I have to say, that was one of hottest yuri lemons i've ever read for sure.
I always thought that Mei and Tsunade could make a very hot couple due to their rivalty, but this even hotter than what i would expected from this pairing. So props to you for that.

damn... that was so freaking hot! women having their genitalia stuck together has always been one of my favorite fetishes, only below of assymetrical docking, and of course tribadism.
can i ask you for a request? could you write a lemon with tsunade and kushina, where the latter has been feeling lonely and sexually frustated because she has not have sex for months due to her beloved husband minato dying during the kyubi's attack to konoha, so the slug sannin, with whom she has grown close during her mourning process, "offers" her own sexual prowess in order to help sate the lonely widow's voracious sexual appetite? as for the lemon, have tsunade and kushina start their sex "session" with some heavy kissing while their bodies are pressed together, and the sannin tightly squeezes the redhead's big and juicy buttcheeks. then, they get naked, and kushina starts to earnestly licking and sucking tsunade's massive breasts, in addition to enthusiastically fingering the sannin's pussy. then, they proceed by settling into the 69 position, and start to mutually lick their pussies. after they're done licking each other pussies, they continue their "session" by intertwining their legs and grinding their pussies together, increasing the force and the speed behind their grinding as they continue to fuck each other to orgasm. after that, tsunade uses a jutsu to produce a fully functional, very thick cock of average lenght (6.75 inches of circumference and 6 inches of lenght, look up kessia brunelly/fernanda de castro for reference), which she uses to penetrate kushina's pussy, who rides tsunade's cock in cowgirl position until the sannin cums hard. to finish up their sex "session", tsunade orders kushina to lay on her stomach on the former matrimonial bed, to which the redhead happyly complies, and the sannin, with her back to kushina and looking away at the opposite side, proceeds by positioning herself above the redhead's ass, inserting her ultra fat cock into the lonely widow's asshole, stretching it wide open in process (if you need visual reference for this position, look up for the reverse prone bone position, and if you need to see this sex position in motion watch the sex scene with mandy mitchell and alysa gap), before plunging herself deeper into kushina's rectum, which makes the redhead gasp loudly in pain and excitament, and starting to pump into the widow's asshole with growing force, as she lays on her stomach herself. half an hour later, tsunade cums harder than ever before in kushina's bowels, which makes the redhead's anal walls tightly clench the sannin's super fat cock and close around it, making both women moan very loudly in unison, as they're overwhelmed by their mutual orgasm, which makes their minds go blank from the sheer pleasure they're experimenting, all while they on their stomatchs panting and covered in sweat from their lengthy sex "session", stuck together until cock jutsu wears off some hours later.
that's my humble request for you. i hope you can take it.
