1> Both seme and uke are working adults.

Seme forces the uke to be tied up under clothing and vibrator inside him and makes him attend a meeting
uke is afraid of being discovered while in meeting and i think seme either watches him or comes up witht he excuse he is not feeling well

Possibly extra or gag of him being found out by other in meeting and guy being the same or something << Kichiku MEgane

2> Older seme and younger uke
Seme always was looking after uke when they were younger
Uke had habit of bitting fingernails
Seme moved or something or uke did (not so sure on this part)
Uke reunited with seme
Uke became stressed or upset while starts to bite finger nails so Seme stops him and washes uke hands or checks if he hurt himself
Seme is possessive of uke, possibly thinks uke was his since they were young

Any help is much appreciated
