carefully. She picked a dark red short sleeved dress with an incredibly large V-shaped scooped neckline that easily showed at least half of her more than generous bustline. Of course she wasn’t wearing a bra beneath it, so her huge breasts wobbled and swayed inside the dress with her every move which caused everyone who saw her to wonder what was keeping them in. The rest of the dress fit her snugly, showing off her curvy and slightly voluptuous figure, and since she always wore a thong there were no panty lines showing on her butt.

As she looked in the full-length mirror in her bedroom she liked what she saw. Her dark red (almost burgundy) hair was slightly wavy and came down to her shoulders, framing her face and accenting her green eyes. Her cheekbones were high, her nose pert, and her lips soft and full, a perfect fit to the rest of her face.

While most women with red hair were small busted, she was an exception to the rule. The last time she was measured for a custom fitted bra she measured 48 inches around her breasts and ended up wearing a 37J bra. Each breast was bigger than a man’s head, slightly longer than they were round, and weighed around six pounds each. They were capped with small, pale pink areolas surrounding a pair of perfect nipples that stood out prominently whenever they got hard, something that they did often. Moira had a very intense sex drive, one that her husband was unable to satisfy and which had led to him giving her his permission to satisfy it with the help of other men – as long as she told him about it later. Moira willingly agreed, and as she stood looking at herself in the mirror she could see her nipples getting hard and feel her smooth shaven, panty-clad pussy getting damp at the thought of what she was going to do to her best friend’s son.

“This is going to be a birthday he’ll never forget, that’s for sure!” she said to herself, one side of her mouth turning up into a sly, mischievous grin.

“I know that look,” her husband, Bill, said from the doorway behind her. “Who’s the lucky guy tonight?” he asked, leaning against the doorjamb and crossing his arms over his chest and his legs at the ankles, a smile on his face.

“Our next-door neighbor, Tim,” Moira said, smiling at Bill in the mirror. “Today is his 18^th birthday, and Karen is throwing a party for him. She invited me, and you just know I’m not going to turn that offer down!” she said, her smile getting bigger.

“No, I don’t imagine you would,” Bill said, crossing the room and standing in front of her, her massive chest almost touching his. “Just be careful and don’t get caught, okay, dear?” he said, holding her softly by her upper arms. She put her hands on his chest and looked up at him and smiled as she replied.

“I’ll be careful, I promise,” she replied, her green eyes sparkling. “And I’ll tell you all about it when I get home!” she said, her smile broadening.

“Looking forward to it!” Bill said. He bent over and kissed her quickly on the lips, then turned and walked out of the room towards his study. Moira turned back to the mirror and took one last look at her reflection, still smiling.

“Now let’s go get some nice, hard, teenage cock!” she said to herself, giggling. Then she turned and walked out of the room, her mammoth breasts bouncing inside her dress as she walked through the house and out of the front door, headed over to Karen’s house to fuck her son.

Moira had timed it so that she was fashionably late, and she could tell from the sounds coming through the front door that the birthday party was in full swing. She rang the doorbell and heard Karen call out ‘I’ll get it!’ from inside the house, and a few moments later the front door opened. Karen’s eyes flew open wide when she saw the dress that Moira was wearing, a big grin breaking out on her face as she spoke.

“Well! I guess I know what you’re giving Tim for his birthday!” Karen said, giggling.

“Think he’ll like it?” Moira said, putting her hands behind her back and rocking her shoulders from side to side, waving her huge breasts at Karen.

“If he doesn’t he isn’t human!” Karen said, looking down at the mammoth cleavage Moira was showing off. “You know every male in the house is going to want to fuck you as soon as they see you, right?” she said, lowering her voice a little.

“That’s the whole point!” Moira said, giggling. ’And as long as Tim is one of those men, I’ll be happy!’ she thought to herself.

“You are such a cock tease, Moira!” Karen said, laughing. “Well, don’t just stand there on the porch, come on in and let the men get a good look at you!” Karen said, taking her friend by the elbow and ushering her into the house.

As soon as they walked into the living room and the other guests got a look at Moira, all conversation stopped. Most of the guests were teenage boys with several of them having brought their dates, and if Moira had to guess she would have said that none of the males there were older than 19 with the exception of Karen’s husband, Frank. The males were all looking at her tits with awe and desire, the looks on their faces telling her that she had accomplished her goal. The looks on the girls’ faces, however, were something else entirely. If looks could have killed her head would have exploded. After a second or so of the pregnant pause Moira spoke up in a cheerful voice, a big smile on her face.

