8 XXX : Cuckold

I posted "sharing my 19 year old GF with my best friend", and there were pic requests, so here's the 1 other photo. I wanted to add some background info: This was her first time being shared with another guy. We recently started discussing a cuckold situation, but didn't know who to do it with. My friend and I have been really close since middle school, so we figured he was a good choice, so we decided to do it on his birthday. This was a first for everyone involved. We were really surprised to see how huge his cock was!
Enjoy homie. :) Our first experience was in a swingers club when we were 19m/18f. It was crazy. She won a nude dancing contest (easy, since she was the only chick under 30 in the whole place), and later I got to watch a woman and her husband eat her pussy before I fucked the hell out of her. It was great fun between the "young toys" for the evening.
Sweet christ that is an epic cock to start off with.
Does she prefer his cock than urs?
