"Ohhhh, Bud! That's heaven!"

Bud held her writhing body, his mouth wetting her neck. He kissed her until her mouth and chin were wet with his spit. He found one of her nipples, pinching it with his lips first, then wit his teeth.

"Whhuuhh!" Julie moaned.

As his sister bucked and wiggled, Bud moved faster too. He was fucking her with a quick thrusting rhythm that reminded Robyn all too clearly of what her brother had done to her that very morning. She was panting, rubbing her cunt while she watched the glistening red cock slide in and out of her friend's cunt.

Julie clung to her brother's shoulders and took huge lungfuls of air as if she couldn't get enough. The rubber Bud wore clung to him so tightly it was hard to tell he was wearing anything. Robyn watched him shave his prick into Julie as far as it would go. A shudder ran through the muscled boy's strong back.

"Ohhh, Julie!" he gasped. His ass gave a flurry of short, sharp jabbing movements. Robyn knew what was happening. The same thing seemed to be happening to Julie. She had her knees thrown wide and her ass was tightly pinched together with excitement.

"Whhhaaaaahh!" she cried, her eyes glazed with lust. She babbled something that had her brother's name included, then fell limp under his plunging, fucking spasms. Buddy kissed her slack mouth, moaning and groaning as he came.

Julie seemed to have fainted. For a moment, Robyn wondered if her friend had hurt herself. But as Bud kissed her face, the girl seemed to come around. Robyn stepped away from the door and backed cautiously down the hall. Her mind was a mass of confusion. She'd come aver to Julie's house to ask for advice, and, instead, she'd seen something that had mixed her up more than ever. Her poor cunt was so wet she could here it sliding together as she walked.
