I was sucking my boyfriend's dick last night, as I always do, because I can't get enough of having it stretch my throat. He was laying on his back, moaning and grunting, telling me how good I was doing it, which made me want to suck it even more, so I got into a good rhythm, my left hand massaging his balls, the other hand stroking his dick, and my mouth dripping spit all the way down to his ass. The next thing I knew, he took my left hand and moved it down to his ass, and I knew he wanted me to stick my finger in! so with his asshole already being wet from how much spit my mouth was producing and I started massage his asshole with the tip of my middle finger, all while still sucking his dick, then I just barely slide the tip of my finger in and he was telling me yes assuring me that's what he wanted so I gently and slowly kept pushing my finger inside of him and I could tell by the way that he was sounding that he was enjoying every bit of it and he was going to be close to cumming soon, so I finally get my finger in and start gently going in and out massaging the inside making sure I was pleasing his Gspot and devouring his dick, and next thing I know his whole body is convulsing, releasing the biggest load I think he has ever had down my throat and I felt his asshole pulsing around my finger, he came so hard and I felt so accomplished. My pussy was literally DRIPPING. Then he got up off the bed and started fucking me so good from behind until I came all over his dick and he let another load go inside of me. We had discussed me wanting to stick a finger in his ass when he was about to nut before but I wanted him to let me when he was ready and comfortable and knew he could trust me and the fact that he let me do it unexpectedly just turned me on so fucking much that I couldn't even control how violently horny I was. It was an incredible night and I can't wait for him to get off work today so I can get some more. It made me feel so dominant knowing that I was pleasing him so intensely
