Thirteen years old:
Darlene was sixteen, the daughter of a neighbor, and she was there to "babysit" Adam and his four younger brothers and sisters. An hour after the parents were gone, though...
Darlene told the other kids to go play in the back yard, then led Adam into his own bedroom. They explored the inside of each other's mouths with their tongues. Darlene let Adam run his hands all up under her T-shirt, along her back and shoulders, feel the bra keeping her tits loosely in place.
Of course, he had trouble with the bra clasp.
She smiled, then undid the bra clasp herself.
They sucked face with their shirts off. Eventually, though, off came the jeans.
Darlene ran her hand along Adam's stiff shaft. Then,
The back door opened, then slammed shut again.
"Darly!" Quentin, Adam's younger brother, yelled. "I'm hungry! Make me a sandwich!"
"Make your own damned sandwich!" Darlene yelled back, her voice an octave higher than usual due to being excited about the sex she was about to have.
"I want you to do it!"
"I'm coming, damn it! I'm coming!"
Darlene got on top of Adam to slide his dick up into her, her huge tits flopping, her mouth open and gasping for air. Darlene convulsed slightly as she climaxed, and the sight of that made Adam come, his virginity now officially lost forever.
Her back to him, suddenly shy, Darlene lit a cigarette as she quickly dressed. Adam saw a bit of lit tobacco, no bigger than an infant's toenail, fall from the cigarette to drop to the floor.
It glowed bright red.
