“Let me see his pathetic little dick while he fucks you, sister” Tai laughed. “And they say Americans have big ones! Ha!”
“Ah, he’s plenty big for me, brother dear. Perhaps even bigger than yours.”

Tai did not look pleased with that, no matter what he was doing with Petty. “I’ll have to see about that myself later on,” Tai growled, throwing Petty aside and marching up to Timmy and Aiko. “It’s not like we have to worry about the fight going on too long.”

“Look, I’m not a girl, okay!?” Timmy pleaded once Aiko slid off of his cock.
“Shut your dick hole!” Aiko snapped, each of them grabbing an arm of his and beating away at his stomach. After multiple blows, Tai grabbed his balls and squeezed with a vengeance.

“Scream, American pig! Scream like the tiny woman you truly are!”
As Petty was starting to stand up, the Japanese twins swung Timmy by the arms, letting him collide with Petty and topple her over. Timmy was laid out over her upper body, too weakened to react yet and unknowingly pinning his own sister.

Aiko and Tai grinned as they went to Petty’s exposed legs, spreading them wide apart (one each) and hungrily digging into her warm young pussy, their tongues mingling inside her as Petty writhed in efforts to toss off her brother and escape.
