Ellen helps you decide

"I wouldn't have pointed my ass at you like this if I wasn't willing to let you fuck it," Ellen says, being nice and dirty.
"Good point."

You push your cock into her asshole, finding it to be tight, but accepting. The blond is keeping loose for you. Thankfully, your face-fucking of Amy has lubed you up quite nicely.

Within a minute or two, you manage to fill her up nicely. You slowly start to fuck her.

"Where was I with the Story again? Oh right. So Amy here is getting pounded in all three holes, while jerking off the other two guys to keep them hard. I'm on my third orgasm- possibly fourth- when I put my foot down on one of Amy's shoes, accidentally bumping it against the door.

The one in Amy's mouth quickly pulls out and the little slut sells me out right away."
"How could I not," Amy says, "They fucked my brains out!"
"So the other two go over and open the Closet Door, finding my clothes and hair disheveled. I quickly try to barter my way out, explaining that I won't tell anyone. They agree- I won't get the chance to."

While you fuck Ellen's ass, Amy continues to ride her while holding her legs back. With her hands free, the blond fondles and plays with Amy's big tits.

"They quickly stripped me down and explained that I wouldn't talk- since I would be part of the same orgy I would be revealing. Nerds sure are smart."
"So did you put up a fight," you ask, "You know- for show."
"A little. I wanted them to think that I was unwilling. The two guys fucking Amy pulled out and made me suck their cocks. Their friends went back to Amy, not leaving her holes unfilled for very long."

You continue to enjoy Ellen's 'forbidden' hole while she tells you that his amazing story.

"So, getting back to the start of this whole thing, how many times did you cum?"
"From them- six times. From myself watching- at least 3."
"You're still not as much of a slut as Amy here, I see."
"World Record," Amy exclaims.
"I'm pretty sure I saw some middle-aged pornstar take like 100 dicks in an hour...but still quite an achievement for you," you say.
"It is just something for you to build up to, Ames."
"I like a challenge!"

Speaking of challenges, Ellen finally cums on your dick, squeezing it even tighter!
