Theresa, the dark skinned beauty.

You imagine what your white cum will look like on her ebony tits as you stride towards her. She looks up to you, clearly nervous but more than a hint of steel in her eye. You are vaguely aware of Karen and Alex sauntering over to Beth. Up close, you see Theresa is a real beauty, something you had never considered before. She was the newest member of the team and it seemed she took her life seriously in every aspect, including her workout routine.
"Theresa..." You say standing over her menacingly. She seems surprisingly unphased. "Why did you volunteer? A decision which I must congratulate you for, by the way."
She lets out a breath and says; "Well... I am not getting any younger and... I've always been a very practical person. And... Well... Your presentation... Convinced me." Despite the nervous pauses and anxious shuffles, she maintains eye contact, and you realise she is genuine. Theresa truly believes becoming a vampire is the best thing for her, a realisation which is as pleasing as it is arousing to you.
"Well." You say, smiling warmly and broadly. "How very astute of you. Y'know, I think you deserve a little reward for that." You crouch down, and slowly unzip her trousers. She, of course, lets you. You pull them completely off and toss them behind you. Underneath are a skimpy pair of panties. You pull them back slowly, revealing her pussy last. The pink of her inner vulva contrasts beautifully with her dark labia skin. She is completely clean shaven. In fact it seems like the hair follicles have been lazered away leaving her pussy smooth. You look up at her and she half smiles at you. You reach down and kiss her labia once, tenderly. Then you stretch up and meet her lips with yours kissing deeply. She sighs and shuts her eyes, clearly enjoying the kiss. You dexterously unbutton her blouse as your tongues twist and play. You pull back, a string of saliva briefly stringing from your mouth to hers. Truly she wants this. Not a hint of fear, doubt or regret exists in her expression. You fold back her blouse and remove her bra to reveal her dark nipples. Her breasts are large but saggy, and the stretch marks on her stomach prove that child birth has left its mark on her body. Despite this, you smile, for this beautiful woman, one so deserving of the gift she will soon receive, will have her physical imperfections wiped clean and be reborn as a thing of eternal perfection. You kneel slowly, staring into her lusty brown eyes. Your hands move from her breasts down her waist and rest on her toned thighs. Her cunt is now sopping wet. You put one thumb to the top of her slit and separate the folds to reveal her hard clitoris. Then you place the index finger of your other hand onto it and massage gently. Theresa moans softly and her head lolls backwards. You continue to stroke for a moment longer, before reaching into kiss her sex, your lips sucking at it slightly with each touch. You press harder with your lips, adding in your strong tongue. She moans and begins to sway slightly. You push in closer, opening you mouth wider, letting more of your tongue contact her clit, even as its tip slides into her vagina. You press hard, your teeth beginning to graze her clit. You continue to tease, this way, your hands wrapped around the back of her thighs to prevent the writhing woman from moving from your touch. Then, you bite down, sinking your razor sharp fangs into the soft walls of her vulva. She screams in overwhelming ecstasy, grabbing at the back of your head to pull herself further onto your fangs. The blood gushes into your mouth as her multiple orgasms shake her body, each quiver sending yet more blood into your mouth. Finally, she subsides, drained of lust and blood. You pull back and admire your work. Instead of turning pale, a grey sheen passes over her dark skin, spreading from her gaping cunt. Her already impressive muscles tighten, her belly forming beautiful lines as her stretch marks disappear. Her breasts perk up, their nipples losing the slight scaring they once had. The wrinkles that were beginning to show on her face smooth over as her mouth yawns open, revealing her starkly white fangs. She opens her eyes lazily and looks up at you with her glowing crimson iris', a smug smile spreading across her face.
"What a lovely dream..." She mumbles, her eyelids drooping. But then her eyes snap to attention. She reaches down with one hand and parts her vulva lips invitingly. "...But the morning is far more exciting!" You laugh as you take the invitation, shoving your penis deep inside her. You arch over her, hands fondling her voluminous new breasts, lips locked in a heavy embrace. Her nails dig into your back, gripping tighter with each heavy thrust. The chair bucks and slides under the pressure. Your rhythm speeds up, you thrusting and her squeezing her considerably strong vaginal muscles, until you reach climax. You pull out at the last second, and spray a thick load of white cum all over her orgasmic body. The load hits her face, tits and trails onto her navel. Her orgasm complete, and she smiles up at you, one hand massaging the sperm into her tits, while the other brings a dainty finger to her lips to taste your seed. The white against her black skin looks just as good as you imagined. You look around to see what your companions are up to. Clarice is sitting with her back to a wall and has Evelyn's hair in her hands as the goth chick tongues her vulva happily. The girl's butt is thrust into the air, giving you a tantalising view of her clit ring jiggling with each thrust of her tongue. Karen and Alex have Beth sandwiched between them and are taking it in turns to kiss her plump lips. Their bizarre game has the three of them in fits of laughter.
"Mmm simply gorgeous." You hear a familiar voice muse. You turn to see Gwen stand up from her perch, a finger sliding inconspicuously from her fancy lingerie. "You really are a talented bunch. But now we have work to do." The others begin to stand to attention, and Theresa rises and puts your arm around her.
"As you can see we have a little hunt on our hands." She smiles devilishly. "Its time we brought our friends into the fold."
