How I fucked my girlfriends younger sister (M/F), fairly long | 2016

Let me give you some background, I’m 23, and I’ve been with my girlfriend, let’s call her Jenny (not her real name!), since we were both 17, and we’ve been living together for the past 3 years. She has a younger sister, let’s call her Sophie (again not her real name!), who is 4 years younger. Her birthday is just before Christmas, so every year we go back to the city we’re both from (we live in another one now) and spend a couple of weeks there for Sophie’s birthday and Christmas.

Just over a year ago (Christmas 2012) we were there as usual and we all went out for Sophie’s 18th birthday, me, Jenny, Sophie and their mum and dad (who are separated). We had good food, some alcohol and just had a generally good time, and all night I kept seeing Sophie look at me, but never really thought anything of it, just assuming she wanted to chat lots as we get on pretty well. When we got back we all went straight to bed, me and Jenny downstairs in the spare room. No action for me there as she was “on” that week, but I’ll spare you the details!

During the night I had to get up to go to the toilet (yeah, I’m like an old man!), so I do my business, and open the door to go back to bed, and I see a shape at the bottom of the stairs. At first I assumed it was Jenny needing the toilet to, but then as the figure stepped towards me I realised it wasn’t her. I feel a finger press into my chest and push me back into the bathroom before the door closes and the light turns on, revealing that it was actually Sophie, completely naked.

She’s about 5’4”, has a cute face with blue eyes and shoulder length straight brown hair. She’s skinny but curvy, with what I now know are 32D tits, and the family big and sexy ass. Before this I’d often wondered what she looked like naked, and what she’d be like to fuck.

So I’m INSTANTLY hard, and go to say something, but she places her finger on my lips to shush me, before dropping to her knees and grabbing the bulge in my pants (I sleep in just boxers) and starting to stroke it gently.

After a few strokes, she grabs the band of my pants and pulls them down to my ankles, before wrapping her hands around my cock. She licks her lips and then slides them over me, bobbing up and down, sucking me like a real professional. I start to moan a bit, and she looks up at me, pulling herself off and straightening up.

I’m confused and think she’s stopping, before she grabs her tits and wraps them around my cock, looking up into my eyes and giving me the GREATEST tit wank you can think of. She keeps a good, steady rate, with a good grip the whole time, and never breaks eye contact throughout. As the feeling builds and the pleasure gets greater I start to moan more and warn her I’m not far from cumming. This seemed to excite her, so she speeds up, sending me over the edge, and making me cum. I shot string after string over her tits, neck and chin, not sure if I’ll ever stop.

As I stop and the last little bit trickles out she puts me back in her mouth again, licking off the last little drops, making sure I’m completely dry.

She pulls my boxers back up, kissing the bulge that refused to go down, before standing up, kissing me on the cheek and then walking out and heading back upstairs to bed. The last thing I saw was her fantastic ass disappear up the stairs.

I’m a little dazed, not really sure what’s happened, but head back to bed, and manage to get to sleep eventually.

Next morning, me and Jenny wake up early and she seems to not have realised that I was missing for very long overnight. As it was just before Christmas, Jenny and her mum were planning on going into the town to do some last minute shopping, and spend some “girl time” together, so they headed out mid-morning. At this point Sophie was still in bed (she sleeps late during her holidays), so they left me watching TV, and just told me to “enjoy myself”.

As they leave my mind instantly turned to the night before, wondering what it would have been like to have actually been able to play with that sexy teen body. I start to get hard again, and start thinking about having a wank. I slide my hand into my pants, and then notice something in the corner of my eye. Looking over, I see Sophie standing in the doorway, leaning up against the frame, showing off her curves.

“What are you doing there then James(not my real name!)?” she says.

“I…erm…” I stumble, not sure what to think with the sexy body in front of me again.

“Wouldn’t you rather be doing something else?” she says as she walks towards me.

