In the morning, Sky slipped out of her parents' bedroom, careful not to disturb her still-sleeping father. Tiptoeing down the carpeted hallway, she found her mother already awake in the kitchen, a restful smile etched on her contented face as she sipped on a hot cup of tea.
"So," Sky began tentatively, "about last night..."
"How was it?" asked her mother, raising a curious eyebrow.
"It was great, Mom, no complaints."
"Really? Your father didn't keep you up all night?
Sky was way too embarrassed to tell her mother what really happened. She decided to keep the sticky details to herself and offered a casual reply.
"He woke me up a couple of times, but nothing I couldn't handle. What about you?"
Jane was relieved to learn that Sky had enjoyed her night with her father. As for herself, she felt absolutely amazing after finally getting a good night's rest and was hopeful they could continue with their new sleeping arrangements. The tension between the two of them was melting away, replaced by a newfound mother-daughter camaraderie.
"I had such a good night's sleep. Thank you darling. You don't know how much I needed that."
Me too, thought Sky, remembering her father's probing fingers, and her amazing orgasm. Surely her mother suspected something...
A thoughtful frown creased Sky's brow. "But what about you, Mom? Are you sure you're okay with..." she trailed off, gesturing towards the bedroom where Frank was still sleeping.
Jane's smile faltered slightly.
"The truth is another good night's sleep would be a dream come true. But I wouldn't want you to be uncomfortable sharing a bed with your father, especially..." she hesitated, searching for the right words, "considering his...quirks."
Sky surprised herself by bursting out laughing. "Actually, Mom, I kind of like it. It's weird, sure, but for some reason, it's comforting that he thinks I'm you while he's sleeping."
Relief washed over Jane. "You really think so? You wouldn't mind doing it again?"
Sky grinned. "Absolutely!"
Jane's eyes twinkled. "Deal."
Later that night, after another dinner filled with laughter and genuine conversation, mother and daughter lay awake in their respective bedrooms waiting for Frank's tell-tale snores to fill the air. Once again, the swop ran as smoothly as a well-oiled machine. The met in the hallway, grinning mischievously in the moonlight, and tiptoed quietly to their designated beds.
This time, Sky had decided to just wear a t-shirt with no panties, hoping her father would play with her pussy again. But to her surprise nothing happened. Frank just lay there, snoring. She tried rubbing her ass against his crotch and even lifted and placed one his large hands on her breasts, but he just wasn't taking the bait tonight. Eventually, she gave up hoping for a repeat of the previous evening and fell asleep.
Sky was having a weird dream about swimming naked in a deep lake when, in the early hours of the morning, an unfamiliar but wonderful sensation jolted her awake. Her eyes fluttered open as she realised that her father's penis was pressed up against her pussy lips, straining to enter her.
Taking a deep breath, Sky forced herself to relax. This was a lot more intense than having her clit played with. She could feel her dad's swollen cockhead pressing eagerly at her entrance and it was making her uncontrollably wet. But was she really prepared to let her father fuck her just so her mom could get a good night's sleep? Perhaps that would be taking things a bit far.
The problem for Sky was there wasn't much she could do. If she tried to stop him and he woke up then her father would find out that she and her mother had switched places and that would be even more embarrassing. Besides, she really needed a dick inside her.
The more Sky thought about it, the wetter her pussy became, and she found herself shifting her position on the bed to help her sleep fucking daddy get inside her. Frank was unconscious but his movements were vigorous and once Sky had angled herself correctly her father effortlessly entered her soaking vagina. Grabbing hold of his daughter's hips, the sleeping Frank forced his cock deeper with each stroke until he was unknowingly ball's deep inside his own daughter.
Sky gasped when her dad finally bottomed out inside her. But she somehow managed to avoid crying out loud and waking him despite the extraordinary pleasure of the penetration. Her dad was way bigger than she had expected, and Sky felt slightly overwhelmed by the enormity of the monster cock that had just forced it's way inside her.
"It's gonna be okay," thought Sky as her dad stretched her out, "daddy just needs some release and mom needs a good night's sleep. You can handle this..."
Sky started to relax, and it didn't take long before she was really enjoying herself.
"Fuck, daddy, you're fucking my little pussy so nicely..." she thought, savouring her debauchery and trying to stop herself from moaning out loud. Each and every penetration was bliss, and Sky knew deep down inside that this is what she truly needed. Her parents were making taking care of her sexual frustrations easy, and Sky wondered if that had been her mother's plan all along.
She remembered the coy smile Jane had worn on her face that morning, sitting in the kitchen, dressed in nothing but a revealing bathrobe and it suddenly occurred to her that her cunning mother was probably fully aware of what was happening each time they switched places.
Despite being fast asleep, Frank had plenty of energy, and began humping his devious daughter like an animal. Sky was totally overwhelmed but managed to stop herself from making a sound and all that could be heard was the squeaking of the mattress as her eyes rolled into the back of her head while her father pounded her sweet teen vagina.
