"Tonights good, lets have a few drinks." Erin said.

After a few shots each and sharing stories from our childhood, Erin whips her dick out.

"Lets compare like old times, 'Little' brother!" My younger step-sister said.

instantly Sarah had my pants at my ankles. "The smaller one will get kicked, just like last time. Right?"

"Well, that explains a lot.." my wife said, "How about I blow the loser instead?" She tried to help me.

"You can do that too" Erin said.

My wife was stroking my fully erect dick. "I'm sorry baby, but her flaccid cock woops your erection's ass, I still love you more, of course." She said, winking at me, as she focused on making Erin's cock hard.

"Mmm that's a fat fucking cock. on a beautiful woman. Even your tit's are bigger than mine, it's not fair." She said, putting the soft cock's head in her mouth, which was most of that she could muster.

Sarah also began to stroke and help Erin's cock get hard.

At last Erin's dong had reached it's final form, at 11.5 inches in length. Basically the whole ruler.

Mine still erect, at a cool 8 inches still.

Elizabeth began to suck my cock, "Loser gets a blowjob". my wife said.

"That's right baby." I said, placing my hand on her head.

WHAAAAAAP.

Sarah had punched me in the balls from behind, as Erin came. Of course.

I came instantly, It was a good punch. My older sister was fairly athletic.

I slowly dropped to the floor, with my cock still in my wifes mouth, she was cleaning my cum off my cock.

"Mmm your cum is always, tasty baby. I love you."

"Sorry, just keeping up tradition, plus Erin loves it." Sarah said.

"He might be in pain now, but i'll make it up to him. Plus he came too, more so than usual." Ellie said.

They got me a towel and some ice for my swollen balls, as Erin ate my wife out and Sarah worked on Erin's cock and balls, trying to tease as much as possible. Even playing with Erin's pussy. Something that never happened.
