John and Nikki had first met at a science museum, a rather innocuous way for a pair such as this to meet, frankly. They both loved the exhibit about the solar system, and they shared their first kiss in a dark corridor behind the Planetarium a week later.
After a couple months, things had begun to heat up. They were making out on her parent's couch one Friday night while they were out of town. They trusted their 18-year-old daughter to be a good and studious girl. And she was - she was nothing but kind to everyone, and she never got less than a B+ on anything at school. But she was also a teenage girl with her first real boyfriend who wanted to get to know him much closer. At night, she had naughty dreams about the things she would do to him, and him to her.
While they were making out, with his tongue deep inside her throat and his hands under her bra cupping her round, supple C-cups, she threw her leg across his waist and straddled him, grinding her hips into his. At that point, she made a massive discovery - John's hard, throbbing cock under his jeans. She could feel its heat and thickness against her wet cunt, instinctively grinding harder into his crotch. She came just moments later, a warm wave pulsing through her hips. She was still a virgin, but knew right now that she no longer wanted to be one.
The next weekend, while her parents were at dinner, John arrived at her house. As he stepped inside, she grabbed his package and pulled him inside. "I want to kiss it, " she demanded.
But when they got to the bedroom, and he dropped his pants, her desire turned to shock. It was huge. Absolutely enormous. She gasped.
"How, how big is ... it?"
"I measured once. It was about ... 12 inches long." And it was, when fully erect. 12 inches long and 6 inches around.
Nikki reached out and grabbed it with one hand. She could barely get her hand all the way around it.
"How am I going to ..." She just couldn't imagine putting that huge member in her mouth.
"Are you scared of it? If so, I can put it away."
"No!" she shouted, louder than she intended. "I ... I'll try."
And with that, she leaned forward and took the swollen head into her mouth. The head alone nearly filled her mouth. She began to kiss it and rub it with her tongue. John shuddered. "Oh, oh, oh ..."
She kissed and sucked hard on his head for several minutes, stroking his member all the while. She could feel his cock getting harder as he got close to orgasm. Finally, hot cum exploded down her throat as he climaxed. She swallowed eagerly. They both smiled at what was the first real sex act either had experienced.
