"Swapping families is so much fun!" Becca practically guffawed after watching the swapped family five leave the beach after having a nice day out (not knowing they'd been anatomically scrambled). You nod in agreement, then feel yourself getting hard again as Becca takes aim at another couple of beachgoers.
Zzaaaaapppp!!!
The targets were a muscular young man of 19 year of age and his 14 year old sister following behind, too busy texting on her phone to notice the front of her bikini bottoms bulge out as her brother's impressive 8-inch schlong was transferred over. Her foreskin automatically rolled back and her bellend poked up out of her skimpy bikini as she got an immediate stiffy. Her brother shorts meanwhile had deflated in front, due to him now having his little sister's pussy between his manly thighs.
"She'd better change into some shorts or she'll be arrested for exposure." You chuckled at Becca, who was grinning smugly.
"I know right." Becca winked, as she spotted another family walking onto the beach. She practically salivated at the sight of the two thirty-something parents, their 17-year old daughter, 14-year old son and 10-year old daughter.
