You stick your dick in your mom's ass

You decide to try out your mom's asshole. You have your mom get into position on her hands and knees in front of you. She thinks you're about to penetrate her cunt again, but then she feels you against her anus. "Is he really going to do this?" your mom thinks as you press harder against her sphincter. "Is my own son going to butt fuck me?"

Your mom knows the answer to her questions is "Yes," and what disturbs her is how excited she is about it.

You mom has never had a dick in her butt before. She hasn't had much of anything in there really, so as you begin to push deeper insider of her - mercifully stopping to squirt some lube - she doesn't know what to expect.

You mom's anus feels great for you. While your mom's pussy is pretty loose, you know from giving birth to you and whatnot, her asshole is pure virgin territory. You mom's asshole is even tighter than Emma's now that you bang your girlfriend in the butt so much.

Beyond the pleasure on your cock, it's just simply exciting to have turned your mom into your anal slut - and you can tell from her moans that she completely is. This is the woman who controlled your life for 18 years - gave you a curfew, punished you, etc. Your mom **** you to eat foods you didn't want to eat and go places you didn't want to go. Hell your mom spanked your butt! Talk about karma, you think as you pull you cock out all the way just to penetrate your mom's asshole again.

All a mother wants is what's best for her children, right? For so many years your mom did what she thought was best for you. She provided for you. In recent years her heart has been a bit more empty because you didn't need her the same way you used to. But now, as she feels your cock sliding in and out of her bum, she's providing something new for you - something completely special that she's never shared with anyone else. I love my son, so much, she thinks.
