Sure, a relaxing end to an unusual weekend

Gwen knocked on the door shortly after the sun began setting, and you were already dressed and prepared. As much as you absolutely needed to be. The bra was uncomfortably as heck, so after a while, you stuck to wearing nothing more than undies and a large shirt. It covered your modesty, but also felt much more comfy than any of the stuff Gwen tried to make you wear. Even now you could feel her frowning at you with your unladylike choice of clothing. At least she didn't need to be afraid that you would seduce anyone in such an outfit.

The two of you walk downstairs and see your dad already on the couch, leaving just a spot by his side and an old armchair closer to the TV. Of course, before you could even make a choice, Gwen already insisted on having the armchair for herself! Right, that reminds you... it was her turn to pick a movie this week. Lord have mercy, hopefully it won't be another one of those awful movies she watches in her spare time...

Without much concern for where you sit, you shrug your shoulders and join your father on the couch while Gwen takes a seat on the armchair. Having a bit more space available was kind of neat anyway! Gwen used a remote to dim the lights until the room was almost entirely dark, and with a few more button presses she also started the movie of her choice. Against your expectations, she really did **** her movie priority rights, and chose some silly rom-com movie!

Well... that's as bad as it could get, but still, it was yet another way to kill time. Right now, that was the only thing you cared about anyway. The sooner you get back into your old body, the better.

Your father seemed pretty displeased with the movie choice as well, since rather than continuing to sit upright and paying attention to the movie, he placed a pillow on the armrest of one side of the couch while lifting his feet up and onto the other end. To make room for him to lower his head onto the pillow, you briefly get up to give him a chance to lay down comfortably. He did however now poke your side, and gestured that with the way you were sitting, you were blocking the view at the TV screen.

Hum... after quickly considering your choices, you simply grab another pillow and place it just next to the armrest, so that his head was still slightly higher up when you lay down yourself, and both of you could watch the movie.

With the way you two were lying there, you were just one short movement away from cuddling and spooning... it's around that time that you move your petite hand under the pillow, and feel something touching your fingers? You curiously pull it forth and find it to be an... empty condom wrapper?! It even felt a little dusty. Gee, for how many weeks was that one there already? Unless... ! Did your dad place it there?

Oh. Oh... so that's why he wanted to lie down. Well it sure as heck is a more entertaining way to pass the time than watching Gwen's movie with full attention, that might just give you the urge to shoot yourself. Since your sister was currently looking towards the screen, you quickly use the chance to pull a small blanket out form under the couch. It was only 2 or 3 feet in length and just enough to cover the most important bits, but you still raise it up and place it across your midsection as well as your dad's. Gwen can't blame you for wanting to feel a little warmer, right?

You then slowly and carefully reach under the blanket, grab the waistband of your thong and slide it right down to your feet before sneakily grabbing it and lifting it up to place it on your dad's small pillow. He looked at you in surprise, which was somewhat unexpected since this was his idea, but he smirks and gives you a slight nod. His strong hands move underneath the blanket now, and you vaguely feel him fidgeting around for a moment. Was he already wearing the condom, or putting it on now? He probably also needed to pull his underwear down a bit. What does it feel like to have sex with a condom anyway?

The answer came very soon, since his hands slid forward to your bum cheeks to spread them apart and give him better access to your womanhood. There was the feeling of a familiar, bloated cockhead bumping against your slit, and with a single demanding thrust, he buried the awkwardly large mushroom-tip right up inside your cunt. "Nnh!" you gasp softly, but luckily not loud enough for Gwen to hear it. At least your dad got the hint, since he started entering you more gently. Even with latex wrapped around his dick, you could clearly feel every bump and vein along the length of his cock. It was a very unique feeling that you couldn't compare to anything.

Like before, it was the angry purple crown of his appendage that nudged against your cervix and caused you to tense up for a moment, as if to once more remind you that your pussy was now being claimed by your own father's erection. You playfully tighten your pink walls around his dick in response, knowing fully well that his slab of meat wasn't even a tiny threat for as long as it's wrapped up. You squeeze down on his cock yet again upon realizing that it was little more than a warm dildo to you right now, entirely serving your needs and pleasure, not the other way around!

Your father slowly leans forward to whisper into your ear, "Slow down with the teasing, you're already getting me close!" It did actually sound like a complaint! You smirk in response, but give in to his wish. Can't blame him for wanting to enjoy your vag... still, even now you could feel that you two created an airtight seal down there. He was stretching the fragile lips of your pussy to the limit!

You relax your lady bits while he softly slides in and out of your slippery twat, moving at a constant pace while Gwen still had no clue that you were getting fucked just a few feet away. She was probably already struggling again with her needs and an urge to jerk off, while you had your stuff taken care of.

