Filled with lust, they both keep going

From Torg Adventure

Jenny grabbed his head with both hands and kissed him again, her tongue darting past his lips to play with his tongue. Jimmy shifted a hand to her ass and gave it a firm squeeze. She began lifting herself up and down rubbing her slit up and down his thick shaft. They both moaned into the others mouth. In time with her bouncing, Jimmy lifted her ass, getting her higher and higher, until her pussy was at his fat cock head. Her hands flew to his cock and directed it at her weeping slit, breaking the kiss.

"Oh, Jimmy! Fill me with this monster!" she shouted as she pushed it inside her. He took his cue and pulled her hips down, and thrust up with his legs, to bury his cock inside her swampy cunt.

"Aaaaaah!" she screamed as she was filled with cock for the first time.

Jimmy felt the tug of his sister's cherry popping and he opened his eyes wide in surprise. "You're a virgin!"

Jenny panted, then said breathlessly, "I was. I didn't want you freaking out about taking my cherry. I'm so glad it was you."
