Won't the commander of the tank become upset at us?"I sighed but explained, "Hell yes! That's exactly what it's supposed to do. The fuckers are firing... at Jack and we need to get their attention so they quit shooting at Jack."She eased me into a chair, brought me the stick, and once again questioned, "Are you sure about this?"I yelled, "I'm sure as a fucking heart attack! Now do what the fuck I told you to do before I take this stick to your ass and give you a fucking spanking you will never. She looks up at me with wide, inviting eyes, begging me to cum. And it takes everything in me to grab my dick and pull out of her mouth."Stop, fuck, please." I step back, and she watches me with a pouty stare. "Why?" "I don't want to cum," I spit. “Aw, why not?”"I want to fuck your brains out." Her pout morphs into a grin, and she rises from the ground, her nipples standing at attention.I take a small step toward her, and hook my fingers on the inside of her waistband. I gently tug both her. I said, ‘Tell me you want it, Erica. ‘Tell Daddy to fuck you!’ She screamed again as my cock hit bottom inside her young body, then she cried out ‘Fuck me Daddy! Oh my god, ooooh, fuck me Daddy!’ I screamed, ‘I love you Erica!’ as my cum began to boil out of me. I thrust in and exploded. Erica yelled loudly with a raspy voice, ‘Oh shit! Oh my god! You’re cumming inside me! You’re cumming inside me!’ And then she came a second time, her pussy clamping down. She wheezed and hissed ‘I love you,. All the hope ..." Her voice cracked; Brian andCharlie knew of Lucy's personal motivation. She'd watched her fatherdie from complications of kidney failure from a work-related injury,while he waited and hoped for a donated kidney that never came. She'dthrown herself into this project with more energy than anyone becauseof those memories. Even if she didn't know the first thing aboutmaking donor cells revert to stem cells or growing a bio-scaffold forthe new organ, she still did her.
