Your mother always likes to wax nostalgic on your birthday, and this year - your 18th birthday - is no exception. She talks about all the stuff she always does: how little you were, how cute you were. It's like she can't believe you're a grown man now! Then she starts talking about breastfeeding you. You're a little shocked, but you guess it's normal...until you notice something change. She's...squirming. It's almost like she's getting excited talking about it. But that can't be, right? Your mother isn't excited by talking about breastfeeding you...right? Only she is. And its getting more and more apparent, less and less possible for her to hide it. You start to get excited, too, seeing her chest rise and fall, the way her hand brushes across her breasts as she talks, pressing against her nipples for relief from the mounting excitement...she confesses that she always found it...arousing to be breastfeeding. You watch as she slips her shirt over her head, after assessing the sizeable bulge in your pants and deciding what the next step would be. When she unclasps her bra and holds it against her tits, spilling around the sweet flowered fabric of her bra, and asks if you want to see them, you can't barely stop yourself from screaming yes, your cock straining to be free. She undresses for you, slinking onto the floor as you free yourself from your jeans, looking down at your mother as she grasps your cock with a sweet look in her eye, determined to give you the best birthday present ever.
