Best friend’s sister [MF]

After a long year, finally having holidays is exciting. I head over to my best friends house. It’s a little earlier in the morning than he might be like, especially during the holidays, but the weather’s too good to not go to for a swim. I get to his house, and ring the door bell. I know he told me his parents are away, so hopefully he’s up, and actually answers.

Even just before 9am, it’s already starting to get hot, and I’m very keen to get in the water. Several seconds pass, and there’s no response, so I ring the door bell, again. I see a shadow approach the door; it’s a fair bit shorter than I was expecting. As the door swings open, I see her. His little sister.

She looks like she’s just got out of bed. She’s wearing a white spaghetti top, with a small red pattern, and a short navy blue skirt. barely covering her skinny legs. He hasn’t really talked much about her. The first time he told me about her, she had just come back to home after turning 18. He didn’t seem to want to talk about it, so I didn’t ask.

“Hey, can I help you?” she asks in a sweet tone.

I pause slightly, taking her in. I have to admit she’s absolutely gorgeous. Her medium length blonde hair falls naturally onto her chest, in direct contrast with her porcelain complexion, and her dark eyebrows. Her lips are full, and she’s got a couple piercings. She’s not wearing any make up, other than some mascara, which really accents her deep green eyes.

“I’m here to see Mark” I say flippantly. “You must be his sister.”

“Anna” she says, as she smiles a little bit. “He did say someone might be popping by.”

A few seconds pass by in silence, as we just look at each other. I must be almost a foot taller than her. I have a wide frame, and have been hitting the gym for the last 6 months. As I look down to meet her eyes, I can see she’s taking me in, but I try and play it off.

“So…you going to let me in” I say trying to get her to stop ogling me.

“Of course” she replies back flatly. “Mark is still asleep. He had a big night last night.”

“Sounds like him” I say knowingly. “We’ll have to wake him up then.”

She opens the door, just enough for me to get through. As I enter, she accidentally brushes in to me.

“Oh sorry” she says. “I’m still waking up.”

“It’s not a big deal” I say, not really thinking much of it.

As she closes the door, she says “we’ll just have to go upstairs to his bedroom.”

“I know. I have been here before” I say slightly too condescendingly.

“Jeez, I am just waking up” she retorts.

“Oh, I couldn’t tell” I reply, doubling down.

She rolls her eyes at me, and then smirks “his room’s this way.”

Even just walking normally, I find it extremely hard to not get lost in her hips, ass and legs. As she starts climbing the first stairs, her tiny little skirt bounces against her ass. She’s not wearing any underwear. Her ass is just as pale as her face. God I bet she can feel my eyes on her. She’s my best mate’s sister I’ve got to look away.

I start climbing the stairs too. Their house is the largest on the street, high ceilings, and the staircase ascends quite sharply. I look up again, and her bare ass is on display. I slow down my pace, trying to control where I’m looking but it’s no use. I’m several steps behind her now, and I’m sure she can feel the heat of my eyes taking in her tight little ass. As she gets ahead, I can see the outline of her tight little pussy. Her little pink folds, picturesque between her pale cheeks. I bite my lip, and close my eyes briefly, as the image of her spread for me races through my mind. I bet she tastes amazing, her little pussy ripe before her morning shower, all mine to enjoy her sweet nectar. My body’s responding to her, much faster than I thought it might. I feel a little guilty, she’s my best friends sister. I can’t think like this right now.

As we get to the top of the stairs, she waits and looks back at me. She gives me a satisfied look.

“You know the way from here, don’t you” she smirks at me.

I pause for a second. She probably just looked at me like that because I was smug before. There’s no way she knows just how much of her I’ve seen. That would mean she wanted me to see it. To see her in all her natural splendour.

She doesn’t even wait for a response. “I’ll catch you later” she says, as she puts her hand on my arm, and smirks to herself and then walks off.

Her room’s just before Mark’s. She walks ahead of me. I can properly feel the bulge in my pants now, and I’m not sure I want to walk incase she looks back again. I try and adjust myself, but my cock just hardens further. It’s been far too long since I’ve had a release, and my cock is throbbing now because of her. I watch her as she walks off, entering her room which is just next to Mark’s.

I wait for a few minutes, trying my best to get my cock to stop misbehaving, and just lose this boner. The image of her is etched into my mind, and I’m really not able to stop my desire from showing. Waking up Mark with an erection would raise way too many weird questions. I wait and just enjoy the view from the second floor. Seeing the beautiful jacaranda trees that soften the skyline towards the city, but I can’t think about anything else than his sister’s gorgeous little pussy.

I know it’s futile, so I just decide to knock on his bedroom door and hopefully things should chill out by then. Approaching his room, I see his sister has left her door open, but I do my best not to look in. I knock loudly. Mark’s a deep sleeper, and it’s going to require an effort to wake him up.

The first few times I bang on his door, don’t really do much. But after yelling his name a couple times he finally wakes from his slumber.

“Shut up” he says. “I’m trying to sleep.”

“I told you, I’d be here, you lazy fuck” I respond. One of the perks of being best friends is that basically anything goes.

“Shut it dickhead” he retorts. “You can go and have a swim and I’ll join you at a reasonable hour.

