Alison's bad luck/bed/Jack awake
Seeing Jack sleeping, and much like you, without pants, only wearing his pajama shirt and a pair of briefs. It seems like he thought it was a good idea to sleep without pants, just like you. Your eyes were drawn to his underwear for a moment, it had some sort of cartoon print, you look back to his face, realising he's sleeping.
Your face warm and a smile form on your face with the thought of seeing his dick, it is right there, only covered by his underwear.
Moving closer to Jack, you bring your hand to his shoulder and gently nudge him.
"Jack" You say, his eyes slowly open before he turn to look at you. Seeing that he's awake you smile and say cheerfully "good morning".
He yawns and sits on the bed, rubbing his eyes before replying with a "morning sis"
"Why are you on my bed, did you forget this is my room?" You ask.
"Uh... no..." He says clearly nervously "I... I just wanted to sleep with you because you're so cool" He looks up to you with his big eyes, trying to show his cutest expression.
You didn't know that your brother could be this nice to you, you remember him being annoying in the past, but something about him looks different. Maybe it's because you went to college for the past year, this is even the first time that he sleeps with you. "Okay, okay, there's nothing wrong with you sleeping with me."
Jack smiles "thanks sis, I really like sleeping with you"
You smile and look away for a moment, you have no idea why you're feeling this way about Jack, it's not like you were close before, so maybe this is good. When you look back at him your eyes are drawn again to his bare legs again "Uhm, Jack... Where are your pants?"
"I took them off" he answers gleefully. "I saw you without pants, so I took my pants off too"
You look at his underwear and to what appears to be the shape of his dick in his briefs, is he getting hard? You can't really tell by looking. But then you realize, he's also looking at your legs!
