I Nursed My Sister's Milk

My younger sister just had a baby. We've always been close, shared a bedroom, shared secrets that only sisters will share. Anyway, I came over to visit her recently. The baby was napping, so we sat in the living room have a nice chat. She was wearing stretch pants and a t-shirt, no bra. She's got big tits, unlike me, and now that she's nursing, they are very big. Her engorged nipples were visible against the cotton fabric.

As we're chatting, I noticed her breast has begun to leak milk. There was a growing wet spot on her t-shirt. I mentioned it to her (she hadn't noticed yet) and she goes, "oh damn, my milk is coming out and the baby is sleeping." She didn't have a container available to express and save her milk, so she was about to get up and express into a glass. Half-joking, I tell her to let me help. She gives me a look that says "no way" but then says, "what the hell." So, she peels off her t-shirt and I see my little sister's boobs for the first time since before her pregnancy, and they are enormous with large, brown areolas and thick nipples. I got this unexpected tingle, but didn't say anything. I knelt in front of her and held the leaky breast and began to suck. I couldn't believe how sweet her milk tasted.

But the position wasn't comfortable, so I lay down on the couch and put my head on her lap and nursed that way. My sister looked at my face and noticed I was kind of flush in the face. So, she asks me, "is this turning you on?" I blush even more and nod. Her nipple was like a tiny cock in my mouth, erect and pumping milk into me. She smiles and tells me to take care of myself. So I slid my hand in my pants and begin to masturbate as I continued nursing her. I was so turned on by now, and it was so unexpected that it didn't take long and I had an orgasm. I smiled and said she had amazing tits.

When I finished nursing both her breasts, my sister said, "now it's my turn." She lay back on the couch, pulled down her stretch pants, opened her legs and began to masturbate. I watched her get off and then made some coffee. Since then, we've done the nursing-masturbating thing several times. Gotta love having a sister.
