Help me find where the girl stretches her bra strap using her thumb and it hurts back.

I saw a porn somewhere, probably it is a step porn. The girl is being fucked in missionary. She is moaning "Oh yes yes yes" in a shrill tone. While moaning she is pulling her bra front strap above using her thumb, the bra stretches quite long and it sling shots back at her and she gets hit by it and gets hurt and then moans a little more. I must have seen this video 4 years ago. Please I want to find it again. I am unable to sleep until I find it. Please help me find it.
