Sheila moaned in pleasure as his finger entered her and very soon, he became comfortable, not even waiting for her to put it in again. He turned his finger in her and watched as she bent her head backwards in pleasure and bit her lips.
"Put it in my mouth," she moaned. "I want to taste it."
He happily put his finger in her mouth oblivious of her plans and before he could make a move, Sheila brought her jaw down with all the energy she could muster. Her teeth dug into his finger threatening to tear it in two and he screamed in pain, a loud shrill sound. Sheila recognized the voice immediately.
"So it's you.."
He stabbed at her throat with the pen knife slicing through her vocal chords and she coughed, choking on her own blood.
