Guys gf either wants to split up or open the relationship during college. They’ve known each other their whole lives I think?? They’re both 18. Guy is pissed and breaks up with her on the spot in his car I believe. Long story short, the guy ends up with the ex girlfriend’s mom. There’s a lot of ex gf mom stories but this one was actually pretty well written and the sex scenes weren’t over the top with the mom screaming at the top of her lungs and shit.
