[MF] My Sister Brings Home a Guy

I wake up to the sound of a bed creaking in the room next to me. The slow rhythm could be relaxing if I wasn’t jealous. Katrina, my sister, has a habit of getting drunk then bringing guys back to fuck.

I check the clock, 1:34am. I don’t really go out to clubs so I never find myself in this situation. It’s been months since I last had a boyfriend. It’s not that there weren’t guys who wanted to, I just never got around to it, there’s always something else I’m busy with.

I hear Katrina start to moan as the movement speeds up. Shit, I can feel myself getting turned on. My imagination starts to wonder, what could the guy be like? Someone tall and handsome with a ripped chest and big dick? Katrina doesn’t look bad herself, we look somewhat similar. We both have a small build with dark hair, though she keeps it short where-as mine is longer. Also I think my breasts are bigger than hers, but she has a bigger ass.

I run my finger over my panties and they’re slightly damp at the crotch. My other hand slips under my tshirt and starts to rub my left nipple.

Katrina gets louder, I can hear her passionately moan as the pace picks up.

I imagine the a stallion of a man fucking my sister from behind, he must be really good to make her sound like this. I rub my clit in time with him pounding her.

Katrina is almost screaming in pleasure now, I can hear loud thuds as the bed slams against the wall. I share my sisters pleasure vicariously, I’m nearing climax.

I cum quietly to myself while Katrina has what sounds like the best climax of her life.

Hopefully now I can get some sleep.

I’m awoken again for the second time tonight as my bedroom door opens. Coming in from the dark I see a large, naked man. He closes the door and comes into my bed. Initially I’m shocked so I don’t react. He just gets under the covers then starts going back to sleep, I think he got the wrong room when coming back from the toilet?

As the shock fades, I start to get aroused. Here is the guy who made me and my sister cum tonight, I have to take advantage of this situation. I slowly move my hand under the covers and reach for his dick. Wow, even soft I’m surprised at how big it feels in my hand. As I begin to stroke it, the thing hardens in my hand.

“Haha, again babe?”, he laughs, eyes still closed.
“Maybe one more time”, I reply.

He doesn’t take any more convincing, he turns around and starts to kiss me. I feel a large hand grab my hip and start to caress me. His hand moves across my thigh towards my crotch.

“Wow, you’re even wetter than before”,’ he says with a chuckle.
“You did such a good job last time”, I reply between kisses.

He pulls down my panties and I shimmy my legs out. His dick is rock hard in my hand as I work it up and down with my hand. He shifts his weight so that now I’m fully underneath him, pinned to the bed. I spread my legs, inviting him in. I don’t think I’ve ever been this turned on. I lead his cock to my sopping wet cunt. Once his tip is in he takes back control by thrusting forward slowly. I’ve never felt anything which was both so delicate and powerful at the same time.

“Oh god”, the words escape my mouth involuntarily as my head leans back in pleasure.

His thrusts begin slow at first but quickly build in speed and force. I wrap my legs around him as more moans are fucked out of me. The sound of my bed hitting the wall fills the air, I hope I don’t wake Katrina.

I moan louder and louder uncontrollably as I approach climax, he grunts as he thrusts harder and harder into me. As I peak, electricity running through me, he also finishes with three slower, but more forceful thrusts.

He pulls out of me and we lie together in the afterglow. I can feel liquid dripping down my leg but it doesn’t matter, we fall asleep in each others arms and it feels like everything is right in the world.

The next morning I wake up alone again, the mysterious stranger is gone. I wonder if we’ll meet again? When I go to the kitchen Katrina is already having breakfast.

“It sounds like you had fun last night” she says with a wink.
