You head over to your girlfriends house, letting yourself in and on your way to her room when you pass her younger sister's room, she's laying down on her bed in a short denim dress and some converse. You hadn't seen her since she went away for college and decide to walk in and catch up, she's turns around startled at first but then engages in a conversation letting you know her older sister (your girlfriend) should be home soon, so you can just stay and wait, I mean your practically family anyways been dating her sister forever it seems. You make small talk with her asking how's it been, is she moving back, any plans for then night, etc. You can't help to notice how much she's grown up, you find yourself really attracted to the fact she seems so shy, and almost the opposite in many ways from your girlfriend. She doesn't wear much make up at all, cute outfits but conservative to a degree, but you know she must be secretly hiding the gems. You start bringing up about summers ago, and how you both sorta felt something at some point, but nothing ever happened, she agrees but shyly says it wouldn't mattered and couldn't happen, she couldn't think like that. The more the conversation goes, the more you try to compliment her, and get her to open up more, eventually you have her convinced to show you her tits, hesitant at first she finally unbuttons the dress and shows them off. She still putting up this shy game but you really want her, you have fantasized about her younger sister often and this might be the perfect opportunity to spark things up with her. Besides she can see your hard on in your pants, and I'm sure she's starting to be curious herself. She finds herself losing herself in the moment with you and decides maybe it wouldn't hurt to act on this urge, she grabs your cock and starts to stroke it with her hand, looking away realizing what's has began, she can't just leave you with a hard on and not wrap her lips around it, she decides a blowjob is just a blowjob right? I mean she's been putting up this shy and giggly act, and you tease her about it, but she insists just because she acts shy doesn't mean she is, when she's really into something or in this case someone, its a whole different thing. She drops her dress some, and leans in to your cock as you lay on her bed, and even though she's trying to fight it the temptation and feeling like this might be wrong, she goes in and opens her mouth, she starts sucking you, and touch your hard cock, and you find yourself fully submerged into it, your really into her already. She's sucking you, licking you, talking about how much she loves your cock, your nice body, all those right things, and lets face it she's your girlfriend's younger sister, its already a turn on. As things really heat up, you want to fuck her, you want her to slide on your throbbing member, and you playfully hint at it, and she's all in at this point, she wants it just as much. She slides down on your cock and instant feeling of tightness and wetness wraps around you and you let out a moan, she feels you as she pushes you deep in her and loves it, going straight to bouncing up and down on your dick, her tits swinging all over, so big and so much better than her sister's. She just has that look in her eye that screams fuck me all night long, she's letting loose, dropping that shy act and fully enjoying herself until she cums hard all over your cock, feeling her body tremble, and shake and the moans she's makes are so hot. After a bit she insists on giving you a ride with her big ass in your face, and hell she has a nice ass, better than her sisters too, and you had no idea she had one like that, with the way she dressed over the years. She climbs back on top and rides your dick bouncing up and down those nice ass cheeks she works your dick so damn good, and you let her know that. She often thought her sister was a bit of prude in the bedroom, she just seems so uptight and maybe even the dominant one. Maybe that why you like her younger sister more, more carefree, wild, and submissive just the perfect amount of each. She wants your cum and she's begging for it, where you going to cum she asks, your instant thought was just let it out inside of her, but that likely wouldn't be the best choice at this very moment, you tell her you want to cum all over her pretty face. She climbs off your hard cock and begs for it, she wants it so bad, and you never get to cum on her sister's face, hell your going to blow the biggest load all over her, and indeed you do. She gets hit and plastered with hot thick streams of cum all over her face, and smiling you take a photo, she's lays back and tells you that was amazing, cum dripping off her chin, she better go clean up...Damn, you just fucked your girlfriend's hot younger sister & blew the biggest load you ever have.
