Fingers

I'm almost shaking with nervousness and I can see that she is too. "Are you one hundred percent sure?" I look up and down at her smoking hot nubile 18 year old body.

Mia spreads her thighs apart a little more. "Well I trust you big brother, so if anyone is going to play with my kitty I want it to be you."

I lean closer to her and use my left hand to pull her now very damp bikini bottoms off to the side, her pussy is an innie. I take a deep breath and put my index finger against her small clit.

I start to make circle motions with my finger. "This is your clitoris although most peole shorten it to clit."

Mia starts grinding into hand to get more pressure from me. "That feels so good big brother. Can I try for myself?"

"Of course you can babydoll." I pull my hand that was playing with her away while still holding her bikini bottoms to the side.

Mia slowly brings her hand to her clit and starts rubbing it herself. "Mmmm, it feels so good."

I'm having a hard time controlling myself, watching my baby sister masturbate it the hottest thing I've ever watched. "Ok while you do that I'm going to show you another thing." I bring my index finger from my right hand to the entrance of her soaking wet vagina. "This is your vagina, or pussy." I slowly slide my finger in, just past the fingernail. "Some girls like it better when their clit is being rubbed and some like it better when there is something in her pussy." I push my finger in until it my knuckle gets in the way. "How does this feel?" I knew she would be tight but it almost feels like it could only take one finger.

Mia moans. "It feels... full." Mia is getting closer to an orgasm.

I slide a second finger in. "How about now?" Mia seems kinda lost in her feeling of ecstacy. I start slow at first to finger fuck her. I don't wait long to pick up the speed that I think she could handle for her first time. At this point her pussy is making very loud wet sounds as I finger her very tight pussy while she is making really quick circle motions on her clit.

Mia is really struggling to form any kind of words in between moans now. "Uhhh...but...Chloe...seemed to rea...lly like...in her...butt...can you...show...me...how to...do...that."

I was not expecting that, taken aback I stumble on my words. "Um, sure. I uh. Ok if you." I take a deep breath and think about what I need to say. "Ok, I will just have to get some lube. Do you think you can take over for me while I'm gone?"

Mia smiles from ear to ear. "Yay! And yeah I think I know what to do?"

As I slide my finger out of her dripping wet pussy she pushes two of her fingers in to fill the void. She doesn't loose the pace that I had.

"I'll be right back." I open the door and poke my head into the hallway to see if anyone is there, coast is clear. I step out and silently close Mia's bedroom door behind me.
