The tab came off

Now she had a barely noticeable zipper on the back of her head without a tab, she would not be able to remove the mask because it fits her face very tightly. You have an erection again.

You went to the box and took out a second mask with holes for the eyes, it was without a zipper. And then you crawled up to your sister and started putting the second mask on top.

"Wow, mind you, I didn't tell you anything… But I like the way you think... ha-ha-ha" - a voice rang out in your head.

The mask was not so dense, and therefore you could easily put it on your sister's head. You also hid the edge of the mask under the collar. And then you aligned the eye holes roughly where her eyes were. Except there was blackness behind them, and that turned you on, too. Now she is almost a faceless woman in black. Great cosplay for a thief.

You couldn't stand it and started kissing her through the mask. She started squirming and then she got up with your help. She rubbed her eyes and then looked down at her hands. She ran her hands over her new nylon face, and pinched the fabric a couple of times. She looked at you while continuing to stroke her face.

"Listen, I do not know who is in front of you now, your sister or mine… I personally can't say anything yet."

She lowered her leggings and then her panties. Unexpectedly for you, she pushed you to the floor and straddled your erect penis. She grabbed your mask off the floor and started pulling it over your head. You almost didn't notice how she had already finished, because you were completely engrossed in sexual intercourse. She aligned the mask so that only your blue eyes were visible now. She took you by the cheeks and kissed you on the lips through many layers. You hugged her and started moving even faster. You fucked, hugged and kissed like that for half an hour until both of you were exhausted after sex. Your seed was leaking out of her pussy again. This time she didn't put it away, and just put her black panties and leggings back on.

When suddenly the front door began to open.
