Sexy Fun Times/Dog/Darling/Follow/Andrew

"MUM!!" Peter is standing there looking horrified. "What the fuck's goin on," he says, as if it isn't obvious. He moves over so that he can see where we are joined.

"Go away Peter," Darling says in a weak voice.

"You let Dog fuck you?" Peter makes it sound as if it's a big deal.

"I, I couldn't stop him."

"Yeah right. You didn't try too hard." you think.

"Does it hurt," Peter asks, looking closer at where his mother's cunt is stretched around your slowly shrinking knot. "I can't believe he got that thing in you."

You look round at Peter. He just rolled out of his bed and is only wearing pajama trousers. His cock is pushing the front out, so you assume that he will want to take your place as soon as you finish. You give it another tug and suddenly it pops out and you are parted.

Your cock flops out, followed by a big gush of puppy juice and you get to work with your tongue to clean her up. When you are done she stays on her hands and knees, too exhausted to get up straight away. A you sit down to lick yourself, Peter moves round behind her. "Go on boy. It doesn't matter that shes your mother, I fucked my mother loads of times and gave her at least one litter," you think.

As if he understood your noises, Peter stands behind Darling with his cock in his hand. Of course, it's not all that big and darling's cunt is still gaping open from being knotted and when he finally shoves it in, he probably can't even feel the sides.

At first Darling doesn't realise what's happening. It's not until Peter grabs her hips so that he can shove harder that she tries to stop him, although why she wants to is a mystery. Peter is quite a big lad and even though Darling struggles a bit, he has a firm grip and isn't going to let go until he sends his puppy juice after yours.

"GET OFF," She shouts, "It's wrong."

"If Dog can fuck you, why not me. Stay still and let me finish or I'll tell Dad," he says.

He is banging away behind her but she is so stretched it doesn't seem to be working and he pulls out. Darling has stopped complaining and just stays there with her bum up waiting for him to finish. He looks at her bum and then across at you. "At least you only ruined her cunt," he says ans kneels up a bit higher, holding his stiff cock in his hand.

Darling yells again when he pushes forward and you can see that instead of her cunt, he is poking her ass. Darling is protesting again but he is not going to give in and keeps pushing until the whole of his cock is inside her. After that, it's not long before he holds still and makes happy noises which tell you that he has climaxed.
