I can kind of relate to your situation. I have 2 stepdau"s . I find that wearing thin material shorts or boxer/briefs , light colors that make my bulge a lil more noticeable and easier to feel when accidentaly brushed against. By me NOT being the aggressor it makes it more comfortable for them to be around. I like to think its like planting a seed to grow in their minds "if" that's what she chooses to think about.
