We report on time-resolved photometries of 2014--2015 superoutbursts of AM CVn-type objects, ASASSN-14ei and CR Boo.
ASASSN-14ei is the first object which showed \textcolor{red}{WZ Sge-like multiple rebrightening phase
with a super long duration (at least 6 months).
The superhump period had gradually decreased throughout the rebrightening phase.
We suppose that the decreasing period reflects a shrinking disk.}
During the 2014 April superoutburst of CR Boo, we detected growing superhumps (stage A superhumps) whose period was $0.017669(24)$ d.
By using the superhump period, the mass ratio was estimated to be \textcolor{red}{$0.101(4)$,
which is consistent with that expected by the theoretical evolutionary model}.