Although I’m a bit disgruntled he doesn’t want to keep his word, it’s not worth the risk of opening his door. He could be in any state. I walk back towards the stairs, again trying my best not to look into his sister’s room. She can’t know what’s been running through my mind.

As I get down the stairs, and wander outside, I realise just what a great day it is. The weather is perfect for soaking in the sun, and chilling around the pool. If only Mark wasn’t so lazy.

The warmth of the sun on my skin feels amazing. Their pool is just the right temperature, and I can see myself swimming all morning. I grab the sunscreen, and take off my shirt. Looking at myself in the mirror, I realise I’m in the best shape of my life. I start spreading the sun lotion all over my arms, pecs, abs and back. Trying my best not to miss any of my upper body. I apply it to my face and neck as well, and then enter the shallow side of the pool.

The chlorinated water comes up to my waist. It’s so refreshing. As I revel in using my best friend’s pool, I look up. There’s his sister. In a tight bikini, walking toward the pool.

Her bikini is light pink, and barely covers her. As I stand in the pool, my eye line is at the same height as her hips. Without even thinking I’m staring at her, seeing the tight fabric against her, her little folds creating a gorgeous outline. Somehow seeing her more covered up, makes me go crazy. I can’t believe how much I want my best friends sister.

I scan up, and see just how tight her body is. Her flat little stomach, completely juxtaposed with her ample tits. I almost wouldn’t have believe they were real. They’re so perky, and perfectly shaped. Hard to believe that this is real, even if she is just 18.

She approaches and notices the sunscreen all over my torso. “Hey do you mind doing mine as well?” she asks in a cutesy tone.

I’m already wet, and in the pool. But she does need help not getting burnt.

I get up, and barely dry myself off, letting the water drip down my body.

“Where do you need help with?” I ask.

“Mainly my back” she says, whilst smiling again. “I really appreciate your help”

Getting behind her, her hair looks so soft, and she smells absolutely amazing. As she brushes her hair to the side, exposing her back, some of it hits me and feel it softly run against my skin. I grab the sun lotion, and almost fill one of my hands, having to squirt the bottle several times, as it’s getting towards the end of its useable life.

I rub my hands together, and then onto her back. Her skin is so soft underneath my hands, and I can feel her breathing as her back naturally expands in and out. A few of her little blonde hairs on her back glint in the sunshine, as I make sure I massage the sunscreen into her back. I’m feeling so much tension inside of myself, and I know it might be coming through my hands but I can’t help it.

She undoes her bikini top, as I make my way lower. I make sure I don’t miss any of her, as my hands explore her back, covering her with a good layer of sunscreen.

“I always miss the sides of my body” she says. “Do you mind helping me?”

I just nod as I grab some more sunscreen. She lifts her arms forward, and her bikini top almost comes off. She reflexively covers her chest with her hands, whilst still keeping her arms raised. She just grabbed her bikini top in time, keeping herself covered.

Moving slowly up and down the side of her torso, my hands can’t resist pressing a little harder against her. As I get higher, I don’t want to miss a spot, and feel some side boob. She’s so soft but the very small part of side boob felt even nicer than I could have imagined.

“Thank you” she says, as I finish up. “I’m just going to lay down and let this soak in,”

She lays face down, still not tying her bikini top up, as she puts her headphones in and listens to music. I see her boobs get accentuated under her weight, as she closes her eyes and takes in the sun. Her legs are together, and her light pink bikini bottom is riding right up her ass. The outline of her little pussy lips are so clear, and there’s an obvious, but small, wet patch in her underwear. This makes my mind drift further, as I feel my cock throb yet again.

Now I’m starting to think that maybe she’s feeling it too. I start to wonder if she knows the effect she has on me. And if she’s feeling anything too. Surely she can’t be, it would be so wrong.

I jump into the cold water, allowing it to wash over me. All this tension is bubbling up inside of me, and I know I need to release it very soon. I just enjoy the pool, doing a few laps to release some energy.

After a bit of time, I notice she turns onto her back. She didn’t really apply much sunscreen to her front, but she seems content just as she is. She relaxes a bit more, and lets her arms drift by her side. As she moves a little bit, her bikini starts slipping, ever so slightly. She’s still fully covered, but the bikini top is riding down her boobs, showing off her perky round breasts. The fabric is moving against her, and I can see her nipples getting hard.

As I snap back to reality, I realise I’ve been looking at her. Hopefully she hasn’t noticed. Just as I try and regain my composure, I hear something.

“Hey!” It’s Mark. “What are you doing in there?” he yells and then pauses.

Oh fuck. He’s just seen me checking out his almost naked sister.

“It’s too flat, get ready for some waves” he yells, as he runs up and jumps into the pool, the water crashing and forming several waves, he just misses me with his neigh on belly flop.

Without thinking I splash him, getting him back for covering me with water. Not amused, his sister leaves shortly, and I do my best not to look at her as she heads back inside.

I hang with Mark in the pool for a long time. It’s fun just shooting the shit, and catching up. Hearing about his Christmas, and solidifying our plans for NYE. It’s great to be able to spend time with my best friend, and I feel very fortunate, as we have a ridiculous NYE planned.

After staying in the pool for ages, I’m starving. Mark says he’ll go out and grab some food for us, and he’ll be back shortly. I thank him for being a good friend, and head up to the upstairs bathroom to rinse off.
