Yes

You look at Mom and reply "Of course mom. I love you too." She gasp with Glee. "Okay let's go to my room but be quite so your sister doesn't get jealous." We sneak over to her room. It is erotic with red flowers and red carpet. Very sexy. "So son come here. Sit." I sit on the bed and look at her. "I want to see that cock of your again. Yank it out!" I take my clothes off and show off my hard penis. "Ooooh it looks lovely." She turns around and slaps her ass. "This big ass is what you must dream about. Want to see mommy's body?" She take off her robe and reveals her lingerie. "The rest?"

She takes off her bra and panties. She exposes her raw hairy pussy. I though my sister's pussy was hairy."You like hairy girls?" She sits next to me in bed. "Come lick my hairy vagina." She spread her legs upwards and grabs my head. She forces me into her all natural clit. "Suck mommy's pussy you dirty boy" she lets me up. "That's enough. Now I just want you to fuck me hard. Have you done doggy style yet? Of course not. I'll get on all fours and you put you dick in my pussy from behind."

She goes down on the bed and spreads her knees. "Come on fill mommas hole." I go up to her and shove it in. "Uhh! I haven't had a man in years! Wonderful!" I thrust against her big ass cheeks. I fuck and fuck her. Her pussy being looser than sisters makes it feel honestly better. Like it's more comforting. As I fuck her the entire bed shakes and she moans. "Now son unlike your sister I'm old enough for more kids. I want you to cum right in me!" I continue to thrust "Sound great!" I fuck her faster and say "Ready for my cum mom?" I hump and hump and then... done. She falls over and smiles. "That you so much son." But of course it doesn't go as planned.

The door slams open. In comes sis.
