Breed Mommy-slut

"I think I'll have Mommy-slut help... If that's okay?"

"Of course!" Your mother nods happily, taking a step back as you wrap a hand around Melanie's waist.

Your father, however, hasn't quite caught up with what's going on. "Huh? What's wrong with John?"

"I'm fine, Dad. I've just got an erection." Man, now that's a sentence...

"Oh, okay... This is part of that 'taking care of you' thing, right?" He shrugs. "You guys can use your old bedroom, it's--"

"No thanks," you interrupt, running your fingers through your Mommy-slut's hair. "We're family, we don't need privacy. Besides, everyone's got a lot of catching up to do!"

With that you move Melanie over to the coffee table, gently pushing her down onto the low surface. She smiles up at you as you spread her legs, brushing the sun dress aside to reveal her bare pussy.

"You want to put it inside again?" She asks the question in a pleasant and casual voice, like a cashier might ask if you need a bag.

"Well, last night someone mentioned you and I having a baby," you begin, avoiding the topic of Melanie's husband; no need to complicate things. "I sorta laughed it off, but I mean... We could. Why not?"

Your father fields that question from his armchair. "Uh, because she's your--"

"Right, she's my mom," you continue, pulling out your erect member and letting it fall against Melanie's pussy. "She gave birth to me, so it stands to reason she should give birth to my kid. She's had practice!"

"Mmm, that makes sense," your (original) mother pipes up. She's still standing a few feet away, and it looks like she's paying much closer attention than Carl; her eyes keep flashing down between Melanie's legs as you tap your cock against her pussy lips.

"It--it does," your mommy-slut murmurs, squirming towards you a little. "We should get started... You look so uncomfortable--Ooh!"

She gasps as you penetrate her, and you think you hear your mother let one out as well. You slide slowly inside until you bottom out, letting Melanie's tight, wet passage squeeze you for a moment before you begin to thrust. The table shudders a bit, but manages to stay in place as you rut with her.

"Huh. I gotta say, is quite something." It's your dad again; looks like he's having the most trouble getting used to the new status quo. "I don't think anyone's ever, uh, made love in our living room before."

"That's not true," you grunt, running a hand down Melanie's smooth thigh. "I lost my virginity on that couch. When I was 19, I think."

Your mother bristles. "Wait, what? You brought a girl into our house and--"

"I know, I know. I should have just used you." You wave her over while still pumping into your mommy-slut. "C'mere, Mom. It's okay."

She moves over to your side without hesitation, accepting your embrace. After hugging for a few seconds, you plant a kiss on her plump lips... Then another... And another...

Within moments you're french kissing your own mother, one hand on her waist and another on Mommy-slut's to keep her steady as you thrust.

Huh... That was fast. I thought it would take more to push me into full-on mother-son **** territory, you think. I guess all this role-playing with Melanie might have desensitized me a little.

As you run a hand down your mother's back and grab a handful of her thick ass, you can feel your balls tingling. If you want to get her even more involved in this act of debauchery, it's now or never.
