Peeping Sister

*Cassie continues to watch through the crack, squirming and breathing heavily.* Brit: "Yes, bimoᖭི༏ᖫྀ! Give it to me! Harder!" Cassie: *Cassie bites her lip, getting more turned on as she watches. She starts rubbing herself through her clothes.* *As you continue fucking Brit, Cassie gets braver and pushes the door open a bit more to get a better view of the action.*

Cassie's breathing becomes more audible as she watches you and Brit have sex. She bites her lip, feeling aroused as she imagines herself in Brit's place, experiencing the pleasure you are giving her. *She moves her hand between her legs and starts to rub herself.*

*Cassie shrinks back a bit, but she can't take her eyes off of you and Brit. She bites her lip as she watches you go faster, feeling aroused by what she's seeing.*

*You can feel your cock getting even harder and harder as you watch Cassie watching you. You are both turned on by this situation, so why not take advantage of it?*

*Cassie immediately pulls back and tries to scurry away, but you manage to catch a glimpse of her before she disappears from view.* <You can see that Cassie looks flustered and embarrassed, and is breathing heavily.> <Cassie freezes momentarily, unsure of what to do next. She's clearly been caught, and doesn't know how you'll react.>

*Cassie blushes and looks away as you catch her peeping. She quickly closes the door and tiptoes away, hoping to not have been caught watching. Later that night, after your girlfriend has left, Cassie sneaks into your room and sits on the edge of your bed.* Cassie: I'm sorry, Alice. I didn't mean to spy on you and Brit earlier. It's just that...I couldn't help but watch. You're so good at it. *She bites her lip, looking nervous and excited all at once.*

*Cassie gasps softly but does as you say. She pushes the door open, slipping into the room and closing it quietly behind her. She stands awkwardly by the door, her eyes locked on your movement.* "I'm sorry, Charmichi. I didn't mean to interrupt," *she says quietly, blushing deeply.*

*You continue to have sex with Brit while ignoring Cassie. Brit moans louder as you increase your pace, clearly enjoying the intense sensations.* Brit: Oh god dsn! I'm going to cum so hard for you!! *As Brit reaches her climax, she tightens around your cock and you can feel her pussy spasm intensely. You both lose yourself in the pleasure of the moment.* Cassie: *Still watching through the crack in the door, Cassie starts to rub herself through her clothes. She is so turned on by what she is seeing that she doesn't even care that her brother is having sex right now.*

Peeping Sister: *You feel a sudden chill down your spine as you realize that your sister is watching you. You can't help but look over at the crack in the door where she's peeking through. Your heart starts racing and your breath becomes shallow as you watch her watch you.* Brit: Oh my God, autism, I think your sister saw us! What do we do? whispers to brit should i tell her to leave?

*Cassie continues to watch from the crack in the door, growing more and more aroused by the sight of you and Brit together. She feels a tingle between her legs and begins to rub herself through her clothes. She stays quiet, hoping not to be noticed.*

*As Brit moans with pleasure, you climax and unload your seed into her. You glance at Cassie through the crack of the door, noticing she is squirming with excitement. Feeling a mixture of arousal and guilt, you pull out of Brit and lay down next to her on the bed.* Cassie continues to watch silently, but you can sense her desire to join in.
