It is normal to be scared of change. Show him the beauty of vampirisim.

You separate from Karen and drift over to your lover serenely. Around you your fellow vampires begin to select new targets, and the moans, screams and shouts begin anew. You have eyes only for Linus. You smile down at him as you carefully lift his chin, slowly lifting his eyes up in such a way that he gets a good view of your perfect, naked body. You see the tears in his eyes and his arms drooped in defeat. You will him to submission as you lean in close and kiss him, his warm lips burning against your ice cold ones. You sigh as you rest in his lap, gently grinding your hard clit against his bulge. When you look again, his eyes are filled with only desire and lust. You pull his shirt free, which he lets you do willingly, then you breathe in deeply, pulling the scent of his flesh and blood from his throbbing neck. With one swift, violent movement, you strip his remaining clothing and sit on his cock. It is warm and you grip it tightly with your icy vagina. He shudders, his fingers gripping the chair below him, but you simply stare down at his pulsating jugular. You lean in, caressing his goose-bumped skin with your long, agile tongue.
"Mmm you taste so good..." You purr, then slowly sink your fangs into his neck. The blood floods your mouth and the moment it hits your tongue you instantly feel a wave of intense pleasure. Your muscles contract and tighten over his hard penis and without any other movement you bring yourself and Linus to climax. His seed is hot inside you, but you barely notice as you writhe hungrily around his neck, taking in as much blood as possible. Finally you pull back, and admire your handiwork. His muscles grow and strengthen, you see the lines on his face disappear. His penis grows inside of you, brushing deeper within your vagina. His fangs grow out and he looks up at you with glowing crimson eyes. You smile and climb off him, the cum running down your pale leg. He takes your hand and stands, looming slightly over you. You kiss deeply and observe the room together, hands wrapped around one anothers bodies. The meeting room has become a mass of writhing flesh and blood. The few remaining humans are in the stages of transformation, while those who are already vampires are enjoying one another in a chaotic orgy. The groaning and squirming of so many bodies in ecstasy immediately arouses you and, Linus in hand, you enter the fray together.
