Sarah masturbating

He went to his sister's room and found her masturbating and cumming all over the room, with her big and thick cock. Adam could not believe his eyes when he saw it, but was unable to say anything, or move at all. His senses were already filled with with a strange longing. He did not know what it was, and that meant him he wasn’t supposed to feel this way.

Seeing his sister covered in her own cum, furiously stroking her cock while fingering her pussy made his mouth water.

He saw the pure pleasure on her face, and the desire to feel more of it. He wanted to give her what she wanted. He wanted to pleasure her, but his still-self-aware side held him back. This new desire… he felt the same when he saw her in the shower but now it was stronger.

He could not even question why she suddenly had something… so big, and juicy. By the looks of it, she could not stop cumming, but didn't want to either. All of that white liquid on her beautiful figure, with that skin of hers… and that big throbbing dick… the tip of it touched the down side of her breasts…

His own cock started to get hard from the sight, and he wanted to give in so badly and just jump in and… but he should not do it. She is his sister after all, isn’t she? But it looks so inviting… Looked so heavenly. His mouth watered more and more.

He needed to leave or give in, and must chose soon.
