Okay...

Flattered, and a bit proud, from Sid´s compliments, you agree to pay him whatever he asks.

Sid: "mmm....yeah, you´re a smart fella, Matt. You really know what´s best for Alyssa." he says as he stops rubbing his cock and is now just fully stroking it, you stare at it, mesmerized...

In the background, you can hear your neighbors having sex pretty loudly now. He must be really giving it to her, because you can hear the sound of their hips slapping against each other. The woman, you think her name is Angie, is moaning in sync with the slaps, calling him "daddy", over and over again. You and Sid just kind of sit there and stare at each other, while he strokes his cock, you just sit there with your erection hidden, not wanting to compare sizes yet again.

Sid: "How big is your dad´s cock?"

You: "h..huh...? uhm....I don´t know..."

Sid: "Everyone has seen their dad´s cock....come on, how big is it?"

You: "I...saw him...watching porn the other day....he was masturbating, he´s not as big as you....but...big"

Sid: "...think he wants to fuck your fiancée?"

You: "What? No!"

Sid: "Don´t be naïve, he´s a man. He wanted to fuck her brains out the minute he saw her picture."

Sid´s words are punctuated by the slapping of flesh against flesh, and the moans are getting so loud.

After a while of this, finally the slaps stop, as the man grunts: "I´m...cumming...! Fuuuuck!", and the woman yells: "Cum in my pussy, daddyyyy!" Sid is still pumping his cock, slowly, smiling, his cock leaking precum like a faucet on the floor, forming a small puddle.

Breaking the trance, you begin to stand up. As you do, Sid speaks up: "Where ya going, bud?" you freeze in the middle of standing up, and you look at Sid again.

You: "uh....gonna find...Alyssa..."

Sid: "You can´t....you have to clean this up..." he says as he points to the puddle on the floor.

You: "Clean it yourself..."

Sid: "Guess your dad is just going to see a puddle of precum on the floor and wonder what we were up to..." he shrugs

As he finishes the sentence you can hear the bedroom door open.

You: "No! Please, put on pants, at least, I´ll clean it." you whisper, afraid your dad might think you were secretly gay, if he were to see in you the living room with a naked, erect, man.

So you run to get the paper towels, as you do, you can see Alyssa exit the bedroom from down the hall. She´s dressed, but her cheeks are flushed, her hair is disheveled, and she´s holding her crotch together tightly. She looks up and sees you, her cheeks going even redder than before, and she looks away flustered for some reason. You don´t go to her, since you´re hurrying to clean Sid´s precum off the floor.

You: "oh, there you are, babe. What....why are you so....what were you doing?"

Alyssa: "uhm...it´s...we..."

Before she can answer, your dad exits the bedroom as well, pulling up his fly very obviously. zziiiip

Dad: "mmm...I was just showing Alyssa my...special massage technique....It´s something that your mother always did for me, and I thought I would teach her....so she could do it for you."

Alyssa: "Yeah....just another....lesson..." she gives Sid a look, who has now put on pants, and gives her an approving nod. "I just...gotta hit the shower now, if you don´t mind." then she shuffles awkwardly into the bathroom, and closes the door behind her.

You shake your head and hurry up cleaning Sid´s precum off the floor. Your dad swings around and asks: "Got a spill there, Son?"

You: "Yeah...uh...just water..." Alyssa can be heard turning the shower on now, and Sid sit´s down in the chair he was just naked in.

Dad: "Alright...well...I should get going..."

You: "Already? Thought you would stay for dinner..."

Dad: "No, I came....got what I came for, I mean...seeing you propose to Alyssa. What a wonderful woman."

You: "Thanks, dad"

Dad: "You´re all welcome on my boat, any time. Plenty of room, and I need the company."

You: "I can´t really take another week off of school, dad. But thanks anyway."

Sid: "Alyssa and I are free though, maybe we´ll take you up on that offer after we get settled here."

Dad: "That´s a deal! Alright, until then, cya."

After your dad leaves, Sid pulls his pants down immediately again. "It´s much more comfortable this way...." You don´t argue, since you´ve gotten so used to seeing his naked body.

Sid: "I´m glad you agreed to the advanced training, Matt. It´s going to be great for us all."

You don´t remember explicitly agreeing to anything, but you just shrug.
