First mfm with gf and bbc bull

I’ve been into swinging and Dom/sub play for over 10 years but before that my first real experience sharing my girlfriend with another guy was back in 2007 when I was 28 and had a gorgeous young girlfriend who was 19. Amy was a tall sexy brunette who was wild in the bedroom and into everything kinky, she was interested in meeting another couple and we met a married couple in Brisbane who were experienced and older which we both liked. Neither of us could host so they suggested a friend they knew who offered his apartment for getting to join. He was a 36 year old bbc and was very excited to host a couple with a 19 year old brunette. We were happy with that and on the night the couple backed out and since we were looking forward to such a wild time we decided we would go away. We had a few drinks on balcony in middle of the city and didn’t take long until Amy was stripping naked and then he sat her down and knelt between her legs and ate her out in the open for 20-30 minutes. She looked at me smiling and moaning with her legs wide open then he walked her in to the bed keeping blinds open and she got on all fours with my cock in her mouth as he got behind her spread her ass open and slid in and then began pumping deep as she cried out loud for half city to hear. Then she sat on my cock while he stood over to feed his cock to her until I couldn’t hold it and filled my girlfriend with my load. She quickly laid down and he held her legs up high and wide sliding back inside her then pounded her hard until shooting his load on her belly. We laid there talking for 10 minutes before he started again and he rammed his fingers in while she was sucking him hard and then I watched him give my young girlfriend the pounding of her life for 45 minutes and sent her home with me dripping with cum and smiling from ear to ear. It was that night when I realised that seeing another man enjoying my girl was the biggest turn on I ever experienced and was the beginning of a amazing life that I am only half way through x
