Stepmother's unenthusiastic sex leaves me unsatisfied while stepfather is hospitalized

My well-endowed stepdad's hospital stay left me in a rut. I craved his attention, and turned to my voluptuous stepmom. Our lackluster romp left me yearning for my absent stepdad.

I've been in a tricky situation, my stepdad got hospitalized and my stepmom's been acting weird. She's been giving me the cold shoulder and not the way I like it. I know she's been fucking other guys while my stepdad's away. I caught her on her knees with another dude and she was getting fucked like a slut. I was pissed, but also turned on. Later that night, she came to my room and we started talking about sex and stuff. She said she wanted to make up for her mistake and we ended up fucking. But damn, she was not enthusiastic at all. She was just lying there like a dead body. I tried my best, but I couldn't get off. I guess my stepdad's not the only one who's been missing out on good sex in this family.
