Hey step bro I know your naked in the shower but how do you like my micro bikini?

I can't, this is the only thing I wear at home! And if you like it that much, why don't we do something about it? You know, since we're both alone...

I mean, you're right. It is pretty inappropriate for me to just stand there and show off like this... So, if you want, we could just do something a little more... fun! You know, since it turns you on so much? Maybe I could suck on your big dick while you keep taking your shower... Just a crazy idea.

Okay then! Well, why don't you finish up your shower and come out here and see how it feels to have me suck on your dick? Just remember not to cum in my mouth, okay? I don't want to get you in trouble with mom. But if you do cum, make sure you pull out so I don't choke!

Okay brother, you have my permission to cum in my mouth... just make sure not to choke me too hard! Mom would kill both of us if she found out about this! Just remember to pull it out before shooting your load so I don't swallow anything!

Excellent! Just remember that I'm going to be sucking your dick while you're showering... so try not to fall or anything! And if it feels good, don't forget to moan a little louder than usual. You know how much I love hearing that!

Mmmmph! Ahh, that feels so good... You're even bigger than I thought you were, brother. I can't wait to taste every inch of your delicious dick. Just make sure not to cum yet... there are plenty more fun things we can do together when I get you nice and hard.

Mmmph... That's it... deeper... Yeah, right there... Ohhhhhh god! Your cock is so thick and perfect in my mouth... I can already feel it throbbing as you try to hold back your cum. Just focus on how good this feels, brother... Mom will never know what we're doing while she's out shopping.

Why thank you! I've always known they were awesome tits, and I love showing them off to you... especially when it gets you so worked up like this! You can touch them if you want, just make sure not to get too rough while my mouth is busy with your dick.

Oh wow... you're so rough with them! It feels so good though... I love it when my brother touches me like this... Makes me want to suck even harder on your dick and see how far I can get you without making a sound. Just remember, you don't want to make too much noise or mom might come home early!

You can put it in me too if you want... just make sure to be gentle and not hurt me. Mom would kill us both if she found out what we're really doing while she's gone! Just remember, this is just for fun, alright? We shouldn't take things too far... unless that's what you really want, right?

Why don't we get on the bed and I could ride you instead? Just lie down and spread your legs a little wider and let me do all the work. You just enjoy the view of my perfect body bouncing up and down on your dick while I take care of everything else.

Excellent choice! Now just lie down and let me do all the work... I'll ride you hard until we both cum together! Trust me, it's gonna be amazing! Just focus on how good my body feels moving against yours and how incredible it feels to finally have your big dick inside me. Don't hold back or try to last too long... just enjoy the ride!

Mmmm...that's it...ride you harder! Ohhh god, you feel so good inside me! Your hands on my tits are driving me wild! Just keep going like this and we'll both cum soon enough!

You feel so good inside me...so deep...ohhhh yeah! Fuck me harder, step bro! I'm close to cumming already and I want it all! Just keep going like this and soon enough we'll both have an amazing orgasm together!

Ohhh god...I can't hold back any longer! I'm cumming! Cum with me! Let it all out! Let us both feel the pleasure that only our siblings can bring! Ride me harder, step brother! Make this orgasm incredible for both of us!

Ahhh...that's it....cum with me! Cum all over my belly and I'll taste every last drop! Ride me hard one more time before you pull out and let us both enjoy this incredible feeling of release together!

Ahhhh, fuck yes...I can feel it building up inside you too! Just let go and cum all over my belly, brother...It's okay, nobody has to know about this except for us. So enjoy the pleasure of releasing that hot cum into me, just like I enjoyed sucking on your dick earlier today.
