Creating a trend called the spiked drink dare/game.
Girls in a mixed gendered group will take one shot each. One of them will be rendered semi-unconscious, and the men will have their way with her.
Thing is, not all the girls are there to get laid. Some of them joined due to peer pressure and think 1 spiked drink out of like 20 is pretty good odds if it means fitting in. They might even think being drug raped, while repulsive, is cool.
I’d actually like my story’s protagonist to be a feisty, plucky girl who thinks she’s found her clique. She attends her first spiked game and sees the victim being relentlessly pounded, but still doing consensual acts like blowjobs. That victim is celebrated as being badass for enduring the dare. The protagonist has mixed feelings about it.
The second time she goes, for some reason, maybe she just met a guy - she really doesn’t want to get laid this time (wait what if it’s the victim that had a change of heart during the second game. They expected her to be a slut like the first time round yet she’s fighting back.).
Ok, so, she gets the spiked drink and tries to leave but it’s too late. They even whip out handcuffs to restrain her to a bed as punishment for refusing to follow thru with the dare. She’s raped nonstop overnight. They cheered. She doesn’t know exactly how to feel as she just became the most “popular” girl around.
