I should really be first, but you're on.

Gary and Ben finished a lap and stopped, holding onto the side of the pool.

"Ok, so if I win, I get to fuck you first. If you win, you get to fuck me first." Gary said between breaths.

"That's what I said," Ben replied. "Are you game? Or are you chicken?"

"Well, I have actual experience, so I should go first," Gary said. "But what the heck, you're on. Start with a dive, down and back."

"All right!" Ben said.

Bernie raised her eyebrows. Usually Ben wasn't the competitive type, but he seemed to have challenged Gary. Was Ben jealous of her and Gary? She looked at Gary's naked sister Lillian, holding hands at her side.

Lil raised her eyebrows and squeezed Bernie's hand.

Gary crawled out of the pool, his naked pink body dripping onto the concrete pool deck. Ben followed, his golden skin equally nude.

"Hey Bernie," Gary said. "Can you judge a race? Ben and I are going to dive in and go down and back, one lap," he said.

Bernie looked over her two lovers, her boyfriend Gary and her cousin and longtime sexual playmate Ben, standing naked in front of her. Ben had a definite erection pumping up his circumcised penis, while Gary seemed just slightly aroused, his uncut cock drooping down at a four o'clock angle.

"Okay," she said. "Ready, then?"

Gary and Ben lined up side by side at the edge of the deep end of the pool. They bent their knees and raised their arms. Next to each other like this, Gary's greater height was obvious, as were the other contrasts -- Gary's straight blond hair and Ben's curly dark hair; Gary's slim build and Ben's more compact, denser build; and Ben's average-sized penis beside Gary's penis, larger than Ben's even while it was barely erect.

"One, two, three..." Bernie said. "GO!" she shouted together with Lil.

Gary and Ben dived into the water and swam like mad for the far side.

"Go, go!" Lil said, jumping up and down and waving her hands. Her small breasts joggled up and down with her vigorous activity.

Bernie watched quietly, her eyes intent on the two naked swimmers, who had turned the corner and were churning the water furiously, each trying to beat the other back to the starting point.

"Oh wow, oh wow!" Lil said, excited.

Bernie looked sharply as Gary and Ben approached her.
