I kept at fucking her mouth but would back off when I'd feel I was nearing the climax point. No doubt that I was probably leaking lots of precum down her throat. After a while, I went back down to where we started: eating her out, getting my face coated in girl cum, fucking her while deep kissing then moving up to fuck her mouth. I made about 3 round trips up and down her body. Each activity, it was my intention to bring each other right up to the point of climax and then back off. I was partially successful at denying myself, but it was clear, she was enjoying a few orgasms, however mild, in spite of my intentions.
On the 4th round, as I was pumping my cock into her pussy, I was nearing my own climax and decided now was the time. As I reached the tipping point, I pulled out of her sloshing pussy and once again shoved my dripping and throbbing cock into her expecting mouth. What was different this time, was it only took one the one stroke of entering her mouth and my own climax was triggered. Her eyes opened wide and the first shot of my spoo blasted against the back of her throat. Right away I could see the panic in her eyes as she sensed that my cum was going to have nowhere to go but down her throat. After that first pulse, I pulled back just slightly to allow her more room for the sperm that was to follow. I don't know if was the biggest load I'd ever shot in my life, but it was probably the most satisfying to date. My happy dick pulsed and pumped rope after rope of my gooey cum into that little girls' mouth, coating her tongue, filling her completely and eventually being forced out between her lips that were wrapped around my cock.
As I pulled out, I watched the confused look on her face. Being tied up and blind folded, there was no way for her to conveniently and discreetly spit my cum out, which had been her norm after giving head. I gazed at her pretty face and admired how even prettier she always became with the flush that our sex gave her. This time though, her beauty was enhanced even more by the drools of my sperm that were escaping between her sealed lips. Knowing that her mouth was full and it was my cum that was coating her tongue and that she could taste, my heart swelled and I was overcome with both affection and lust. I quickly leaned down and pressed my lips to hers, forcing my tongue between her lips and deep into her mouth. Such a sweet and loving girl, she responded to my kiss in her usual way, slipping her tongue into my mouth, this time coated with my sperm. We battled mouth to mouth, alternately pushing and sucking the cum into each others mouths. It had to be the longest, wettest and intense kiss we'd ever shared.
