Being Shared By My Lover

A while ago I met a woman at work and we became friends. At her house one afternoon she asked me if I wanted to get in the jacuzzi with her. I thought hot tub, but she was talking about the jacuzzi in her bathroom. Naked. She admired me from head to toe, and touched everything, from my nipples to my clit. She wanted to kiss but I held her off.

A few weeks later she invites me again to her house to jacuzzi with her. This time she has some wine and cheese in the bathroom, this time she sits down first and when I get in she holds me by the hips and nibbles at my pussy before letting me sit down. This time we do kiss. After the jacuzzi we get out and dry off and she lays a large towel on the bed for me to lay down on. She stands over me staring into my eyes, and then she shifts her eyes to my breasts and my pussy. She asks me to open my legs and she goes down on me.

The third time, after we have pretty hot sex after our jacuzzi session, she asks if I mind if her husband joins us. I tell her I am not a switch hitter, I am not into guys. She leaves me on the bed, and brings her husband in and asks if he likes me. He puts his hands on me, leans down and sucks my tit. His hand goes between my legs and she takes my feet to open my legs. He gets on and goodbye virginity. He completes himself and gets off and she invites me to take a shower. In the shower I tell her that I understand that she goes both ways, but I don't and it was unnerving to have him fuck me.

This relationship is the longest relationship I've been in, going on four years. She wants to share with her husband and I grin and bear it. I am definitely not bi, she is but I am not. I do it because she wants me to. But in all honesty if I never saw a dick again I would be fine with that.

Didn't mean to ramble, but how to you come out and talk about this. When he stands over me I feel like I'm his prey and I submit to whatever is on his mind that day.
