You two wake up

The next day you wake up to sis dreaming. She moaned in her dream and I shifted a little. The bird were twerping out side and it was around 10. "Hey wake up sis" she gets up and rubs her eyes. She yawns and looks down. "Are we adults now?" She giggles and gets off my cock. "I'm gonna go take a shower." She gets up. She goes to stand and she wobbles. "Whoa my lady parts feels so weird." She walks off.

Later in the day we are watching tv. She is playing on her phone away from me. "Hey bro I just read that a slit is called a pussy. And your thing is called a dick." She reads on. "That's good to know." Orgasms start playing from her phone. "What the heck! I just discovered something called 'porn'. It's so weird. Those girls are so much older than me. And they have bigger boobies." I move over and sit next to her. "If you watch some of that porn can you learn and show me late" she bites her lip. "Sure will bro."

Later that day she comes into my room with a new technique.
