Just wing it, what's the worst that could happen

You swing the door to your bedroom open, and see Dennis comfortably reading one of your books once again. At least he had a decent taste when it comes down to those. It wasn't easy to think of a way to break the news to him without getting him upset, but still, you needed to tell him that the whole unprotected sex thing needed to come to a stop. Looking back over to him however... maybe it's for the best to wait at least until he got dressed again instead of while he was displaying his veiny baby stick in all of its glory - and covered in a pungent mixture of your combined sexual goo.

After you sit down by his side, he glances towards you and begins asking you a couple of questions about the book. Turns out he was reading one of your romance novels, and the two of you quickly end up gossiping and talking for a solid hour before your belly rumbles for attention. "Ya know what, how about some lunch? I'll fix something for us," you suggest and he happily accepts. This time, you actually bother to get dressed. A cute little thong, some yoga pants and a loose shirt that was a couple sizes too large. Good enough.

Dennis joins you downstairs in the kitchen while still naked, and together you end up eating a couple of sandwiches in the large living room while watching TV and having a pretty decent time! Before long, you switch over to gaming, and given the sexual nature of things... you decide to casually lie down in front of the plasma screen, tug down your pants and slide the crotch of your undies to the side invitingly. Dennis happily takes you up on the offer and gets on top of you, his virile erection sliding back into your slick lady bits. Connected like that, you two play a few rounds of some generic multiplayer game, with him occasionally giving you a couple thrusts and presumably leaving more spunk inside of you. For some reason, it didn't bother you as much as it should.

At some point during those matches you get a message from Alex, who excuses himself for being so busy. With his best friend still inside your well-worn cunt, you type up a quick "don't worry it's chill, we are getting along well," before hitting the button to send the text message and putting the phone aside again.

It didn't take long before the two of you got interrupted again, this time by Gwen who gasped in surprise upon seeing not just a stranger in the house - but on top of her little sister! "Who is that?! What the hell are you doing? You've got a boyfriend!" she points out angrily while you keep your calm.

"Huh? His name is Dennis, he's a friend of Alex, it's cool. I'm just helping him to practice sex a bit. Wasn't it your idea that sex is supposed to be just a fun activity?" you point out her hypocrisy, but she barely manages to calm down. She really seemed nervous for some reason, still, she grumpily turned around and left the two of you to enjoy your games.

Time passes surprisingly quickly, and you only notice that it's already dark outside when you hear someone knocking on the door. You quickly gesture for Dennis to get up and return to your room while you get up and pull and push your clothes back in place. There's another knock on the door, and you quickly approach and open it only to see your parents standing there, exhausted but happy. "Hey sweetie, didn't burn the house down I see. Good job," your mom teases you before leaning in to give you a hug. While she did, you could awkwardly feel warm semen leaking into your underwear.

"Err... thanks. Welcome back? You're home early, is your vacation done already?" you ask timidly while trying to tightly close your legs to stem the flow.

Your dad chimes in, "Yup! It was a little too busy down by the beach, so we figured we could save up our remaining vacation time for when things are a bit more enjoyable. Where's your sister?"

"Gwen? Upstairs in her room, probably busy with something again," you reply while your parents drop off some bags and get rid of their jackets. Just as you're about to leave, your mother takes your hand, guides you back into the living room and settles down on the couch with you.

"Did you water all the flowers while we were gone? Did you remember to turn off all the lights at night? Did you feed the cat?" It goes on and on while you sit there and try to answer to the best of your abilities. It didn't exactly help that you could feel more cum still escaping your sore slit, seeping through your underwear and into the crotch of your pants. Luckily enough your mother hadn't noticed the somewhat obvious semen stain between your legs.

Yet you do manage to excuse yourself before things got too messy, which still earns you a weird gaze from her while you awkwardly try to return to your room without having love goo running down your leg. As soon as you return to your room, you lock the door behind yourself to make sure your parents wouldn't ask any questions about Dennis. Gah. This wasn't what you had planned, you wanted to get rid of Dennis and get your boyfriend back!

Considering the clock kept on ticking however, you didn't have much of a chance but to suck it up and spend another night with Dennis. Though, two nude teenagers in a small room... it only took another hour before you decide to strip again and decide to mount Dennis yourself. It was hard to explain, but your interest in sex was growing quickly recently. "Amazing stuff," he complimented you while you rode him, your delicate womanhood stretched taut around his erection. His endurance was improving too, he managed to last nearly a minute before you began feeling him soften inside of you, followed by a few thick drops of his virile sperm that managed to escape your body. Good thing your parents weren't nearby, your bedroom had the scent of a breeding chamber by now.

Oddly enough, after rolling off, you don't feel any strong incentive to wash your freshly inseminated pleasure slot. If anything... it felt kind of exciting. Millions of his little swimmers sloshing around in your belly to desperately try and find an egg. It would be unfair to clean your pussy instead of giving 'em a good chance first. Let mother nature sort things out, the way it's meant to be.

