She forces herself in your mouth

Zoe kneels down to your level before you notice. Unnerving how she's still taller than you. She gets closer to your face, making you get away from her and the situation even more uncomfortable. Your sibling doesn't care though, pushing you back to the ground. Your legs try to fight but she gets on top of you with relative ease, her greater weight immobilizing your smaller frame.

You can sense her limp dick sloppily rubbing against you. Her massive rack rests against yours.

"I did what you asked, now turn me back." The taste of her 'thing' still lingers on your tongue.

"Just let me do a little something first." She lowers her head and tries to touch your lips with her own. You instinctively veer your face to the side. Just avoid her.

"I don't want to do that." This feels so uncomfortable. You now have a ping of sympathy for girls that get harassed like that.

"You're such a selfish little bitch Lucas. It's my cum you got in your mouth and I want to taste it..." She grabs your cheeks and turns your soft face to hers. You try to keep your lips tightly closed as Zoe forces herself on them.

A sudden gasp of pain. Did she just punch you in your ribcage? Your sister tries to kiss you again and this time you let her. It's wet and her tongue feels slimy. It's not like she's trying to really kiss you, more like lick off whatever cum you still had in your mouth. Zoe's always been kinda hot and the kiss is not the worse one you've ever had, but you can't help but feel grossed out. It's because she's your sister and of what she's done to you... right?
