I am your girlfriend and I just got home from shopping. I'm very enthusiastic and tell you I haven't bought much but that I have a surprise for you. I've noticed you literally can't stop looking at me when I'm wearing jeans, so I bought a new pair which I think you'll love. Let me show you how they fit me... I can tell by the bulge in your pants that you like them a lot!
You're so hard, unfortunately I don't have time to have sex since I have to go out again... But I don't want to leave you with your balls full of cum. You could jerk off to me as I showcase my new jeans. Fair enoug...

You agree and I give you a quick JOI with a cum countdown that has you cumming all over my jeans-covered ass. Look at that huge load! I'll definitely be wearing these a lot!
Now I have to quickly clean up this mess and go out with my friends. See you later babe xx
