After my son's father died we became very close and for more than two years I only had sex with my son. When I've met my second husband I've told him that I only wanted a relationship with him if I still could have sex with my son. He agreed and after some time he asked if I was interested on having a threesome with him and my son. That was a dream come true. Since then and every time my son is available I get fucked by the two men I love the most.
