wait. I have a twin?

Angels first shower.

#warning: MENTIONS OF SMUT AND MATURE CONTENT.# 

After Kayla let go of her brothers embrace, she grinned at both of them "Alright. I'm gonna take a shower. Don't wait up" Kayla said as she pointed backwards with her thumbs  before smacked her lips and clicked her tongue before she was about to disperse. Hearing this absentmindedly Cas asked "want me to join?" after realising what he said, his eyes widened as his cheeks turned into crimson rose of a colour as he looked down to the ground. 

Kayla's eyes widened before turning back to face and see an equally horror looked face on her brothers face as though they're saying "is he seriously asking her to bang her in front of us?" It was awkward before Kayla nervously chuckled and walked up to Castiel and held his hands with both of hers "honey...um...that is not a question to ask in front of your girlfriends brothers but" she gave more emphasising on the but making Dean and Sam's eye widen even more "if you want... I would love for you to join" Kayla smirked before she gave him one peck of a kiss on the side of his mouth to keep him on his toes. 

"I'm outta here!!" "Right behind you!!!" Dean and Sam practically scurried out of there feeling awkward as possible while doing it before leaving and running to Baby and driving to get a drink and not think about what just happened. 

Cas was now alone in the living room thinking whether he could just disappear or join Kayla. His face was filled up with heat as he was thinking on how it's suppose to go. He was nervous, he knew he shouldn't have asked that but he did... He feels his heart beat rising and becoming more faster than it already was. 

"guardian angel?... the offer is still open if you want it" Kayla asked from the bathroom upstairs with a hint of a blush as she bit her lip cutely. Cas cleared his throat before he deliberately pushed himself off the couch and went up to her to say that he made a mistake but he saw her in this silky Pearlie white robe making her look like an Angel. He couldn't stop staring at her as he laid his eyes on  her and moving up to her as though he was in a trance. Kayla softly smirked before Cas was full in the bathroom and closed the door behind him and locking up. 

Kayla went up to him and wrapped her arms around his neck looking up to him and smiling before saying "I never thought that I would have shower sex with an angel before." 

#ladies and gentleman! I advice you to skip this part until you see an "All clear sign" because the smut and mature content is now commencing. Good day/afternoon/evening. Enjoy the rest of the book#

"well..I thought I would never have intercourse with anyone in my life let alone human" Cas said with a soft smile. "well..let's change all these" Kayla softly purred before she started kissing him and untying his tie and dropping it to the floor before Cas shook off his trench coat while Kayla unbuttoned his shirt and slipping it off of him, when all of that was done, they started working on his pants and unzipped it before removing the one button of its place before he skimmed it down from his legs and was helped her also to remove his boxers still never stopping their kissing all this way.. She caught a glance at his member and her heat started to rise up as she seen it.Her mouth was wide opened as so were her eyes "wow..God knew what he was doing" She muttered before kissing him again. 

Cas smirked before removing he robe off of her and gazing at her whole body "looks like my dad knew what he was doing with you" he said before he started to slowly push her in the shower and started to kiss her nape down to her chest and on to the other side. Kayla let out one breathy moan before turning on the water to heated warmth as she let him do what he knows for now. "Kayla?..Am I doing this right?" he asked still going on 

"oh you don't know how much" Kayla replied in hushed pleasure before he decided to go down on his knees and face her private area. He gulped as he hadn't no Idea what to do before Kayla looked down on him and smiled before she said "question?" she asked with a soft cute giggle.
