Their sisters eat your son's creampies

On their respective 18th birthdays, in front of a crowd of all of your sluts, both of your sons quickly came in their mothers' pussies. And then on both occasions their sisters kneeled down between their mother's used pussies and drank up their brother's cum.

Isabella Jr. lapped up Zach Jr.'s cum from her mother's cunt. It was a cum-pussy juice cocktail featuring ingredients from two of her favorite people.

Likewise Sophia Jr. loved it when her younger brother's warm mess flowed out of her mother's pussy right into her hungry mouth. This wasn't the first creampie Sophia Jr. has eaten from her mother's cunt (you've given her that honor many times), but there was something special about her brother's young virginal cum.

Now imagine you are an 18 year old boy - it's your 18th birthday actually - and your mother and your older sister are naked in front of you. Like you can see their tits up close and even examine their pussies. Imagine you could reach out and touch them - feel their breasts and slide a finger inside them to feel their pussies.

Keep imagining this - imagine you actually fucked your mom - like she told you to fuck her and you came inside her. And then your sister - your actual sister slurped your cum out of your mother's cunt. You can hear every lick of her tongue as you watch your sister push her face forward trying to get her tongue deeper in your mom's cummy cunt.

What do you think would happen to you in this situation?

It's clear - your dick would grow rock hard despite having just cum. And you would almost certainly grab your sister by her hips and even though you've only fucked once before in your whole life (and that was five minutes ago) and you barely know what you're doing, you've learned enough from porn to find your way into your sister's sweet pussy. You would absoltely fuck your sister, because haven't you wanted to fuck her for as long as you can remember, anyways and doesn't your 18th birthday seem like the perfect time to express your lust?

And certainly you would fuck your sister harder and longer than you did your mother having just cum (in said mother). You'd give your sister a great, wonderful fucking, fucking her with so much vigor and passion that you make up for your clumsy inexperience and make her cum on your cock, giving you the first feeling of a truly soaking wet pussy. And only then would you cum inside your sister

And while you’re still inside your sister, slowly shrinking in her cum-filled pussy, she would tell you she loves you and would kiss you. “Happy birthday, little brother,” she would say.

So why would you think it would possibly be different for your sons, Zach Jr. and Jacob Jr. in their first time with their mothers and daughters? Of course it wouldn't be.
