My husband and I, he wants to have new experiences and I am afraid of losing him

I love being my husband's whore, whatever I ask. I like to have your cock in my mouth and then in my pussy or my ass, and again in my mouth, which gives me all your juices. Since we met, our relationship has been very intense, very sexual pleasure. but the last time my husband wants to discover new things, he offers to invite another woman and has to make me afraid. so I decided to give everything to him and be his submission in everything he asks of me. Sometimes my ass hurts after having sex or using a little big toy, but I say nothing and pretend to feel the pleasure, the pleasure of it.
