Lying in bed right next to my step brother, I noticed him openly masturbating beside me. His hand was stroking his hard cock under the sheets. He reached over and started touching and squeezing my ass. Instead of stopping him, I leaned over, took his cock in my mouth and gave him a sloppy wet blowjob. It quickly turned into much more as I let him fuck me hard from behind in deep doggystyle. He used my tight pussy like his personal fuck toy until he filled me up.
