Although you were eager to get back into the action, you decided to take a moment and peek in on Erika and Mary by using the app to create a sentence for Mary.
"This multibreasted housewife is stroking one of her wife's cocks vigorously."
Thinking about it, the only change she received so far was a few more breasts, giving her barely anything to keep up with Erika's twin cocks and extra breasts, let along her own tits. Thinking over the various mytholohical creatures you had used in your erotic writing before, you realized that a certain sea monster would make the perfect transformation for Mary to overcome this problem.
"This multibreasted scylla is stroking one of her wife's cocks vigorously."
As tempted as you were to see for yourself how the woman looked with the lower body of a giant octopus, part of you felt like you should let the couple have some more time together without intruding. Moving on to the next family member, you picked Susie, who should be hanging out with Charlie right now.
"Susie is frotting her dicknipples with her identical doppelganger."
Chuckling to yourselves, you quietly remarked, "Well, looks like they must be on better terms again." Compared to the previous statement, this one felt much more limiting since half of it dealt with your own daughter instead of Susie. Though it seemed like you could maybe change the last word in a way that would still affect Susie, you chose to play it safe and alter something else. After a bit more thinking, you changed the word "frotting" to "stretching", hoping that things would work the way you envisioned.
Meanwhile, reality was overwritten such that Susie was no longer rubbing her dicks against Charlie-turned-Susie's matching pair. Rather, she was sitting on her fake twin's face and getting eaten out while her nipplecocks bent and stretched all the way to penetrate Charlie's vagina and anus simultaneously as if they were elastic.
Continuing down the list, you targeted Sarah for the next sentence.
"This student is kissing herself and masturbating while thinking about her friend's numerous extra body parts."
Realizing that she was forced to masturbate because you left her alone to take care of your own business, you felt a pang of guilt. However, the "numerous extra body parts" mentioned here had you thinking that you might have a great opportunity to make up for your absence. You had no way of knowing who this "friend" of hers was, but it honestly didn't really matter much. Settling on what word you wanted to change, you edited the sentence to read:
"This student is kissing herself and masturbating while thinking about her own numerous extra body parts."
After hitting confirm, you decided to have two of your bodies head back to Sarah's room to see how she had transformed. Knocking on her door, you heard a trio of identical voices call out in harmony, """Come in.""" Accepting her invitation and entering the room, your jaws dropped at what you saw. Laying on the bed was a girl who looked exactly like you did when you were eighteen years old, except with your current three-headed, multi-limbed and hermaphroditic form.
"I was wondering when you were gonna get back," Sarah remarked with her middle head. Switching to speaking with both her lipples in unison, she asked, ""So are you just gonna keep standing there and staring, or are you gonna get over here and pick up where we left off?""
Once the surprise wore off and you were having a great time with the energetic, younger version of you that Sarah had become, you proceeded to target the last remaining member of her family, Erika.
"The hermaphroditic scientist is getting screwed silly by her scylla wife."
While you already knew that you wanted to turn her into a monster girl as well, you were having trouble choosing between a lamia and a hydra. In the middle of your deliberations, your train of thought was interrupted by the sensation of your dicknipples cumming on both clones that were in Sarah's room. After each of your bodies finished splitting into three copies, a crafty idea popped into your head. If it worked conjugating the word "dick-nipple" previously, who was to say you couldn't hybridize other nouns or concepts the same way? Your conundrum seemingly solved, you replaced the word "scientist" so that the statement would read:
"The hermaphroditic hydra-lamia is getting screwed silly by her scylla wife."
Wanting to be present for this change, you waited until after you entered the master bedroom with four of your bodies before pressing enter. As the new reality superimposed itself upon the world around you, Erika suddenly turned into what could best be described as three snake women conjoined from the midpoint of their snake half down. Each of her three torsos were carbon copies of her previous two-headed, two-dicked, six-breasted and six-armed form. While two of her upper bodies were kissing and groping each other, the third was wrapped in Mary's eight tentacles. It was clear that she was almost ready to cum, judging by how wet the tentacle sliding in and out of her pussy was and how much precum was leaking from her tentacle-wrapped cocks.
Moments later, both penises erupted with a thick, double-barreled shot of cum that landed all over her wife's quintet of breasts. What happened next, however, was incredibly fascinating to watch. Much like whenever you multiplied, Erika's middle torso began to grow wider before starting to pull apart into two halves from the top down. Regenerating as they moved further away from each other, the split continued all the way to the junction point where her snake halves met and joined into one large tail. Upon finishing, Erika now had four upper bodies, illustrating that the hydra part of her new species functioned as more than just a pretense for conjoinment. Turning to look at you with one of her new heads, the lamia stated, "Took you long enough. Now get over here and show me how glad you are to move in with us."
"With pleasure," you responded in a sultry voice as you advanced upon the mythologically-transformed couple, your dicks already rock-hard.
