Ellen his sister

Making his way downstairs felt kind of weird, it was not something he was used to. Not having underwear keeping things in check made his nudity more apparent.

As he got to the living room that separated the upstairs landing from the kitchen, Tim heard the TV playing. Looking over there seemed to be one of those breakfast aerobics classes on. But what was strange about it was the entire cast was naked.

Seeing the sweaty vixens moving and posing in positions that would make a centerfold blush, that devilish smile returned.

"Mmm... Very good..."

"Who's there!?.."

A girly shout sounded from the the couch that was blocking the lower half of his view, moving forward, he found the source.

"E-llen?" Tim felt the words in his mouth grow dry.

"Oh... It's just you Tim..." A relieved whisper came from his sister at realising who it was, she patted her beating heart with her hand.

Tim couldn't believe how his sister had filled out... He knew he wrote for this to happen, but seeing is truely believing. Where had that tomboyish, freckled raven haired girl gone to? If it wasn't for the familiar facial features and eyes he would've sworn that this was a completely different person. By god, just look at how her hair fountains down her back to rest on her pert ass, just daring his eyes to linger there. Even her C cup breasts had an ascetic appeal to them, like fleshy tarts with a cherry on top ready to plucked. But sadly, her legs seemed crossed over, likely from being startled mid-form while excersing. Ironically, this fact made his blood boil the most.

"Uh..hello? Mind not staring so much?" Waving her free hand about to get his attention, his sister felt his gaze becoming invasive. She shielded her breasts with the hand that was originally on her solar plexus.

"Haha, me? You've got to be joking sis. I was checking if you were doing your morning excersises correct. Looks about right..." Cracking a smug smile Tim walked comfortably around the sofa to stand over his sister. This made his sister have to peer up past his massive balls and cock.
