Forcing your sister

It was a normal day like others, when you where heading towards the toilet as you needed to piss.

When you reached the toilet, you could hear someone inside but the door wasn't locked. You were supposed to be home alone and this is why you were wondering around bottomless in your house.

You had to check, if that was a thief? So you silently pushed the door slightly and saw that your sister Emily was naked, maybe she just had a bath. But she was supposed to be out for shopping with her friends.

You then felt something strange, when you looked down you realised that you were getting an erection, but why? That was your sister!

You kept looking at her, she grabbed the towel and wrapped it around her body. "This is wrong" you thought "She is my sister..". And before she could catch you you went to your room.

You couldn't stop thinking about what you just saw: Your sister's small breasts were small but perfect on her slim body. Your cock was still hard, and strange thoughts were getting in your mind "I need to see more!"

You headed towards the toilet again, but this time she wasn't there. "Maybe she is in her room.." you deduced and moved towards her room.

"Strange, she never leaves the door of her room opened" When you moved closer you saw that your sister Emily was naked in her room, she was going to wear her clothes. Her back was towards you, so you had the chance to stare at that beautiful ass for longer.

Your mind still thinking strange stuff "Maybe I can go inside, but if she sees me? I can handle it!, What if she like my cock?, Oh she is wearing her underwear now, but I wanna see her ass for longer. Maybe I want to fuck her!" and your cock twitched, definetly it agrees with your last thought. So you moved forward and pushing the door, you entered inside her room!

She already wore her underwear, but she was toppless. Emily suddenly turned around and shocked she shouted "OH SHIT! What the fuck are you doing here!?"

Hiding her breasts with her hand she carried on saying "Get out of here!". You didn't reply, but she noticing your cock said "Why you are naked, you perv! And what are you doing in my room!"

"I thought.. I was home alone" you said softly.

"And I thought I was home alone!" she replied confused.

You then moved closer to her and replying to this she shouted "What are you doing!"

You moved even closer and grabbing her arm you said "Now that we are alone, I want you to satisfy this cock!"

Looking down she replied "What are you saying John! You are my brother!"

You pulled her arm and moving it closer to your cock, you ordered "Grab it!"

She tryed to pull back, but your grip was tight. "What!? NO!" she said.

"I know that you have a dildo in your closet, and if you don't listen me. I'll tell mom about it!" you blackmailed her.

"What!? You touched my closet!" She said annoyed and then she said begging "Please don't tell mom! I will do whatever you want but don't tell her!"

"Ok then!" You said leaving her hand and layed on her bed and then ordered "Suck my dick!"

Your sister a bit confused and a bit annoyed, climbed onto the bed and sitting between your legs, she grabbed your cock and began licking it. "This is so weird!" she said carrying on licking your dick.

"Wow! I never thought that one day my sister would be between my legs sucking my cock! Her hand around my dick's shaft feels so nice! And her tongue is amazingly wet and warm!" You thought.

"For how long do I need to do this?" She asked in a soft tone.

"You can stop now!" You said

"Oh thank God!" She exclaimed releasing your cock, then she moved back when suddenly you stopped her saying:

"I'm not done yet! My cock is still hard and I want you to take off your underwear!" you said with proud.

"What! No!" she said, you looked her with a devilish sight and then she said "Ok, fine!"

She took her underwear off and said with anger "Happy?"

You stared at her shaved pussy for a moment and then said "Show me your ass!"

Moaning with anger she sat in a doggy position, with her ass towards you. You moved forward and caressing her ass you said "You've got a very hott ass!"

"Thanks, but now I would like to wear my clothes! " she replied.

Without saying anything you positioned your cock near her pussy and then thrusted it inside her, when you heard her shouting with shock "Oooh!.. What are you doing!"

"Fucking you!" you replied moving inside her pussy, then you said "Feel the pleasure!"

"Ah.. you are my brother.. how can thi..oh..happen!" Her voice was starting to change tone, she has began to feel pleasured with your cock "Oh.. stop it!..oh..John..oh..fuck you...ah!"

"Yeah, I know that you like my cock inside you.. moan my name!" you teased.

"Oh John... I mean this..ah is weird ...Fuck. ..oh...it..feels nice..ah.. yes fuck me..hmmm..ah"

This is when you took your cock out of her and lying back you said "Ride me sis!"

"Oh I need it now!" she said climbing on top of you. Emily began riding you, you could feel her tight cunt around your dick.

Then you switched position, she opened and raised her legs as you fucked her pussy. It seemed like she didn't had any complaint until you felt the urge to cum. "I'm cumming! " you warned.

"Oh.. not inside!" she said, so you pulled your cock out of her, but you couldn't do it on time and some of your cum was released inside her.

"What the fuck you've done! I'm not on pills!" she shouted worried
