The Doberman stud stood with his fore-paws holding his upright stance in front of Lisa, as they both stood soapy slick, showering together. Lisa noted then two distinctly differences about her brother turned into a dog. As had her Father made mention, Jerome seemed to have grown bigger and was taller. The other noticeable difference was that when his wet, soaped sheath let emerge out his dogged cock, to Lisa it felt wonderfully enlarged.
Jeff being Jerome for a full day had bred with three different females, and had enjoyed some eleven orgasms. He had spilled such a volume of semen during one day that his Doberman dog testes had doubled their size, and increased their output.
"Oh-ah, Jerome, Jerome, your' penis, it has grown bigger, not just thicker but is LONGER..., oh but you bottomed out with that THRUST...!" Lisa said as Jerome was leaping with his hind legs, doing the forceful thrusts, making his bitch of a sister to pang for more.
Lisa was as well busily smoothing the bar of Glycerin soap all over her Doberman lover. As the soap lathered and accentuated the stout as smooth muscular body Jerome had so nicely procured when Jeff became a Dog, it worked to arouse her to near nymphomania wants for all forms of sexual sensations.
When soaping Jerome and Lisa's hands cupped his scrotum, she felt there the bulk difference of new growth. "Jerome, dear you balls, they feel so much as BIGGER..., AS SIMILAR..., to the different GIRTH... Of, your penis. You MAKE ME..., want for more so much OH... MORE, as us having sex, you with me, oh like this, THIS IS... AS INTOXICATING...!"
Jeff being as his Jerome dog half self listened and lusted deeply for wanting to thrust, as stimulate and further endear the aroused state of his horny sister.
"I, I.., never thought about enjoying sex with a DOG..., figuring that a brute male would act gruff, turn sexually mad, and like to rip my insides to bleeding. But you dear BROTHER..., oh damn but you feel so GOOD..., as oh, oh, your cumming, it feels so warm...!"
Lisa and her stud Doberman brother stood bathing under a showering of warm water while they bathed in each the lustier sexual delights. Lisa moaned with each felt hot body stream of six spewed streams of dog semen Jerome let shoot inside her womb and flooding the limited space in her vagina.
Jerome remembered with arousing delight the woman sunbathing, and how after he had climaxed in her the first time, the second load came soon after the first. He had climaxed three times inside the woman before he withdrew and as she begged him to return as stay with her, he ran away, if but to quelling, as calm his sexual ambitions.
Jeff being the younger brother to Lisa his sister, he never before his becoming a dog did he revel with any want to be especially loving toward her. Lisa was a domineering female, and tried to rule over her brother. As it happened after Jeff changed, became instead as a large, sexually inspiring Doberman dog, their relationship was kindled.
Tail wiggling, Jerome bouncing on his hind paws, feet and using his powerfully strong hind legs, he did continue his thrusting action, while taking note the showering water was becoming cooler, and the sensations he felt from his nine inches of cock stuffed deep in Lisa had her just as enthused for him to thrust, as thrust, and shove his cock deeper!
"Hey in there, don't use up all the hot water, save some for others," Father said as his voice and knocking at the bathroom door reminded Lisa she had stood being fucked then for a goodly long while.
