My brother came out to me hear me out !!!!!!!!!

So back in 2017 my elder brother(let's call him A) moved to another city to study & while parting ways with his best friend (let's call him S) , my brother's best friend told him "tell your future kids i love you more than your wife ever will" and bolted. My brother told me about it & I never stopped teasing him about it even tho I had the biggest crush on S myself. During lockdown A returned & spent a lot of time with S like the good old days , S continued with his teasing & flirting until A got overwhelmed & started questioning his sexuality. Finally S did a grand proposal (with crackers & shit) to ask A out & A went along with it cus according to him he 'saw the look in S's eyes & just couldn't say no & hoped to catch feelings on the way' . 2 days ago , A finally told the 3 golden words & today he came out to the world saying "Im 'S'sexual " lmao (it was cute tho) and I was like bruh I hate that you get to pound S's ass away I'm jealous~(I'm into pegging) & he was like "I'm the one being held tho??' and I was so shocked cus my brother has toxic masculinity and is 5'11 but super muscular & S is 6'1 but kinda lean ? Anyway they look super cute together. This question is posted here for y'all to comment F as my heart broke just a lil (I had it bad for S , he has the face of an angel)
