An approach to a more romantic tale.
*
Marco lays on the sofa ready to watch their summer nightly, scary movie. Erica, his younger sister lies between his legs with her back pressed against his chest. It is nothing unusual, but Marco always enjoys the warmth of her body. She wears a loose nightshirt and it slides higher on her thigh, revealing her long tanned legs. He slides his hand between the back of the sofa and the side of her body to place his hand on her covered thigh.
It is nothing for him to touch her this way. She is only two years younger than him and he has always found her attractive as he does their older sister. At twenty-two, his thoughts are raging and the thought of his sister, is always on his mind. So when they sat down to watch movies, he would always make small, but noticeable gestures, hoping that one day Erica may want to act on them. So far it hasn't happened.
They continue watching the movie. Each time she jumps because of what she is seeing on the screen, her shirt reveals more and more of her leg until finally the tip of his fingers touch her smooth thigh. She trembles at the touch, but does not say anything about it and like every night since summer began, he did not remove his hand.
As she keeps on jumping from time to time, her ass is pressing on his hard cock and it is quite pleasurable to feel. Marco places his hand on her stomach and laughs. "You're safe, sis."
Erica smiles and keeps watching the movie. Half way through the movie, Marco dares to place his hand fully on her thigh and slowly caress it, slowly moving closer to the inner side of her thigh. He continues to watch the television and act as if he really is into the movie. Erica doesn't say anything and it feels good to caress her smooth thigh only inches from her crotch.
He tries to look over a shoulder to see if her thong is visible, but he can't see anything. So he keeps going until his hand is almost touching her crotch. Erica isn't jumping nearly as much as before and is still looking at the screen. With his hand on her stomach, Marco can feel her breathing deepen.
Marco's cock is so hard by now that it is becoming painful. He is torn between the idea of going to the bathroom and releasing the pressure with his hand and the idea of continuing what is already doing.
He decides to not masturbate and continue with his caresses. His other hand now slips up from her stomach to just under her breasts. When Erica jumps because of a scary scene, his hand directly slips to cover her crotch. She breathes in sharply and he doesn't move, yet he can fell her silky thong and the outline of her pussy lips on his fingers. Erica can't ignore the fact where his hand is now at, but she still doesn't say anything.
As his hand covers her crotch, he can feel the warmth of her body and his cock twitches with excitement. He wants to stop there, but he just can't. The temptation is too great and he slowly caresses her covered crotch. Erica is breathing deeply and sharply as he manages to slide his finger under the edge of her thong, placing his hand directly between her pussy lips. She is very wet and warm.
He moves his finger slowly from her entrance to her clit and she twitches each time he presses on it which hardens under his touch. As his other hand slips back down to caress her stomach, he slowly inserts a finger into her pussy, just as the movie finishes. Her body tenses immediately, her legs close trapping his hand between her thigh and she sighs heavily. Marco doesn't move, except for his finger which moves around in her pussy lips.
"Mmmm," his sister moans.
Marco slides his right hand to her thighs and pulls her legs to spread them and she does not resist as he inserts two fingers deeper. His right hand moves back up to her breasts, sliding under her nightshirt.
"Uuhh," she sighs.
He keeps sliding his fingers in and out as he twists her nipple between his fingers.
