Enter her room

Emily opens the door and lets you into her room. As you enter, you try to look for where she could have put your cage, but its nowhere to be seen.

"So.. anything" Emily says from behind you. "You're gonna have to do so fucking much to ever be able to make this up to me, you sister loving freak"

You turn beet red, as you realize that your sister has realized that she has an edge on you, and her usual teasing side has come back.

"So John, what do you wanna explain to me first. The fact that you want to fuck me or the fact that you want your cock to be locked up?"
"Em.. please", you reply, knowing there's no way you could ever explain any of this to your sister.
"And how long have you been stealing my panties?" she continues, now with a mischievous grin on her face. "These are supposed to be for Eric's eyes only you know", she says, mentioning her boyfriend. Your cock twitches a bit, thinking about your sister having sex. "Is my little virgin brother so desperate that he has to turn to his sisters clothes to feel close to women?"

Your heart drops as she utters that last line, as it cuts through you. Yes you are a virgin, and the fact that your younger sister isn't is something that you definitely spent a lot of time thinking about. You haven't ever been good with women, or people in general for that matter, and since you've been staying home these last few months, you've isolated yourself more and more.

Your sister can see that you were visibly hurt by that last line. "I'm sorry John. I shouldn't have said that." She looks into your eyes, and your can feel that she really means it. You and your sister has always gotten along well. She has been the only women you have been able to easily talk to, and yet you decided to screw it all up today.

"But you did jerk off to me, you perv. And I will not forget that" "I did know you were a perv, it's not the first time I've heard you jerk off" she says, smirking. "But I didn't know you were this much of a pervert." she says, fishing out the chastity cage from her pocket.
