The duration depends on the swelling of the male’s bulbus glandis, which retracts once the swelling
subsides, allowing the dogs to separate. I went into the kitchen, suggesting the young ones eat their sandwiches out on the porch so the adults could talk in peace, turning to Mik, once they left, I asked if she might have another suitable dog, perhaps one a little ‘smaller’ as, noting Ben’s age, his cock and knot would likely grow even bigger…thus causing undue pain for the ‘more petite girls’. My balls were pressing against her ass before the next sound came…it was meant to be a scream but just a hoarse breathy squeak came…I held her tightly impaled on my cock a hand pushing under her to molest her clit and gash as she writhed and twisted, trying to dislodge me, my molesting fingers dragged to a nipple as she sucked a big breath in…it was going to be a window shattering scream…my fingers pinched her fat puffy nipple…fucking HARD!…the scream died in her chest and she slumped weakly…and gurgled deep in her guts.
