I think I took some Christmas night flirting a little too far but I want more from him

Gotta use the throwaway for this! (First post so im sorry if this isnt great!)

My brother in laws cousin often joins our family Christmas activities, which is great, the more the merrier and all.

I always have a great conversation with Alex (let's call him Alex) whenever I see him. He is pretty quiet, funny, but definitely not particularly forward. I think he is gorgeous as well, but I have always been in a relationship and I know that he is quite religious, so it's never gone past a cheeky joke etc. Til' last night.

This is my first Christmas single in almost a decade. I'm doing okay but it's hit a little harder over the Holidays. Last night I spent Christmas with my sister, brother in law and both sides of their family. Alex was there, besides the younger kids/teens we are the only single ones. So my sister ensured we were sitting together which was great. We chatted almost the whole day, I don't think until after dessert I noticed a button on my dress had come open (I am pretty well endowed in the chest department) and I noticed Alex had looked down a couple of times. Super quickly but enough to get my mind wandering a little. Feeling his leg pressed against mine at a crowded table and the dress button got me a little worked up.

He turned to me and said "I'm really sorry to hear about you and John, you guys seemed happy together" which wasn't really the case and we got to talking about it, the table was emptying into the living room and the deck so we had a little more privacy. I mentioned wanting to get back out there but not having the confidence to jump in just yet.

I noticed his gaze flicker down to my cleavage again and when he realised I caught him he went bright red "sorry... your uh.. your button"

I like to think I played it off like I didn't know and acted surprised as I popped the button back in, when I looked back up he was still red "I shouldn't have been looking thats on me"

I jokingly said "to be honest its good to know I still have it" and smiled. Still red but he laughed it off. We chatted a little more but he got up to have a chat with the guys and I went to the living room with some of the others.

Later that evening we found ourselves alone in the kitchen...

"Are you checking to see if I have a button open again?" I asked, jokingly

"I'm so sorry, it was just a reflex, I'm normally so good at not gawking"

"You weren't gawking!"

"i looked too many times, I'm normally more of a gentleman than that!"

"It doesn't mean you're not a gentleman, it was just a peek!"

"It was the look you caught, there have been way too many others and I finally got caught out"

"Today"

"Other days too"

I felt a rush, he had never said anything like this before and I have to admit I was almost proud? Like I had accomplished getting the good Catholic boy to look at my tits? I had to press more

"Which other days?"

"I don't know, just other days as well"

"Alex have you been checking me out!?"

He went red but smiled a little as he poured his cup of tea, "well yeah, but you were with John so I didn't exactly stare... not like I did today"

I laughed "should I ask if you liked it? Or will my ego be crushed?"

He looked up, and looked me right in the eye "I liked it... a lot"

I felt a little twinge between my legs... he looked so good and knowing he liked what he saw... I couldn't help myself

i kept the eye contact with him... and unbuttoned the top button of my dress, then the next, which sat mid bra level and opened the material a little so he could see my cleavage and a little of my black bra with lace over it, it's cut low so he got much more than he would have bargained for

"Fuck... what are you doing to me?" He said looking from me to my chest... not knowing wether to hold my stare or take in my tits...

"I don't know but... I want you to look... is that OK?"

He nodded, and licked his lips... im not sure if he realised he had done it or not but I wanted him to touch me so badly but he wasn't moving... just looking across the kitchen counter... so I walked around the counter to him, intentionally breathing a little heavier so he could see my tits rise and fall with eash breath

"Do you want to touch them?" i asked... looking up at him, moving closer in

He looked down and almost groaned "I really want to, but if anyone can walk in"

i stepped back... feeling a little rejected.. but I saw his pants and the bulge inside them... he saw me looking and he said "I really do want to..."

Probably for the best because a few seconds later my cousin walked in. Alex leant over the counter to hide himself and I opened the fridge door to get a drink out, buttoning one of the buttons and leaving the room.

When he left he gave me a hug, the same as everyone else but I ensured that I was pressed into him that extra bit more.

Im seeing him again next week and genuinely don't know if I should take it further or if it was a mistake...
