"... Regression fantasies. I always knew I had these weird little desires from the first time I found out you could roleplay with adults on the internet." She says, forced to tell you the truth, but still blushing as she does, squirming in embarrassment as she reveals this deep, sexual side of herself to you. "Don't look at me like that! You think it's my fault I get wet when I imagine myself acting like a little girl in front of others? I didn't choose this! My brain is just... Wired that way."
You feel your erection straining in your pants as you listen to her. "Huh... Well, I didn't think that of you Emily. To be honest, I think that's quite hot. But it's ok, keep telling me about it. After all you love telling me everything about your sexuality, down to your most shameful thoughts. In fact, it makes you aroused when you talk about your kinks and fetishes."
In a few seconds, you see Emily's demeanor go from bitter and annoyed to relaxed and unashamed. She leans back on her bed, grabbing one of her pillows that she firmly lodges between her thighs as she talks. You see her grinding her hips gently on it while maintaining eye contact with you. Her stiff little nipples poke naughtily through her spaghetti strap top, as she grinds against her pillow, cheeks red and breath ragged as she talks.
"When I found out I wasn't alone, that there were plenty of women online who loved to be 'littles' I was extatic! It didn't feel like such a shameful thing and, instead, was just like... A normal thing some girls have. I talked to some of these girls - Told them about the kinks I thought I have... And they were so kind and open about it! They let me explore being 'little' with them, and even allowed me to try being the 'big' while they were being the little!" She gasps softly, blushing deeper and looking away for a moment. " I... I discovered I loved all of it. I loved taking care of 'littles', I loved being a 'little'... Every aspect of it made me very, very wet, and I had to stop often just to masturbate while talking to them." she confesses without skipping a beat. "In the end, wether I'm acting like a little girl, or they are, it makes me shiver and want to touch myself so badly."
You felt about to burst in your pants, having your sister so shamelessly tease herself before you while telling you of her deepest and most shameful kinks... Maybe it was just your teenage arousal talking, but you really wanted to...
