Kerr was surprised - no, not surprised, that was too strong a word for something he'd anticipated would happen sooner or later. He was mildly startled by Ben's instruction. Mostly, he was fucking excited. As Cain stood before him, clearly debating how to alleviate his stress, he looked the boy up and down unabashedly.
He was definitely a man now. Broader, stronger, more rugged. Those soft pink lips and huge blue eyes did give him a baby face - and a doll-like beauty that rivalled Ben's, Kerr had always thought - but his square jaw was more prominent and counteracted the prettiness. Partially. Kerr loved his thick neck and muscular arms, he wanted to feel them wrapped around him and squeezing as they kissed. His thighs looked strong and the bulge in his jeans-- was gone before he got a chance to assess fully.
When Cain knelt, Kerr was mildly disappointed so when the mortal paused to look up at him, he took advantage of it and swooped in for a kiss. He grasped his face as he'd been wanting to do since Cain stepped out of the lift, allowing the stubble of his partial beard to graze the skin of his fingers and palms. His hands pushed forward and threaded into his hair, grasping its luxurious length in his fists and using his grip to tilt Cain's head at the perfect angle. They'd never properly kissed before - well, not sober enough to remember it, and not like this. It had all been chemical attraction, lust and heated looks but very little substance until this point. They'd ground against each other, got breathless and insanely horny around each other but never consummated anything. It was definitely time.
Kerr's tongue was welcomed eagerly into Cain's mouth, the muscles sliding together as their lips undulated sweetly. Cain tasted minty. Had he brushed his teeth or popped a mint before arriving? Adorable. Kerr smiled against his mouth, finding him delightful because he was so eager to please. The other times they'd been together he'd been exactly the same, it had always been Kerr putting constraints on them. There was no guilt this time, however, for his and Ben's relationship had evolved again - hopefully to include Cain.
Previously, Kerr's kisses had been directed at Cain's throat, before the bite. He wanted to move this delicious kiss southward as well (getting closer to that lovely pulse and pounding heart energised the beast within him) but the temptation of Cain's mouth was too great. Kerr broke the kiss by degrees, drawn back for a last peck before there was enough distance between them to look into Cain's eyes. "It's so nice to see you again," he sighed, watching as his hands uncurled from Cain's hair, smoothing it back into place quickly before he slouched back on the sofa.
Because he was so large, it often took Kerr a while to get hard but the excitement of being close to Cain again and the heated kiss already had him aching with discomfort. It was a great relief to help Cain get his pants open and set his erection free - he hadn't worn underwear. As he slid his ass closer to give Cain better access, his hand fell sideways, fingers creeping beneath the hem of Ben's shirt so his hand could rub his back while Cain set to work. Kerr hissed in air and arched upward helplessly as the heat of the mortal's mouth engulfed him. So hot. It'd been a while - not since Charlie, he thought... but thinking wasn't something he was particularly focused on just then.
Kerr murmured soft encouragements, telling Cain how good it was, how amazing and beautiful he was, how nice everything felt as his other hand moved to the mortal's head. He ran his fingers through his hair, cupped his face just to feel that stubbled jaw working on his cock, trailed down his throat to caress and squeeze. Cain was extremely skilled at what he did and Kerr was amazed by how rapidly he was building. He'd cum hard in Ben the night before and his body didn't tend to remake semen quickly so there wouldn't be much for Cain to swallow.
He looked at Ben, waves of love, gratitude and desire flowing towards him. "Kiss me?" he requested, knowing it would make him peak quickly if his lover joined in - though it would be okay if he wanted to observe the effect of his order, too. Kerr's hand wound from his back towards Ben's front, wanting to fondle him while they kissed and he was serviced by a truly divine mortal mouth, swept up by the power of the moment and by finally having something concrete with Cain.
