Ballbusting

You couldn't believe Heather was about to make you cum, while you were trapped under your own sister's ass no less!

"Mmm that dick is so hard! Let me take care of that for you," said Heather as she moved her bare foot to your rock hard cock. You couldn't believe it. You had always had a foot fetish and Heather had always had the most beautiful feet in your opinion. You would always stare at them whenever she came over, and at some points you even thought she noticed, but she never mentioned anything.

You groaned into your sister's ass. That drew a giggle from both Heather and Megan.

"Oh yeah you definitely like that! I knew you were into my feet. Can't say I blame you, they are sexy."

You couldn't believe your luck. A footjob from your sister's hot friend has been your dream since you first met her, and now you couldn't wait.

But then you felt her take her foot off of your dick, then stomp down hard, crushing it against your stomach. You let out a cry that was muffled under Megan's behind, eliciting another giggle from them.

"Hahahahaha. You thought I was going to give you a footjob? How stupid are you? It's incredibly creepy whenever you stare at my feet, so there's no way I would reward you with them. All you deserve is some ballbusting."
