I Have Not Desire To Surrender To Her

Please don't repeat this. I am currently living with a divorced lesbian woman, I rent a room in her house. Her exhusband has residual rights to her and she gives him sex. He has taken to giving me sex too. I started getting head from her after he started having sex with me, basically she wanted to lick out his cum from me. It's pretty disgusting but it has happened more than once.

I am straight woman, sex with him is better than no sex at all. He knows his way around and he can keep it up long enough to get an orgasm out of me. I won't eat her, I just won't. She has sat on my face after he gets off of me to force her nasty pussy in my face and she locks me down putting her whole weight on my face.

I got spanked twice by her for not 'obeying', both times with a wooden spoon. She jumps on me when I am not expecting it and demands that I surrender once and for all. He won't do anything about it and won't make her stop getting on me. I lock the door to my room, but I have to go out to use the bathroom and to eat and stuff and she is waiting. I try to keep the table between us but she is faster than me and she is very strong.

I don't want to move, I don't want to stop having sex with him, he does it for me. I can even take her obsession with licking his sperm out of me, basically because I don't deserve it. It's her riding my face that disgusts me. I don't see how anyone can go down on a woman, I just don't.
