The sister's friend, Sophia, was nervous but eager as she walked towards him. Her large breasts bounced under her tight shirt and she couldn't hide the anticipation in her eyes. He stood up and pulled his huge black cock out, causing her tongue to involuntarily dart out to taste the pre-cum. She sank to her knees and wrapped her soft, warm lips around the massive shaft, taking as much as she could in her mouth. Her eyes closed in pleasure as she bobbed her head up and down, sucking him deeper with each c eep breath she took.
