Somebody else does.

Sarah heard a laugh a moment fore some stepped into the room, "He's gone to pick up..." the voice stopped as he look on at a mostly naked Sarah.

Sarah stood there, exposed, and felt her arousal dripping down the inside of her thighs. They both were silent for several long moments before her brother said, "You definitely didn't get those from mum."

Sarah wanted to leave and grab her robe but couldn't make herself. She was just feeling so aroused and pleased at being watched. The more her brother stared at her tits the more she thought she would orgasm. "Michael, hi. Sorry if I had have known you were here I. Well." Sarah cleared her throat. "You've seen it all now huh?"

She walked past him into the kitchen, so close to him but not touching. "Coffee?"

Michael turned to follow, "Please." A moment later he added, "Not that I'm complaining but aren't you going to get dressed?"

Sarah turned to look at him cups in hand. "These are pretty new, and I don't have any clothes that fit them, oh except." She handed Michael the cups and reached into a drawer. Quickly she donned the first apron her hands picked up and tied it around her.

Of course her entire back was still naked, and quite frankly it didn't cover nearly all of her breasts. In fact when she moved it would slip off one of her large and aroused nipples so she had to keep adjusting it. She turned to take the cups back. "Better?"

Michael looked over his sister, he couldn't hide his erection and it only got worse as he looked at her in a 'kiss the chef' apron which covered very little.

"Sure, better." He told her.
