Connor was well aware of the...innuendo that the cuffs brought, but the Devil's trap would prevent the demon from escaping. He did sallow, his face reddening as she leaned into him, and he chuckled, throaty and huskily, "Yes, cuffs" He said softly.Connor did not have an iron will, and he couldn't help himself. 

He leaned in and kissed her, every inch of passion, of heat, of lust projected into it, and he pulled away, slightly out breath, and he tucked the Latin Book under his arm, taking one of her cuffed hands in his, starting towards the doors, looking about to making sure that there was no one watching them, and no other supernatural entities around, looking back to the church, a sense of calm flowing over him as he did so. 

Curches were holy grounds, for which Connor was grateful.
