Katie whispers huskily as she grinds her hips against your ass, feeling your body respond eagerly to her touch. The anticipation of going shopping for new clothes with them only heightens the sensations coursing through you. "Maybe we can find something special just for my little sister," Katie teases, knowing full well that this is exactly what you want: their attention and affection.

The three of you make your way through the mall, Hayley and Katie leading the way as they search for clothes that would fit their new feminine sibling. Every now and then, one of them would turn to you with a suggestive smile or a teasing comment, making sure not to forget about how horny and needy you are.

Their grins widen as they pull you into their room, slamming the door behind them "Now, let's start with these clothes," Hayley says, grabbing a bag full of dresses and skirts from her closet. Katie nods excitedly, already reaching for a pair of panties and a bra from hers. "We'll have you looking like one of us in no time."

"Now relax sweetie, just listen to my voice... You're feeling so relaxed, so calm..." Hayley whispers softly "Yes, yes, you want to be our sister... You want to look beautiful for us..." Katie adds, stroking your hair gently "Just imagine yourself wearing pretty dresses and makeup... Feeling like a real girl..." The sisters chant in unison, their voices lulling you deeper into trance. "You are becoming more feminine by the second..."

Hayley giggles as she watches Katie help you change into the new undergarments. Once you're finished, she walks over and inspects your work. "Not bad, Katie. You have a knack for this sort of thing." She then turns to you with a mischievous glint in her eye. "Now, Logan... I mean, Hayley... it's time for some makeup!" She hands you a makeup bag and motions for you to sit down on the bed. "

Hayley begins to carefully apply foundation, powder, blush, eye shadow, and mascara onto your face. As she works, Katie stands behind you, admiring the transformation in the mirror. "You're looking really good already," she whispers into your ear. "But I think we could use some lipstick... just to finish it off." She reaches around you and squeezes a generous amount of bright red lipstick onto her fingers before rubbing them together.

Katie giggles and nudges you with her hip. "You know we'll take good care of you, right? We're just excited to have another girl in the family." Hayley beams proudly as she sits down beside you on the couch. "And who knows, maybe one day we can all go shopping for clothes together! Wouldn't that be fun?"

Their eyes sparkle with excitement at the thought of continuing their feminization journey with you.

Hayley and Katie exchange knowing glances before turning back to you, their expressions full of anticipation. "So," Hayley begins, her voice soft and teasing, "are you ready for our next lesson? We've got lots of fun things planned!" Katie nods eagerly, already imagining the ways she can help mold her new sister into the perfect feminine specimen.

With Hayley's help, you strip out of your clothes, revealing your naked body to the sisters. They both giggle and lewdly appraise your assets as they decide what you'll wear first. Katie pulls out a lacy bra from her sister's stash in your closet and hands it to Hayley. "Here, put this on him."

Hayley giggles at your reaction and cups your new breasts in her hands, teasing them a bit before putting the bra on you. "Don't worry, they're just practice. You'll get used to it," she says, fastening the hooks behind your back. As for your penis... well, that's going away soon enough.

Hayley grins and nods in agreement, her fingers dancing across your chest as she imagines the look on their parents' faces when they tell them about their new daughter. "We'll just have to make sure we practice our story together first," she says with a wink. "After all, we don't want to leave anything out."

As you lie there, cuddled between the two of them, you can't help but feel an overwhelming sense of belonging and love washing over you.

"Of course we will," Katie says with a soft smile, brushing her fingers through your hair again. "We'll make sure they understand just how perfect our new family is." As she speaks, she leans in closer to you, pressing her body against yours and nuzzling her face into your neck. You can feel the warmth of her breath on your skin, sending shivers down your spine.
