Suck.

You wanna suck on her finger but she pushes them deeper, making you gag and your eyes tear up. You're not given the time to adjust as she presses against the back of your tongue with three of her digits, making you retch again, and again and again.

Your mouth produces even more saliva, coating her digits in your warm slick fluids.

"Spit it all out! In my hand!"

Martha commands you and withdraws her hand from your mouth. She presents it before your mouth and catches the string of spittle that dribbles from your open mouth. You cough and gasp.

"Good boy! Spit it all out! Keep your mouth open!"

Her command sounds lewd in your ears. You try and do as she tells you and let more saliva flow.

"Such a good boy! So good! Stay!"

Martha commands you to stay still and moves her hand with the wet and dripping fingers between her thighs. You can' see it, but she coats her shaft with the warm fluid from your own mouth. The slick noises reach your ear and you feel her hard member against your ass.

As you feel her finger between your cheeks and on the entrance to your butt, you instinctively move away from her. Martha's other arm around you squeezes your chest tightly, drawing you even closer to her chest. She bites your shoulder.

"Where are you going?"

She proceeds to wipe her wet fingers between your ass cheeks. She licks your shoulder until her tongue reaches your neck. As soon as it is there, she bites your neck too, while drawing circles over the entrance of your ass with her finger.

She whispers in your ear.

"Why is your mouth not open? Did I say you could close your mouth, stepbro?”
