Beg to suck her cock while she fingers you

"Feels so good," you moan. "Please, let me service your cock while you finger me."

"Yeah? You wanna see Mama's dick?" she asks. She moves around to your side, one hand reaching back to keep fingering you. Her cock appears in your peripheral vision, and you lean closer to it. Her erection is nearly a foot of majestic black dick that puts your sorry little penis to shame. It juts out from beneath the hem of her dress.

"So big," you mutter, sealing your lips around her shaft. The feeling of her fingers up your ass and a fat cock in your mouth is wonderful.
