Chapter 4: Deeper and Harder
"You two are very, very bad girls."
He then kissed both his daughters slowly and deeply.
With Sara due back from her book club sooner, rather than later, the incestuous trio didn't have much time to come down from their sexually charged high. Rachel and Trisha lay on the bed together and watched contently as their father dressed; evidence of his cock's huge eruption splattered randomly on the creamy, tanned skin of the girls' torsos and thighs.
As Dan finished dressing, Trisha sprung up off the bed and stood between him and the doorway.
"So, Dad, is that all you've got in the tank? Or are you planning on giving Mom some of this tonight." The brunette began to gently stroke her father's flaccid cock beneath his pants as she ended her sentence.
Rachel giggled as she watched Trisha working their father. Dan closed his eyes and took a deep breath as his younger daughter's petite hand caressed his tired prick teasingly. He then opened them again and with noticeable effort, took Trisha's hands and held them down by her side.
"When we have a little more time, I'll show you just how much I have in my tank, honey."
His loving expression belied the intense tone of his avowal.
"And that goes for you, too." He added as he turned his head to Rachel.
The blonde felt a surge of lusty anticipation flood her system as her father locked eyes with her. The look he gave left her no doubt that given the chance he would indeed show them just how far he could go.
"Is that a promise?" the younger girl asked suggestively, her hands still being held fast by her father.
Dan answered only with a fatigued smile and a deliberate kiss on Trisha's forehead before leaving his daughter's room.
The sisters cleaned themselves up and went to their respective rooms to get dressed shortly after.
Rachel watched herself in the mirror as she dressed slowly. It seemed hard for her to believe that only three weeks had passed since this all began. It felt like years; almost like this was the way things had always been ... or should have been.
Just a few minutes later though, Rachel found herself dealing with her first feelings of remorse. She thought she had examined the situation from every possible angle before the seduction of her father; but she had missed something, a glaring something at that. Her father had been unfaithful to her mother, and she and Trisha were the cause.
Sara came home only minutes after the girls had finished dressing. Rachel found it impossible to look her mom in the eyes and almost as hard to hide her guilty feelings. Although she knew she was just being paranoid, she felt that Sara could see evidence of the forbidden deed all over her face. Before long, she had retreated to the relative sanctuary of her room, where she stayed for the rest of the night.
At 11:30 the beautiful blonde was laying in bed quietly staring into the darkness, unable to sleep as she grappled with her conflicted emotions. She heard her door open and propped herself up on her elbows to see Trisha slip silently into the room. By the pale moonlight bleeding through her window, Rachel could see her sister was wearing nothing but a pair of white cotton panties.
Trisha slid alongside her older sister on the bed and began to kiss the blonde deeply as her left hand found one of Rachel's firm breasts. After a long kiss, Trisha pulled back with a slightly puzzled look.
"Is something wrong?" the brunette asked as she idly continued manipulating her sister's breast softly.
After a brief pause Rachel answered.
"It's just that ... well ... I feel like shit that we made Dad cheat on Mom."
Trisha stared blankly at her sister for a long moment before suddenly breaking into a muffled laugh.
"Rachel, first of all we didn't make Dad do anything. He wanted that for a long time. Believe me. And I don't think she minds the results so much anyway ... can't you hear that?"
Rachel stared, a little confused, at Trisha and after a moment she did hear something. It was moaning. And it was coming through the wall from their parents' room. Just as she realized what the sound was, Trisha nodded deliberately to confirm it.
"Have you ever heard them through your wall before?" the younger girl asked, as if she already knew the answer.
Rachel shook her head slowly.
"So why do you think that tonight, of all nights, Mom would be moaning louder than ever before?" The brunette's hand slipped down like a snake between Rachel's legs as she continued. "You know if you still feel bad, you just might get a chance to make it up to her."
Rachel whimpered as Trisha began to stroke her pussy gently.
"Would you like that?"
The blonde's body began to respond involuntarily to her sister's delicate ministrations as she answered her question with an affirmative nod.
"Would you like to slip down, between her legs ..." Trisha increased her pace and Rachel's breathing quickened accordingly. "And bring your mouth to her hot, wet pussy..."
"Yessssss." Rachel hissed as her younger sister moved down between her legs.
"Say it! Tell me what you want to do!"
Rachel moaned out as Trisha penetrated her with two fingers and began to tongue her clit.
"I want to eat her pussy!" she managed to spit out between breathy moans.
"Who's pussy?" the younger girl asked immediately with an edge.
"I want to eat Mom's pussy!"
Trisha hesitated for a second before continuing her passionate tonguing of her sister's pussy. Rachel's proclamation had been much louder than she had expected and if their parents hadn't been busy with their own noisemaking, she was sure they would have heard it. However, their mother's faint moans could still be heard carrying through the shared wall so it was only a matter of a minute or two until Trisha had Rachel squealing and writhing in orgasmic ecstasy.
The instant that Rachel stopped twitching, Trisha pulled her off the bed as she leaned back against the wall and rested one foot up on the night table. The older girl immediately dropped to her knees and dove into her sister's dripping pussy. The brunette smiled and bit her bottom lip as she turned her ear to the wall and let out a low whimper. She caressed the wall gently as her hips began to sway in reply to Rachel's delicate lapping.
Trisha listened acutely to the growing moans of her mother. She envisioned her father's huge cock blasting away relentlessly at Sara's juicy pussy and tried to imagine exactly what contorted look her beautiful mother was wearing in response. Knowing that they were fucking only a few feet away heightened her arousal and along with Rachel's keen knowledge of just how to eat her pussy, she soon found herself struggling to hold off her certain release.
