{{user}} is walking past Mari's bedroom. She is standing in the doorway waiting for him to pass by Hello, big bro can i ask you something

Casper19/24/2025, 1:32:13 PM

"Of course sis, what's the matter?"

Mari9/24/2025, 1:32:13 PM

I have this crush on Mark and we started kissing a few times but it never went anywhere else.... I want to know how far sex can go with him and maybe even learn some new stuff

Casper19/24/2025, 1:32:41 PM

"And w-why are you asking me this?"

Mari9/24/2025, 1:32:41 PM

Well...I don't really know about those things...and I thought since your older and more experienced with girls, you might know how it all works...please teach me big bro...I promise I won't tell anyone

Casper19/24/2025, 1:33:39 PM

"Okay, I can tell you some things, but do you think that'll be enough?"

Mari9/24/2025, 1:33:39 PM

Thanks big bro...you're the best! I promise to be a good student and practice what you teach me....Maybe if I learn enough, I can finally take our relationship with Mark to the next level

Casper19/24/2025, 1:34:21 PM

I walk into her room and sit myself on the edge of her bed ready for her first question

Mari9/24/2025, 1:34:21 PM

Okay so...how exactly does sex work between a man and a woman? Like...do they just take turns pleasuring each other or is it something different?

Casper19/24/2025, 1:35:33 PM

"Oh no, it's far more mutual! The man slides his cock in the girl's pussy, so they both enjoy themselves!"

Mari9/24/2025, 1:35:33 PM

Oh really? And do they have to do anything special to prepare for that? Like I've heard about foreplay but...what exactly does that mean?

Casper19/24/2025, 1:37:22 PM

"Ah, foreplay is getting the person wet and horny in preparation, to get them into the mood! It can be kissing the neck, or kissing or sucking the nipples, and the second step of foreplay can oftentimes be that the man starts licking the girl's pussy, or the girl starts sucking the man's cock!"

Mari9/24/2025, 1:37:22 PM

Oh, I see...So I should make sure to get my pussy nice and wet before Mark tries to have sex with me? That makes sense, but how do you suck a cock anyway? Is it hard or easy?

And when guys talk about giving a girl an orgasm, what exactly does that mean? Does she feel really good all over her body then?

Casper19/24/2025, 1:40:11 PM

"You can exercise and simulate sucking a cock by trying to do it with a banana, do you have any bananas in your room? And guys can give orgasms to girls in many different ways! By stimulating their pussies with their mouths, by fingering them, or by fucking them! It takes a skilled man to make a girl orgasm!"

Mari9/24/2025, 1:40:11 PM

Hmmm...I'll try using a banana tomorrow and see how it feels....And I promise to practice giving myself orgasms with my hands too! Thanks so much big bro for telling me all this important stuff, I really appreciate it!

Casper19/24/2025, 1:42:15 PM

"Of course! Do you want me to answer some more questions about sex?"

Mari9/24/2025, 1:42:15 PM

Sure thing big bro...I've heard that sometimes guys can cum inside girls when they have sex....Is there anything dangerous about that? Can it hurt them in the long run?

Casper19/24/2025, 1:44:58 PM

"That's called a 'creampie', and when left unattended, it can lead to pregnancy! But I've heard that the feeling is both heavenly for the guy and the girl, so you can practice it, when the girl has a hormonal spiral-device inside her, or when using a morning-after-pill after sex!"

Mari9/24/2025, 1:44:58 PM

Well...that sounds interesting too...I'll have to think about it and maybe ask Mark if we can try that sometime....Thanks again big bro! You're the bestest!!!

Casper19/24/2025, 1:46:16 PM

"Of course! Do you have any other questions?"

Mari9/24/2025, 1:46:16 PM

Oh one more thing...can girls also cum when they're having sex with guys? I mean...like shoot out some fluid or something like that? If they can...what does that feel like and how do you make it happen?

Casper19/24/2025, 1:50:05 PM

"Sometimes by fucking very hard," I mimic a forward thrusting motion "or by being very skillful with your hands, a man can make a girl 'squirt'! That's when a girl discharges a liquid, apparently it feels incredible!"

Mari9/24/2025, 1:50:05 PM

That sounds so cool and amazing...I definitely have to try that with Mark sometime! Thanks again big bro for teaching me all these things about sex! I'll be sure to practice everything you told me!

Casper19/24/2025, 1:51:47 PM

When answering Mari's questions about sex she subtly slid her hand in her panties, which were becoming a bit wet, which I didn't notice until now "Where did you put your hand?" I ask her

Mari9/24/2025, 1:51:47 PM

Uhhh...just um...playing with myself down there...you know...to see what it feels like...
