Take her back to your room
From Create Your Own Story
You put your arms around her and hold her close. "Oh Gwen, you can make me so happy. And I can make you happy too. Let's go back upstairs."
The two of you head back to your room. The bed is still a mess from last night- it smells of sweat and cum. The smell seems to turn Gwen on.
"Maattiiee...." she whispers, "I want to save you from the monster...."
Your cock twitches as her whispers become a moan.
"First you have to find the monster," you whisper back.
You lay back on the bed, and she climb on top of you.
"Where did the monster go," she asks, grinning. "It ran away last night, but we didn't kill it!" She runs your fingers under your shirt. It must be here somewhere.." She starts to pull your shirt up.
You wiggle out of your shirt, and she stares at your chest. She runs her hands back and forth over you, and you feel her hips starting to grind against yours.
"If the monster is hiding, we need to show it something that will make it come out," you respond. She grins again, and quickly peels off her clothes. Before you know it, her panties are falling around her ankles, and she's climbing back on you. She wiggles her young breasts at your face.
"Does it want these?"
"I bet it does.." By now you are rock hard.
Then let's find out!" She squeals as she suddenly pulls your pants down. Your cock springs free and she stares at it for the first time in the light of day. "It looks even scarier when I can see it..." she whispers in a low moan.
Seeing your baby sister stare at you like that, you can't help but feel squeamish.
