We are 4 college co-eds that like to abuse our asses by inserting big objects. Our favorite is an inflatable dildo. It really stretches the butt when it is pushed in. When it is in, it can be inflated and remain in place because the inflating tube is disconnected. I had it put in my butt and I went to 3 classes, ate a meal and went out drinking for an hour before I had to pee. The great thing about it is I had several orgasms when I walked or moved my butt around while sitting in a firm chair. I currently hold the record by keeping it in place for 10 hours. .
