Unlocking the apartment door, he let himself in and was immediately startled by the scene in Beth's front room. A slim girl he recognized as Tanya was bent over the arm of a chair while a tall, hardbodied black man pounded her pussy from behind. They didn't seem to notice Mark and Blake continued thrusting into his little blonde lover, stretching her pussy around his thick black cock.
Tanya's perky little tits bounced with each thrust from her lover and Blake picked up his pace, fucking her faster until finally burying his long, hard cock deep in her pussy and releasing a flood of hot cream inside her.
Mark was stunned and confused, and Blake just laughed when he saw the look on his face. "Hey, Mark. Ready for tonight?"
Tanya moaned happily and swayed to her feet. "Oh, Mark... let me explain..." She made some quick adjustments with the Chronivac and set the device to turn Blake back to Beth. Showing Mark would be much quicker than explaining, and seeing is believing.
