Colin stepped back from the girl that had just brought the guy who was working sister to climax. He took hold of the other girl by her hand and lead her to the nearby patio table. He turned her to face the table, then gave her back a gentle push until she was bent forward. Once he had her in position, his ready cock slipped into her and he started f**** her. "No, I do not believe so. She seemed more interested than anything else."
After having his fill of her sexually he stood her up as he felt her getting close to her climax and sank his fangs into her neck. It was the last climax she would ever have. He drank until he felt her heart stop then let her fall forward onto the table once more. He slipped out of her and dove into the pool to clean off fully sated both sexually and his thirst.
