The girls' backs arched and they almost strangled themselves as they strained against the rope that bound their necks together. Their eyes shot open and they gasped in pain, their assholes burning up, their guts churning as the boys buggered them.
The boys laughed, giddy, dizzy from the pleasure shooting through their plunging cocks.
"This is better than pussy!" Bobby moaned. "'Course it is!" Todd said. "Give me a bitch's asshole any old day. Fuck!"
The boys fucked as if they had motors in their loins, humped like a pair of stud hounds. Their hugely swollen cocks sliced in the assholes of the squirming, gasping girls, plunged and screwed and made squishing noises as the girls' assholes got juicier from the buggering. The tight bellies of the boys pounded the girls' asses, jolted the girls and made their tits flap. The girls gasped and whimpered, helpless to stop the rigid cocks from fucking them.
Nada couldn't help herself. Her emotions and feelings were in such a turmoil that her bladder let go. Hot piss gushed down her legs and pooled around her knees on the concrete. She blubbered like a baby.
"Holy shit!" Bobby said. He grabbed at her crotch, filled his cupped hand with girl-piss, then lifted his hand and rubbed the piss all over his belly, all over Nada's ass.
"You fucked the piss outa her," Todd said. He slapped Marilyn's back with the flat of his hand, almost knocking the wind out of her. "Piss, bitch! Piss like your girlfriend!"
Marilyn had no trouble letting go. In fact, she welcomed the chance to relieve her bladder. As the piss ran down her legs, Todd chuckled dementedly and caught handfuls of it, which he slapped on her back, on her ass, in Nada's face. Bobby caught more of Nada's piss and threw it in Marilyn's face. The boys laughed, their bodies flushed with lust and sadistic excitement.
The girls winced from the pin that was splashed in their eyes. They winced even harder as the boys renewed the savage attack on their assholes. Shivers passed through the girls' bodies as the big cocks jack hammered inside them, reaming out their assholes, turning their bowels to jelly.
"Feels good!" Bobby moaned, a dazed expression on his face as he thrust his cock repeatedly into Nada's seething guts. Such intense quivers shot through his cock that he felt the fuck-sensations all the way to his toes.
"Let's cream 'em," Todd said, humping like a bull. "Let's blow their fucking heads off?"
"Yeahhh!" said Bobby. "Let's shoot 'em up!"
The fingernails of the boys sank into the tender flesh of the girls' waists and hips. The boys' bellies smacked savagely. The boys' cocks plunged, disappearing to the hilt with each grinding stroke.
"I'm close!" Bobby gasped. "I'm-I'm coming!"
"Yeahhhhhh!" growled Todd. "Fuck!"
The boys snapped their heads back, rolled back their eyes, and rammed their cocks in so deep that the girls thought the cock-heads would come out their mouth. Molten fuck-cream exploded from the cocks of the two boys and splattered in the girls' guts. The boys grunted and bellowed like two young bulls getting off for the first time. The girls jerked with each powerful ejaculation into their bowels.
Thank God it's almost over! the girls were both thinking. But as the cum-spurting turned to cum-oozing, as the cocks began to soften inside them, the girls began to feel let down. They realized their pussies were throbbing, their pussies were leaking. They realized they were horny. They needed to get off themselves!
The spent boys slumped over Marilyn and Nada, grinding their bellies against the girls' asses, pleasuring their softening cocks in the tightness and heat of the girls' throbbing assholes. Their humping slowed, their cocks slipped out, and Marilyn and Nada let out moans that sounded more like moans of frustration than relief.
"They ain't had enough yet," Todd said, watching his jism trickle out of Marilyn's partially open asshole. "What're we gonna do with these nymphos, Myers? They're a coupla fucking bitches in heat, a coupla dogs, for Christsake!"
Bobby got up. Nada's half-open asshole looked so good to him dribbling his freshly shot cum that he couldn't resist sticking the big toe of his right foot up it.
"I'll give this one a toe-fuck up the asshole," Bobby said, squeezing his half-hard cock.
Nada panted as Bobby's toe twisted.
"A toe ain't big enough to satisfy that bitch," Todd said. "Hell, a cock ain't big enough to satisfy that one, nor this one neither." He rammed a finger up Marilyn's asshole and watched his cum froth out around the pumping digit.
"My toe's bigger than your finger," Bobby said.
"My fist is bigger than your toe," Todd said.
"You're crazy," Bobby said. "Your fist!"
