Yara and I were eager to push our lucky friend Cosmo further into depravity. As he stood helplessly before us, bound and vulnerable, we knew exactly what we wanted to do with him. First, we attached him upside down to a pulley with his hands tied behind his back, making sure he was completely at our mercy.
"Now, Cosmo," Yara purred, running her fingers down his chest, "you have a special task ahead of you." She kicked off her high heels, revealing her perfect feet to him. "You must worship my feet before you can earn any other reward."
Cosmo grew even more aroused as he watched Yara's toes wiggle invitingly, his cock throbbing for release. With trembling hands, he leaned forward and began to lick the sweaty soles of her feet clean. The taste of her skin sent shivers down his spine, and he obeyed her every command without hesitation.
Once he had finished worshipping Yara's feet, it was my turn. I strutted in front of him, my own high heels clicking delicately against the floor. "Time to pay attention to my asshole, Cosmo," I growled, grinding my hips into his face. "You're going to clean it thoroughly with your tongue."
As he began lapping at my tight anus, I pulled on his balls, making him moan in pleasure-pain. It felt incredible having him completely under my control, and I could tell that Yara felt the same way. We continued torturing him with our bodies, moving back and forth over his face until we were both satisfied that he had cleaned us thoroughly enough.
Next, we connected Cosmo to what looked like a milking machine, adjusting its settings until he was as horny and aching as possible without allowing him to cum. Then Yara squatted over him, allowing her juicy ass to slide down onto his face. "You're going to taste every inch of me, Cosmo," she purred, grinding her hips against his nose.
As she began pushing her warm, soft, slightly sticky ass into his mouth, I could hear him moaning in delight. But we weren't done with him yet. We both knew that the ultimate test of his obedience would be when we made him swallow Yara's shit.
"Open wide, Cosmo," Yara said, her voice full of dark promise. And so he did, his eyes closed in concentration as he tried not to gag on the unexpected taste and texture. We watched in morbid fascination as he swallows every drop of Yara's feces, cleaning it from her ass with his own tongue before finally gulping it down.
Finally satisfied that Cosmo had passed our test of submission, we detached him from the milking machine and allowed him to cum. As he came all over himself, we continued to torment him further by forcing him to swallow his own sperm. And when he was spent, we pushed him even further by having him vomit up Yara's shit before smearing the brown puke back into his mouth again.
Looking at him now, covered in our filth but excited beyond words, we knew that we had truly claimed him as ours. It was a wild ride, one that we would certainly remember for a long time to come. And who knows what other perversions we might introduce to our dearest friend Cosmo next? The possibilities were endless, and we couldn't wait to explore them together.
