It’s been a difficult time since that night with Billy. All y/n could think about was the way he treated her and the constant reminder of her two best friends wanting her about him. She should’ve listened, but she didn’t. She didn’t expect the consequences to hit her this hard.
It’s been almost a month, and y/n has been trying her best to dodge Billy as much as she can. She’d avoid parties and decide to drink at home alone or with Steve and Eddie.
No matter how much y/n tried to hide how much life had changed for her since that night, Eddie and Steve have been worried sick for her. They knew something was wrong, they just didn’t know what, and when this vibe change started.
“You sure you don’t want to go to the party tonight? It’s like right down the road,” Steve asked y/n, but y/n shook her head as she stayed bundled up on his coach under one of his thick covers.
“You haven’t been in the mood for parties lately — Are you good?” Eddie asked, not thinking he’d ever ask that in his life. He hated when y/n went out because it was dangerous, especially with everything that had been happening in Hawkins.
“I’m good,” y/n said, halfway falling asleep due to the liquor she had consumed.
Eddie and Steve decided to leave the questioning alone and start cleaning up the living room. Y/n had drunk the most, so for her to be asleep right now wasn’t unexpected.
“Maybe we can talk to her about everything tomorrow. It’s best we ask sooner rather than later. Anything could be wrong, and I don’t want to be too late,” Steve said, which Eddie agreed on.
After carrying y/n upstairs, Steve and Eddie went back downstairs to debrief about what could’ve possibly happened to y/n to make her personality go south. She had never been the type to seem so drained and dry, yet here she is.
As the two best friends were in distress downstairs, Billy was energized, watching y/n from the window as she had a horrible dream. A nightmare she hadn’t been able to shake for weeks.
The smile that grew on Billy’s face was sick. He had always been a sick individual, but ever since that thing got him, he’s been worse. It’s almost like his true self if finally free and comfortable.
“You’re too perfect to leave a scar on, princess, but I really wish I could mark you,” Billy whispered in y/n’s ear, still having his hand grip her hair tight enough for her to stay in place. There was nowhere to go.
“Maybe I should mark you another way, hm? I think that would be the best for the both of us unless you want people knowing exactly who you belong to,”
Y/n’s eyes only teared up more as he watched him pump his cock, smearing the spit he had just spat all over his length.
“C’mon and open up — Let me see that tongue for a good cum shot,”
Y/n’s stomach turned as she continued to wiggle in his grip, still trying to get away. He had already used her, so why did he need to continue this? Why did he have to mark her face? Why did he have to continue this humiliation?
“Whatcha dreamin’ abt, princess?” Billy asked as he finally made it to her bed, hovering over her as her body twitched underneath him. He could tell the dream she was having wasn’t delightful. He just knew he had to be in it.
“Let’s see how long you’ll stay asleep,”
Billy took his time with y/n. Undressing her was something he craved every night. She just looked too good for him not to see her fully naked. She belonged to him, so he deserved every inch of her body.
“You just don’t understand how much I need you. This thing inside of me gave me the push I needed — I’m so thankful,” Billy whispered his last few words as he slowly grinned at her now naked figure.
Billy swore his body would fall apart. It was hard to hold himself back, even though he wanted to go slow. He wanted to take his time with her since the boys were downstairs, too busy talking amongst each other.
Y/n’s body was so damn soft, he just knew once he got inside of her, he’d crumble just like he did last time.
“Fuck, baby,” Billy groaned as he started palming himself. If he didn’t start now, he’d bust too fast. “I swear if you wake up and start makin’ noice, I’ll flip,” Billy said as he came up between her legs, slowly guiding his length towards her entrance.
He didn’t expect her to be dripping. Maybe it was a natural reaction, or maybe she loved being violated like this. Either way, Billy was in luck.
“Tightest fucking cunt I’ve been in, baby,”
Billy pushed through y/n’s slick with so much ease, he could’ve sworn it would never stop.
“Ssh, ssh, don’t start,” Billy whispered as he began snapping his hips, wasting no time to do what he came here to do, even if that meant she’d wake up and start screaming.
“Hmm,” was all Billy heard as y/n started waking up. She didn’t quite know what was going on, so he quickly slapped his hand over her mouth before she could make a noise. That quickly woke her up.
“There you go, baby. Take me in,” Billy groaned as his cock coated with her juice, allowing him to slip into her easier than before.
“Hey- Hey!” Y/n finally understood what was happening. Even though she was still halfway asleep, seeing Billy’s face was never a delight. She hated his existence.
“Nah uh, don’t start all that cryin’, girl. You were just enjoying it,” Billy said as his free hand pushed her waist into her mattress, forcing her to stay in place as much as he could make her. Billy was already strong, but with this new strength, y/n felt like she had absolutely no chance.
“No, help! — Help!” Y/n tried screaming, but couldn’t make Billy think how great his timing was tonight. Steve and Eddie have no clue what’s going on upstairs in their guest room.
“You think they can hear you, princess? I don’t think so. Maybe you should just give up on it, yeah? Enjoy my fucking dick,” Billy spat.
Y/n’s cervix instantly began to hurt. Billy knew he was going to bruise her tonight. He needed to. He needed to mark her every time he was finished with her.
“Think you can take my load?” Billy genuinely asked, thinking y/n would actually answer, but of course, she didn’t. Why would she? He’s violating her from the inside out.
