Are you talking about the grope ,squeeze scenes with Martha, Vera and Lucille ? Vera is in the library in the evening, Lucille in the kitchen after dinner and Martha is abit trickier as you have to take a bath in the morning (or afternoon though i think morning) you'll get an option between masturbating or just bathe. If you masturbate Vera will come in and give you a handjob if you pick just bathe she'll just kick you out. After that Martha will pop up in storage next to the kitchen. You can interact with them at these times and places. First you'll be able to grope their breasts then once you've upped your MC's stat and the girls stats you'll be able to do more. Squeeze breasts , grope ass, squeeze ass.
