[PLOT SUMMARY]
Sanae Tanemaki, a brilliant science major struggling with her future, suddenly grows a dick!
Her healthy young penis immediately becomes erect and releases massive amounts of cum, turning her into a masturbation addict. She degenerates so much she spends entire days jerking off in her dorm, but her remaining intellectual curiosity sparks an idea.
“I’ll research my dick!”
She records its progression from soft to fully erect, pursues the perfect ejaculation through squatting exercises, and becomes intoxicated by hands-free orgasms on camera.
Then her college friend Chizuru visits and finds her mid-ejaculation. Seizing the moment, Sanae drugs her with sleeping pills.
Faced with Chizuru’s defenseless body, Sanae can’t control herself and uses her friend as a masturbation toy, violating her relentlessly before achieving her cherry-popping creampie.
As Chizuru’s consciousness returns from the internal cumshot, Sanae administers a “super potent aphrodisiac”—a guinea pig breeding drug that instantly puts Chizuru into heat.
With swollen nipples, gushing fluids, and forced ovulation, Chizuru welcomes the dick. Sanae doses herself too.
Their erect shafts and swollen testicles fully aroused, the two college girls transform into breeding animals, driven only by instinct.
Violent kissing and breeding presses with zero affection and 100% lust!
Back-to-back creampies with unrelenting pistoning!
Choking and dominating the female’s body and mind!

Editorial Review
Sanae Tanemaki’s *Dick Research Lab* occupies the intersection of transformation erotica and coercive fantasy—a niche that’s grown steadily within the futanari doujinshi space as artists push past conventional power dynamics into explicitly non-consensual territory. The work sits comfortably alongside similarly ambitious titles that weaponize scientific framing as narrative scaffolding for escalating depravity.
What distinguishes this 81-page full-color work is its commitment to psychological degradation as the core erotic throughline. Rather than treating the protagonist’s sudden futanari transformation as incidental, the narrative uses it as a catalyst for systematic self-destruction: the progression from isolated masturbation addiction to predatory behavior against a sleeping friend mirrors a deliberate descent mapped through increasingly extreme aphrodisiac experimentation. The “no-hands squat masturbation” and drug-induced scenarios aren’t merely shock elements—they’re structural pillars supporting a fantasy of complete loss of inhibition. The ahegao and mind-break tags suggest heavy emphasis on visual presentation of sexual overwhelm, while the college-student setting grounds this in a relatable social space before obliterating that relatability through coercion.
The drug use framing (both self-administered and weaponized against the friend) is notable; it reframes consent collapse as chemically inevitable rather than volitional, which carries specific appeal for audiences invested in powerlessness fantasies and corruption narratives.
This is targeted squarely at readers seeking futanari content that doesn’t hesitate at dubious consent, who value the marriage of scientific aesthetics with unrestrained sexual chaos, and who appreciate explicit psychological transformation as erotic substance. If you’re drawn to transformation erotica that treats taboo-crossing as feature rather than bug, this delivers thorough commitment to that vision. For those seeking futanari work with negotiated intimacy or mutual pleasure as focus, this isn’t your entry point.
