" Be more careful." Yes, Dear." I embraced her being careful of her arm. I went into Jenson's old office. I helped my prisoner out of the chair and cu...ffed him. "We are going to ride out to that farm and clear it out." I don't think he was happy but I really didn't care. We left moments later with Jorgie holding a pistol on the guy. On the way over, I said, "What's your name?" It's Mark Johnson." Well, Johnson, we are going to clear that farm completely. You're going to help." You can't do that. ."I groaned."...Going under the blanket..."I groaned again."And wrapping my mouth around that...Nice...Hard...Cock."She whispered, squeezing my dick in between every word."Would you be alright with that?If your big sister sucked your perfect cock?" Please." I practically begged.She giggled again."Since you asked so nicely."She slowly lowered herself under the blanket.Nothing happened at first, but then I felt her slowly wrap her wet lips around my dick.I thought I was gonna cum right there.She. How we would have fared had I chosen any of the other rather more exotic options in Alfred's programme could be anybody's guess. In retrospect we all understood the complexity of our fumblings, realised that what we had done was beyond anything ever attempted by man. Alfred was the first to admit that he probably would not have attempted it, would rather have disappeared in an unmarked grave or ended up as a corpse on the slab in some anatomy class, had he perceived all those ramifications. I watched all three ladies. Sarah and Jill working on Beth’s body, and Beth writhing in pleasure as she sucked my cock.I was ready to explode, but no one had said whether part of the lesson was to have Beth swallow.I made it clear to all three that I could not hold back anymore. At the last second, Beth pulled my cock out of her mouth and arched her head back. Just as she did, I shot my gooey load. Beth did not learn how to swallow at her first blow job that night, but she did get to experience.
