My husband and i, he wants to have new experiences and i'm afraid of losing him

I love to be my hubby's whore, whatever i ask for. i like having his cock in my mouth and then in my pussy or in my ass, and again in my mouth, which gives me all his juices. since we met our relationship has been very intense, a lot of sexual pleasure. but the last time my husband wants to discover new things, he offers to invite another woman, and he has to leave me scared. so i decided to give everything to him and be his submission in whatever he asks of me. sometimes my ass is sore after having sex or when using a slightly large toy, but i say nothing and pretend to feel pleasure, pleasure him.
