Ever since Sherlock made the "real baby" comment at their wedding, John and Mary both haven't been able to stop thinking about it. First they would joke about it, and then it sort of escalated into dirty talk.
When they find out that Sherlock is all for it (though he's repressed the kink quite a bit), they are eager to invite him into their bed as their "baby."
Bonus points for Mary "breastfeeding" Sherlock, Sherlock using John's cock as a dummy, and bathtime.
Get as kinky with it as you like; this anon has no problems with watersports/diapers, although I would prefer any scat be at least treated with less graphic detail, and I would prefer to stay away from noncon (although dubcon aspects are A-OK with me).
John/Mary/Sherlock, ageplay/infantilism, warning for incest roleplay
