I had been lactating for a few months, thanks to a strict regimen of induction. My breasts were constantly full, and I loved breastfeeding my husband. I quit wearing a bra so he could always get at my nipples. They were always sore, but getting suckled soothed them, so I often went without a top at home as well.
One day I had on a thin white tank top. Jim, my husband, hadn't nursed in hours and I was getting so full I started leaking. He squeezed them a little, soaking my top, my nipples were poking through and completely visible through my now see through top.
When his friend came by right then, I was embarrassed, Jim insisted I not change. After two margaritas I no longer cared, or noticed, but my tits were still full and achey.
We were watching a movie, me between them on the couch. Jim reached over and pulled down my top, my big nipples spilled over the top. He ran his fingers back and forth, making them stand up and harden slightly.
He started telling his friend how sore and in need of a nursing my tits were, that he'd be helping me if he nursed me. Jim nursed for a moment, I moaned as his mouth filled, and with milk dribbling down his chin, lifted my other breast towards his friend.
The next thing I knew they were both latched on, suckling, moaning, drinking from me. I felt my panties fill with wetness. They drank from me until my tits felt deflated. Jim said I should thank his friend for helping, and pushed me towards the floor. I got down on my knees and drained their cocks.
I've been nursing them ever since! My "baby boys"!
