Boundaries?

I went to a swinger club with my lover. We mingled, and decided to wander into the back play areas. We watched in several rooms where there were threesomes and couple swaps going on. We wandered further and found a group play area. We entered and watched for a bit. As we became more aroused we were touching each other and getting more excited. We were invited onto a large bed with several couples. There were beds all around and quite a lot of combinations of sexual activity. We began playing with the couple. We swapped partners side by side. I’m a bed next to us, we saw girl on girl and guy on guy, and we began to watch while continuing to lightly play with the couple we were with. The couple asked if we were enjoying watching the bi activity. We looked at each other and then at them a bit surprised. They said they were bi, and would enjoy exploring with us. The lady kissed my lover and they began groping each other. She said to my lover, that’s she’s very turned on watching two men and would like to watch me and her man. Again we were surprised and my lover looked at me not knowing how she felt of I felt. To my surprise her man reached for my cock and began stroking. She looked at me and mouthed oh my god. I was frozen and didn’t stop him. He then moved lower and I knew what was coming as he took me in his mouth. My lady attacked me kissing me and whispering it was the sexiest thing she ever saw. Surprisingly it felt amazing. We ended up in a pile of 4 and I sampled giving him a blow job as well. We were surprised and even more surprised how exciting it was. Firsts are amazing, but it wasn’t the last
