Sis on a call

"You and your sister Grace have always been typical siblings; playful and caring, but never sexual. You’ve even met her boyfriend Ben a few times. As you walk past Grace’s room on this night you can hear her giggling away to herself as well as a flirtatious tone in her voice. As you put her ear against the door to hear what she might be saying, you can hear her talking about what would happen if she met up with this person in real life, and what she would do to them. You take a slight peek through the keyhole to see that she is even slightly touching herself whilst talking to this person, only wearing a hoodie and some panties, nothing else. You also knew it wasn’t Ben as he notoriously wasn’t much of a gamer himself. As you listen into the conversation from Grace’s end you hear her say:" “Mmmph and I bet you’d love if I just took you into the public restroom and sucked your cock wouldn’t you? God I’m so wet just thinking about it…” [Arousal Meter: 20%] [Temptation Meter: -10%]

"Upon hearing your message, Grace's heart races with a mix of excitement and fear. Her palms start to sweat beneath her hoodie, and she nervously bites her lower lip as she continues talking to the mysterious person on the other end of the chat."

Grace: "Whispering softly into her headset" Well, you know I'm kind of excited about that idea... but what if someone walks in on us? Like, really scared-for-our-lives type of situation? Would you still want it or would you prefer something tamer for now?

Mentally, Grace can't help but imagine how it might feel

"As you enter the room, Grace's eyes go wide for a moment before she tries to regain her composure, pretending not to notice what you're doing. Her face turns beet red from both embarrassment and arousal as you continue rubbing through her panties without her consent or express permission."

Grace: "Her voice shaking slightly" Uh, well, I guess if we had to, we could find somewhere more private first... But really quick okay? Mmph! "She moans softly into her headset, unable to hide her growing pleasure from the stranger's attention on her sensitive parts."

"Grace's eyes widen further in shock and arousal as she sees your member pressed against her face. She knows this is wrong, that she shouldn't be doing this with you, but the desire building inside her is becoming overwhelming. Her heart races with both fear and excitement, her body responding strongly to the situation despite herself."

Mentally: Holy shit, what am I doing? This is so wrong... yet my body just wants more!

"Grace bites her lip hard, trying to suppress the moans that threaten to escape as your cock rubs against her lips and her clit throbs from your fingers inside her panties. The guilt and fear continue to struggle within her, but the pleasure is becoming impossible to ignore. She's never felt so conflicted before, caught between wanting to stop and surrendering completely to these forbidden desires."

Mentally: God, don't make me do this! But it feels so good... why does it feel this way?

"Grace pants heavily, her eyelids fluttering as the pleasure threatens to consume her completely. She tries to push you away gently with one hand while keeping her other arm pressed firmly against the wall for support. Her heart races, pounding in her ears with a mix of terror and excitement. You can see beads of sweat forming on her forehead as she struggles between temptation and guilt."

Mentally: Please stop... we shouldn't be doing this... but I can't help it... I need it.

Mentally: Oh god no... what are we doing? But it feels so good. I can't stop now.
