The release

Rick's large hands landed on Kate's soft pale skin. His hands were extremely masculine and slightly rough to the touch. It sent sparks of electricity up Kate's body and she wanted to give herself over to him. As his hands ran across her back he finally found her hips and gripped them tightly. Without pausing to remove his blindfold or gag he sent shockwaves up Kate's body as he impaled her inflamed cunt from behind. Rick spread his legs outside of hers, raised his shoulders and fucked her as hard as he could.

Kate could feel his hanging scrotum swinging and slapping against her clit with each plunge into her slit. Her climax was growing to new levels she had never felt before. She finally opened her mouth and released the wad of bedsheets she had been chewing on in restraint and let out an audible sound of "Oh my God! Oh my God!"

Jan stopped in shock, worried that Rick would recognize Kate's voice, but she was careful not to intercede. She stood there motionless with her fingers deep inside her own pussy, half standing and half sitting on the edge of the bed.

Rick picked up his pace even more at the moans as if he was unable to recognize the difference in Kate's voice.

"Fuck me! Fuck me, you fucking MONSTER!" Kate let out in a voice that was getting uncomfortably too loud.

Rick leaned forward, wrapped his large arms around her and firmly grabbed her hanging tits sending her into an explosion of an orgasm. His naked body pressing up against her back and his member pushed deep inside her as she convulsed in the greatest climax she'd ever felt. With another pump of his hips he then shot his hot load, filling her pussy as they collapsed onto the bed beside each other.

Kate opened her eyes as she started to come down from her climax and she could see Jan sitting half on the bed with her legs spread wide open and her two fingers rubbing furiously at her own clit. Jan was getting a rush from watching Rick fuck Kate to an orgasm, but Jan hadn't got there herself just yet.

Jan made a nod to Kate towards the doorway once she caught Kate's attention. In a sudden realization that Rick was unbound now and could at any moment remove his blindfold to catch their forbidden affair, she rolled off the bed. Kate grabbed her pajamas from the floor as she made her way out the door and mouthed, "Thank you!" to her sister.

Jan watched as Kate left the room and noticed Rick's warm cum dripping down from between Kate's legs. She grinned with a feeling of success and was glad that she had convinced him to get that vasectomy two years ago. She then turned to Rick who was still laying motionless on the bed in a post-nut trance.

Kate scurried to her room completely naked with her pajamas in her arms. As she headed down the hall she could hear Jan's voice saying, "I'm not done with you yet fuckboy!" Kate smiled as she headed back into her own room and closed the door behind her.
