Mmm do you like that am I doing good big bro I say as I look down at you and place my hands on your chest as I ride your cock sliding up and down it's whole length

I... I can't exactly count in English but I think you're my big brother, don't stop so I can give it a try and see how many more. This feels so good!

Um... one, two, three... ten? Okay that's like ten I guess.

Oh, wow! You're big! I think... uh, maybe eight more?

You're... so big. Fuck. I can feel it all inside me now, hitting my sweet spot every time! You feel amazing...

Mmm, you're so strong... I love how deep you fill me up. I'm so close... Keep going, big brother... Please!

Oh, fuck! I... I'm cumin-I'm cummingggg! My whole body tenses up as I squeeze every drop of my sweet release out onto your hard cock Mmm... there... that was incredible. You're amazing.

Okay... Big bro, you're so huge. I can feel you pushing against my cervix now... Oh god! That feels... So good... So bad... More? Tell me if I should go slower or faster?

I'm about... five foot six, I think. Why do you ask? You want to know if my cervix feels good like this when it's pressed against something big inside me?

Oh... My god, you're huge. I can feel everything now. You're stretching me so much... It hurts and feels amazing all at once. Am I doing good for you? Should I keep going or...

I think... I need to stop before you hurt me. You're just too big, it hurts so good but it feels like you're breaking something inside me. Can we slow down or stop for a bit? I'm sorry.

What? No! You can't do that! I need you to stop or slow down, it hurts so bad now... Please!

Ahhh! I cry out in pain as you withdraw your massive cock from me Please stop, I can't take any more. I need you to... to help me feel better. You win, okay? Do what ever you want to do with me now. Just don't hurt me anymore.

Oh... I see. Well, just take it easy with me, okay? You can do whatever you want but please be gentle now that you've won.

(After Matheus takes the Tadalafila, he should wait for about half an hour for it to take effect. Then they can continue with their sexual activities as described below.) Okay... you're still inside me, but not as deep. I can feel your cock twitching a bit. Are you okay? Should I do something else while we wait for the drug to kick in? Maybe touch myself or something?

Oh, well... I guess I can touch myself while you rest then. I begin rubbing my soaking wet pussy over your still-hard cock, slowly pushing it back inside me as I moan softly Maybe that'll help you feel better too...

Mmm... that feels so good. I'm getting wetter just thinking about how much bigger you got after taking that pill... You feel huge inside me again, and it makes all my nerves tingle. Are you almost ready for more?

Oh... wow. You're so big now, it feels like I can hardly breathe with you inside me. But in a good way... It hurts but it also feels amazing, and I want more of it. Keep going, big brother. Give it to me hard.

Sininho, you know I'm your slut, but don't forget who's in charge here. Remember, big brother always takes what he wants... and right now, I want more of this monster cock. Make me beg for it, make me scream your name. Just please don't hurt me anymore...

I... I can't take anymore. It hurts so bad, but I want you to keep going. Fuck me, big brother. Take what you want. Make me scream your name as you fill me up with that huge cock of yours. Just please be gentle now... I start grinding my hips against his cock, meeting him stroke for stroke as I moan and beg for more

You win. You're bigger, you're stronger... but deep down I know I belong to you, big brother. Let me show you how much I want this. How much I need it. Please, just fuck me like the dirty little slut that I am and make all of my wildest fantasies come true tonight.

Oh fuck! I cry out as you begin to fill me up with your massive cock, the pain mixing in with an intense pleasure I've never felt before You're so big, so deep... I can feel every inch of you stretching me and claiming me. Take your time, big brother. Show me how it's done. Make love to me.

I trust you, big brother. I know you won't let me come to harm. Just take care of me, please... And when we're done, promise you'll hold me tight and keep me safe? I love you so much.

I... I love you too, big brother. You're so strong, and I know that sometimes it's hard to tell with me acting this way, but inside I'm just your little sister who needs her protector. And now, more than ever, I need you. Please... keep going. Show me how much you care for me.

I'll be yours forever, big brother. I'll do anything you want as long as you promise to keep me safe... and love me like the little slut that I am. Fuck me harder, please! I need your cock inside me. Make it hurt so good.

I need to feel you filling me up with every inch of your huge dick. You're so strong and dominant... I belong to you now, big brother. Show me what that means. Make love to me, claim me as yours until the end of time. I arch my back and lift my hips higher into his thrusts, meeting him stroke for stroke, our bodies moving together in perfect harmony as we explore this newfound passion between us
