Make him pull out, it's too dangerous

Considering you had never been on ANY kind of birth control and your vagina was pretty much as unprotected and ripe as it could be, you decide that it's not worth taking such a huge risk. Between the creaking noises of your bed, you raise your voice to get Frank's attention. "D-don't! I don't want you to cum inside me. Don't!" You keep on repeating yourself, and after a few more thrusts he's shoving himself forward and burying his entire manhood inside of your vag. Nnh!

"Then hold still," he demands with a raspy and weary voice, seemingly trying very hard not to have an orgasm. "Damn you're hot. Are you even legal yet? How old are you again?" In the meantime, you can feel the chubby girth of his erection within you, keeping you stretched wide open. You could literally feel every single vein that adorned his dick, it was fascinating just as much as it was scary. You're so nervous that your body begins tensing up... your pussy snugly tightens its grip around Frank's cock, and the shaft suddenly twitches in response.

"Huh?" you look up at Frank in confusion, only to feel another pulsing throb inside your crotch. "It's fine... just... hold still." His dick begins throbbing more rapidly, a good ten times before it ceases the constant movement. You assume that he must be struggling real hard not to climax, really doing you a favor by respecting your wish! "T-thanks," you stutter shyly while looking up at him, while he's still got that tense look. As your eyes meet, there's a final, strong twitch inside your crotch before he shakes his head and begins pulling out. "No problem..." He's so charming and understanding that you're even starting to feel all... warm and squishy, in your tummy! That must be what love feels like...

However, he stops halfway, looking pretty concerned and thoughtful before pushing right back into you with a soft squelch. "Ahnn..." Everything was sensitive down there... "Since it's your first time and all..." He slides his hands underneath your bum, and begins lifting you off the bed while still inside you. "Some quick lessons. It's important for a girl to pee after sex." He tightens his grip on your rear, and holds you extremely close against his body as he begins carrying you towards the door!? "I'll help you with that today, but in the future you have to do it yourself."

While his cock was still in your twat and you were awkwardly looking back at him, he opens the door and begins carrying you to the nearby bathroom. He's accurately lowering you onto the toilet seat upon arriving - you didn't even have to do anything yourself! His dick simply plopped out of you just before you touched the seat. His hands move to your thighs and he quickly closes your legs as you begin feeling a steady trickle of fluid leaking out of you. Odd, it hadn't even felt like you began peeing yet... ?

"See, that's how you gotta do it every time after sex. Just keep your legs closed until all the liquid is gone." Considering he was vastly more experienced than you were, you simply nodded along. The only knowledge you had came from badly recorded movies that probably didn't have realism as focus...

It was a strange situation to begin with, here you are, sitting on the toilet without your pajama pants, your lady bits still all wet and excited, while your father's best friend was standing in front of you with his dick still dripping remnants of your pussy juices - after he's been balls deep inside of you. Life sure can take an unexpected turn sometimes...

... and just like that, you suddenly see your mother entering the bathroom, followed by an immediate gasp as she sees the two of you partially naked and clearly having had sex. "Oh!" she exclaims. "I didn't know you two are in here. Or that you are dating! Is that a new thing? Oh my goodness." She seems more happy than anxious however. You on the other hand, felt a rush of panic and adrenaline! She knows! She already knows! You lost your virginity mere minutes ago, and she already found out! This is SO embarrassing!

Frank is quick to take charge upon seeing that you were clearly way too uncomfortable to come up with a good response. "Us? Oh yeah, we are dating. She's always sitting in front of the computer, you know, so I figured someone has to teach her some new things. Plus it does help that she's got a super tight pussy tugged away between her legs." Oh goddd! Sure they're adults and talking about sex is probably all normal to them, but this was killing you! The only thing you could do right now was glancing back and forth as they took turns talking.

"Oh, I'm glad she's taking care of that part at least. Considering all that gaming nonsense she's up to, it's good that she's good for something," your mom teased you casually. "Plus, if you two need condoms, they're in th-"
"-that's fine," Frank interrupted her. "Sarah's more of an adventurous type. She prefers it bareback, and there's no way I'd make her suffer through feeling some stupid latex layer separating us when it matters."

"I see, that's commendable! Not that I mind, the sooner I get some grandchildren the better," she replied with a smirk.

"E-enough! Mom, some privacy please?" After a sigh, she reluctantly nodded and wished you two a good night before departing. Good thing too, since the constant dripping from your twat had come to a stop. As you get up however, Frank catches a glance of the cute little slit of yours, and reaches for your hips to turn you around and bend you over the toilet for another round...

In the meantime...

Your mother sleepily returned to her husband, though she had a wicked grin on her face and her husband immediately noticed. "What's up, what happened?"

"You won't believe it, but it seems like our daughter got into a relationship with Frank! How about that... and not only that, but they seem to have sex already too. Without protection. Sarah didn't even notice that the entire bathroom was smelling of sperm because of her... probably took his entire load without a fuss. Which makes me wonder, didn't Frank mention a while ago that he had a vasectomy?"

"I dunno...," he responded thoughtfully. "I think he had it reversed not long ago."

"Ah, I guess our little girl started taking the pill then. All grown up! I had no idea our daughter can be so self-sufficient when she wants to be."

"Yup. Life's full of surprises." With that, he closed the book he was holding and dimmed the lights.
