Rachel, 18 and a senior at a private boarding high school, had always been shy and had never had a boyfriend. It's not that her parents didn't allow it, it's just that she was nervous. Nervous that boys would think she was a freak. She had a beautiful face with cute kissable lips and long brown hair. She was medium height with nice tan legs that ended in a beautiful round butt.
Above her butt was a tight little waist, kept slim by years of playing field hockey and lacrosse. But above the waist was what made Rachel feel like a freak.
Ever since puberty she had developed enormous breasts. Like Codi Vore enormous (look her up if you don't know). Her creamy white breasts were size 32L, but sagged only a bit, resting well above her belly button. Her areola were large and her big pink nipples were always erect, practically begging to be sucked.
She knew that some men liked big boobs, but didn't think anyone would like them as big as hers. She would soon find out how wrong she was. Rachael was also an incredibly horny teen, needing to masturbate several times a day despite being a virgin.
Her breasts and nipples featured prominently in all of her masturbation sessions, and were big enough that she could easily suck her own nipple while she touched herself, using her other free hand to caress the other breast. Rachael dreamed constantly of marrying a man who loved breasts and could suck her nipples while she fucked him.
Rachel's mom, Jessica, had divorced her dad when she was 10, and had dated around a bit, but hadn't gotten serious with anyone until she met Bill. Bill was kind and funny and strikingly handsome, and they quickly fell in love. Rachel took a liking to Bill, and so was delighted when Jessica told her, on her 18th birthday, that she and Bill were getting married, and that they would be moving in with him.
Bill, also a divorcee, had a son John, who had recently turned 19 and was taking a year off before college, working on a farm in Vermont. Because of how quickly Bill and Jessica has fallen for each other, John and Rachel had spent hardly any time together.
All that Rachel knew about John was that he was tall and handsome, like Bill, but quite shy. What she didn't know was that he had a big muscled chest and a meaty 9 inch cock. He also had an obsession with huge breasts, and dreamed constantly of marrying someone with giant titties that he could suck while he fucked her.
John and Rachael had still not met when, I'm 2020, a coronavirus started spreading around the world. Things quickly turned from interesting to weird to bad in March, and the timing could not have been worse for Bill and Jessica. They had just left on their first trip together as a couple, to Europe, when the whole world just about shut down. They ended up getting stuck in France with no chance of returning to the US soon.
John and Rachael both soon found themselves in the situation of many people their age at that time, camping out together at their parents' new house while they waited for the Covid pandemic to blow over.
John and Rachael took a quick liking to each other, both immediately finding an attraction to the other, both inside and out. The first few days of the pandemic were made much more bearable by their constant company, as they learned to appreciate each others' sense of humor and caring attitude.
Their parents had left strict instructions that neither John nor Rachael were to use their bedroom, insisting that they instead share the second bedroom which had two twin beds. This created a bit of awkward tension, with both John and Rachael having to change in the bathroom in the hallway.
Both John and Rachael had slept naked for their whole lives and in fact couldn't fall asleep with their clothes on, which they sheepishly admitted to each other on their first night sharing a room. As a result, they would get into bed each night with pajamas on, and would then strip under the covers so they could sleep in the nude.
Since both of them were young, horny teens, and were already deeply attracted to the other, each of them had to silently pleasure themselves to get to sleep. In fact each would also wake up several times throughout the night needing to touch themself to dispel naughty thoughts of fucking the other.
One night, just a few nights into their quarantine, the power in the house went out in the middle of the night and Rachael's alarm clock and night light go out with it. Rachael, naturally a problem solver, quickly wakes up and stumbles out of bed to leave the room and try to diagnose the issue. However, as she's new to sleeping in this bedroom, she trips on John's bed and as her upper body crashes forward, her breast swings forward and her nipple falls directly into John's open, sleeping, mouth. He involuntarily closes his mouth and they both moan with pleasure.
John awakes to the greatest sensation he has ever felt, a huge, natural breast covering his face with a thick, stiff nipple poking into his mouth, before he has even realized what's happening, his mouth had closed tightly over the nipple and started sucking. As he more fully woke up, he began to register that this was his new step-sister's enormous, beautiful breast in his face.
His curiosity about how this had come to be was quickly replaced by sheer pleasure and desire as Rachael whimpered in pleasure and grasped the back of John's head, desperately pulling him harder onto her breast. He sucked like his life depended on it, until he was about to pass out from lack of oxygen.
Calming down a bit after his initial rush of endorphins, he reached his hands up to caress the enormous, pillowy breast whose nipple he was sucking. He also switched from sucking to nibbling, kissing, and licking. He has no idea what she liked! But to his pleasure, she half whispered, half moaned, "just suck, baby. That's all I want."
John continued sucking and caressing, sucking and caressing. He had no idea how much time had gone by, but he was in absolute heaven. By this point he was obviously rock-hard, with just his thin sheet between his cock and the hot, sweaty air of the room.
But Rachael could tell it had been at least 15 minutes. She had never felt such pleasure in her entire life, and her naked pussy was literally dripping down the inside of her legs.
