Fortunately I had enough knowledge of the female anatomy to accommodate her wish with my thumb. Beyond that, I can’t be sure what I was doing, to be...honest it was all a bit of a daze. I moved my fingers and thumb with no great plan whatsoever, hoping that I was doing something right. If nothing else I was only too well aware of her hand closing on my shaft as her pussy grew tighter and tighter, until I could barely move my fingers. By then I’d added a third finger, or at least that’s how I. I was in heaven "NO WAY!" I said... "Do you care?". Never being the type to care about what I did she said "No, but Lauren is my best friend". "It's just a date" I replied. By this time I was hanging out with girls every day, but 16 year olds, nobody I admired as much as her though. She didn't seem to care, but I could tell she was floored by the fact that her best friend wanted to hang out with her little brother! Nonetheless, she passed over a peice of paper, it was Lauren's cellphone number. He then told her "Now suck me hard. Run your tongue over that cock as you suck. I do like that a lot." He kept shoving the cock in and out gagging her as the tears ran down her face and slobber down her chest. Sometimes he would hold her head tight to him as his cock was deep in her throat and she gagged hard. Then he would let her up and the spit would pour out of her mouth. He fucked her mouth for ninety minutes and her tits were covered in her slobber. He kept working his cock deep then. She whispered……..”Ata ki? Chhado amake. (What is this? Please leave me.)” I just was continuing my job. I kissed on her juicy lips and squeezed her boobs. Wow! That’s nice, so soft and big. I whispered……” Moni ami tomake chudbo. (Moni, I want to fuck you.)” She replied……..”Na Na keo chole asbe. Amar bhoy korchhe. (No, someone may come. I am afraid.)” I don’t answer her just continuing my job kissing and licking her lips and all over her face. Now she was also getting hot. She hugged me tightly.
