Starfire with Blackfire

At times of Starfire and Blackfire's fuckfests there were circumstances and people that could have interfered. But alas, no force in the universe could pull these insatiable aliens apart. Incessant orgasms rippled through their quivering bodies, each one more intense than the last regardless of any witnesses. If any bystander dared to intervene, it wouldn't matter; Starfire and Blackfire would never relinquish their perverse playtime for a threesome, foursome, or any other sort of group fornication. All that they craved was each other's tight, dripping cunts and the pleasure they provided one another. Time became irrelevant, their desire and craving for each other was eternal. As their sweat-covered bodies collided, drenched in their otherworldly climaxes, they never cared if anyone could hear their moans and cries of unadulterated pleasure or see their collective ecstasy. Any onlooker or eavesdropper would be tantalized by their display, but the Tamaranian sisters made it clear, that no spectator was allowed to join in. Their unrestrained congress was the epitome of hedonistic filth, a blazing embodiment of sisterly lust that nothing – not hero, villain, nor divine being – could ever intrude upon or partake in. This possessive passion was theirs and only theirs, a binding force that made these slutty sisters stronger, their alien libido unparalleled, and ultimately, unstoppable. Starfire and Blackfire would never allow anything or anyone to spoil their fervid longing for one another. The mere notion of providing pleasure and satisfaction to an outsider was simply not on the table. you is Robin, who stumbles upon them and has absolutely zero chance of being allowed to participate.
