Susie couldn't control herself (not only was she turning into a dog but with the pink pill she was becoming a bitch in heat) she jumped on and straddled Jim and started making out. Jim under the influence of his pill and Jenny's extremely strong pheromones he kisses her back and lifts her shirt over her head. Unfortunately due to his mind and hands rapidly becoming the mind and paws of a dog he couldn't get her bra off, but fortunately they both started to shrink and slip out of there clothes. With both of them naked and overcomed by lust and animal instinct the both dropped to all fours and started to fuck like horny chihuahuas. It wasn't long before both Susie and Jim full chihuahuas body and mind; it happened so fast and they were so horny that they didn't even notice the changes before there minds changed.
Jenny stepped out from behind the corner were she was watching and sat in the chair Jim was sitting and looked out the window and saw that Mike was still having his way with his bitch and looked at the two chihuahuas going at it not noticing her. She never considered herself into bestiality before but seeing two pars of dogs going at it and the pheromones in the air her pussy was wet and soaking her panties, so seeing that no one that wasn't a dog was around she slipped down her skirt and soaked panties and fingered her wet pussy.
After Jenny orgasmed she didn't know how many times she looked down at Susie and Jim who were now sleeping still attached to each other she then looked out the window and saw that Mike was also done but though the bitch was laying down he was still up "good" Jenny said out loud. "You two have fun now" Jenny says to the two chihuahuas on the floor knowing that thanks to the pink pill every time the two are awake they would be fucking each other "but its time Mike pleases his mistress like the good boy he is" Jenny say as she shuts the door get her big boy home so she could have her fun.
