"Tab, get up on the bed and spread for this big boy," she ordered. "Chuck, put the prick to your aunt, now!" Neither Chuck nor Tabitha had to be told twice. While Pam loaded a fresh videotape into the camera and set it to begin recording again, Tabitha stretched out on her back on the bed, toes pointed skyward and legs open in a wide inviting "V". Grinning, Chuck knelt between her legs and pushed his cock slowly into her.
Tabitha looked over Chuck's shoulder at Pam as her nephew fucked her. She squealed with delight when she saw Pam rummage through the duffel bag and come up with the ten-inch black rubber strap-on dildo. Pam winked at her sister as she buckled the fake cock around her slender hips. She walked around the side of the bed and fed Tabitha the dildo. Tabitha eagerly slurped and swallowed the dildo as if it were a real cock. Pam chuckled, knowing that Tabitha's excitement had little to do with the blowjob and everything to do with what would come next. But Pam thoroughly enjoyed the illusion of fucking Tabitha's mouth. The redhead curled her fingers gently in her sister's blond hair. "That's the way to suck, Sis," she urged, guiding Tabitha's head back and forth. "Lube it up good."
"God that's hot," Chuck said as he watched his aunt drooling over the dildo.
Pam laughed and pulled away from Tabitha. "Dear sweet boy, you have*no* idea how hot it's gonna get." She climbed onto the bed behind Chuck and positioned the wet rubber head of the dildo between his ass-cheeks.
Chuck froze instantly. "Hey, no way!" he protested as his mother pressed the dildo against his asshole.
"Oh, more backtalk?" Pam wrapped her arms around Chuck's chest, playfully tweaking his nipples. "You wanna be cuffed up again?"
"No!" Chuck looked pleadingly over his shoulder at Pam. "Please don't, Mom!"
"You liked me fucking you with the vibrator when you were tied down," Tabitha countered, teasingly sliding her feet up and down the backs of Chuck's legs. "Admit it, honey, you loved it."
"No! Please!" Chuck repeated. Pam ignored him and with a hard shove of her hips drove the head of the fake cock into her son's tight asshole. He squealed and bucked forward, stabbing his huge cock into his aunt's pussy.
Pam pulled back and then drilled the entire length of the strap-on into Chuck's ass. Pam launched into a steady fucking motion as Tabitha locked her legs around her nephew and her sister, pounding her heels against Pam's wiggling ass. Chuck yelled and slammed crazily into Tabitha as if trying to escape the skewering motion of the dildo. "Fucking unbelievable!" Tabitha moaned. "Oh yes, oh Sis, keep assfucking your son just like that – he's fucking me like a maniac. Oh god oh yesyesyes – "
Pam rode Chuck's ass and beamed down at her sister's wild face. She felt as if she were directing Chuck's savage thrusts into Tabitha as if her son were her puppet. "It's like I'm fucking you myself," she said to her sister.
"Yeah," Tabitha's lips curled lasciviously and her eyes rolled back into her head.. "Fuck me, Sis. Fuck me with your son's giant cock."
So Pam did just that. Chuck had been tormented into amazing compliance, and although he continued to shout and whine he made no move to escape or disobey his mother in any way. Pam clamped his buttocks between her thighs and rode him hard. Chuck fucked back, moaning and crying as he shamefully fucked his aunt like a madman, his asshole stretched around his mother's fake cock. fucked him hard and fast, slamming the dildo in and out of Chuck's horny little anus.
"Fuck me, Pam! Fuck me, Chuck!" Tabitha pleaded. She pulled and twisted her big nipples in a frenzy as she humped her pussy up onto her nephew's cock. "Unngggh! Pam, make him do it harder – oh God! Ride him like a bull cause he's hung like a bull! I have to have it over and over forever fuck me please do it HARDER!"
Pam played with her son's balls as she fucked into him, and sensed by their tightness that her hung son would soon be blasting his aunt's pussy with a load of cum.
At that moment Tabitha shrieked "Coming! I'm – ah – god, coming – make him come for me, Sis. Shoot it up my cunt now!Pam leaned into her son's back, knowing just what would trigger his orgasm. She tongued his left ear and whispered to him. "You've been such a good boy, Mom's got a reward for you. Come for Aunt Tabitha now, and real soon I'm gonna have you fuck away your sister Tammy's cherry!"
Pam plunged hard into Chuck's ass one last time as, with a howl such as she'd never heard, he slammed his erupting cock into his aunt's tight pussy.
