Maybe Steve is only doing this because he thinks I'm asleep, she thought. If I let on that I'm awake, it might scare him off. Her hips bucked uncontrollably as she came, but she tried to appear as unconscious as possible. She kept her teeth gritted and her lips sealed, thinking that would keep her quiet, but some deep moans just came right out through her throat. Her rippling pussy gripped his big fingers over and over, and she fought to keep her hands from grabbing his and humping furiously. The plodding of her heart beat pounded in her ears while she peaked and then calmed.
"There you go, babe," Steve's deep, slurred voice came from somewhere in the immediate darkness. After a moment of silence, he chuckled. "I know you're not asleep hon, I know you too well. I know you.... and I know you always want more, don't you..."
Ohh! He thinks I'm Jill, Kris thought to herself. I should speak up, he could be really mad in the morning if I let him keep going. I bet he's a really good fuck, though... but I have to say something.
"Ste-" Kris was cut off by his big palm covering her mouth.
"I know, I didn't forget what you like."
What? As she tried to figure that out, his hand left her lips and it was replaced by something fuzzy. The pressure increased and it went into her mouth where she could feel that it was cloth. He had gotten a piece of cloth and was tying a gag around the back of her head.
"Steve?" She tried to say, but it came out "Huvh?"
"Shhh," he said, finding her left and then right wrists. He easily held both of her small wrists in one strong hand. Above her head she felt them encircled by more cloth. When she tried to move them, she realized her hands were tied to the headboard. So Jill was into this sort of stuff?
Her ears perked up as she heard a zipper, and then felt her nightgown being pushed up around her waist. A warm, round cockhead pushed against her pussy lips. A bolt of electricity ran from her clit, up to her brain, then divided to both nipples, hardening them in an instant. Kris felt the weight on the bed shift as he leaned over her. With one hand he guided his cock, trying to find her vaginal opening. She waited with baited breath. After a moment it sank between her hot, slippery pussy lips, stretching them wider and wider until and the head penetrated her, allowing him to go hands-free. He groaned as he pushed his hips forward, slowly burying inch after inch of his rigid cock inside her. Kris's eyes widened as she grew fuller and fuller, wondering how big he was. Maybe the alcohol was making her judge poorly, maybe he was penetrating her really slowly, but she could swear that his cock just kept going and going. She was thankful that she'd been wet first! Kris was aware that she didn't have very much of a choice, and it turned her on a little more. He was almost raping her...he was shoving his whole cock inside her whether she liked it or not. But she did like it. Finally, she felt his pubic bone pressing against her, and he was all the way inside. He throbbed inside her for a moment.
Then her whole body tingled as he began to pump her. Kris lay there and let him have his way with her, enjoying every second. She knew she shouldn't be doing this. Jill was very open, but she might still be a little upset, because she didn't want Steve to fuck other women. Steve would definitely be upset. But she had an excuse now -- she'd tried to protest, but he'd tied her up and gagged her. There was nothing she could do to stop him. It was wrong, but he was soo big, and it felt soo good, and her pussy juiced at the thought of Steve being forbidden fruit. She wished instead of cloth, she was gagged with his stiff cock...
He was drilling her harder now, and she could feel every contour of his long, rock-hard shaft moving inside her. The almost imperceptible noises of sex pounded in their ears; the mattress squeaking, the quiet slurping noises of their slick genitals, his little unintentional grunts, her muffled gasps and moans.
Steve was a little unsteady, but still a great fuck. If this is how well he fucks when he's nearly fall-down-drunk, Kris thought, I'd like to see how he handles when he's sober! She felt some liquid trickle down from her pussy and soak into the sheets. It felt like she was being jammed full of a red-hot steel piston, his cock penetrated deeper into her cunt than she could ever remember feeling. It pounded her dripping juices into a warm froth. She cried out through the gag as she orgasmed again, her cunt gripping and squeezing his meat. Her legs had wrapped around him at some point, and she tightened them, trying to pull him even deeper inside her. She wished her hands were free so she could squeeze her nipples while she came.
