Bro, no negatives and only positives indicates he likes how she looks, that's why I brought that up. why can't you comprehend that he may like bigger girls 🤔
You assume much, he's said she's cute and hes attracted to her, and never ONCE said anything negative about her body. Just cause she's not your type doesn't mean she's not his, like I said at the beginning
The extraction itself, yes is like half cheating. Many will excuse, many won't. Putting your mouth on her nips and drinking her breast milk? 100% cheating
