Her Cocksleeve

"I forgot my cocksleeve." Crystal turns to face you and as she gets up from behind the bed you see that she isn't wearing her skirt, or panties for that matter. All you see is your big sister's big erection jutting out from between her legs. You've seen your sister's cock before on numerous occasions when you were younger. On hot days where she would stay in the house, she would go around with just her underwear and it would always find a way to poke out, or when she would step out of the shower and forgets to put anything on before going to her room. But you've never seen her cock like this. It pointed almost to the ceiling, standing at full attention as it looks like it's the hardest it has ever been. The blue veins sticking out of it were in contrast to the hot red skin the cock took, making it look like it didn't belong between your sister's pale legs. It looked angry, like all of Crystals frustrations were bottled up in it and it desperately needed release.

"I haven't had the chance to jerk off all day and I'm super backed up." She grabs her balls which have grown to the size of oranges, sharing the same red color as her cock. "So, you see I really need some release." Crystal walks over to the bed and sits down, spreading her legs to present her red angry cock at you. It now points directly up, bumping into her tits which are covered by her black bra, the only article of clothing she is wearing. You step up to her, her dick now stretching up to 13 inches as you get closer, and you kneel down between Crystal's legs. You grab the large package in front of you and the heat is so strong that it's making you sweat. You stroke up and down while Crystal is squeezing her chest but the strokes aren't doing anything. "I need a little more Doug." Crystal's hand grabs the back of your head while her other hand guides her head into your mouth. You open as wide as you can for the intruder and manage to get the head in before it feels resistance from the back of your throat. Crystal strokes her cock as she pushes you closer to her crotch. Pulling her cock out of your throat before pushing it back in. Normally this would do it for her but she is stressed that she needs more.

"Doug, I need to use your ass." You nearly **** on her dick when she said that. You try to protest, but all of your words are blocked by her rock hard schlong which is so warm that it feels like it is burning your tongue. She gets up from the bed and throws you face first into the covers after she pulls her cock out of your maw. Before you could react, she pulls down your pants and jams her fuck stick into you. You regret not lubricating it more with your spit because now the burning sensation in your ass gets worst as she plows her big cock deeper into it. You've never felt smaller compared to your sister before, but as she man handles you, you notice how you legs don't even reach the ground while her feet are planted squarely right behind you. "Oh, I really needed to Masturbate ALL DAY!" Her hands hold yours down by the wrist as she thrusts closer to you, stopping when you feel her large tits resting on the back of your neck. Crystal then grabs your arms, pinning them to your side as she lifts you up then turns around to sit onto her bed. She has stop thrusting into you but now she is using your whole body to stroke herself off. Lifting you up and letting gravity pull you down on her hot and heavy poll. You look behind your shoulder and see her biting down on her lip with her eyes closed. "Good cocksleeve. That's a good Cocksleeve." You big loving sister has now reduced you to her own sex toy. The pace quickens. "I'm cumming! I'm Cumming! I'm CUMMING!!!" You feel your sister's molten hot sperm erupt into your bowls like a volcano. You fall down to the ground while Crystal falls to her side, onto the bed. "Thanks... for helping... me... masturbate Doug." You close your eyes and drift off for a bit. When you open your eyes, you see that you're in Crystals bed as she is on her phone.

"Okay...No problem, I'll let you borrow him." Crystal hangs up and looks at you. "Hey Doug, I have a favor to ask you."

"What is it?"

"I sort of promised one of my friends they can borrow you. I owed them a favor and well she lost her pocket pussy. I asked mom and she said it's okay for you to spend a couple of nights over there anyways."

"Wait, I don't want to." Crystal then gives you the biggest pair of puppy dog eyes you've seen.

"Please Dougy?" You couldn't say no to that.
