Trying to Find a Specific Literotica Story – Husband, Wife, Sex Therapy, Cuckold Themes

Hey all, I’m trying to track down an erotic story I read on Literotica some time ago, and it’s been driving me crazy not being able to find it again. Hoping someone here might recognize it.

The plot centers around a husband and wife who go to a sex therapist to work on their intimacy. As part of the therapy, they’re fitted with arousal-monitoring bands or devices that measure their physical response to different sexual stimuli.

The twist comes when it’s revealed that the husband—who has a small penis—isn’t very aroused during sex with his wife. But when he’s exposed to images or the presence of a large Black cock, his arousal spikes dramatically. The story builds up to a climax (pun intended) where he ultimately gets fucked by a Black man, and this is when his arousal readings hit their peak.

It had strong themes of humiliation, cuckolding, and sexual reprogramming or awakening. If anyone recognizes this or knows a story with similar elements, I’d love to find it again. Title, author, or link—anything helps.

Thanks in advance!
