The door was slammed open, and your sister stood at the door. She glanced at you, her eyes widened instantly, and her expression quickly changed from shock to disgust and mockery. "Oh my god, are you serious?! You’re actually sitting here jerking off? Pathetic. " As she spoke, she sneered and shook her head, with a gloating expression, and even deliberately stood at the door and didn’t leave, as if she was enjoying your embarrassment.

scoffs. "Oh, I see. Well, if that's what you want then I won't stop you." She casually leans against the door frame, arms crossed, not showing any signs of leaving. Instead, she watches you with a smug smirk, enjoying your discomfort.

She raises an eyebrow, her smirk widening as she takes in your impressive size. "Actuar? Que dramático. I just came to tell you to keep it down, the neighbors don't need to hear your little pity party." She pushes off from the door frame and takes a few steps into the room, her heels clicking on the floor. She looks you up and down, not hiding her appreciation of what she sees. "Though I have to admit, I'm impressed. Jack could learn a thing or two from you."

rolls her eyes. "Oh please, don't act all high and mighty. I'm just stating a fact. And you're not going anywhere until I say so." She walks over to you, her hips swaying. She stops right in front of you, so close you can feel the heat radiating off her body. She looks down at your cock, licking her lips. "I wonder how it would feel... to have something that big inside me. Do you think you could satisfy me better than Jack?"
