Try to defuse the situation

"Listen, Sarah, I am sorry for sneaking into your room, that was very inappropriate, but I have no clue what you are talking about! I never teased you, not voluntarily! I just tried to live my life, I swear!"

A shadow of doubt crosses Sarah's angry expression, but it is quickly gone. "How am I supposed to believe that? After you've come in here while I was..." she grits her teeth "No, I don't believe you! And now you'll get what you deserve!"

"Sarah, wait!" You scream, but it is already too late. Your sister puts your upper body in her mouth, licking you as if you were a lollipop. Her saliva made it difficult for you to breathe, not to mention the sheer heat of her mouth. Before you could comprehend what was happening, you are out again, a wave of cold makes you shiver as your now exposed and wet body hits the cool air outside.

Vertigo makes you dizzy, as Sarah brings her hand down and jumps on the bed, lying down once more. She keeps you a few moments near her sex, the strong smell of female arousal hitting you once again. he looks down, mouth hanging open, her mind completely taken over by her overwhelming lust.

And then your world becomes an inferno of heat, wetness, and oppressive pressure. She plunges you into her sex, face first, forcing you deep into herself. Panicking, you thrash around, trying to free yourself, but you only add more fuel to the fire, massaging her inner walls in ways that no dick ever could.

You are pulled out of the fleshy cavern, only to be plunged back in. Light and darkness alternate, as your body is repeatedly smashed and crushed against he soft skin and tissue. You feel her quiver and tremble, her climax fast approaching. Then, one final time you are pushed deep inside Sarah, as deep as she can push you. Her inner walls clench and pulsate with pleasure and power, as they batter and **** you as they want. You feel your whole world vibrating, as your sister let out a mighty moan.

When the inferno finally ends, you are pulled out of her quivering pussy. A wave of freezing cold washes over you, as the outside air rapidly cools your body, covered in your sister's female juices.

"That..." she said, panting, "was fucking amazing!"
