Molly screamed. She could feel her pussy explode as Tom fucked her. Her mind awash in the pleasure she was receiving. Slowly she became aware of another sensation, Tom was sucking her neck. However, this time was different than others she had experienced. She could feel a slight stinging. Her cloudy mind raced. Was he biting her? Her eyes opened. She could see Ava behind Tom, her naked body pressing against him. She was encouraging him.
"Bite her," Ava hissed. "Feed on her."
Tom was entranced. The euphoria that overtook him as he sucked the blood from Molly's neck was all encompassing. The more he sucked, the more he wanted to keep sucking. He felt an inner hunger he had never before possessed but which had been growing ever since he met Ava a week ago. The fact that, as he sucked on Molly, his cock continued pumping into her only heightened the experience. He groaned as he came in her. He could feel her pussy gripping his cock, milking him of his own precious fluid as he drained her of hers. Ava continued coaching him.
"Suck harder. Enjoy the sensation as you feast upon your first," she groaned into his ear.
As she said this she rubbed her naked body against him. Tom could feel her erect nipples pressed against his back. Her hand that had been gripping his hair and pushing him against Molly was now caressing his shoulders. He could feel his hunger slowly subsiding. Finally he pulled away from Molly's neck. He groaned loudly. Molly was weak, feeling faint. She looked up through heavily lidded eyes at Tom. His lips were red with her blood. She could see his teeth. They were longer and sharper than she recalled. She saw his teeth retract slightly as she passed out.
Tom smiled while looking down at Molly. Blood was slowly oozing from the wound on her neck. He was satisfied, his hunger temporarily sated. Ava slipped off of Tom's back letting him up. She kissed him hard, licking some of Molly's blood from his lips. As they broke their kiss she looked at him with a wicked grin.
"How was it?" she asked.
"It was," Tom paused, thinking of the right word, "invigorating."
Ava laughed and kissed him again. She pushed Tom onto his back beside the unconscious Molly and straddled his waist. She licked and sucked his neck, moving down to his chest, teasing his nipples with her tongue. She kissed and licked lower until she was just above his rapidly growing cock. Ava smiled up at Tom as she took him in her hand and slowly stroked him then lowered her mouth onto his cock. She swallowed him deep. Exhibiting no sign of a gag reflex she sucked Tom's cock fast. On each pass she came up to the tip and then back down to the base, her nose pressing against his abdomen.
Tom threw his head back as his hands moved onto Ava's head, his fingers entwining in her long red hair. Gripping tightly he urged her to suck him faster. Ava growled at his insistence but allowed him to fuck her face faster. She hummed softly as he used her, making him moan loudly. Tom was in heaven, his cock swollen and pulsing, he knew he was on the verge of cumming. Ava sensed this and suddenly pulled her mouth from his cock. Tom looked down at her with a pleading look. She laughed and slowly slithered up along his body.
