Neck biting for Cassidy, when it comes to vampirism, is a relatively rare occurrence. He barely ever gets those fangs out, especially not for sex, so he'd hardly put it under the vanilla category himself. But when with a guy like Eccarius, who's bitten fuck knows how many necks as a matter of ~ritual~, he sort of sees the point. Anyone can get their neck bit, things below the belt are far more... intimate. Human lovers kiss, lick and bite all over, maybe vampires just take it the extra step with fangs. Maybe. He's not really well versed on this.

"Point taken, love. Just make sure it all stays attach-hah-ed, ooh, christ."

He arches up into that mouth, even with the scrape of pointed teeth constantly threatening, legs tightening around Eccarius in encouragement. Fuck it, Cass, it's something new, stop thinking so hard on it all and just enjoy the ride.
