"Oh, sis!" he shouted in ecstasy as the thick hot cum gushed out from his big prick-head, splattering against her startled face. Thrilled by what was happening, she continued pumping frenziedly on his spurting prick until the last bit of jizz dribbled out.

Finally releasing her brother's rapidly shrinking prick, she began wiping her cum-drenched face with the back of her hand.

When she drew her hand across her mouth, she was delightfully pleased with the slightly salty, bitter-sweet taste of his jizz, remembering that Joyce had told her how good cum tasted.

Kirk was completely exhausted, his eyes closed and head thrown against the back of the chair as he slowly recovered from his intense climax. With his burning lust now relieved, he suddenly felt terribly ashamed for allowing his little sister to jack him off. Unable to look her in the eye, he stood up and closed his zipper. Still not saying a word to her, he walked upstairs to his room.

When he'd gone, Marci just sat on the floor for several minutes, trying to sort her thoughts out. It had been a traumatic experience for the young girl, yet jacking her brother off had been the most exciting thing that had ever happened to her. Finally pulling her cut-offs down, she lustily finger-fucked herself to a wonderful orgasm before going to bed.

Unable to sleep, she lay tossing and turning for hours. She was finally almost ready to fall asleep when she heard her bedroom door open.

"Who's there?" she whispered.

"It's me," she heard her brother answer as he closed the door behind him and walked over to the side of her bed.

"What do you want?" asked Marci turning on the bedside lamp.
