Bill and Emily.

"One! Two! Three!" all four of us yelled out while we swung our fists up and down to the beat of the numbers before throwing out our hands.

"Rock!" I cheered.

"Paper!" Bill smirked.

"Scissors!" the twins cheered simultaneously.

"Does this mean I get both girls?" Bill chuckled.

"You're getting greedy, man!" I sighed, shaking my head.

The girls giggled and shouted out, "One! Two! Three!" again.

Emily threw out two fingers to form a "peace" sign while her sister laid out her hand flat.

"Scissors beat paper!" Emily cheered.

I wasn't insulted when I noticed Haley's frown -- I suspect it was typical sisterly competition.

"Well, we get the bigger bedroom!" Haley playfully stuck her tongue out at her sister while I offered my hand to help her up.

"Same size beds!" Emily retorted as she stood up to remove her long pink skirt, revealing she had nothing underneath except her bald snatch.

"Fine!" Haley rolled her eyes and pulled down her white mini pleated beach skirt -- unlike her sister, Haley had a thin, barely visible blonde landing strip, making it much easier to distinguish the twins naked!

Bill fistbumped me again. "We switch girls and rooms after, right?"

"Yeah," I nodded before Haley took my hand to lead me to the master stateroom, which was about only a dozen feet away but felt like a mile considering how anxious the two of us were to have my cock inside her pussy. Before we even made it into the stateroom, we could hear Emily grunting loudly after Bill shoved the full length of his cock into her.

Already consumed with lust, Haley was further perturbed that her sister started ahead of her so she dashed through the door and leapt on the bed.

"Fuck me with that big, fat cock!" the blonde purred, spreading her long legs wide apart to lure me in between them.
