*Katie and Hayley lean forward, their hot breath tickling the sensitive skin of Sully's neck as they continue to stroke him. They can feel his body tensing beneath their hands, feel his excitement building with each passing second. As he begins to lose control, they speed up, their fingers pressing deep into his flesh, milking every last drop of pleasure from him. "Cum for us," Katie whispers, her words hot against his ear. "Show us what a good little slut you are." As if on cue, he groans loudly, his hips bucking violently in their grasp as he releases himself over their hands and onto the floor between them. His seed spurts out in thick, hot streams, covering their palms and wrists. They squeeze harder, milking him until there's nothing left but tiny twitches and soft gasps. Finally, they let go, their hands slipping away from his spent cock. He collapses bonelessly against them, panting heavily as he tries to catch his breath.

Rob, still fucking Christina hard, glances over and sees the mess they've made of Sully/Ashley. A wicked grin spreads across his face. "Looks like someone needs a cleanup," he says, pulling out and stepping off the couch. With long strides, he approaches them, his cock already half-hard again. "Why don't you help your sister?" he suggests, nodding toward where Christina lies, her legs spread wide, her sex glistening with sweat and cum.

Katie and Hayley watch with bated breath as Sully licks and cleans Christina, making sure every drop of cum is gone. They can feel their own arousal building again just from watching their brother in action, knowing that he's touching another man's discarded love juices. Their hands slip unnoticed between Christina's legs, rubbing circles around her clit, teasing it mercilessly. "You know what would be even better?" Hayley whispers, leaning in close to Christina's ear. "If you could taste some of his cum on my fingers." She slowly slides one finger into Christina's mouth, watching as she sucks greedily at the digit, desperate for any taste of him. Katie smirks, pulling her other fingers away from where they'd been idly playing with Sully's now-soft cock. With a wicked grin, she presses them against his lips, forcing his mouth open before pushing them inside. "Suck on those," she says simply, her voice low and husky. "Taste your own cum." As Sully obeys, his tongue swirls around Katie's fingers, lapping up the salty mix of their combined essence. It doesn't take long for his cock to start stirring again beneath his sister's hand. Rob watches approvingly, a satisfied smile curling his lips.

Katie smirks, seeming to sense your relief. "Well, that's good to hear... For now." She leans in close, her voice taking on a flirtatious tone. "But we do have some bigger plans in store for you, sis~"

Hayley chuckles darkly, nodding in agreement. "Yeah, you haven't seen anything yet. And trust me, once we really get started, those clothes won't be the only things changing..."

They both giggle evilly, leaving you wondering just what kind of "bigger plans"

Hayley grins wickedly. "Oh, Trev, don't be such a stick-in-the-mud! It'll be so much fun, I promise." She hooks her arm through yours, leading you back inside. "Now, let's go relax and get ready for dinner. We can watch a movie or something."

Katie skips along beside you, rubbing your shoulders playfully. "Yeah, and maybe while we're watching, we could use some of these..."

Hayley's breath hitches as she feels you come in your cage, her entire body tensing at the sensation. Her grip on your hair tightens even further, her head falling back against the wall in ecstasy. She looks down at Katie, a predatory grin spreading across her lips as she sees the desire in her sister's eyes. "Why don't you come closer, sweetie," she pants, "and see if we can't help you find some relief?"

Hayley's eyes meet Katie's as she moves aside, making room for her sister to join them against the door. "You can use your hands," she whispers, arching her back slightly to offer more access to her now-sensitive body.

Katie hesitates only a moment before obeying, reaching out tentatively to touch Hayley where you had been just moments ago. Her fingers tremble as they brush against Hayley's swollen clit, and she lets out a soft moan of pleasure.

Are you kidding? Our goal is to completely feminize you, sis.

You were supposed to be a sister all along, remember? Now you're just going to have some extra fun parts and stuff.
