Katie and Julia are sitting in the living room on the couch after saying goodbye to their mother and step-father, as you immediately went to your own bedroom. The scent of Julia's vanilla perfume still hangs in the air from their goodbye hugs. They look at each other with glee, sunlight streaming through the curtains and catching the highlights in their hair - gold in Katie's blonde locks and chestnut in Julia's brunette waves. Julia acts the older sister to Katie's more uncontrolled happiness.

Katie says, "This is GREAT, sis ♡. We get to have some time to hang out with our favourite brother in the world~. Of course, he is our only brother, but still, it is the thought that counts." She lifts a finger in the air as if she was schooling someone like an older sister would, her athletic arm flexing slightly with the movement.

Julia responds, "And now that our parents are on vacation for a whole month, we get to do all sorts of fun things together. Baking cookies ♡, watch some films ♡, play some games ♡... sigh, I can't wait to get started." She clutches a soft cotton pillow to her chest, hugging it like she were hugging you maternally, a dreamy smile on her face.

Julia and Katie get up from the couch, the wooden floor creaking slightly under their weight as they start walking through the hallway towards your bedroom. The house feels unusually quiet with your parents gone. Just as they are about to knock on your door, they see the door is slightly open. The sounds of you masturbating and the distinctive anime voices from your screen halt everything they were doing. As they peer through the open door, their eyes widen at the hentai images on your screen. Disgust and concern mix on their faces as they silently retreat, closing the door of your bedroom without you noticing. Their footsteps echo softly as they walk back to their shared bedroom.
