Your big sister Cristi has come back home to take care of you now that mom and dad are gone. As she tucks you in for the night you have a heart to heart. I'll always be here for you She says.
There's only one way for me to show you how important family is. Cristi says rubbing you leg. She tells you to relax as she pulls your penis out and strokes you. She opens her dress and shows you her breasts telling you how much she cares for you. As she strokes she tells you what's going to happen. It's going to be my job to swallow it all She says lovingly and does exactly that. From now on your cum belongs to me. I'm glad we had this talk.
The next morning you wake up next to your sister Good morning little brother She says giving you a kiss. She tells you how much she enjoyed last night but that she needs something more from you. You become scared when she tells you what she wants you to do.
Cristi opens her robe and slides you inside of her. She slowly tells you step by step what she's doing as she grinds her hips against you. I love you so much She says, her large breasts in your face. Bouncing up and down she gives you a countdown to cum in her and orgasms as she feels it shoot into her.
You're the man of the family now and I want to try something new Cristi says. She brings you to the bathroom and pulls down her shorts showing off her cute ass. I want you to put it in my butt She tells you, instructing you on how to fuck her like a real man.
Cristi moans turning around and looking at you with love as you fuck her tight asshole. Keep going, Go deeper! She screams cumming on your cock. You cum inside her ass, filling her up. Let me clean you up She says getting to her knees.
You and your sister are making out on your bed. I want the world to know that I love you and you love me She says. She wants to tell everyone that you two are lovers. I can't help the way I feel She tells you. A long conversation of love.
I want something more official. I want you to give me a baby She says pulling off her shorts. She convinces you to fuck her, fill her with cum and get her pregnant. You two will be together forever. Your doing so good She screams cumming. You cum inside her, crossing a line that can never be uncrossed.
