Helping my sister's hubby jerk off

She tells me how big your cock is

and how much you get her off.

So I'm just curious to see, you know, what you have.

She doesn't have to know.

I'll never say anything.

It's innocent.

But fun.

If you wanna play.

So why don't you show me what my sister's been working with?

Take the cock out of your shorts.

Start stroking it.

Gripping it as if my mouth was all over it.

Making it hard.

and get really wet.

Start playing with your balls too.

Are you getting hot?

Wouldn't you like to see who gets better head?

I'm really good at sucking dick.

I love to suck that big hard cock.

I'm filling my mouth up.

My sister's a bit of a prude, isn't she?

I've just been really lucky to have a cock to play with that's that big.

It's impressive.

So I bet you've been imagining what I look like.

It's only fair you showed me yours.

I couldn't show you something.

How does that compare to my little sister?

Does it make you hard?

Horny?

I keep stroking my cock while you look at my boobs and thinking about your dick going in between.

Pleasing yourself.

Watching them squeeze in between.
