Frank was making weird grunting noises and increasing his pace and Sky was afraid it wouldn't be much longer before he deposited an almighty load of spunk inside her. She had to think fast. How could she stop her dad from cumming without waking him up?
Her daddy's dick felt so good inside her that it took pretty much all her willpower to intervene, but Sky eventually managed to slip off her father's penis before they had an accident.
"Wow, that was close!" thought Sky, relieved, even though her pussy still wanted more.
But her sleeping father had other ideas. Being on the verge of a massive orgasm of his own, Frank's instincts kicked in and he grabbed hold of his daughter and forced himself back inside her before she could react. He held her so close this time that she couldn't get away and Sky began panicking that she may have no choice but to wake him unless she was willing to let her father empty his balls inside her.
Sky's brain was malfunctioning as she tried to work out what to do next and a part of her really wanted to know what it would feel like to have her Dad cum inside her. She imagined the way his cock would throb and the way his spunk would coat every inch of her pussy, and just imagining the potential glory of that moment gave her another, even more momentous orgasm. Then, just as the situation grew desperate and Frank's grunts reached a volume which indicated he was on the verge of ejaculation, Sky got a hold of herself, slipping off her dad's dick in the nick of time.
Once again, her sleeping father reacted instinctively and grabbed hold of her, but this time she was read for it and lowered herself on the bed to readjust her position. He missed the mark, but Sky miscalculated and couldn't help letting out an audible yelp as Frank found an alternative target for his yet to be satiated member.
"Wrong hole Dad!" screamed Sky, silently to herself, as her father aggressively forced his cock into her asshole without any lube. Sky had never had any desire to engage in anal sex and the initial penetration was pretty uncomfortable. Having been in a dreamy state of half-sleep, she now found herself fully alert to the situation.
She should wake him. She should explain. But the memory of her mother's contented face held her back. This was their secret pact, and she wouldn't break it. Closing her eyes tightly, Sky tried to relax her sphincter, willing herself to relax.
Thankfully, Frank came almost instantly from the pleasure of having her unforgivingly tight teen anus wrapped around his fully engorged, cum-spitting member. But little could Sky have known that her tight ass would also keep him erect or that his cum would serve as the perfect lubricant as his sleeping brain instructed him to just keep fucking her.
The night stretched on, a tangled mess of emotions and indecent pleasure as her father worked her virgin asshole open using his own cum for lubrication. Sky had never done anal before and it was way more intense than she could ever have imagined. To her surprise, after the initial shock and discomfort it started to feel pretty good and then after a while it suddenly transformed into the deepest most mind numbing pleasure. She could never have imagined that being fucked in the ass could feel so amazing, especially when the dick up her bottom belonged to her father.
Sky didn't understand the physiology of the situation. Did she have more nerve-endings in her asshole or was it just fresh compared to her pussy that had been pounded open for most of the night? Whatever it was, she decided she liked it, a lot, and despite her initial shock, her night of incestuous pleasure was just getting better and better.
"Yes, daddy, fuck my tight little asshole!" she thought, lying there like a rag doll and letting her dad do all the work while she focussed like a laser beam on the bliss of having him inside her.
"I hope my daddy fills my naughty asshole with more cum," she thought, unsure why the idea so delighted her. "Keep going daddy, I need more. You're making me cum!"
Sky's asshole kept stretching open, making it easier for her father to thrust in and out of her and the mixture of her pussy juices and the cum that coated his cock smoothed the process nicely. Sky began to have multiple orgasms that ebbed and flowed one into the other in an unending stream of sexual delight. She had let go of her worries and totally accepted the situation, giving herself over to her most perverse instincts, desperate for her father to deposit more cum inside her sloppy receptive asshole.
When Frank eventually reached his climax and unleashed a torrent of fresh cream inside his 19-year old daughter, he cried out in his sleep. Sky joined him, moaning in ecstasy, not even caring whether she woke him or if her mother could hear them in the bedroom down the hall.
Frank kept pumping her ass until his balls were emptied and Sky's whole body vibrated with pleasure as she tried to calm down and process what had just happened. Eventually her dad went soft and slipped out of her. A stream of thick cream oozed from her gaping asshole.
It took a while, but Sky eventually feel asleep again, although when she woke up in the morning her ass was sore and exhaustion, both physical and emotional, clung to her flesh like a second skin. Now she truly understood why her mother wasn't getting enough sleep and was so grumpy all the time. Nevertheless, as she crawled quietly from her parents bed, a sense of satisfaction bloomed within her. All her sexual frustrations had melted away.
Downstairs, Jane greeted her with a warm smile and a plate piled high with fluffy pancakes.
"Good morning, sleepyhead," she said, her eyes twinkling. "Did you sleep well?"
Sky didn't hesitate for a moment.
"Amazing," she replied. "The best night's sleep ever."
