Oh God, that was hot. She was just sucking on your cock and didn't even know it was yours.
"It doesn't even taste rubbery." She starts to strip. You know that this is headed for a test run. She lays back on her pillow and grabs a bottle of lube. She starts rubbing her pussy with lubed fingers. Inserts one and then two fingers. Then lubes the head of your cock.
It's thick enough that she can't just drive it home, so you watch painfully aware as she starts to ease it in inch by inch. She finally gets the balls to touch. You're all the way inside of her. Oh, how nice it would feel. Her tight pussy gripping your huge cock. It buried inside of your own sister.
You wish that you could feel that. Suddenly you feel every inch of the inside of her pussy. God, that is amazing. It's almost too hot, it's way hotter than any massage gel that you've jerked of with.
She slides it out a fraction and then back in. "Oh fuck. I'm never going back to any other dildo. If this dick had a man attached, then I'd never stop fucking him." You want to cum already hearing her say that. "Um, only one thing would make this better." She reaches back into her night stand and pulls out a battery powered bullet.
She coats it in lube as well and lines it up with the hole in the back of your dick. As it touches you feel something different. She slides it in with one swift motion. You feel your sphincter open and accept something into your ass. You gasp in surprise and terror.
Then she turns on the vibrations. "Oh fuck," both of you say at the same time. Every young guy has tried at least a finger in the bum before. A gay check as the rest of your friends joked. You hadn't been to thrilled with those results, but holy hell... this time.
She starts to fuck you faster and faster. Thankfully she only makes it a minute before she starts to convulse on your cock, because you can't hold out any longer. You begin to cum. You can tell how powerful it is because your normal small spurts into a dirty towel or the toilet never go like this.
It's cuuuuuuuuuuuuuuuuum, and then cuuuuuuuuuuuuuuuuum, and then cuuuuuuuuuuuuuuuuum. Oh God, that feels great. You've never had a release like that. You open your eyes to see Mia spread out on her bed panting.
"Oh, you even cum like a stallion." She has turned off the bullet and slowly slides you out of her. "Time for you to join the stables." She puts your dick still dripping cum into the nightstand. As she stands up your cum starts running down her leg. She scoops some for a taste. She looks very pleased with the results.
"My new best friend," she had a she heads to the shower to clean off. Your cum is still leaking from her pussy and then you feel a bit. Is it possible to get your sister pregnant from cuming inside her even when your dick isn't attached?
"I wish that my cum couldn't get Mia pregnant." Oh dodged a bullet there. You have your towel in your hand for cleanup before you realize, as long as your sister does all the work you'll never have to clean cum out of a towel, sock, pillow case, or your bed ever again.
You try to figure out what to do with your cock, but can't quite stay awake. The next morning you rouse on top of the covers. You are coming out of the sexiest dream. Mia's tits are bouncing as she rides your cock to an amazing orgasm. Your both so close. You look through the wall and realize that Mia has decided to start her day right.
She is indeed riding your cock. Based off the whimpers she isn't far from finishing. Her head is down low in concentration. Her sons are flat on the bed and she is grinding her hips forward and back rocking your thick cock inside of her. And then her orgasm kicks in.
This time your aware enough with less excitement to take stock of what's happening. Her pussy has clenched even tighter on your cock. The rush of her juices is forcing them around you and down your balls. And then you begin to fill her overflowing so that your own cum jobs here and pools up on the bed around your balls.
You want to just pass out again and go back to sleep after waking up to getting fucked. Even though your dick isn't currently attached, you still get all of the fun while your sister does all of the work. You feel your cock get extremely warm again and have to look. Mia is waking it off in the sink. She kisses it before putting it into the drawer.
Then you both hit the showers and head down for breakfast before school. Thank God it's Friday. "Hey squirt." You almost choke on your orange juice after watching her squirt on your cock. Twice.
"Her Mia."
"What's going on with you. You look beat little bro." You don't even have the energy right now to banter back and forth. "Did you sleep at all?" Then the concern is gone. "Did you have another monster dildo in your room and start up all night playing with yourself?"
"I wasn't the one doing anything," you blurt. Oh crap, the look on her face. She is red as all her out and quickly turns toward the fridge.
"How late do you work tonight? The girls are coming over for a sleep over since Mom and Dad are gone until Monday. I think we're going to order pizza tonight, so I'll get you a Supreme."
"Cool, but I'm off tonight. I'll probably hang out in the garage so that I don't crap your party."
"What? You never have a Friday night off. That's perfect though. What are you going to cook us instead?" She looks at you all hopeful.
"Really?" You are the cook of the house. It's something that you do enjoy and your actually really good. "What do you want?" She knew the drill, no specific foods can be requested only the type of food.
"Pasta. Oh, pasta and something grilled. You are awesome little man. Send me a shopping list before luch and I'll pick it up on the way home." She comes over and pulls you into a big hug. You can't help but think about her breasts bouncing this morning as she was unknowingly riding you.
"Yeah, sure. You owe me though," you mutter.
"Tell you what, I'll pay up in full. Tonight. I'll have the girls bring their swim suits and we'll have pool time while your grilling. I'll even have them wear something skimpy. Give you something to think about tonight with that dildo keeping you up all night."
