have been discussing a lil' bit about how Lemon and Blacklight deal with their sex lives since Black is disable (she has a spine injury she received in her childhood).
Lemon's 'talent' is motherhood, making her a HIGHLY FERTILE pony, but this also implies her estrus is WILDLY INCONVENIENT. And by that I mean they are INTENSE and leave her needing attentions for a whole week, where she can't help but leak and rub against whatever she can to relieve herself. Sadly Blacklight can't always attend to her mare, since her chronic pains often spike exactly at the change of the seasons when estrus affects her spouse, so the unicorn often leaves Lemon in the care of her closest friends. And those friends happen to be Strawberry and Raspberry, the horniest mares of Jolly Bay.
Blacklight ain't into cucking, but I feel it may be inevitable that the poor gal will once in a while find herself witness of the aftermath of her wife's sexcapades.
of course it's all done in good fun and consensualy.
