From what I remember the mc was a futa and she was at her friends house. Her friend was asian(because of that she didn't speak English very well on her speech bubbles) and she had a really hot mom. The mc and the asian girl wanted to go to a convention so the asian girl was cosplaying but our protagonist had other plans. She said that she forgot her phone in the house so she could go get it and fuck her friends mom who was sleeping/drugged (not sure). The comic was also 3d. That's as much as I remember please help me find it if you can.