“Well, c’mon, guys, it’s not like you’ve never seen a pair of big tits before, now is it?” she said, holding her hands out as she spoke.

That did it. She got a collective laugh out of the males in the room and a few of the females as well, and the party returned to normal. Moira made a beeline for Tim, finding him standing on the far side of the room talking to a couple of other teenage boys. All eyes were focused on her mammoth chest, the huge, heavy mounds of her breasts swaying inside her dress as she walked towards them. The conversation they were having stopped when she reached them.

“So there’s the birthday boy! Happy birthday, Tim!” Moira said, holding her arms out and wrapping them around him to give him a hug, intentionally pressing her mammoth breasts up against him.

“Thank – thank you, Mrs. Moore,” Tim said, taken by surprise at both her forwardness and by the mass of breast flesh being pressed firmly against him. Moira held him at arm’s length as she replied, grinning from ear to ear.

“Moira, please,” she said, looking into his eyes, knowing that the way she was holding him was causing her breasts to be pushed together and up. “You’re an adult now, Tim, so you can call me by my first name!” she said, her eyes sparkling.

‘And in just a little while I’m going to make you a man as well!’ she thought to herself.

“Okay, Moira,” Tim replied, giving her a feeble smile as he was still unsure of how to act around her or how to respond. He was having a very hard time not staring at her massive cleavage, not knowing that her intent was to make him stare to begin with. All he knew was that Moira had the biggest pair of tits he’d ever seen, hands down. What she said and did next totally surprised him.

“And since I know you don’t have a girlfriend right now, I’m going to take it upon myself to be your date for the evening!” she said, slipping her arm through his and pressing the side of her huge breast firmly against his upper arm. Tim was at least six inches taller than she was, so the view of her cleavage as he looked down at her was nothing short of spectacular.

“O-okay, I guess,” Tim said, still not sure of what to say or how to act.

“So let’s go mingle, shall we?” Moira said, smiling up at him. Then she led him into the room, keeping her big breast pressed against his arm as they walked.

For the next hour Moira and Tim were the center of attention due to both Moira’s sparkling personality and, of course, her huge breasts as displayed by the dress she was wearing. Tim was the envy of every male there, and after a while he actually began to enjoy it. The longer he was with Moira the more comfortable he became, finally putting his hand on hers as it rested on her arm. Moira looked up at him and smiled when he did this, knowing what it meant.

‘And now it’s time to make you a man!’ she thought to herself, a sly smile crossing her face. She could feel her nipples beginning to get hard and her pussy starting to get damp at the thought of what was going to happen next. Just as she was trying to figure out how she could get them away from the crown unnoticed and where she was going to take him, Karen walked up to her from the side and whispered in her ear.

“Take him to my bedroom. Just try not to make too much noise, and don’t take too long!” Karen said. Then she was gone, disappearing back into the crowd of partygoers and leaving Moira dumbfounded.

“Oh, we’re gonna talk about this later!” she said softly to herself, a sly smile forming on her face.

“I’m sorry, what was that?” Tim said, looking down at her.

“Oh, nothing, just mumbling to myself, that’s all,” Moira said, smiling up at him. “Come with me,” she said, pulling on Tim’s arm and leading him away from the crowd in the living room and down the hallway to Karen’s bedroom.

“What’s up? Where are we going?” Tim asked, curious.

“You’ll see!” Moira said, smiling up at him as they arrived at the door to Karen’s bedroom. She opened the bedroom door and pushed Tim inside, stepping in behind him and closing the door behind her, making sure to turn the lock as she did. When Tim turned and looked at her he saw the mischievous smile on her face and the strange look in her eyes; he also saw that her nipples were hard as rocks and poking out prominently against the material of the red dress she was wearing.

“Moira, what’s going on? Why are we in my mom’s bedroom, and why did you lock the door?” Tim asked, his inexperience and naivete showing through like a beacon in the night.

“We’re in your mom’s bedroom because I can’t give you your birthday present with others standing around,” Moira replied, her voice soft and sultry as she slowly walked over to where Tim stood at the foot of the bed, never taking her eyes off of his as she spoke. “And I locked the door so we won’t be disturbed,” she said, standing in front of him and putting her hands on his chest as she looked up at him.

