Got some new idea at 08/09, let's see...
1. In the locker scenes , almost all of the action of the tentacle were "exposed", according to some anime that had some tentacle inside, sometimes the tentacle can "working" behind, such as do his job under the clothe or coved some part by girl's clothe(doesn't matter the clothe is already took off or not), leaving some reverie.
2. Whole school time can split up in 2/3 parts. The first part is normal school time, the longest time of the this three parts, plot as same as original. Second part is after school time, time shorter than the last one, the plot and the action of the school is little different than normal, usually like wearing club uniform / rush for leaving / teachers or guard become less showing up etc. The third part is night school part, normally this part is to achieve some not to be divulged things, like doing something intro / couple meeting(yes, even in girl school) / stealing etc. You can be acting very bolder at night, guards will more active at night.
3. Something you should know, "that part" can be very wet even you didn't orgasming yet (squirting may not coming with orgasming too). I know this is too detail, and the orgasming is the final goal and I know. If possible, try to make the upper leg got wet before squirting. This is a good idea if some cum left on the leg after leaving the locker and there are some cum already on your leg before your second orgasming when you been abducted again.
