From Create Your Own Story
"I think I'm ready for the next level" Siri says as she gets off and Milo, his face covered in her pussy juice "oh my Milo I guess I'm enjoying it too much you look like a glazed donut" she laughs
"No, it's ok it's a sign I did a good job" Milo says Siri starts to lick his face.
"So I think I want to take this to the next level" Siri says as she bites her lower lip coyly "would you like to take my virginity?" She says in as seductively as she can
"Well yes, but are you sure? Not to sound boastful but I'm pretty big for someone's first time. I'd hate to ruin you" Milo ask making sure it is ok to proceed.
Not responding with words Siri straddles Milo's waist and guides his large cock to the opening of her wet virginal vagina. She slowly lowers herself allowing the head of Milo's cock to penetrate her she gives out a light moan never having a cock inside her she slowly. She lowers herself slowly allowing a few inches inside she gives out a light yelp of pain. You see a light trickle of crimson run down the exposed part of Milo's cock, which is still quite a bit.
"Are you ok? We can stop" Milo says in a soothing voice.
Siri bites her lip and takes a breath "No, I don't want to stop" she grunts "you just popped my cherry" a small trickle of tears runs down her face "it hurts a little bit but" she opens her legs and slides down slowly trying to work more of his cock inside of her until she managed to get the entire length inside her "there it's all the way in." She gasps "give me a minute let me just feel it inside me"
"Wow this feels great" Milo says "do you think you can keep going"
"I want to try" Siri whines out. She begins to slowly rock her hips "oh my god this feels amazing" Siri starts to pick up the pace rocking more and faster. She begins to moan. "Your cock is amazing I'm so glad I chose you to be my first" she starts bouncing up and down on Milo's giant cock moaning loudly and loosing all abandon. You work more of your fingers into your own sloppy pussy being turned on by seeing your little sister deflowered. You feel a pressure build until you can't hold it any more and you sundeenly spray a huge amount of female ejaculate it's like a busted fire hydrant, exhausted you stare at your sister and Milo finish fucking. "Oh my god cum inside me" Siri yells.
"Are you sure?" Milo asks
"No but I want to feel your hot jizz inside my tight little body so yes fill me up!" Siri screams as she rides Milo. You can hear the squishy sounds thier fucking is making they continue hard until you see them , both buck and then convulse until they stop and Siri flops down on Milo with his cock still inside her "oh my god yes I can feel your cum inside me" she kisses Milo on the mouth "it feels so warm and gooey" she lays on Milo, his cock now soft slides out " can I aks you something" Siri says to Milo a lite trepidation I her voice.
"Sure" Milo replies
"I don't want to sound forward or clingy but .." she pauses nervous to say what she wants "um can I.. I mean.. if .. maybe... I want to be your girlfriend" Siri finally manages to blurt out.
"Oh I see" Milo responds chuckles
"Oh I see I guess it was silly I'm sorry you must think I'm stupid" Siri looks like she's about to cry.
"Oh no I didn't mean it that way" Milo says comforting Siri "I'd love to date you" Siri gets very happy and makes giddy noises as she repeatedly kisses Milo.

Siri gets pregnant rather quickly it's quite possible it happened that first time. She seems happy and moves in with Milo who takes very good care of her. She visits you often telling you stories about her sexual exploits with him. She keeps him young and he cares for her well even after his death 15 years later.
