Stepsis promised me a deep throat

I know it's drilled up cuz she's my legitimate y.o. stepsister and all and our parents are sleeping in their bedroom as we get down and filthy in a living apartment, but I was so ultra-kinky and she promised me a blow-job for lending her money for shopping. Damn, I thought she'd only blow my bone, but we concluded up drilling as well and let me tell ya, that cock-squeezing humid cooch was worth every buck I gave my promiscuous stepsis. I guess I'll keep providing her more, you know.
