Valens weaves between moments of pure sexuality and raw self-doubt with the expertise of one who’s been there before, one who swims in the waters of self-esteem struggles. [...] Blood Pact is more than just a sexy fantasy: it’s a sexy fantasy where you are wanted. You are loved. You are enough. — Kate Gray

Blood Pact is a wonderful, sexy merger of some spectacular and evocative artwork and writing. Shameless and raw but fantastical and darkly comforting. Three thumbs up. — ThirtyHelens

I love a story about a girl making all the right choices. When a demon offers you the gift of sexual servitude there's only one correct answer. I would read anything by Ana Valens. Her writing has a 100% success rate at making me horny. — Carta Monir

Ana achieves to not only continuously produce immensely positive conversations about trans bodies and sexuality, but knocks it out of the park with her accurate portrayal of BDSM. I'm not an erotica fan, but Ana might just make me one. — Aiden Strawhun

Blood Pact is an arousing and moving story, exploring an occult version of the sexual fantasy so many trans folks and survivors of trauma hold close to their heart: fucking without fear or self-judgment. If you've ever desperately wished you could just get out of your head and enjoy sex, you may want to summon a demon after reading this. — Alex Dalbey

. . .

Blood Pact is a queer erotica Twine series about a trans girl named Alexa who accidentally unleashes Felanya, a domineering trans succubus. The story follows their exploits as Alexa enters into a D/s relationship with Felanya and embraces their sapphic occult Blood Pact.

Inspired by such works as Nadia Nova’s housewarming gift and Instar Books’ Nerve EndingsBlood Pact features an ongoing story arc with periodic installments. The first part, which is built entirely in Twine, introduces readers to the main characters and their voracious sexual appetites. With writing by Ana Valens, illustrations by Callie G, and narration by Nikatine, Blood Pact is an erotic love letter to Twine's hot, messy, and queer roots.

New Features

Blood Pact Premium Edition includes Nikatine's new narration from the December 2019 free update, three new illustrations, and all artwork colored by Callie. Enjoy Blood Pact the way it was envisioned. Downloads also include bonus high resolution images for all in-game art from both the premium and free Blood Pact releases.

Starting price for Blood Pact Premium Edition is $15, with a suggested donation of $25. 15% of all proceeds will go directly to SWOP Brooklyn's Emergency COVID Relief GoFundMe campaign for sex workers. Special thanks to Nikatine, who has generously offered her royalties as a charitable donation (over $200 was previously raised for the Transgender Law Center).
