Brenda is Shelly’s 28 year old sister, she is staying with us while she moves to Dallas. Brenda awoke to a strange sound coming through the wall. At first she had no idea what it was. She rolled onto her back and lay in bed for a while, listening. It is already morning and faint rays of light shone threw the curtains. Brenda looked at the clock. It is still early. She breathed quietly, then held her breath, waiting for the sounds to become clearer. Something told her that she had been dimly aware of this noise for since moving in a week ago. Her dreams had been strange, troubling and erotic. The quite outside meant she is able to hear the unfamiliar sound more clearly. With a sudden quiver in her pussy she realized what the noise was. “ Oh yes! Oh yes! Ooh, that’s so good! Ah, right there, yes, yes! Ahh, all the way in, so deep, so deep! Don’t stop! Ride me! Ride me! Ahh god, I’m cumming, ahh!” It was the sound of her sister screaming, accompanied by moans and grunts from me. “ Again! Again! Fuck me harder this time! Do it to me, do it to me, ooh god, right in there!” Brenda’s face and neck flushed hot and she immediately broke out in a sweat. In her soft, cotton pajamas she is suddenly very warm. Her fingers wandered in the direction where she felt warmest. No! Not here. She unbuttoned her top but is still too warm. The noise continued for what seemed like hours. she decided to get up, hoping that might cool her off.

As she passed their bedroom, their groans reached an almost deafening crescendo. As it was too early for breakfast she passed through the kitchen and opened the door to the covered patio. Brenda is grateful for the breeze on her skin. She re-buttoned her top and went to sit in a patio chair. She sighed and wondered how her sister could have such flagrant disregard for decency. Tiredness overcame her and her head drooped. After a while Brenda is jolted from her sleep by the sound of the kitchen door slamming. She opened her eyes and there before her, standing on the lawn, was a stark naked woman: her sister Shelly. With her back to the house, her bare feet planted firmly in the grass, she ran her fingers through her long, blonde hair. She lowered her arms to her belly, then further down. She bent forward and spread her feet slightly wider and Brenda saw her fingertips between her legs, her nails lightly grazing her blonde pubic curls and her labia. Then she turned around. Brenda suddenly realized her mouth was open and, strangely, her top had become unbuttoned again. Her sister’s right arm flew to her breasts and her left to her pubic region. She glanced to the door, then smiled, dropped her arms and shrugged. Brenda kept her eyes locked on hers but it was too late. Brenda’s arousal was obvious to Shelly. She relaxed and strolled over to the bench near her chair. “ I guess you heard everything, huh?” Shelly asked her.

Brenda blushed even harder than ever and looked down. This was so wrong. She should be totally grossed out at the thought of her sister being so sexual. Yet there was a burning sensation between her legs that increased as she imagined them having sex. Brenda clenched her legs together and longed to place her fingers between them. She was so turned on. When her eyes returned to Shelly, Shelly is staring at Brenda intently. Shelly lifted one foot to rest on the bench beside her and Brenda is given a full view of her pussy. Through the soft hair Brenda saw the lips of Shelly’s slit glistening with juice, and possibly also cum. Finally, Brenda managed to tear her eyes away, afraid of where this was going. Shelly clearly found the situation more amusing than Brenda did. Shelly shrugged. “ I suppose we’ve got a little too used to our lifestyle.” It was Shelly’s turn to blush just a little. She cleared her throat quietly and asked, “ So Brenda, is there anyone special in your life yet?” Brenda shook her head, incredibly self-conscious; conscious of her blushing.

John wanted me from the moment he saw me and nothing, certainly not the fact that I’m younger then him, was going to stop us. We have been at it like rabbits from the day we met. “ Shelly!” Brenda protested. “ The first time I seen John’s cock… I was stunned,” she steamed ahead regardless of Brenda’s embarrassment, “ He had to push my face into the pillow, I was making so much noise. I remember the feeling of him entering me for the first time. Oh,” she gasped with her eyes closed, “ it hurt being stretched so wide. I wanted him so much I was so ready to take him, and he’s so big!” She winked at me. “ A girl has to be relaxed to take it, especially the first time. Nerves make you tense and then you can get hurt.” Shelly glanced at Brenda pointedly, crossed her legs, “ Yes, it always hurts the first time. ” Shelly continued, “ So we do it all night, every night.” Shelly laughed quietly. “ He makes me so sore, and I think he is cock sore, but we don’t care. When he gets too tired, which is only after hours and hours of solid sex, he uses his tongue and fingers.” Shelly narrowed her eyes at Brenda and she felt as naked as her. “ He gives me one massive orgasm after another, and then I go down on him.” Brenda clamped her mouth shut tightly, afraid of how she must look. By now she is in a state of shock.

Suddenly Brenda feels Shelly’s soft, warm skin against hers and she realized how much she loved her. Shelly licked Brenda’s ear and whispered hotly, “ Would you like John to fuck you?” Brenda looked at her sister and nodded yes.
Shelly took Brenda’s hand and brought her to our bedroom. Brenda now wanted so desperately to turn around and leave but that is impossible. In finding her voice Brenda now also found the strength to stand there.
