@ivan second one in a row by the same guy, so it's clear it's not going to change. "I could've refused" when he didn't consent at the start. Getting a boner isn't the same as consenting, when consent can only be done by sober, adult people, and a boner doesn't care if you're underage or drunk. "Are you gonna stop if I say no?" Can be interpreted as MC wondering if he even had the right to consent or refuse, which with the response he got, we can assume he wouldn't have.
