Sucing My Sister's Boyfriend

My first oral sex.

I was 18 years old and at home was a party on my father's birthday. barbecue, guests so I drank a glass of champagne. At one point my father asked where my older sister was, I did not know, so I went to look for her.

I found her in her room but she was with her boyfriend. My sister is 6 years older than me, so she was 24 years old and I was 18 years old. Her boyfriend was 30 years old.

When I entered the room she was in sexy underwear with a bra and panties but with her breasts outside. Her boyfriend was completely naked and was sitting on a chair and she was dancing on his lap.

I was shocked, I didn't know what to do and after a few seconds of looking at them my two sisters grabbed my hand and pulled me into the room and closed the door. During this time my gaze shifted from my sister who was only in lingerie and her boyfriend who was still sitting on the chair slowly play with his cock.

Surprised by that scene. I asked my sister: -what are you doing here?

she answered me:

it is also his birthday and this was my gift for him.

I didn't know what to say and my sister continued:

Don't you tell him "happy birthday"? I was watching him masturbate slowly looking at the two of us and I say "happy birthday".

Then he got to his feet and opened his arms and asked me:

Don't you give me a hug and a kiss on the cheek?

I went to him and hugged me. I was wearing a thin dress because it was summer, no bra. When I hugged I felt his cock on my stomach.that feeling, to feel his cock on my stomach, excited me.

He takes a step back, and sits back on the chair.

He grabs again to play with his cock and he says to my sister:

Look hard nipples, she likes what she sees, I like her breasts but I would like to see them without anything on them.

Then my sister said: show her breasts too. you saw him naked, why shouldn't he see your breasts too?as a birthday present for him.

That super hot scene, with my sister in sexy lingerie, he completely undressed with a hard cock and that glass of alcohol made me grab the straps of the dress and pull them down and take my arms out letting the dress slip and stop on my hips.

His reaction was: wow, so hot nice titts

While with his right hand he masturbates, with his left hand he grabs me by the wrist of his right hand and pulls me towards him, saying at the same time: come closer.

So now I had reached the position where he was in the chair with his legs apart, masturbating.and me,on my feet between his legs with the dress on his hips and bare breasts.

He lets go of my hand and puts it on my breasts, without asking my permission, squeezing my breasts in his hand.

The next thing he tells me is to get on my knees.so I get on my knees between his legs. In this position I was with my breasts at the level where his cock was.

Without saying anything he puts his hand on my shoulder and pulls me towards him. and with the other hand he puts his cock between my breasts. this movement made me lose my balance and I put my hands on his thighs.

I felt his cock rub against my breasts which excites me too. then he tells me to squeeze my breasts and he start to fuck my titts.

Was awesome.after a few minutes he tells me to spit on his cock, to slide more easily, which I do, a few times.

After a few such moments he tells me to put the tip of my cock in my mouth. In the heat of the moment I do this.

Then he grabs my hair in the ponytail and pushes me down and at the same time lifts my hips and what at first was titsfuck now turned into me sucking his cock. at first only the tip then more and more.

He started telling me:

Go deeper,That's it,how well you suck it,i can see that you like it,suck my cock,I won't be able to resist much longer and I'll cum in your mouth.

After his last reply I can tell him.

Don't cum in my mouth.

Then my sister intervenes and asks me:

When you suck your boyfriend's cock does he not cum in your mouth?

I stop sucking and say:

I've never sucked a dick before.

Then he says,

You have native talent, you suck it so well.

And that no one has cum in your mouth so far, it excites me even more.

My sister said:

Let it cum in your mouth, you will like it.

I say again: no

Then he gets to his feet he puts both his hands on my head and starts a facefuck slightly and more and more fast.

I hear him moan.

And he says:

I can no longer resist, I will cum your mouth.

I tried to stop, then he grabbed me by the head and picked up the pace, because of the rhythm, I caught him by the hips

I felt his cock tighten even more in my mouth.he puts half his cock in my mouth and I feel it cum.because it was so deep in my mouth, I swallowed the first jet of cum,then he started moving back and forth again and the rest of the semen mixed with saliva flowed on my tits. He lets go of my head and tells me:

keep sucking.

So I suck for a few more moments and his cock is still hard.he takes his cock out of my mouth, gives me his hand to stand up and tells me it was amazing. I turn around looking for something to wipe myself and see my sister completely naked playing with her pussy.

She hands me a towel and tells me she liked the show and now she's sure I won't tell our parents anything. during this time while I took the towel from her, her boyfriend comes, grabs her by the ankle and tells her to sit in all four because he's still horny and he wants to fuck her.she sits on all fours and he comes and puts his cock in it. I finish wipe and I watch them again as they have sex and leave them alone.
