Try to change positions
From Create Your Own Story
You back your ass up into him softly and lean your head forward, so he has to let go of your throat.
"What do you think you are-". He is cut off when you butt bump him backwards so that he falls on his ass. He starts yelling again when you kick your panties off and mount him backwards. You reach behind yourself and line his cock up with your tight, wet pussy. Then you drop down until you take his whole length. You absolutely love being stuffed in reverse cowgirl position. You just lift your backside up and drop it back into his lap over and over. While you are bouncing on him, you feel a finger prodding your anus.
"No!". You exclaim. But the force of you dropping your pussy onto his dick also drives a single segment of his index finger into your asshole. Your guts instinctively tighten around the invader, and it feels like you could break his finger. But after a moment you realize it feels wonderful! You are so wet, too. You continue bouncing on him. Every time you drop, another segment of that finger slides in and again you constrict around it. After four bounces, his entire finger is inside of your butthole. It feels wonderful, and soon you cum hard, pussy wringing his cock and your tight little asshole swallowing his finger.
Moments after your orgasms ends his is about to begin. He pulls his finger out of your ass with a pop and starts to lick it. "I'm going to cum!", he whispers into your ear.
