[Coming home from studying abroad, I saw my wife's anus flapping open] After staying with a host family for several days, she gave in to temptation and had sex with a black man. The moment she leaned into him with anticipation, he suddenly thrust into her anus. An abnormally thick, upward-curving cock she'd never experienced before tore through her sphincter. Finished off with an extra-thick foreigner-only vibrator, her mind went blank. Then a massive black friend arrived, leading to a black man sandwich threesome. She tried to resist in broken English, but they didn't understand her.
