Directed US schoolgirl to accept kiss (5)
I believe the answer is:
coxed
'directed' is the definition.
(acted as a cox on a boat)
'us schoolgirl to accept kiss' is the wordplay.
'us schoolgirl' becomes 'coed' (I've seen this before).
'to accept' means one lot of letters goes inside another.
'kiss' becomes 'x' (X can represent a kiss).
'coed' going around 'x' is 'COXED'.
(Other definitions for coxed that I've seen before include "Having a helmsman" , "Steered (a rowing boat)" , "Guided, say, four" .)
