Chapter 161 Anonymous Lover:>>21

And as I watched, David withdrew from her pussy. I moved my hand and he engaged the head of his prick at her asshole, and I watched closely as he prepared to fuck her there. She was already half open, but it still took a while for him to enter. She cried out in surprise at his size, her anus stretched by his glans, and he stopped moving to allow her to adjust. I could see her sphincter was tightly gripping the rim of his cockhead, but after a moment she relaxed and he sank full length into her body, until his balls were tight against her. There really wasn't room for me to push my face there, so I rested my head underneath them and watched his cock sawing in and out of her butt. Neither of them had mentioned ass fucking before, and I thought that this was virgin territory for them. Susan was grunting with each thrust and her fingers appeared above my face to play with her clit. Each time David pushed into her she rocked forward and the lips of her cunt opened a little, forced open by the thickness of his shaft in the narrow cloying passage of her rectum. From time to time he pulled out, his cock bobbing free, and I saw that she was gaping open; and then he would place the great purple head at her anus again, and slide it up into her.
