Pam opened her eyes and stared at her older sister. She gasped, frightened that Gloria would tell their mother.

Gloria was older and twice as horny as her little sister, Pam. "It looks like you discovered the secret of Gypsy's mouth I was wondering if you ever would."

Too nervous to hear what her sister had said, Pam scrambled for her clothes. "I thought you were staying at your girlfriend's house in town."

"She wound up with a date and I didn't feel like hanging around, watching her get fucked."

Pam's face filled with shock. She had never heard her sister talk like that.

"Don't bother getting dressed," Gloria said, a tinge of authority in her voice. "And you don't have to worry. I ain't telling Mom."

Pam stared unbelievingly at her older sister. "How come?"

"Because I do the same things with Gypsy, even more." Gloria smiled lewdly.

Pam was stunned. "You do?"

"Shit, yeah. You didn't invent it." She giggled.

Pam began to relax and forgot all about her clothes. "You sure you ain't telling Mom?"

"I told you. It'll be our secret." Gloria closed the door to the barn. "You still cherry?"

Pam nodded. "How about you?"

"I lost my cherry a long time ago." Pam was shocked, but the knowledge excited her. "When?" she gasped, feeling like an adult, talking to her older sister like this.

"When I was your age." She leered at Pam's small plump tits. "You're getting bigger."

Pam's cheeks flushed red. "Not as big as you," she said, gawking at her sister's big tits straining against the halter top.

"You will be when you're older," Gloria giggled. "Why don'tcha stand up and let me see you?"

Pam blushed a deeper red, but her embarrassment didn't stop her. She stood, shivered, then paraded around the barn, displaying her slim naked body to her older sister.

"You look terrific," Gloria said, a hint of passion creeping into her voice.
