Mouse Caught in Step-Dad's Trap

I discovered my son and step-daughter engaging in intimate activities in their Halloween costumes. I am not accepting such behavior under my roof. I pivot my lustful step-daughter and proceed to engage in intense sexual intercourse with her.
She appears to enjoy it and even performs oral stimulation, the bold young woman. I conclude this teaching moment by ejaculating inside her vagina for a raunchy internal climax.
