I was invited by my senior to attend a party, where I met a suspicious, promiscuous-looking married woman and her husband, along with my senior's couple. As everyone was chatting and getting along, my husband—the youngest man there—was playfully groped by the promiscuous wife. When I tried to intervene, she suddenly lifted her skirt, causing all the other husbands to swarm around me and grope me relentlessly. Among them, my senior's husband took me to the bathroom and asked me to suck his erect cock. At that moment, the promiscuous wife began giving my husband a blowjob right beside me. Fueled by rivalry, jealousy, and arousal, I sucked wildly and intensely. Afterward, I was taken to a room where my senior's husband used various sex toys on me and fucked me so hard and rough that I was driven into a state of complete, overwhelming ecstasy.
