VENX-083 - Father is away on a company trip, leaving me alone with my stepmom

The way he approached his stepmother after his father left for a business trip, her reaction, and even the moaning felt hesitant and half-hearted. The constant creampie lifestyle in the middle didn't really get me excited either. And the ending, where the father comes home and fails to find the two hiding in the bedroom, only for them to kiss in relief—it just left me feeling like the whole thing was half-baked.