“I…well, that would depend on what you meant, I guess…”

“I mean…” she steps towards me “That I want you…” she straddles me before whispering in my ear “to take my virginity.”

My mind (and my cock!) nearly explode… she’s still a virgin? DAMN!

“So, what do you think?” she obviously noticed me looking at her gorgeous tits “Oh, you like those do you?” she says as she leans them in towards me.

I can smell the faint smell of cum on her tits, and realise that she obviously hadn’t cleaned it off and had slept with my cum over her. This obviously drove me wild, so I start kissing those tits, flicking my tongue over her nipples, and starting to suck on them. She gasps, and starts to moan, grinding against my crotch.

I realise that my hand is still down my pants, so I take it out and start to feel her pussy and realise how wet she already is. I start rubbing her clit with my finger whilst still sucking on her tits and I can tell she’s loving it. So I wrap my arms around her and lift her up, placing her down on the floor on her back, with her knees in the air.

Lying on top of her I start to kiss her neck and collar bone, working my way down to suck on her tits again while still rubbing her clit.

“Do you want me to make you cum Sophie?”

“Mmmm!” she moans, nodding.

“Should I eat your pussy?”

“MMMM!” she moans, louder, nodding vigorously.

“OK then.” I say, sliding down to put my head between her thighs. I start to lick her pussy, spreading her pussy lips with my finger and flicking my tongue over her swollen clit. She gasps and moans, clearly enjoying my touch. I start to really go to town, mixing up quick, rapid flicks with slow long strokes and hard succulent sucks.

She starts going crazy, grabbing the back of my head and grinding herself against my face. She starts to cum, bucking into the air and making the loudest cumming sounds I’ve ever heard (Jenny usually tries to keep quiet :().

As she calms down and relaxes she whispers “Fuck me…please.”

“OK, I’ll go get…”

“No need…pill…” she manages to get out.

OK, no need to worry about pregnancy, so fuck it, time to find out what she feels like…

I slide myself in slowly, knowing she’ll be tight and want me to be gentle. She gasps and moans as I make my whole way in (I’m 6 inches long, but have a good, thick girth) and I stop as go as far as I can.

“So you want me to fuck you Sophie?”

“Yes, do it, please!”

I start to build into a rhythm, sliding in and out slowly at first, but building up to a decent speed. Suffice to say, fucking this tight virgin pussy bareback was the BEST feeling I’ve ever felt (me and Jenny almost always use a condom) and I’m loving it. Her face says the same, with her eyes tight and her mouth in a wide “O”.

I manage to last a good 15 minutes going at this pace before feeling a swelling build in my cock.

“I…I’m gunna cum” I manage to stammer out.

“So am I” she says back, before grabbing my ass and pushing me deep inside her as she cums, big and hard, all over my cock. As her pussy tightens and she lets out a big, orgasm scream I go over the edge, and cum, harder than I’ve ever cum before. Spasm after spasm went through my cock as I fill her up and she gasps with each spurt of cum entering her pussy.

“Fuck…fuck…” she says with each breath. “That was amazing!”

“Yes…it was…” I just manage to avoid collapsing on top of her, before pulling myself out and getting up. I hand her a tissue to help with any spillage and say “thank you”, kissing her on the forehead and heading upstairs to have a shower.

As I get out of the shower she walks into the bathroom and says “No, thank you” kissing me on the lips, and getting into the shower herself.

We both sort ourselves out and then continue the day as if nothing happened, watching TV and playing some video games. When Jenny and their mum get back they don’t notice anything and the day went on as normal.

This day hasn’t been mentioned since, and the relationship between me and Sophie hasn’t changed at all, and me and Jenny have gone from strength to strength in ours. I haven’t thought about it since, until we went back this Christmas, and it’s been on my mind since, so I needed to get it out somehow and this has been my first chance to do so.

TL;DR My girlfriends younger sister gave me a tit wank on the night of her 18th birthday, before getting me to fuck her the next day while we were at home alone. No-one else knows it happened.
