I sucked my friends boyfriends cock and not sure what to do

After a night out with my friends we were all pretty drunk. The girls went to bed and a few of us stayed up drinking still. When all the guys went to bed apart from my friends boyfriend it just got a little weird and horny. He said he was annoyed that his girl had gone to bed as he really wanted to cum and I said me too. He just got his cock out and started stroking himself. I dont know what came over me but I just walked over to him and sucked it. I love sucking cock and havent for so long and the fact he unloaded in my mouth after about 30 seconds was incredible. Its now a bit awkward though
