In which Monmouth demonstrates the fine art of gift-giving:

For her 40th birthday, I gave Betty a belated present: A shiny, black hand-poured silicone buttplug, tapered in shape, with a generous bell end at the bottom, just above the recess.

It was destined to fit snugly into her tight, pink anus.

…

I smeared some lube on the puckered opening of her ass, and buried my cock again in the wet depths of her pussy. Betty pressed back against me, driving herself onto my hard shaft, and I slid my thumb experimentally into the lubricated tightness. She let out a deep groan.

“Fuck…” she muttered, and I pulled my thumb out to reach for the plug. Teasing her, I slid it down the slippery crack of her ass, down to the waiting anus, and began to massage her with it, gently. With one hand on her hip, I kept her still, just the tip of my cock still inside her, and pressed the tapered smoothness of the buttplug against the resisting muscle.

“Open up,” I purred. “Show me how you take it in your ass.”
