Step-Sister Walks in on you Jerking your Small Cock and Helps!

Imagine this: You're in your room, the lights dimmed, and your hand's a little busy. Suddenly, the door creaks open and in walks your step-sister, her eyes wide with surprise. 'What are you doing?' she asks, her voice a mix of shock and curiosity. You freeze, your small cock in your hand, and she takes a moment to process the scene. You can feel your face flush with embarrassment, but also a spark of something else. She hesitates, then steps closer, her eyes flicking to your hand. 'Can I help?' she offers, her voice soft. You nod, unable to speak, and she takes over, her small hand wrapping around your shaft. It's awkward, but exciting, as she starts to stroke you. You can feel the heat in your body rise, and before you know it, she's on her knees, her lips wrapping around your cock. You're nervous, but she's gentle, and soon enough, you're groaning in pleasure. She takes you deep, her head bobbing, and you can feel the pressure building. Just as you're about to come, she pulls back, her eyes sparkling with mischief. 'Not yet,' she says, her voice a whisper. 'Not until you've made me squirt too.' She takes your hand and leads you to the bed, pushing you down. She straddles you, her wet pussy grinding against your cock. You reach for her, your fingers finding her clit, and you start to rub. She moans, her hips moving faster, and you can feel her getting closer, her pussy getting wetter. Just as she's about to come, you thrust up, your cock filling her. She screams, her body convulsing as she squirts all over your cock. You can't hold back any longer, and you come too, your hot cum mixing with her juices. She collapses on top of you, her body trembling, and you can feel the bond between you strengthening. This is more than just a simple hookup; it's a taboo fantasy come to life, and you're living it."
