A strand of cum and saliva connected her well-fucked lips to the tip before breaking and splattering on her tits. She licked her lips, enjoying the taste of her lover's essence, and then turned to her sister with a smile that was both triumphant and cruel.
"Mppphhh~! Slurrrrpppppppppp~!"
"See, sis?" she said in a voice that was both sexy and hoarse from the deep fucking her throat had just gotten. "That's how you do it."
"That's how you suck a real man's cock like the debased slut you are." She licked another stray drop of cum from the corner of her mouth, moaning at the taste. "Ugh, he tastes so good, and it's better than last time..."
