I have had multiple 3 somes, always with couples so i was a second cock. Three different couples, always had diffetent rules. First one was superb, we meet and had a meal, the lady was flashing me and feeling me through my trousers, one of the rules, trousers not jeans so she got me more aroused and it was very visible. Then headed to my room where she stripped me naked whilst hubby took pictures. She then lay me down on the floor and played with my cock with her high heels on and slowly striped for me. Perfect view up her pussy....my cock was hard. We moved forward from there.
Second couple, i arrived at their hotel, rang the guy who said they had started without me and had left the door open. I was to be quiet, strip off as soon as i walked in. So i did, then saw him licking her out whilst she was blind folded on the bed, he indicated i should move towards the top of the bed, he then took my hand and her hand, my hand was placed on her boobs and her hand waz placed on my cock. He then told her to give it a good tug. Not sure if she knew it was a second cock at that time. After a few seconds he headed back to licking her pussy, she now knew for sure she was wanking a new cock that she hadden felt or seen before. Moved into the next part of the action
