For my gal's birthday a couple weeks back, I set the stage for "buttsex and ice cream" a week in advance.
Her: "What are you getting me for my birthday?"
V: "Buttsex and icecream".
Her:
V: "You'll see."
I mentioned it a couple times during the week to keep her wondering. Her birthday came, the party was had, and after the dust settled that Sunday...
V: "Ready for some ice cream?"
Her: "YeesS!"
We had a sex session. After I made sure her other holes were satisfied, I finished in her ass. With my cøck (and load) still inside, I told her:
V: "Now, hold it while I pull out. Then, you are going to keep my load in there while we go get ice cream."
Her: "But..."
V: (before she can finish) "You've had diarrhea before, it won't be a problem. No cheating, either. You're going to show me that you're a good girl when we get home."
Her: "Okay." *clenching ass while I pull out*
So it happened: we got ice cream. While there, she even "upped the ante" by deciding she wanted to order a pizza, sit there and eat it, THEN leave with an ice cream cone.
V: "Check out that hottie! She looks like she's carrying around a load in her ass, too. Should I go ask her?"
Lots of fun.
Once we got home, she went to the bathroom (door left open).
Her: *wet fart and toilet splattering noises coming from bathroom*
V: (in other room) "GOOD GIRL!!! You just graduated to 'buttsex and SUSHI'!"
I didn't need to see that mess.
Man, I gotta tell you... the look in her eyes the whole time?
LOVED IT.
She's had freaky sh¡t done to her before, but this? Owned.
Did I mention that she paid for everything?
