"Oh, Jesus, Sis!" he whispered, completely surrendering to her loving caresses when she momentarily released his tingling cock from her fingers. "Don't stop honey… don't stop!"

She was shocked at the expression on her brother's face. His mouth was gaping open, his lips drawn back from his teeth, while his glazed eyes rolled up crazily toward the ceiling.

Terri rapidly learned how to please him. The faster she stroked his cock, the wilder he shivered and lurched, and when she slowed down the action he would moan and beg for more.

"Oh, please don't stop!" he groaned when she again momentarily released his cock. "Oh, shit, honey, don't stop! Please, Sis, don't stop!"

Bob thought he would lose his mind with ecstasy as she brought him close to a climax time after time, only to let him slip back, then skillfully bring him up again.

"Jesus, Sis, that feels so good!" he panted as her soft fingers continued deliciously stroking the length of his throbbing prick.

As his body began lurching more violently, Terri instinctively moved her hand up and down over his big, straining cock. Crazed with wild excitement, she could feel her hot pussy juices oozing into her panties. She was pumping faster and faster while her brother lurched and moaned on the chair.

Bob could feel a wild orgasm building up deep in his balls. It felt as if his blistering prick was burning as his jizz started its fiery journey up through the tingling length of his cock.

"Oh, Sis!" he shouted in ecstasy as thick, hot cum gushed put from the end of his fuckshaft, splattering against her startled face.
