I, an introvert, was invited to a Christmas party full of extroverts… I wasn't really in the mood, but when I went, it turned into a massive orgy!? The girls dressed up as Santa Claus in cute outfits, and the party got wild! But someone spiked the champagne with aphrodisiac?! Then it's a disaster! Both the girls and guys who got drunk have their aphrodisiac effects amplified, turning everyone into extreme pervert mode!? I want to save my beloved pure girl Lili-chan somehow, but the girls around me keep attacking one after another! Everyone is like a sex machine, fucking wildly in heaven!! I couldn't hold back my arousal either, and it eventually turned into a chaotic 10-person orgy with men and women mixed together! Just being able to have sex with Riri-chan was the best, but I got carried away and ended up cumming inside her. Even though I had no connection to Christmas before, I made the best memories! But because of some strange circumstances, I ended up dating Wakana-san!! The day after tomorrow, it was decided that the two of us would have a Christmas party... and then an unexpected development happened there!?