“What ... what’s my birthday present?” Tim asked, the light of realization slowly coming on.

“Me,” Moira replied, stepping close enough that her huge breasts were touching his chest. “I’m your birthday present, Tim,” she said, her voice low and sultry. “Aren’t you going to unwrap me?” she said, a sly smile on her face.

“Moira, I don’t think...” he began, but she stopped him with a finger to his lips.

“SSHHHHH,” she shushed, still smiling. “Here, let me help you,” she said, taking his hands and putting them on her mammoth breasts. She squeezed his hands with hers to get him going, and sighed when she felt his hands tighten on her breasts.

“That’s right, sweetheart, that’s right!” Moira cooed, looking up at him and smiling. “Squeeze those big tits, squeeze them hard!” she urged, with Tim doing just that.

Tim couldn’t believe what was happening. Moira Moore had been his secret crush for as long as she’d been living next door, and he had lost track of the number of times he’d dreamed about her and her huge tits. And now here he was, her tits in his hands, with her begging him to squeeze them.

‘Holy shit, they’re firm! And heavy! Wow!’ he thought to himself, looking down at Moira’s face as he squeezed and massaged her massive mounds in his hands. Her eyes were closed and her head was tilted back with a satisfied smile on her face, making it obvious that she was enjoying this as much as he was. Then she opened her eyes and looked at him as she spoke, again taking him by surprise.

“Here, let me make it easier for you,” she said as she pulled the dress covering her breasts aside, revealing them to Tim in all their naked glory.

“Holy shit!” Tim said softly, his eyes opening wide at the sight of Moira’s huge, naked tits.

“Bet you’ve never seen boobs as big as these before, have you, sweetheart?” she asked, a lopsided grin on her face.

“No, never!” Tim replied, looking up at her briefly before looking down at her tits again. He slid his hands under the massive globes and lifted them up, astounded by both their firmness and incredible weight. He ran his thumbs over the hard nipples, making Moira close her eyes and moan, a smile on her face.

“Mmmmm, that feels nice!” she said, opening her eyes and looking up at him. Then she reached out and put the palm of her hand against his crotch, pleased to discover that he was already getting hard. She rubbed the lump of his hardening cock firmly through his pants, urging him to full hardness.

“Does that feel good, Tim?” she asked breathlessly. Tim was squeezing her mammoth globes hard again, rubbing the nipples with his thumbs, making her pussy get wetter by the moment.

“Yes, it does,” Tim replied, nodding.

“Well, if you think that feels good, you’re going to love what’s coming next!” Moira said, looking up at him with a big smile on her face.

Without another word she dropped to her knees in front of him and quickly opened the fly of his pants, pulling the zipper down and then reaching inside to grab his semi-erect cock with her hand. She wrapped her fingers around the semi-hard shaft and then pulled it out, smiling when she saw Tim’s cock for the first time.

“Oh, my,” she said, her smile getting bigger as she gripped his rapidly growing cock in her hand. “You’ve got a great prick, Tim!” she said, looking up at him as she spoke, then looking back down at his cock. She could feel it getting bigger, thicker, and harder as she gripped it with her hand, squeezing it firmly. She began pumping it slowly, urging him to full hardness. She slid her free hand inside his pants and scooped out his balls, massaging and squeezing them as she pumped his cock.

Tim watched as Moira pumped his cock with one hand and massaged his balls with the other, and it didn’t take long before he was fully erect. His cock throbbed in Moira’s hand as the blood rushed through it, and she squeezed his cock harder in response. A few moments later a big drop of clear precum appeared at the slit in the tip of his cock, much to Moira’s delight.

“Oh, yes, now that’s what I love to see!” she said, grinning from ear to ear as she looked up at him. Then she looked back down at his cock, and without hesitation she stuck out her tongue and licked the drop of precum from the tip, making him jump.

“Wow!” Tim gasped as Moira licked the precum from his cock. Moira couldn’t help but giggle at his reaction, smiling as she looked up at him and spoke.

“Let me guess, you’ve never had that done to you before, either,” she said, still gripping and pumping his cock with her hand.

“Are you kidding?” Tim said, the frustration showing in his voice. “I can hardly get my girlfriend to touch me there, much less do what you’re doing!” he said.

“So you’ve never had a blowjob before, then?” she asked, licking the underside of the head of his cock for emphasis and making him jump again.
