X-Mentor - (F/F or TS/TS, Bondage)
This will be either a continuation of the game I linked to or a complete restart with lesbians. The synopsis below is an elaboration of the original story. However - if you wish to restart and start earlier, we can begin with Shamus' powers being detected.
Shamus O'Rielly arrives at the X-Mansion after a souped-up Cerebro detects her. Luckily for her, another student with the same powers as her already resides at the X-Mansion. Thus, the current student takes Shamus under her own wing mentoring her.
