Your step-mother, the doctor. The COVID researcher. If she says that she needs your young semen for her antibody research, what step-son do you have to think she'd lie? Even if it does seem like she's really enjoying this...the teasing, the...ass play. And when she breaks out her thick strap on and tells you to get on your stomach, it seems there is no denying she loves fucking her dear boy hard, right in the ass, until he explodes all over the bed. All in the name of science, right?
