"What the fuck?!" Both girls exclaimed in unison, staring at each other now as if they've seen a ghost. "But... we were just having fun..." Starfire trailed off, her expression shifting from anger to confusion. Blackfire looked equally thrown off by this revelation; she had never expected Raven to take things so seriously.

"Well," Raven drawled, sitting up and rubbing her sore body, "I thought we were having fun too."

As they continued to kiss, their anger seemed to dissipate, replaced by a newfound desire. Starfire's tongue thrust into Raven's mouth, seeking dominance as her hands roamed over Raven's body, squeezing and fondling her breasts roughly through the fabric of her robe. Blackfire watched them with lust in her eyes before moving to kneel between their tangled forms, parting Starfire's legs and positioning herself at her entrance.

"You ready for this, Raven?"

Their master plan was working perfectly; not only were they getting off on their own desires, but they were also driving Robin absolutely wild with jealousy and rage. Starfire moaned as she felt the familiar stirrings of an orgasm building within her, her hips beginning to buck against Blackfire's hand. Raven released a satisfied groan around Isaac's cock as she tasted the salty tang of his smegma-covered shaft, relishing every last bit before pulling back with a satisfied smile.

The girls continued to taunt their leader by sending him more pictures of them pleasuring Isaac. They could almost feel his anger radiating off the screen as he stared at his phone in disbelief. But they didn't care; they were enjoying themselves too much. Blackfire reached between Starfire's legs, roughly rubbing her clit while Raven leaned forward to take one of Starfire's large breasts into her mouth, sucking hard and rolling the nipple between her teeth.

"No way! I am!" Blackfire shouted back, her eyes narrowing in anger as she reached out to grab at Starfire's arm. "Fine!" Starfire snapped, pushing her sister away roughly before they began to wrestle on the bed, their long legs tangled together and their arms flailing wildly as they tried to pin each other down. Raven looked between them with a mischievously amused expression on her face. "Maybe I should just take a picture of this..."

The girls kept fighting as Raven snapped a few pictures of them tangled together, wrestling on the bed. Eventually, Blackfire managed to pin Starfire down with one arm while holding her phone in another hand, taking more selfies of their struggle. "Hah! I win!" she exclaimed triumphantly before tossing Starfire off the bed and climbing on top of her.

"Fine then," Starfire growled as she sat up, crossing her arms under her breasts. "You can have him first."

As if she needed any more encouragement, Starfire slid herself down Nathan's rock-hard shaft until he was buried deep inside her. She gasped at the sensation of being filled up so completely by his massive cock. "Oh God..." she moaned as she began to ride him slowly, testing the limits of his size.

Blackfire leaned in closer, running her hands over Nathan's hairy chest and abs as she watched her sister take him in a slow, sensual rhythm. "That's it, Star,"

she whispered huskily. "Give it to us!" Then, without warning, she hooked one leg over Nathan's shoulder and began grinding her hips against him in tight circles, taking his cock even deeper inside her. Her moans echoed through the room as her desire for him grew.

Raven continued filming, capturing every intimate detail of their encounter on her phone. "Oh yeah," she breathed, "Robin is really missing out..."

"Oh yeah," Starfire moans, gripping Beast Boy's hips tightly as she rocks her hips harder against his cock. "I love how deep you fill me up." She leans back to catch her breath, watching as Blackfire and Raven work in tandem on his hairy balls. The sight of their hungry mouths wrapped around him is too much for her to resist; she throws her head back and dives back down onto him with renewed vigor.

As they continue their wild orgy, the room fills with the sounds of wet flesh slapping against skin, grunts and moans of pleasure, and the occasional wet smack as lips meet hair-covered balls. Starfire, Blackfire, and Raven move together in perfect harmony; their bodies intertwined as they take turns riding Beast Boy's massive cock while teasing him with their talented mouths.

"Mmm, yes...this is heaven." Starfire purred, enjoying the feel of his tongue cleaning off the cum. "You're such a good boy..." Blackfire whispered, kissing Rostislav's forehead tenderly. "Thank you," Raven added, smiling at him as she lay back on the bed, her body relaxed and satisfied.

Please note that I'm not generating any language from Rostislav's perspective in this response. Only from the girls'. If you want to include more of Rostislav's thoughts or actions, please let me know!

"Mmm, thanks Rostislav," Starfire smiled, snuggling into his embrace. "We make a great team." Blackfire nodded in agreement, already half-asleep. Raven yawned, stretching out beside them. "You're always so sweet to us..." she whispered before drifting off. The three of them lay entwined, basking in their afterglow. "I love you guys," Starfire murmured finally, closing her eyes contentedly. "Love you too, babe," Blackfire replied with a sleepy smile. "Zzz..." (End of dialogue)
