My senior teacher, Jun-sensei, is usually neat and pretty, and popular with students. But I know a secret about this wonderful teacher! I told her that she is a cosplayer who does photo shoots as a hobby! I called her to her house and requested her to wear a perverted cosplay costume, on the condition that she keep quiet. I reluctantly changed into her clothes, but Jun-sensei started to play with me... "I'll do something nice if you keep quiet," she whispered, seducing me with her live cosplay costume! I couldn't resist the perverted cosplay costume that suited her fair skin and finally... Deep blowjob, cosplay sex, body washing slut technique mouth ejaculation, vibrator masturbation, continuous creampie FUCK with a huge cock... a total of 8 angry shots. I was supposed to get a hold of the senior teacher's weakness, but I was completely toyed with and the slut blame exploded. A 150-minute story.
