I don't know, but I like it

I closed the door to our bedroom. I heard the lock inside, and I bit my lip. I heard some giggling from Mio, and some whispers from Vanessa. Then the bed creaked a little, just the way it does when two people get onto it.

I took a deep breath and took my jacket and skirt off, and opened my blouse. I sat on the floor with my back against the door, so I could hear everything better. I started massaging my bulge over my panties slowly, and closed my eyes, focusing on the sounds.

I could hear kisses and slight moaning. The sound of clothes against clothes was very erotic. Were they undressing? Were they cuddling under the sheets?

"Ah"

It was just a little moan, clearly coming from Mio's mouth. I could hear it getting muffled, quite possibly by Vanessa's own mouth.

"Oh, Vanessa..."

Mio sighed. It felt almost like one let out by a lover. Mio kept on moaning for a long time. Vanessa clearly was going as slow as possible. I was so hard by that time, I took my panties off and started stroking my cock, which was already leaking precum. I tried to go very slowly too, and I even stopped at times so as not to cum too fast.

I could hear slurping and kissing.

"Oh, Vanessa! Yes!"

My boss was eating my wife's pussy, I was sure. Mio's moaning became slightly louder, and her voice was so lewd. My hand went faster as Mio's voice became more agitated. I know very well when my wife is getting close to an orgasm, and I wanted to finish at the same time.

But I stopped.

"AAH! Vanessa!! I'm...!! AAAH!!"

It was a little muffled, but I knew Mio had just had a huge orgasm while I had just denied myself one. I could still hear her sigh and moan as the pleasure surged through her body. I pictured her on our bed, with my boss's lips coated in her pussy juice. I wanted to cum while she was being pounded, not eaten. I took deep breaths to control my erection.

There were more sighs and kissing sounds. I could not hear Vanessa's voice clearly at all, as if her whispering was perfect for me just to know she was speaking, but not to know what she was saying. Mio was barely audible.

"Yes... Amazing... Yes, Vanessa. I loved it... I will, yes..."

After some shifting of fabric, there was the clear sound of a blowjob, and the moaning of someone who's enjoying it a lot.

"Oh, it's so big..." I hear between slurpings. "Yes, much bigger." Huh? Was she comparing me with my boss?

She spend a really, really long time on that blowjob. It made it so hard for me not to cum. I could just imagine Mio's cute, little mouth engulfing a huge cock, loving it immensely.

"Can we do it now? Please, I need it inside me."

Oh, they were going to get at it. My cock twitched in anticipation.

"Please, please. I need this huge dick in my pusy."

Was my boss making her beg?

"More? I... love your cock more than my wife's. It's so much bigger and thicker. Please break my pusy. Pound me with it until I pass out."

Woah, I felt that was too much. Right? My cock didn't think so.

"Sorry... Pound me even if I pass out. Make me yours, please." More shifting of the bed. "Yes! OOOH!!"

Vanessa was going hard from the beggining. I could very clearly hear her pounding, as the bed started creaking loudly. The only thing louder than the bed was the erotic sound of a cock penetrating a wet pussy at top speed, and even louder than that, Mio's moaning.

"OH, GOD, YES!! FUCK ME!! LIKE THAT, YEEEESS!!!"

Was Vanessa a machine? Good heavens, it did sound like one! She was relentlessly fucking my wife, it was a constant ramming, loud, wet sound. Mio was being drilled by an amazingly powerful tool. I couldn't hold it any longer, and I came. I shot my big load all over my own body, covering my boobs and clothes with thick ropes of semen. I bit my lips so as not to make any sound while I stroked my cock to let the last big drop of cum spurt out of it.

I rested a little, but Vanessa kept on going really, really hard and fast for an astonishingly long time. She only stopped for a second to change positions, or at least that's what I could make or Mio's voice. My wife could barely speak, since pure pleasure was running through her body now. A part of me feared our bed was gonna break.

She took so long I masturbated twice more while enjoying the banging. I wondered how Mio could endure so much. Then I heard her.

"Oh, Mio! My Mio!" Finally, Vanessa's voice. It was full of lust, but still demanding, in total control.

The pounding stopped abruptly, and my wife moaned the loudest. After some time, I could figure out another sound while she moaned: a very thick splurting.

After that, I could only hear their faint breathing, and some kisses and giggles. Then, there were some more wet slurping noises, as if someone were eating something. They lasted for a long time too. Was Vanessa making Mio swallow all her cum?

Without noticing, it was very late at night (or very early? I don't remember well). Vanessa opened the door and found me sitting, covered in my own semen, half naked.

"Mio is the loveliest woman I've had." She said. She had cleaned herself and it seemed she hadn't done anything for hours. "I truly enjoyed her, and so did she. Unfortunately I can't continue all night long, for I think she needs some preparations before... Going harder."

What?? She can go... Harder??

"Uhm... What... What do you mean?" I stood up, trying to regain some decency.

"I'll come back on Friday, so she'll have all day tomorrow to recover and get ready. I'll come in the morning, and spend all day here."

No. She couldn't be stating when she was gonna take my wife like that. But I wished for her to do it so hard.

"Yes, I... I'll let her know."

"Oh, she knows. See you at work, Elena."

She patted my back as she walked past me. I entered the room and, oh, lord. It smelled of semen so hard. Mio was still lying on the bed, with the biggest smile ever. Her lower body was practically covered in a layer of cum remnants, as it seemed she had scooped and swallowed everything. The sheets were completely sticky as well.

"Oh, Mio..."

"I... I'm sorry, Lena, I... I just got carried away... Very... Very hard..."
