Seduced by sis
Amy Marshal held her boyfriend's cock with both hands, feeling the gigantic shaft throb. Slowly, she pulled back the loose foreskin which sheathed the gigantic knob and touched the glistening surface with the tip of her tongue.
"Oh, Keith," she whispered, nuzzling her face into the wiry crotch, "it's so big and… delicious!"
"Suck it, Amy," the boy said, placing both hands behind her head. "See you can lick it all the way in."
Although Amy knew that would be impossible, her hunger made her at least try. She opened her mouth as wide as possible and sank her lips down the rubbery slab of dick, feeling it pulsate even more violently, squeezing her lips painfully apart. When his cockhead reached her tonsils, her throat closed suddenly, gagging her. She took a deep breath and pulled back up, spitting the prick onto his stomach.
"I… I can't do it," she said, almost mournfully, eyeing the monstrous column of cock. "I'll choke to death."
"Just keep sucking," the boy said, pushing her face back down to his prick. "Unless you're ready for me to fuck out that little cherry of yours."
Amy shivered, almost forgetting why she had called Keith in the first place.
She had been talking with her best friend, Sherri, and the subject had, naturally, gotten around to boys – and this particular boy, Keith Rogers.
"Go ahead," Sherri had urged, her eyes glistening with anticipation. "Ask him to take you to the drive-in and do it. I bet he'd do it… so good!"
At first, Amy had balked. She felt this was the biggest decision she had ever had to make, and it frightened her. It wasn't just the pain she feared, but what might happen if her family ever found out, especially her brother. He was studying to be a minister, and had lately been watching her like a hawk, expressing unusual concern over her virtue.
