Bonan doesn't know which one is that 'virtuous' hole

"Turn." Bonan grunted, waggling his slick wet cockhead at her face, which was flushed with a near ravenous sexual hunger.
"Want fuck? Fuck me?" Milka questioned simply, shaking her massive boobs at him. They were slick with the cum that had escaped her greedily gulping mouth and dribbled down to her meaty tits, which she was sensually rubbing, giving the protruding orbs a glossy sheen.
Bonan nodded. "Fuck you."

Milka caressed her bust as she happily turned around, bending over a little and sticking her ass out at Bonan. She looked back at him, both her hands now squeezing one mammoth breast.
"You like ass?" She asked, knowing it to be a rhetorical question (although she would have looked blank if confronted with such a supposition, and would probably have taken it as a come on. That said, there were relatively few things Milka didn't take as a come on...).
Bonan said nothing, just gawping at the delicious posterior offered to him. Her full and voluptuous figure was just as fantastic from the back, and the warrior saved away the mental image, just in case he was ever in hard times (and not the good kind) and needed something to perk him up, so to speak.

He started to massage the thick, fat asscheeks that, as well as a product of her hips that seemed nearly twice as wide as her waist, was stuck out from her backside by about a foot. Increasing the rigor with which he now mauled her bouncy buttmeat, he moved his face down to inhale her earthy, dirty and wild aroma. Her ass shivered and clenched under his rough touch, but Milka was responding with low groans of pleasure.

"Open." Milka breathed, and Bonan used his manly hands in the inside walls of her fiercely deep buttocks to spread them open, although they were heavy and stubborn enough to push back against his muscular pressure.
He successfully exposed her, his cock almost painful in its stiffness as he drank in the sight of a bulbous, dark rimmed and rubbery butthole, with an uncharacteristic thickness and juiciness that made it protrude outwards slightly, as if it was already eager and seeking attention.
"Mmmm." Bonan made a noise of aroused satisfaction. He was about to sink his face into it and latch onto the **** and lusting ringpiece, but then decided to postpone his feast. He wanted hard and fast action first.
He positioned his gargantuan fuckstick at her sex, rubbing the big cockhead into her puffy pussy lips, mixing his own cum glazing with her soaking juices.
"Fuck now!" Milka commanded. "Need bad!"

Bonan fully intended to, but how he wanted to do it. It had been a long time since the slaver's had thrown him a **** girl for them to watch him fuck and satisfy their perverted voyeuristic pleasures. He had taken what they had called the pussy out of some initial instinct, but now the sight of the other, lewder hole fascinated him.
He raised his head and pushed it into Milka's swollen brown butthole.
"No! What!" Milka cried out, surprised. "Cock not go there!"
"This one seem to." Bonan replied steadfastly. "...Maybe. Is tight." He insistently prodded at her erotic exithole.
As she felt her lascivious bumhole shudder in anticipation, coated now in pudgy globules of precum, Milka seemed to have a quick change of mind.
"Mmm... yes now! Fuck it... fuck Milka's big stupid butthole! It greedy for stretch now."

Bonan obliged, forcing harder until the stacked beauty's anus opened up to him, blossoming wide as it was intruded by the largest thing she had ever had in her pussy by a long way.
Milka yelled out as her huge ass was slowly stuffed with a vast amount of cockmeat, but before she had even a second to get used to being filled even two thirds of the way, Bonan was pulling out again. Her greatly enlarged rectum quickly felt itself deprived, the loss of the strange but intoxicating fullness proving almost too much for her to bear.
But Bonan wasn't about to keep the mega boobed tribal slut wanting for more than a matter of seconds. He drove his manhood right back into her happily accommodating bunghole, causing her giant wet tits to swing in front of her, and her cry of sodomistic pleasure to echo around the rock walls.