Slowly but surely, everything got quiet and even your parents went to sleep. Still, your bed partner had a slightly different idea. After gesturing for you to spread your legs and climbing between them, he's once again getting on top of you. He didn't even need more guidance beyond that, as he easily found your entrance and pushed your battered folds wide open to make room for the fat girth of his dick. You energetically wrap your legs around him as he begins pounding into you while letting your receptive insides massage every inch of his familiar appendage. Even the bed began squeaking loudly in tune to every push, awkwardly announcing to your parents that you were bumping uglies with someone.

The atmosphere at the breakfast table during the following morning was naturally pretty unpleasant. Everybody noticed that when you two left the room, it wasn't your boyfriend by your side. It also was pretty easy to notice that you and Dennis were rather affectionate with each other, holding hands, and most of his actions somehow got a giggle out of you. Gwen looked to be the most concerned one, and was the first one to get up and leave the table.

After finishing your meals, you and Dennis head back to your room. While he goes ahead, you're passing your sister on the way up the stairs. She didn't have any words of wisdom this time around, which was somewhat refreshing. Instead she planted a tiny, blue capsule on the palm of your hand and leaned in to whisper into your ear. "That one should help you two practicing plenty, it's Viagra. You were right, sex is supposed to be fun. Enjoy getting laid without having to worry!" With that, she winked at you and grabbed her jacket to leave the house.

Back in your bedroom, Dennis was collecting a few of his items as well as his phone before approaching you and giving you a casual kiss directly on the lips, which made you feel... giddy and happy, rather than offended. "You've got a nice place here, but I could really use some spare clothes. I'll also have to take care of a few things quickly, but I'll come back tonight or something," he explained. Awww, back to being lonely it seems.

At least you also receive a text message from Alex who announces that he should be able to pay you a visit again soon, which serves to cheer you up at least a little bit. With your sister gone, and your parents doing some grocery shopping, you have the house all to yourself for a while.

Alex appeared out of breath just in time for you two to have some more bonding time before anyone could disturb, and you almost drag your boyfriend into your room before he even had the chance to greet you properly. "Hey, what's gotten into you?"

"I don't know. Since when do you mind having an eager girlfriend? I thought guys are into that?" you wink at him while peeling your undies off and helping him to undress as well.

"Good points, go on. Let's see where this is going," came his answer with an amused smirk.

That's when you remembered the little gift that Gwen had given you, maybe this was just the thing to make things even more interesting! "Here, take this one," you suggest as you grab the blue capsule from your desk and feed it to Alex. "I'm expecting your little guy to stand like it's made of steel after that," you tease your boyfriend while he gets comfortable on the bed. While waiting for the medicine to kick in, you two watch some TV before getting it on.

Just as you were about to pounce him, he reaches for a condom but you pluck it out of his hands and place it back on the nightstand.

"Let's take a tiny risk, we've never done it bareback. Let's try it?" and after considering it for a moment he nods his agreement.

It was nice to be intimate with your boyfriend again, though it somehow didn't feel nearly as exciting as you had hoped when you got on all fours and he finally entered your fun box without that annoying latex layer. It also didn't help that your vagina had been stretched so much recently that you didn't get much pleasure out of his slightly smaller tool. At least Alex lasted a few solid minutes before he hilted his dick inside of you and moaned out in bliss, with your warm walls keeping a snug embrace on his shaft to ensure he could enjoy his climax. It was hot to know he was finally cumming inside of you, and intentionally taking the chance of knocking you up with his seed.

Almost immediately however you could feel something runny leaking out of you with ease. It was only when you looked down and between your legs that you could see his cum steadily leaking out of you, completely transparent and watery in texture? The bed sheets soaked it up instantly. "Huh," you wonder, but Alex already began lowering his weight on top of you, causing both of you to collapse against the creaking bed before you could have another look and ensure it wasn't just your imagination.

A few hours earlier...

Gwen was nervously pacing around her room after that unpleasant family breakfast with the stranger sitting there right next her precious sister. Did they really have sex? That's bad, really bad, her little sister could get pregnant in no time at this rate - but by the wrong person! Some random school buddy! In an attempt to come up with a quick solution, Gwen began to mix a few ingredients into a little capsule as some kind of birth control that a man can use - if she could find a way to make that 'Dennis' person take it without question.

When swallowed, it would rapidly deconstruct any sperm in the testicles into harmless proteins and permanently prevent the production of any more of those pesky swimmers until a remedy is taken. It wasn't the nicest way to deal with the situation but it would solve the current problem.

Upon leaving her room, Gwen ran right into her young sibling, making the whole ordeal so much easier as she handed the capsule over. "That one should help you two practicing plenty, it's Viagra. You were right, sex is supposed to be fun. Enjoy getting laid without having to worry!"
