"I can't!" Arlene wailed, the sound tortured. "I just can't!"

Peggy held her sobbing sister again, caressing her soft hair and down her back, letting Arlene cry it out. Her hand wandered lower, and she felt the rise of her sister's hip. She felt, too, the trembling against her, heard a quick intake of breath against her tit.

"Peggy," Arlene said in gulping, sobbing, softness. "When we were young, I… remember how sometimes we had to sleep in the same bed?"

"I remember," Peggy said.

It had not happened often, but sometimes Arlene would sneak into bed with her at night, cuddling warmly.

"I used to… oh, I'm so ashamed!"

"It's okay, Arlene," Peggy soothed. "It's okay."

"No, it isn't! Peggy, I can't keep it to myself any longer. I've got to tell you."

"Then tell me," Peggy urged.

"You're going to hate me," Arlene whispered. "You're going to really hate me, I know."

"No, I won't," Peggy assured her sister.

Peggy waited, stroking her sister, sliding her palm up and down her back and side, touching her hip lightly.

"I used to…" Arlene drew in a deep breath. "It was so nice being close to you in that narrow bed. I loved to feel you next to me. You were so warm and comforting. One time, I… oh, Peggy, I touched you!"

"Touched me? Where?"

"On your… between your legs," Arlene sobbed pitifully.

Surprise showed in Peggy's eyes. She hadn't known that.

"I wanted to touch… to feel you, and you were sleeping and I lifted your gown real careful, and touched you between your legs. You had panties on, but I could feel how hot it was and… I rubbed you a little."

Peggy felt herself responding to her sister's confession. She had not know her sister was so sensual. It seemed there was a lot she had not known about Arlene. Apparently they both had done the same things with boys, both wanting them, both waiting until they were married to get fucked. And now Arlene wasn't having orgasms with her second husband, and she needed to orgasm desperately. That part Peggy could understand very well.
