Need Help Finding Story

[G414]

I remember reading this story about 2 years ago I believe on Fantasy Feeder but I'm not sure. It basically starts out with two friends talking and one guy says that he is interested in the other guy's sister, who is a volleyball player. He then gives him permission to take his sister out. Fast forward the friend goes and picks up the sister, and when she gets in the car she says "sorry I took so long, my jeans weren't cooperating." and he thinks too himself that her jeans definitely straining but didn't think much of it. They go to the Cheesecake Factory and when they leave he ties his shoe and she walks in front and notices her butt wobbling and small love handles coming out. she then asks him if he think if she is getting fat since she stopped playing volleyball and goes up and hugs him. he says that he feels her belly push up against him. 

thank you guys again. I know for sure the quote I typed is said verbatim in the story.
