I can say I was the wildest at the party. I thought I would be more controlled because it was the first time that my brother, his wife and my sister and her husband would let me join their swing parties but it was easy. I was completely satisfied, I fucked all the cocks available there including my brother's and my brother-in-law's. My sister was a bit jealous, I guess it was because I was moaning very laud when her husband was doing me from behind, but at end she already forgot it.
