My beautiful mom, naked, was straddling my dad's face, which was completely buried under her fat arse. My dad was sticking his tongue into my mother's...tight pussy, and slapping her milky, white fleshy, fat arse cheeks, as he did so. Her beautiful soft boobs dangled down. She was loving every second of it. My mother was busy sucking up and down on my dad's hard cock. It looked slightly longer and thicker than my cock, about seven inches in length.All of a sudden, her mom looked up and saw me. My. I love the way my sister's pussy smells. She gets so juicy. My nose was pressing against her and the tip was covered in pussy juice.I savored the moment, and just breathed in her aroma. Fresh, clean, with just a hint of lilac. It always made me feel close to Susan, made me feel special when I breathed her in this way. Her juices were trickling in anticipation, and I could taste her now. Slowly I peeled her lips open and began to lick her. Teasing and soft at first, but as I became more excited. She understood and we got into position.I had lay down on my front with my ass in the air and she had retrieved some lube from her handbag and we had lubed up.Once my ass and her cock were lubed up she climbed on top of me. I was breathing heavily with anticipation. She guided her hard cock to my virgin ass. I could feel it pressing up against my asshole then I could feel the pressure as she tried to slip her cock into my ass."You really have a virgin ass, don't you?" she said as she tried. I leaned back in my chair.“I'm pregnant.” She pulled a pregnancy test. “That's Britney and me you've knocked up. Lesbians aren't supposed to get bred by a guy. Not the old-fashioned way, anyways.”“And you loved every minute of it,” I said with a smile.A wicked grin cracked her lips. Beyond her, in the hallway, I spotted Courtney and Milena, two members of her lesbian harem. She always had at least a pair of them with her. Vivian had taken to wearing skirts and no panties to always be ready for.
