Her moans were long, and ending in purrs that made his mind melt. Finally, her back arched and her tightness gripped him in a pulsating vise as the sp...asms that ripped through her milked his seed. He let them loose, with an intensity that was beyond compare…seemingly cumming for several minutes deep within her. He stayed inside her until his cock softened enough to slip out of its own accord, bringing his pearls and her honey with it. Her face was something he would never forget as he studied it. Smelling it, Scotty let out another bark of excitement.Biff chuckled. He stood behind his sister with a tablespoon and the opened can of dog food. He spooned out a large portion of the dog food and smeared it on Gail's pussy and ass crack. He smeared more of it on her inner thighs. The thick stuff clung to her pussylips and little pieces of the food fell off, spattering on the carpeted floor."How's this feel, Sis? Bet you love it!" Biff said nastily. He parted his sister's cuntlips and spooned. Playing with her ass she said "OH YES" "finger my ass hole". She was getting all into it. He had two fingers in her ass and I could taste all her sweet juices run down my face. I could feel his hard cock poke me in the top of the head. I tilted my head farther back and there was that fat cock of his. I stuck my tongue out and licked the head of it, his pre-cum was sweet. As I opened my mouth wide he slide it slowly deep into my throat. His soft shaved balls were slapping me in my forehead. This. I asked mom a few more questions about the sperm squirting inside her and she told me how men put their penises inside pussies. She said it feels really good. I asked mom how many men had squirted inside her, she blushed and then said she would not tell. I asked again and told her she was teaching me and then she said about twenty five. Again playing dumb I asked if she got pregnant each time and she said no that she used a birth control pill. I asked mom if it felt good and she said it feels.