It continued like that for half an hour at least, before you felt your dad's thrusting getting more irregular. Before you had a chance to investigate, he simply pushed his erection up to the balls into your by now drenched cunt and held himself there. Your heart beats faster for a moment! It's then that you feel his dick suddenly throbbing and thrashing against the delicate insides of your pussy. For a second, you really appreciate that he decided to use a condom for this encounter.

His veiny appendage continues twitching rapidly at least ten more times before it ceases moving around.

With a quick glance towards Gwen, you breathe a sigh of relief. She hadn't noticed a thing, hah. You're having all the fun, and she's none the wiser. You enticingly grind your bum cheeks against your dad's crotch, completely burying his cum-drooling rod inside you. However, the only response is that it shrinks and gets soft, its natural purpose now fulfilled.

The movie in the meantime was becoming slightly more entertaining. A few jokes here and there, and the romantic main interest of the movie was finally getting laid with the girl he wanted. It was apparently exciting enough for Gwen to giddily get off her seat for a second to clap and applaud in pure glee... girls, right?

It came as no big surprise when you felt something stirring in your loins - and it wasn't you. Your father's sleeping buddy was coming back to life in small pulses, gradually growing against the tightness of your cunt and making room for itself. You wriggle your behind lightly to help his dick in its attempt to grow back into its magnificent, fat girth.

And it does. In no time, you can feel your discomfort rising back up while your pussy struggles to accommodate the monstrous organ wedged inside you. It was also kind of a thrill though... knowing how taboo it is. Only a thin latex barrier preventing you from committing a terrible mistake - Gwen would probably pick you right up and throw you out the window if she knew that your vagina was currently **** to provide space for a perfectly virile, fully erect dick. You playfully squeeze down on it, knowing fully well that it's little more than a tame rod for you to enjoy. It's not your fault that Gwen never dared to have some fun.

As your dad began pushing into your twat more thoroughly, you felt that he was starting to reach deeper in than before. He was stretching the very end of your cunt, to completely take advantage of every inch you could somehow make room for. Soon enough, you began feeling your battered pussy lips kissing his ball sack each time he completely hilted his rod in your body. It was impossible to understand how he managed to fit the thing inside you, but he did!

For the remaining duration of the movie, he lazily slid in and out while your tautly stretched labia remained tightly around his immense size. It's good that you're as young as you are - otherwise your lady bits wouldn't be nearly flexible enough to sustain that kind of constant humping...

When the movie ended, he was still gently fucking you. Gwen noticed that neither of you behaved oddly or even kissed for the entire duration, so as far as she was concerned, the two of you were simply cuddling. Not at all unheard of, for family members to cuddle while watching TV. She did however raise her hand to her mouth to hide her yawn. "I'll go upstairs and brush my teeth. You gonna join me soon?"

"Y-yeah," you blurt out, while your dad was still repeatedly bottoming out inside your snatch. With Gwen now looking right at you, you were getting increasingly nervous about the possibility that she figures out what you are doing.

"All right, don't take too much time." While she was busy putting away the TV remote and picking up her keys and smartphone from the table in front of you, you suddenly felt a familiar throbbing in your loins. Dad's cock once again began pulsing and bouncing against your snug comforts, but considering how tight you were, it was securely trapped inside. Gwen leaned in to give you a kiss on the cheek just when you felt the last few twitches of his dick, leaking his semen into the condom reservoir. By now it was probably pretty full, but considering how flexible latex is, you couldn't feel anything unusual.

"I... won't. I think we're done," you smirk subtly. "I'll be right behind you, go ahead." With a pleased nod, Gwen moved upstairs.

In the meantime, you felt your dad sliding his hands underneath the small blanket and fidgeting around a bit while pulling out. That was... unpleasant to say the least, you were sore as heck, and there was an audible suction noise when his girthy crown popped out of your pussy for the first time in... hours? Careful not to push you off the couch, he guided you onto your back and placed his pillow underneath your rear, exactly the thing you needed with your aching crotch! "Thank you!" It probably wasn't often that a teenage girl thanked him right after a couple hours of sex. Thankfully, the blanket still covered your sore genitals.

"I'll be back in a moment." Completely naked, your father got off the couch and made a quick trip to the kitchen before returning to you with a glass of water and a tiny pill. Considering how much your crotch was aching, you figure it's a painkiller. After all it probably wasn't the first time he fucked a pussy as tight as yours, and knew how unpleasant the aftermath could be. Even if it wasn't, you just had sex twice, his balls were spent, both of you were completely exhausted, and there was nothing that could still pose any kind of risk to you at this point. Your body was begging for a chance to rest and sleep.
