The sister she introduced for the first time is a NEET, a so-called 'mourning girl'! She seemed like an introvert, but once she got into the kotatsu, she started bold actions! Even though she was nearby, she reached out to my dick and forced me to jerk off! She hid in the kotatsu and inserted it on her own. Pretending to be calm, she pushed her bare ass against me and tempted me to have unprotected sex! Had she been suppressing her sexual desires all this time? Without her knowing, I went for a second round!!
