Well, we do it when we hav the opportunity... sometimes in
between lessons when she comes to my hostel room...
The best time is when both parties need it, doesn't matter it is
day or nite.
Once during lecture, she wrote on my notepad "I want you", and we
slipped away from the backdoor to my room and make love...
Guess if it is mandane...morning or nite...or too predictive...then
it will spoil the fun / thrill of it.
