Another game of "Greyhound."

Both girls were bent over the cushioned lounge sofa so without seeing who had the bald pussy I couldn't tell if it was Emily or Haley Bill was standing behind. I got behind the other twin and unceremoniously shoved my cock balls deep into her hot pussy, causing her to let out a loud moan of appreciation.

"Another round of 'Greyhound'?" Bill asked.

"Sure!" I nodded and fistbumped him.

We grabbed our respectively twin's wide hips and started hammering away at their wet, hot cunts.

I noticed Captain Bob had summoned his inner porn movie director by getting close-up shots of the girls' beautiful faces contort with erotic pleasure and their huge tits swinging wildly about as their pussies absorbed the violently pounding they were enduring.

"One!" Bill cheered as his twin let out an orgasmic cry.

I grabbed hold of my twin by the shoulders so she wouldn't fly forward when I slammed harder into her convulsing pussy. "One!"

Wanting to keep his lead, Bill grabbed his twin's arms to hold her upper body aloft and pull her back against his deep thrusts. "Two!"

As much as I enjoyed fucking my twin from behind I needed to change our position to catch up to Bill. I pushed her down, got her to roll on her side, and swung one of her long legs over my head -- all the while managing to keep my cock embedded in her pussy! "Hi, Haley!" I smiled down at her after noticing her blonde landing strip.

"Three!" Bill grunted over Emily's cries.

"Fuck me, Mike!" she growled, hooking her calves over my shoulders.

"Dammit," I muttered and immediately started pounding away at Haley's frothing cunt.

"OhGod," she repeated to the rhythm of my heavy balls slapping against her puckered asshole.

"Two!" I groaned at the sensation of her pussy spasming around my pistoning cock.

"Four!" Bill cheered.

I accelerated my thrusts and it barely registered to me that Bill had paused long enough to get Emily to lie down on her back on the sofa.

"Three!" I grunted.

"Cum for me, babe," Bill ordered as he hammered away at Emily's pussy.

"Oh OH OOOOOH!!!" Emily cried out, arching her back.

"FIVE!" Bill roared, slamming into her pussy one last time before he emptied his balls in her.

I always considered Bill more of a sprinter while I was a marathon runner -- he burned his energy to reach his orgasm more quickly while I took my time to make my partner climax more often before I came myself.

"Four," I muttered.

"Five..." Haley sighed when she climaxed again.

"SIX!" the two of us cheered in unison. She pulled me down of a kiss as I spurted a huge load of jizz into her womb.

When we all finally recovered, Bill and I pulled out and pushed ourselves off of the girls to survey our work -- the girls were lying on the sofa exhausted with the long legs sprawled wide apart, with sticky, white spunk drooling out of their reddened snatches.

Captain Bob, who had pulled out his big, black cock from his shorts, handed all four of us bottles of water to rehydrate. "Do you mind if I have a go at the girls, mon?"

"You're not going to fuck them, are you?" Bill asked defensively.

"No, mon! I'm happily married with four kids!" Captain Bob chuckled and pointed at his massive erection. "But my wife doesn't enjoy sucking dis!"

"It's okay," Haley smiled as she and her sister knelt down in front of the skipper.

"We enjoy sucking it!" Emily giggled and licked the length of Captain Bob's shaft while her sister sucked on his balls.

The captain pulled out his own phone to record the twins feasting on his cock.

Bill and I sat back to rehydrate and recoup our energies while watching the two blonde sisters pleasure the captain.
