Now that's cocksucking. She spends over ten minutes with her lips latched tightly around his shaft, her cheeks are pursed sucking like only sluts can do. His big cock lounges in her throat most of the time and she truly enjoys his sperm reward at the end. And to top it off her hands are handcuffed behind her back, so all her sucking is done throat-fucking style with her plunging to fill mouth and throat. She really likes the feel of hard cock. She's cockmerized herself almost immediately. I assume this is role-play, she just knows her way around his cock to well. Judging from the tiny amount of jizz she dribbles, most cum went straight down her throat. She's into a cock trance at the end, good slut.
