Lynette didn't have much of a look at it at first. Betty took his cock in her fist and pulled hard, and when Mark howled in pain, she warned, "You better not tell about any of this, or I'll pull your darned cock right off!"

"I won't! Lemme go! Ow-w-w!"

Betty kept hold of his cock. And though she grinned in delight at Lynette, her tone of voice was still angry as she told him, "I might just pull it off anyway. It's so it wouldn't make any difference to you. Just look how tiny it is, Lynette. See?" Betty held his cock between two of her fingers and flopped it back and forth.

Lynette was fascinated. Though Mark's cock wasn't at all like the big, stiff cock she'd see plunging into Mrs. Cook's panties, looking at his fat, worm like cock made Lynette gasp and peer closer at it, while Mark helplessly squirmed his body under hers.

His cock had a sharp, tapered point that was all wrinkled up. Lynette leaned closer still. Betty did, too, as she pulled down on Mark's cock. His fat cock started bending. Betty pulled back his cock's tight sheath of skin, and a rosy pink knob appeared.

"There it is!" Betty said breathlessly. "There's his cock!"

Mark was weeping and wailing now, but both girls ignored his cries as they looked more closely at his cock. "How can he fuck us with a dinky old cock like that?" Betty wondered.

"Him? Fuck us?" said Lynette, astonished.

"Remember? We said we were going to fuck the next guy we saw."

"My brother?"

"Look!" Betty said, though Lynette was already looking quite closely. Mark cried out loudly as Betty pushed the skin of his cock farther down. The knob of his cock popped right up. Betty said, "He might not be too after all."

Betty started playing faster with Mark's cock. Mark's strugglings settled down into stead squirmings. Lynette thought back to how she had seen the terribly sexy and wicked Mrs. Cook suddenly swoop down to suck on Russ' cock. Before she could think about what she was doing, Lynette swooped down to suck Mark's cock.
