Gwen's estimate wasn't wrong. After dinner her tits, although not strained to bursting by a fully replenished milk supply, still easily delivered an ample dose for my treatment. The thorough milking earlier in afternoon had also made what remained thicker, creamier and more delicious. She worked my cock with her hand again. I tried to hold back just in hope she might take me into her mouth again. She probably realized that.
"You're delicious, but I don't know if I can take a whole load again today." She looked down the bulge of her breast at my face while she continued to stroke me. I happily continued nursing at her tit.
"Don't worry, I'll be ready tomorrow." Gwen picked up her pace and I squeezed another gulp of milk from her tit into my mouth, while she brought my cock to orgasm yet again soaking her areola and nipple in a fresh layer of sticky, white semen.
Friday followed our routine. The morning dose coming first thing, welcoming me back to my stay in tit heaven. As usual her tits had reached peak engorgement overnight, the same strain that drove her to pump yesterday afternoon now eagerly delivered directly into my mouth, coating my throat in her warm sweetness, savoring the divine feeling of her magnificent huge nipples.
She worked my cock with her hands and teased it with the free nipple that wasn't in my mouth until I erupted over her tits with another voluminous orgasm. Gwen pulled her tit out of my mouth while I came and rushed to get both tits under the shower of my semen.
"It's not that I don't want it," she said reveling in the white rain of cum that covered her breasts, running down their sides and filling her cleavage in slow, viscous streams. "I just want to make sure I can take your load tonight after I've drained you twice." She shook her breasts then put her arms up to her sides, faking a boxing stance. "I gotta train up for the championship coach!"
"Oh but it's okay for me to be drowned by your morning milk load?" I joked. Gwen raised an eyebrow at me. She scooped cum with her hands down towards her nipples, building up gobs of me over her areola before finally squeezing her enormous teats which easily blasted through the cum to shower me in the bed.
"I'm sorry Jake," she turned back and forth like a sprinkler, drizzling my body. "I'll just go tell Cooper you're pulling out of the study?"
I smiled, enjoying the warm rain of milk over me.
"Okay, I'll help you train. You're gonna be a contender!"
We repeated our usual treatment after lunch. Knowing her mouth would embrace my cock again that night had me excited and I came quickly under her joyful hands before I'd even finished draining her first breast. She chastised me: "you'd better give me something to savor tonight!" And claimed the first palmful of milk and cum mixture for herself, before offering me the semen soaked breast. Unabashedly I sucked her salty nipple into my mouth, enjoying the magic blend of our fluids mingling on my tongue, until at last the flood of milk overwhelmed and filled me mouthful after mouthful.
I could feel my cum drying between us as I drank, practically gluing my face to her areola and hands to her tit. She held me into her and stroked my hair on the back of my head. I suckled away at her until she finally let go of my head and we pulled our sticky bodies apart from each other.
"I don't think I'll need to pump again this afternoon," she said, pressing her hands into her breasts in a few places to see how full her mammary glands were. "Yesterday was my treatment day so I think it put them into overdrive a bit."
"Your treatment?"
"Or I guess... it's not treatment since nothing's wrong with me. Just my dose of Cooper's drug so I keep making milk and my boobs keep making it into medicine for you."
"And you said you thought you were getting a higher dose already?" I remember a comment from earlier in my stay.
"Yeah we only see so much of each other--us nurses--but we think Cooper's trying to figure out the right dose for us right now. Some girls boobs look pretty normal. I mean no one has small boobs, but you know, like, not a crazy amount of letters into the alphabet. Then some of us are definitely real head turners... but no one seems to be busting out of scrubs like me."
"Are you doing okay with that?" I asked.
Gwen smiled at my concern, and hugged her tits into her. "Definitely! Getting engorged isn't so bad when I can look forward to having you help me. Even so I usually have some extra to pump between your treatments. But it was nice putting on a little show for you yesterday."
"More than just a show, if I remember. How often do you dose?"
"Weekly. Every day between your treatments Dr. Cooper and her interns are studying the size and productivity of my breasts. They take a sample to see how much metabolized drug is in my milk. They sometimes tune the dosing a little to try to keep me steady while I'm nursing, then in my weeks off they drop it a bit so I'm not so productive. The Thursday before I go back to work I come in and they up dose it up again to get me ready to treat a patient."
"Wow, that's seems like a lot."
"It's been kind of fun actually. I... I like my breasts. I felt pretty big when I was younger and I always felt like my breasts made me so sexy. I loved how they made guys react. Getting to feel and watch them grow to this size over this study has been amazing. I feel like I've come back each time bigger and milkier and... and it just makes me feel so sexy. So powerful. Like I said my breasts can heal like magic!"
"You really are a goddess."
"You just want to get your dick sucked tonight."
