Who says siblings can't get along

Glancing up at him, Ellen felt distracted for a second by the raw image of his bulbous mushroom cock head and fleshy giant balls. Urgh! Why does he always do this? Doesn't he feel even a little ashamed making everything so... obvious. I mean, if people have **** in the matter then that's okay, but to be this blatant...

"Do you mind not having your..THING right in my face please?" Resisting the urge to slap that thing away and recoil, she looked up at her brother's smiling face with a pleading expression.

"Ohh, my bad sis. You know how it is, fog brain in the morning and all. Forgive me?" Edging back and sitting on the couch, Tim did this to reassure her that he didn't mean anything about his prior faux par. Just to make doubly sure, he cupped his hands together and covered the sight of his junk to the best of his ability.

Sporting a pouting expression his sister sat up and glared at him. " You just love teasing me huh? How many times has mom told you to leave me alone? Just so you know, I'm only forgiving you easily because I'm almost finished here and have other things on. If it wasn't for that...".

"Sure... Sure...," Lifting his hands up in surrender Tim gave way to his sister much too easily, not that she had noticed though. She didn't even catch the way his eyes ran over her body covertly.

Relaxing her stance on her modesty, she soon uncovered the parts she had wanted hidden. A sunny smile etched itself on her face as she thought about her upcoming trip to the mall with her friend later today. Even the sight of her brothers penis growing didn't stifle her mood anymore. It was amazing how easily men were aroused at anything that had tits or asses, even when it involved family members. Guess all these morning workouts didn't hurt too.

"Timmmmmm..... " Pouncing onto his lap and clutching his thighs, his sister pleaded with him in a sing song voice. Where on earth did that timid and shy sister of his go? It was as if a switch was flipped.

Seeing where his sister's hands were moving Tim didn't know how to act. It took all his calm not to trap his sister's hands and mouth to pleasure himself with. Plus on the side of caution, he wasn't sure how she would react yet if he really did attempt something.

"W-What!?!.." A explosive yell fueled in anger and lust drew his sister's pleas to a stop. Her hands stopped, then moved off his thighs, easing his rapidly beating heart.

"No need to shout... All I wanted was for you to help me. It's the last move Downward Dog. All I need from you is to hold my hips when I go down." Noticing his dubious stare she felt the need to explain while emphasizing her hips. "It's just...it's been a bit sore around my mid section lately and I don't want to worsen it. So.. will you help? If you can't, forget it."
