When sleeping with an older woman you vomit on her chest then slap her in the stomach and when the vomit splashes everywhere you take your hands and rub them through her hair. After doing so proceed to crouch over her face and take a messy shit all over her mouth and rub the fecal matter in every open orifice possible, including ear canals.
