It was Tuesday evening, and Mackenzie pranked her stepbrother, Johnny, by taking him on a wild goose chase. She actually led him to believe that he has a secret admirer. This admirer supposedly left instructions for him all over the house, and if he followed them to the letter, they would lead him to her. Mackenzie got the poor lonely guy to follow them all the way out to the garden and to, well, pull his pants down and jack off. Johnny boy did everything that was asked of him and jacked his cock outside until he was ready to ejaculate. His stepsister appeared from the bushes with a water gun and her phone. “Smile! You’re on candid camera, bro!” Johnny was shocked and embarrassed. Mackenzie realized she overdid it a bit and decided to make the poor guy feel better. She took his penis out and sucked it right then and there. The guy was a bit stunned but didn’t shy away from the opportunity. After all, he had been looking at his stepsister sexually for quite some time. The sexy teen girl got on her knees and made that fine cock really hard. She slurped and gaged on it for a while before she got on all fours and offered her asshole and pussy to him. The pussy seemed to suck at his penis as it slid into her vagina. The guy massaged her anus fucking her pussy balls deep. She just pushed her cute little ass harder onto him, making him fuck her faster. His big cock spread her tiny pussy wide, both in doggy and in cowgirl. Skinny naked girl moaned and screamed out loud as that throbbing dick reached her uterus. She got off the dick and turned to face her forbidden lover. He spread her legs and fucked her in missionary. What a sexy skinny figure with sexy long legs! Wow! As he admired her finely trimmed pussy hair, his naked stepsister started moaning and begging him to feed her some cum. She wanted to taste it so bad that, and she did, as soon as her stepbro ejaculated right in her face. Guess the joke was on her.
