Play along.

With a hard-on as big as yours was, there was no way you could turn this down. Mother or not, she was a goddess and you will make her your own.

While kissing around, in this tomb of bosom, you reach round and squeeze her cushy behind; a signal, used by your father, to her to get ready for fun time.

Giggling a little, she pulls your boxers down, which fall noiselessly to the ground, and delicately takes holds of your raging erection.

"Whoa," She exclaims, near forgetting to keep her voice down, " You're really excited, honey!"

Leading you by your groin, she backs up to a clear counter, hops up on it and lies back. While you're no longer covered by her nightie, her towering bust prevented her from seeing you over it and required both her arms to keep steady, without the help of a bra.

"Take me, my stallion." She moaned, longingly, raising her legs up onto the counter, before spreading them wide.

Her pose left no secrets with her long, slender legs leading, across the silky skin of her inner thigh, down to the glistening, overflowing honey-pot of her womanhood. The thick, wet covering of brown pubic hair is the last shred of modesty between you and her under-lips.

Sliding smoothly into her depths, taking you right to the hilt, her natural lubrication coating your whole shaft, in warm, sticky layers of her juices, you start pumping in and out of her, while she pants in sync.

Even after two kids, her tunnel was tight, as ever, squeezing and massaging, oozing all the love fluids she can muster.
