Down Her Throat!

You pinch both her nipples and thrust your hips forward as hard as you can. Your cock goes deeper in her throat than ever before. She struggles beneath you, gagging and ****, spit flying out of her mouth and nose. And just then, you blow your load deep inside her throat.
"FUUUUUUUCCCCKKKK YYYEEEEEESSSSSSS!"
Shot after shot fires right down your sister's gullet and into her stomach. You can feel her throat working each time you fire, swallowing your seed and prolonging your orgasm. You dump one of the largest loads of your life and hold yourself in her throat for several more seconds. She's thrashing back and forth on the couch, your slowly deflating cock still blocking her airway. Finally, you pull out and look down at your handy work.

"Wow, sis, I kinda destroyed you."
Your sister's face is beet-red and she's gasping for air while coughing and ****. Her face is a mess of cum, phlegm and spit. Her eyes are completely painted shut and you are pretty sure she can't breath through her nose.
"That really hit the spot, thanks sis."

You sit her back up on the couch and untie her hands. She pulls her t-shirt the rest of the way off and uses it to wipe off her face.
"Ummm ... no problem, I guess."
You laugh to yourself at the wonders of this place. You never thought you'd ever get the opportunity to do something like that. And now you are in a place where you can do it to anyone, anytime, anywhere.
"I think I need to go get cleaned up", she says and walks down the hall to the back of the house.

You sit down on the couch and play with your spent dick.
"Man, that really felt good. I need to fuck her throat more often."

Your stomach grumbles a bit and you realize you haven't eaten anything in awhile.
"I guess I still need to eat, but hey, a small price to pay for unlimited free blowjobs."
You make your way into the kitchen and search for something to snack on. You find some OJ in the fridge and make yourself a quick sandwich. You gaze out the back window again and don't see Melanie anymore.
"Huh, she must have come in while I was fucking Rachel's throat."

While you are eating, your step-mother comes into the kitchen in her bathrobe and gasps.
"Oh David! Sorry, I didn't realize you were here. When did you get back?"
A sly grin comes across your face while you remember throatfucking Rachel on the couch.
"Oh, just a bit ago. I met Rachel in the living room and decided to make myself something to eat."

Claire stares at you for a moment and then gets herself a glass of water.
"Oh, ok. Will you being staying long or heading back to college soon?"
You take a bite of your sandwich and then reply.
"I don't know. I'm thinking I might hang around a few days, at least. You know, visit with family and stuff."
You know only too well that you'll be "stuffing" your sister's throat again.

"Ok, well, as long as you help out around the house, you can stay as long as you like. Your old room still has most of your stuff in it. We haven't converted it yet. So you can sleep there if you want."
Oh, you'll help out around the house alright. You nod back to her and finish your sandwich.

"Well, I have some things to do. Make yourself at home."
She saunters off back to her room down the hall. You watch her hips swing back and forth and your erection starts to come back.
"Damn, I need some more action already."
