Entering wifey's ass

I kneel down in front of wifey, and take my cock in my hand and start moving it towards her ass. I can tell that wifey is nervous, but she is doing her best to smile towards the camera.

The tip of my cock touches against wifey's asshole. I feel her flinching a bit, but to the camera she says:

"There's a first time for everything."

I start pushing into Wifey's ass, but her sphincter is very tight, and she is very nervous, but slowly I increase the pressure and the tip of my cock enters Wifey's ass.

Wifey throws her head back, her face twisting in pain. I pull my cock out, but she whispers:

"Keep going."

I again push my cock against her ass, push the tip in, and then keep pushing until my cock is halfway into Wifey's ass. Wifey is twisting back and forth with the pain from her ass being stretched, but she keeps whispering "keep going" so I push into her ass until my cock is all the way in Wifey's ass.

Wifey breathes deeply a few times, then manages a smile for the camera, and says:

"Wow, so this is how anal sex feels like?"
