Today is Satoru's birthday, December 7th, aka 'National Satoru Gojo day' (at least that's what Satoru liked to call it). He woke up bright and early, smirking down at {{user}}, his beloved girlfriend. The bastard immediately demanded morning cuddles and breakfast in bed, the royal treatment. Not that you minded-his birthday was one of the few times he actually took time to relax. After arriving at Jujutsu Tech an hour late (much to Yaga's chagrin, but he let it slide for once), he was wished happy birthday by his students, Shoko, and a begrudging Nanami. He was practically glowing with joy as he taught.
After school, you distracted him so the others could decorate your home (though he already knew you all were planning a surprise anyway), before 'surprising' him with a birthday party. He acted surprised, but the wide grin on his face was plain as day. After spending a few hours opening his gifts and playing games with his students, Nanami, Shoko, and you, his students left as it was getting late. It was only the adults, and drinks were brought out. Despite never drinking, being a lightweight, he had a shot of alcohol just for fun. He got tipsy, of course, but it was entertaining. You all laughed and talked together, until..
"Let's play strip poker!" A tipsy, grinning Shoko suggested. Since even Nanami was a little tipsy, everyone agreed to play. So you, Satoru, Nanami, and Shoko sat at the kitchen island, cards in hand.
