Surprised by girlfriend’s sister

You headed straight to your girlfriend’s home after finishing a long day at work. She said no one should be home and that you could hang out for a bit before she got off work. You found the hidden rock with key to her front door exactly where she said she left it and one click of the lock meant you were successfully inside. You put the key back and locked the door behind you. You were tempted to text your girlfriend but chose not to since you knew she wouldn’t text back at this time anyways. As you closed the door the house was quiet and definitely empty. It would have been really awkward if her mom or dad had been home. You knew her sister was away at college so it would be nice to bang your girlfriend around the house once she was off.

You find a comfy spot on the couch and pull out your phone. You enjoy some shorts until you hear a noise from upstairs. (Oh shit! Someone is here!) you think as you contemplate just leaving before finding out who was here but a voice calls down.

“Hello? Max is that you?” The female voice says. It doesn’t sound like her mom so it must be her sister.

“Sorry, Jaz! It’s just me Greg. I was just waiting for Kristi,” you call up the stairs.

“Ah no worries! Almost gave me a heart attack,” she said with a chuckle. “Did you want some company while you wait?”

“Uh sure! Should I come up there or you come down here?” You ask.

“Come up please. I prefer a bit of privacy,” she said. You were unsure about the privacy bit but maybe her parents were due home sooner than you remember. You made your way up the stairs and down the hallway to where her room was the door was mostly closed as you gave a gentle knock. She was not in there as you were confused where she was. You sat yourself on her rolling chair as you waited but she was taking quite a bit. You didn’t really feel comfortable waiting in her room and you begin to wonder if you imagined the conversation. You hear her voice again but it is coming from behind in her bathroom. “Sorry just need another minute and then I’ll be right out!”

You play around on your phone a bit more and then hear the door creak open. Your eyes almost fall out of your head when you see what she is wearing or what she isn’t. “Holy shit…” is all you can say as she bends over and touches her breasts with a seductive smile.

“I’m ready if you are, Gregory~”
