Double Vaginal For Girlfriend

My girlfriend and i were having sex 2 weeks ago. During our naughty time, i had her lay on my lap, and i started spanking her. While spanking, I stuck 2 fingers in her pussy with my right hand while my left hand spanked her. After a few min. I tried something new; with my left hand i slid 2 fingers in on top of my right hand fingers. I had 4 fingers in her sliding in and out of her tight pussy. With the fingers of my left hand in her pussy; i pushed up (toward her ass cause she was laying over my lap doggy style) i hit the right spot cause her pussy opened right up and i slid my right hand fist in. This was the first time she has been fisted, and she LOVED it. Affer about 10 min. I pulled my fist out and started finger fucking her with 4 fingers of each hand. I started dirty talking about it feeling like 2 dicks in her pussy. Now, we are both super turned on about having a 3-some and doing double vaginal penetration. The thought of having 2 dicks in my girl's pussy and having rub against mine while fucking her is so fucking hot. The 2 awesome things about this is that she loves the thought of DVP, and the 2nd is that her pussy normally is extremely tight, and has tightened right back to normal after fisting.
Im a perv and have lots more confessions to make.
