Whitney, celebrating her 18th birthday with her family

"So, Whitney, today is your big day and me, your father and your brothers have planned a surprise for you tonight." Whitney's mom, Kelly, teased her as her two sons fucked her dp style.

"Ahhhh! Tell me, tell me, tell me please!" Whitney begged. She was beyond excited about today. Even though she already turned eighteen like seven hours ago, they were saving the big event for tonight. Although her mom had let her prance about nude after she got home from school when she actually did turn of age. There were some taboos no one dare break, after all.

"No sis, it's a surprise for a reason." Her older brother, Blake, spoke up as he thrusted in and out of their mother's rectum. "But trust us, sis, you'll enjoy it." His twin, Luke, said from under Kelly.
