He wiggled and prodded before adding a second finger. He started pumping two fingers in my virgin asshole. He fucked my ass for several minutes before...adding a third finger. I was grateful he was taking the time to stretch my asshole slowly. His dick was so huge I was terrified. He finally pulled out his hand and positioned his swollen dick head at the entrance to my never before fucked ass. I pushed and I swear I heard a pop and the searing pain was immense. He waited until my breathing. My pussy soaked my panties.My hands rubbed on my jeans as they came closer together, my futa-sister's cock rubbing into our mother's stomach. It slid up Mom's flat belly. Their tongues danced together, both groaning and whimpering as they shared their taboo passion.This was really happening.“Oh, my,” Mom panted when they broke the kiss. She fanned her face, her eyes wide. “You're really good.”“So are you.” Isidora squeezed Mom's tits. “Maybe I inherited that from you.”Mom shuddered then she. I moved my hands down to her bottom, and alternated between squeezing her cheeks in my hands, and caressing her from upper thigh to waist, sides to the center of her ass.She purred into my mouth, and her hands moved up to curl in my hair. And after a few minutes her movements started to have the desired reaction from me. When my cock started to harden, she kissed me passionately.She rolled off of me and as she held my body I rolled with her, so she was laying on her back and I was resting. I kept my hands on her head while she used her mouth to fuck me and when she stood back up, I got on my knee's and licked at her little pussy best I could in the confines of the shower stall. She had just a light covering of pubic hair and her little clit just barely stuck out from her pussy lips but it was enough to get my lips on. I licked it for a few minutes and she raised one leg to give me better access but it was still just to damn tight in the stall so I asked her to get out and go to.
