Sinsterhood and a dragon

Later that night, Vampire bat pony and vampire spike move through ponyville s night sky they have their sights set on Rarirys sister sweetiebelle, who now lives in her own house in town, she moved out once she turned 18, and got the money saved up. Unaware of what's happening around town this night, and the danger nearby. She sat on her bed, reading as her window opens. Raritys crimson irises gleaming as she pushes it open. Spike was close by, fangs bared in anticipation of what's to come.

Sweetiebelle looks up

Sweetiebelle- what the

She says as her eyes widen in fear seeing two shadowy figures come in the window. She blinked and they were gone.abd the window was closed.

Sweetiebelle- shirt girl..your imagination is getting to you...must be the lake of sleep the past couple of days due to work.

She says to herself, heart still pounding, but yet she can't shake the feeling of being watched. A few more past and she then sees Rarity beside her suddenly on the bed her eyes gleeming crimsonas her darker mane seems to wave slightly as Rarity'seurs lock onto Sweetiebelle's as spike drops from the ceiling. Sweetiebelle seem to be entranced by her sisters crimson eyes, drawing her in with a otherworldly allure.

Spike- mmm...she's already falling into your power

He husks licking his fangs.

Rarity gives him a look, that tells him not yours, but hers rarity then looks back to her sister, whose eyes are hazed and pink un hue.

Rarity- mmmm...Sweetiebelle might be mine , but after, she's all ours.

Rarity mews licking at her sister's neck erotically as her hoof wraps around Sweetiebelle. She then sinks her fangs gs into Sweetiebelle's furry neck. As raritys fangs sank into her sisters neck. A chilling scream echoed through the room that was quickly muffled by the the darts magic sepping into her body. Spike watched in awe and lust as he watches Ratity start carressing her sistees body as it transforms. Theur sisterly bond just became more sinful.

Sweetiebelkes body convolsed as it became corrupted by the magic and veno in her system. Rarity lays her on the bed and invites spike to join them on the bed. Spike doesn't hesitate. Once again Rarity's horn illuminates purple once more, and her mane extend once more, this time enveloping the whole bed with them on it. This pills them into a rekm of dark pleasure.

Raritys hooves wrap around spike, carressing his form with a unholy graceas they start making out , her touch igniting a fire inside him that melts away yje last of his mortal self. Causing him to stay erect as desired. Sweetiebelle's now crimson eyes open, she has fully been transformed into a batpony, she sits up seeing her sister and Spike making out, she then sees his phallus.

Spike soon feels Sweetiebelle's mouth engulfs his member. His eyes move to see her sucking his penis. Spike continues kissing Raraity as Sweetiebelle continues with his phallus. The 3 vampires now share a new, dark bond with each other. After a couple minutes, spike is taking turns, funcking their pony pussy as Sweetiebelle and Rarity make out. Making sure he cums in both multiple times.
