She apologized and told me she needed a man cock to fuck her dripping wet cunt and would be back in a few minutes, as she lived close she returned wit... her brother who was smiling from ear to ear, he started to ask me some horny questions like did I get hard watching his sister fingering herself to which I answered yes, had I seen a really nice man cock to which the answer was no. She laughed and said he would love to show me his, Whist taking her hand and rubbing his cock over his jeans I saw. Her pussy is so soft…I grab it eagerly but gently and use my whole hand at first to encompass it. Right now I can tell she is so high on pleasure that she doesn’t know what to do so I quickly grab a chair and position her right on the edge so I still have access to the pussy.Then I go to work, hungrily I rub and tease and tempt her spot with my fingers and she has to bite her lip not to scream out. I trace tiny kisses from her ears to her neck and give gentle licks as I go. I can feel the heat. Then I dipped down, taking more of him. I developed a rhythm of small pussy kisses and deep, deep plunges. My baby was groaning out the whole time and he started slapping my ass on every down thrust. "Fuck, baby," I yelled. "Harder, baby, keep going, fuck." He smacked me and slapped me and I started screaming out. My god, the combination of his dick so deep in me and the spanking drove me wild. I was only my body. There was nothing else in the world. Shit, shit! "Baby...do it....harder," I. She shifted her position then - got onto all fours. And I started to hump her throat. I held her head down tight against me & thrust vigorously, quickly & steadily. Scowling at myself in the mirror over our dresser at the foot of the bed. She started gagging and choking and coughing, spitting up wads of goo & snot, stuff shooting out of her nose against my pubes, back-splattering her face, etc.It didn't take me long. I was pretty spun up & horny, as I said. I didn't tell her I was about to nut.
