บท 57: A volunteer (2) (R18)

"UHH~~" Fiona's body trembled as she let out a sudden moan, taken aback by the unexpected size of my penis intruding into her inner walls. Nevertheless, she persisted with her lecture. "Now that you have entered your partner's vagina, begin moving your penis in and out slowly. This will widen her vagina, making it easier for you to reach her womb and release your seed inside. And when you are done, please remember to wait a few days to confirm if your partner has gotten pregnant or not." As Fiona finished her instructions, I had already fully entered her constricting fleshy walls and was kissing her womb, eliciting a loud cry from her lips.
