Diana was looking for an excuse.She wasn't ready to reveal the fact that she wanted to seduce his sister, too, not being sure how the red-blooded lad ...ould react to such distaff desire.She didn't want her son to think she was a lesbian or a deviate or a pervert – which was a different matter from simply being a mom who sucked off her son.The innocent and naive boy might well think it sordid if he knew she wanted to suck his sister, too."My prick is big and hard, Mom. We can do it right now!". I readjust the growing bulge in my suit as I drive to get more comfortable. He trails like he is stuck to me, and is out of his car first as I park in my driveway. The house is empty; neither parent will be home until late. A drink of water for his dry mouth in the kitchen, a short tour of the house, and he stumbles into me as I open the door to my room.Feminine and lacy with posters on the wall, he sees what he sees at home or at his neighbor's house, a typical teenagers room. I have one item. As she looked at me she whimpered, “Oh god, Matt. Fuck, you feel so good. You’re so fucking hard. Ohhhh, I want you.”She let out a soft breathy moan and closed her eyes as he slid into her for the first time. With his initial thrust he sank about half of his cock into her. With his second she took all 8 inches. He continued thrusting and began kissing her. She leaned her head forward and bit his shoulder, then turned to look at me while he pushed deep into her.“Ohhhhhhhh fffffuuuuuccckkkk,. Bending my knees looking her in the eye through the mirror I smiled and asked, “Are you ready sweetie?”She looked back at me with that smile that just wouldn’t go away, “Oh, yes Daddy go slow and please be gentle this time, that is, until you’re all the way inside of me then pound the shit out of me.” I pushed the head of my cock between her cheeks. Slowly and gently I continued delving my head at her resisting O ring of her anus. Its reluctance finally gave way to the pressure of my force.
