As halftime came there was no sign of Scott and we were losing by three touchdowns. The second half of the game started without Scott and we were per...forming a cheer on the sideline when suddenly there was a deafening roar from the crowd. We finished the cheer and then I was able to turn around and look and as I did there was Scott in uniform just reaching our sideline. He had run from the locker room onto the field and the roar was welcoming him to the game. Within moments he was in front. " ... two..." I let part of it out slowly and concentrated on suppressing the gag reflex for what I knew was coming. " ... three..." I felt him start to press forward as his huge cock-head stretched the opening to my throat and started to slip inside. Not wanting to upset Sven in the least, I concentrated really hard as I felt the initial twinge as my body automatically started to react to the foreign intrusion. I was able to suppress it before my body took over and all I felt was the warm. Sure pussy is great, hell its fantastic but there is just something about the thought of fucking a girl in the ass. Maybe its just the fact of going in thru the out door (so to speak) or a girl being in that submissive position and you know your about to enter where your not supposed to or that you know its a tight tight hole and it just has to feel so dam good, perhaps its all the above and the fact that this is my little sister just ads a whole mix of wrongs which create an irresistible. My boyfriend looked up, his face was covered in my juices and as he kissed me I could taste them. 'I am ready,' I moaned at him and turned myself over. My boyfriend quickly pulled down his jeans and his cock was shiny and red and stiff as a rod. I pointed over to my toiletry bag where there was a tube of lube. He pulled me to the edge of the bed and rubbed my pussy juices around my arse hole. I then pulled my bottom cheeks wide as he squirted the cold lube into me and covered his cock in it. He.
