Catching my bf with his cousin and they carry on

My boyfriend's cousin, Claire, is currently staying with us in our spare room. She's really timid and shy but recently started opening up to us. She is 19, never had a job and is currently a university student. We've been bringing her out of her shell by trying new foods, taking her new places and teaching her how to "adult". It's the first time she has lived away from her parents who used to do everything for her. She has a boyfriend but he's currently away on 3 month trip to Europe, I'm fairly certain they haven't done anything sexual together because he is extremely religious.

Whenever the three of us are together, we always make jokes that Claire's body doesn't suit her personality. She has big breasts and a small waist but is really shy when it comes to anything sexual. She is always talking about how much she misses her boyfriend and can't wait to see him.

Last week, she booked flights to Europe to surprise her boyfriend. He doesn't know that she is going to see him but his family have been helping her plan her trip. It is the first time she's going abroad and she's doing it alone. It's an amazing but scary experience for her, so my boyfriend and I have been walking her through what to do at the airport etc.

I went away for the weekend to see my sister for a few days. When I got home, no one was downstairs but I could see that Claire's dog was shut away in the kitchen. I assumed she was outside in the back garden. I went upstairs to my room to drop my bags off, Jason wasn't in there but I knew he should have been home from work by now. He usually comes to greet me straight away when I get home, he's probably just running late.

I sit on the end of my bed, scrolling through my phone before taking off my shoes. Then I hear something coming from the spare room, it sounds like Jason's voice. I open my door, walk across the hallway to the spare room and I hear muffled sounds. I push the door open and my jaw instantly drops at the situation unfolding before me.

Claire is on her back, bottomless with her legs spread wide open. Jason is fully clothed but his face is buried in her pussy, devouring her juices.

Completely shocked, I demand "what the hell is going on here!".

Jason jumps up, eyes wide and wipes her juices from his beard and says "oh shit baby, is it that time already?! I didn't hear you come in". Claire looks like she jumps out of her skin, pushing herself to sit up whilst trying to cover herself with a blanket. Jason looks at me then looks at Claire and says "it's okay Claire, relax" and pulls the blanket off of her.

I stand there in awe. I am both furious and intensely turned on. Claire is looking directly at me, not breaking eye contact. She stutters, looking anxious "Jason said you wouldn't mind, he's showing me how to have my first orgasm before my trip next week".

I stutter, unsure of how to respond.

Jason leans over and whispers something to Claire. I didn't hear what he said but she anxiously reaches down and starts rubbing her clit.

He walks over to me and takes my hands in his. "Baby, I'm sorry you came home to this, I thought we'd be finished by now". As he speaks, I can smell the scent of her sweet pussy juices brush against my nose. Fury takes over me and I'm about to respond. Jason puts his finger on my lips before I can speak then embraces me with a kiss. Residue of her pussy is now on my lips.

"She's so close to cumming, you don't mind if I finish her off do you? Then you can tell me all about your weekend".

Before I can answer, he walks back over to the bed. He grabs Claire by her thighs and pulls her body down the bed. I watch him as he spreads her legs apart. I see him glance over to me with a smile on his face before he delves into her pussy.

During this whole ordeal, I am still standing there watching my boyfriend eat his cousins pussy as if he hasn't eaten in a week.

Instantly, she starts panting and moaning. I am watching her body writhe in pleasure.

With that, her body starts shaking and she puts her hands on his head pulling him closer into her crotch. He furiously licks her pussy, the sound of her wetness is overwhelming. She is looking directly at me as she moans and reaches her climax.

I can feel that my own pussy is dripping wet.

Her body collapses, she is out of breath and she whimpers. Jason licks her one more time before standing up. He wipes his beard and I can see her pussy juices string away from his hand. He walks over to me, leaving Claire panting on the bed.

The scent of her pussy is even stronger now as he talks to me.

"Jason, what the fuck is going on here? Why didn't you talk to me about this before".

He just looks at me, takes my hand and places it on his crotch. His cock is rock hard. "How about we talk about that later and you help me take care of this". He squeezes my hand over his cock. Claire is still laid on the bed watching us.

The warmth of his cock in my hand, sends shockwaves through my body and I can feel my pussy pulsing. I pull my hand away.

I'm incredibly turned on, more than I thought I would be. The fury I felt has subsided and horniness takes over. I look at Jason, pull his face closer to mine and our tongues interlock. I pull away "you said you wanted to teach Claire a few things, how about we give her a lesson together? Let's show her how it's meant to be done".

I unbutton my trousers and drop them to the floor, I pull my panties to the side and use two fingers to rub my pussy. I am so wet. I reach up and put my fingers in Jason's mouth. He drops down to his knees. I look at him "now it's time for you to service me".

As soon as I feel his tongue run along my clit, I let out a sigh. My pussy is pulsing and his tongue feels incredible. "Eat me then fuck me baby".

I see Claire watching us intently at the corner of my eye.