"Mmm, Yeah, yeah," Steve started to whisper, feeling her muscles ripple around his cock. He gripped her waist and fucked her harder. "Mmm Jill...fuck...yeah...yeah..." The headboard was now knocking against the wall with each thrust. In the back of her mind, Kris wondered if Jill would hear it and come down the hall. But she was too buzzed and horny to care anymore. She hoped that maybe her sister was listening to them fuck. After all the times she'd watched and listened to Jill getting nailed, it would be a nice change of pace. "Oh...fuck ...oh yeah...mmm" he grunted each time he sank inside her molten hot cunt. His thrusting was different now, she could feel it. With a loud groan, he buried his throbbing cock into her, pressing hard as if he thought he could force his balls in too. Each exhale became a loud sigh as his hips started to tremble. His cock exploded deep inside her, injecting her with his seed. Torrents of hot sperm sprayed her womb, coating her inner walls and dripping out down her crotch. He remained embedded inside her until his balls were completely drained.
Steve collapsed almost on top of her, still breathing hard. Kris had been almost ready to climax again. The ride had been great, but way too short. He could only have lasted 2 or 3 minutes. Now he was spent, and she was fucked figuratively instead of literally. She rolled her hips, trying to hump his cock, but trapped underneath his weight, she couldn't move much. He soon softened anyway, eventually shrinking and slipping out of her body. She was entirely too aware of the warm semen oozing out of her pussy, dripping down past her asshole, cooling, and soaking into the sheets. It drove her crazy and there wasn't anything she could do about it. She couldn't speak, she couldn't get Steve off of her, she couldn't untie herself, she couldn't even see the clock on her nightstand. One thing she could do was cry in frustration.
"What the hell!" Kris opened her eyes in a blurry fog, hearing her sister's voice. She was immediately disgusted by the taste in her mouth, realizing the gag was still in place and was soaking in her spit all night. There was still a heavy weight on her right side, and after a few seconds she remembered why.
Steve lifted his head groggily, hearing his name shouted the second or third time. Jill was standing over him. But he also had his arm around her sleeping form in the covers... didn't he? He looked down to see Kris beneath him, her eyes looking right back into his. As the thought dawned on him, he felt a rushing in his ears and his already pounding headache grew sharper. He pushed himself off of her, slumping on the other side of the bed. He saw that his soft penis was hanging out of his pants, and he put it back in.
Jill untied her sister's hands and pulled off her gag. Kris lowered her sore arms, rubbing her wrists where the tight cloth had chafed them.
"Are you alright?" Jill put an arm around her. "What the hell, Steve, did you rape my sister?"
"Fuck.... Kris, I'm so sorry," he groaned, horrified. "I didn't mean to..."
"What do you mean, you didn't mean to?" Jill demanded.
"It's ok," Kris interrupted. "I'm not hurt or anything."
"No, it's not ok," Jill came back. She narrowed her eyes at Steve. "Get out."
"What?"
"I said get out of this house."
"Jill, will you let me explain? I thought-" he begged. He looked like he was almost in tears.
"No, you get the hell out! Right now!" She ushered him out of the room and Kris was left alone for a minute.
Jill came back and sat down next to her. Kris hadn't moved yet, and didn't realize her nightgown was still pulled up around her waist. Jill could see the dried streaks of cum around her pussy, and the big stain on the sheet.
"Kris, I'm so sorry honey," she breathed, hugging her tightly. "If he hurt you, I'm gonna fucking-"
"No, no, Jill. You've got the wrong idea."
"What do you mean?"
"He was telling you the truth, he really didn't mean to do this. He thought I was you."
"He thought you were me?" Jill frowned.
"Yeah, he just came in my room by mistake, I guess. You saw how drunk he was. He was saying your name and everything. I tried to tell him, but he got the gag on me before I could say anything. "
"Oh... well, that explains a lot, but it doesn't change the fact that he more or less raped you."
"No, it really wasn't like that. I didn't try too hard to stop him. If that was rape, then you've raped me fifty times."
"Wh- you mean you liked it?"
"I loved it," Kris raised her eyebrows. "I won't lie, I'm not really into playing tie-up, but it was fantastic. Jill, you have to let Steve back in. I know he feels awful. It was all a mistake."
"Oh..."
"Jill, are you mad at me?"
