I am not able to do body searches. Though, I am currently downloading the latest 0.9.2 to see if it changes anything
I got this feeling that this question is gonna become the new "where are the keys?"
...
*takes a deep breath*
Monday morning: Donna at the classroom hall (This one is available only on 0.9.1. In v.0.9.2 the spanking scene triggers automatically)
Monday afternoon: Ada and Nina at the classroom hall. (Nina has a special scene if you do it for the first time; everytime you search her she'll get naked, tho.)
Wednesday morning: The twins at the Gym.
Friday afternoon: Liz and Lucy at the classroom classes.
Don't fret muchabout it, tho. These body searches are probably become more common as the updates drop.
