The apartment was silent and almost in darkness. Her parents were out and her brother was in his room, probably watching a movie. Becky was bored, may be she'd go see what her brother was watching, if it wasn't too dull she might watch it with him. Or see if she could persuade him to go buy her some beers maybe, yeah that sounded like a good plan, she thought as she left her room.
The nineteen year old crept down the hall; she could hear heavy breathing and a rhythmic shuffling coming from her brother Joseph's bedroom. His door was slightly open and she could see light flickering through it. Quietly she pushed the door open further, she could see the TV, it was showing a guy screwing a big breasted blonde on what looked like a kitchen counter, but that was not what drew her eyes, it was Joe, lying on his bed, naked, his fist moving rapidly up and down his cock as he stared at the porn film.
She could hardly believe her eyes; he was huge, far bigger than any of the boys she'd dated. His cock had to be at least 9 inches long and thick too, with nice strong veins all down its length. As she watched Joe suddenly took in a sharp breath and almost froze, a long jet of cum shooting from his cock to land on his stomach, quickly followed by four more jets, each a little smaller. Joe let out a long sigh and then to Becky's amazement began stroking his cock again, it having not softened at all.
Without thinking about what she was doing, Becky reached inside her own panties, her fingers seeking out the lightly furred furrow between her legs. She was already wet and the questing fingers soon found the hot little button at the top of her pussy. She stared at her brother's body, taking in the strong chest and defined abs but always returning to his cock as if her eyes were on strings. Her left hand was now pinching her nipples on her 36C breasts she didn't even remember uncovering. She was getting close.
"You'd best get in here Beck" Joe suddenly said, very matter of factly. "I can see you in the mirror, and you look pretty damn fine from here!"
Becky gasped, but stumbled forward into her brother's room. He hadn't stopped wanking so neither did she.
"I...I...oh ...ummm" she stammered
"It's ok sis" he smiled "I don't mind, in fact I'm kinda honoured" "Looks like my little sister is all grown up. Very nice" he grinned.
"Joe may I...may I touch it?" she asked
"Sure, touch it, taste it, do what you like"
Needing no second invitation the girl leant forward and wrapped her own hands round her brother's shaft, she began to move them up and down. Joe sat up and placed his hands on her wonderful round tits, squeezing gently at first.
"Oh wow sis, they're so soft." he murmured.
"Harder, squeeze 'em harder." She breathed, at the same time she released her brother's cock with one hand and pushed her panties down to her ankles, then stepped out of them.
Joe reached out and cupped her exposed pussy, then slid two fingers quickly into its pouting folds.
"Oh Bec! You're so fuckin' wet! Wanna taste your big bro's meat" He asked.
Becky didn't reply, she just lowered her head and pushed the engorged helmet of her brother's cock into her mouth. Joe gasped but reached for his sister's legs and ass, pulling her round and on top of him, and then it was Becky's turn to gasp as his tongue pushed into her slick folds. Neither spoke, the sound of licking and sucking filled the room.
