I probed yours, you’ll probe mine

Releasing Zulu’s cock from the confines of her mouth, Thyra smiled and turned around, placing her hands on the bed and wiggling her ass invitingly to Zulu.
Looking back over her shoulder, she gave him a wicked smile and said:
“Well, I probed yours, so why don’t you probe mine handsome?”
Zulu just couldn’t believe it, this girl that he didn’t even know had just sucked off him, after having done the same to his brother, and now she was offering him to fuck her ass.
Boris had seated himself by the kitchen table in the small cot, watching in anticipation and drinking some ale as his brother approached towards Thyra’s waiting anus.
As he placed the head of his cock at the entrance to her rectum, Zulu closed his eyes and then slowly pushed forwards, his hands holding on to her hips.
Despite her ass being incredibly tight and not having been lubricated, Zulu’s impressively sized member was able to penetrate it, although with some difficulty at first.
Thyra was screaming loudly for every inch that Zulu advanced up her rectum, but between her screams kept urging him to push on, which he gladly did.
While doing so, he noticed that the penetration went smother for each second, as though Thyra’s rectum was lubricating itself to ease his taking of her anus.
Soon thereafter, he looked down to find that his cock was placed as far up Thyra’s ass as possible, and decided to pick up pace considerably, his right foot resting on the bed to add some **** to his thrusts forwards.
Thyra couldn’t believe how good it felt to be so sodomized in such an intense manner, feeling Zulu’s hips slam against her buttocks with intervals of less than a second.
Then, with one last savage thrust, Zulu came as far inside of her that he could push and a flood of his cum gushed into her rectum, white semen trailing down her thighs.
Watching his brother take that girl in the butt, and having finished his ale, Boris felt a desire to get back into the game.
