"just feel it deep inside of you..." adrianus murmured, slowly and gently thrusting into them, holding them in a mating press. "feel the way it stretches you... the way it stimulates your body..."

it already felt good, but when they were directed to focus on it, they could feel their body pulsing and squeezing.

"that's right... good... just like that." he throbbed inside of them, his otherwise even breath hitching as they tightened around his cock. "your body needs this... you just need to be penetrated... stretched out... to keep the blood flowing inside there... to make sure it stays soft, to make sure that it can still get nice and wet... we don't want it to atrophy, after all, do we?"

they moaned. the idea that they really needed it, that this was something important to their health, something that he just needed to take care of for them, by penetrating them like this every day... it was good.

but it also felt like he was taking advantage of it. in the past, he would rub their t-dick while inside of them, and when he stopped doing that, he would touch their chest... but now he would only penetrate them, holding them for leverage or caressing their skin, instead of giving them any other stimulation. it felt like he was training them to enjoy just the penetration more, and to want it more often. like this was really about making them into his toy.

and it was working. they already felt close, even just from feeling him pushing deep inside of them. it all felt so sensitive, like they could feel every movement, every push, every throb. he wasn't even using much force, just rocking into them, and it still made them moan and squirm the same way they would if someone was slamming into them and touching their t-dick.

now, even when they touched themself, their fingers would wander more to their slit, feeling the wetness coming out of it, pushing inside. it wasn't that they didn't still like touching their t-dick... but they had more and more of a craving to be penetrated.

and more and more of a craving to be filled with cum, which was something that they couldn't do themself, something that only adrianus could do for them. even if they were on birth control, it did make them a little nervous to be so eager to be filled up, and to do it so often... but they were starting to feel like they needed it to be satisfied.

"mm, such a good boy..." adrianus purred. "so wet... so open... you just get stretched out and stimulated so much better with my cock deep inside of you, don't you? fingers just aren't quite enough... you need to be filled up... to feel the cum deep inside of you... so your body can stay nice and open, and healthy, and easily penetrated..."

they knew it wasn't really true, that the type of penetration wasn't that important, that having his cum inside of them didn't make it any more effective, but they were panting, the inside of their body starting to spasm. it felt like a part of them was accepting the idea of it.

"that's it... you need it, don't you? your body knows that you need it... it pulses around me so nicely... because it wants me to cum inside... deep inside of you... every day... to stretch you out... as much as possible... to fill you up... all the way..."

his pace was just a little bit faster. their body always seemed to just give in to him completely, relaxing and letting him inside, squeezing and spasming and milking his cock when he got close. it didn't feel like they could do anything but moan and take it. they stopped squirming, almost going limp as he used their body, pushing as deep as he possibly could. his movements were smaller, staying deep inside of them, only pulling back enough to make them feel it when he pushed back in.

"tell me how much you need it..." he murmured.

"i need it," they said quickly. "fuck, i need it..."

"you need my cum deep inside of you..."

"i do," they said shakily.

"you're doing such a good job... you're close, aren't you?"

"i'm so close..."

"you need it..."

they were about to cum. "i need it..." they panted.

"you're just so needy... you're always so needy lately, aren't you?"

"please..."

"don't worry... i'll fill you up..."

his hips jerked slightly, and they were already starting to cum when they felt warm, thick semen being pumped deep into their body. they spasmed around his cock, squeezing out even more of it, letting it all fill them up, until it felt like their belly was swollen with cum.

he stayed there inside them for a moment, keeping it plugged as he rubbed their stomach. "doesn't it just feel so satisfying? isn't that nice?"

"y... yeah..." they said quietly, still coming down from the orgasm.

"that's right... you needed this..."

"i needed it..." they repeated.

"very good... and tomorrow, you won't wait so long for it, will you?"

"no..." they said quietly. "i'll... i'll want it as soon as i wake up... i'll let you cum inside me as soon as i wake up..."

"good... we should do this every morning..."

"i... i wanna spend the whole day with your cum inside me..."

"that's right... of course you do... just let me keep giving your body what it needs."

"thank you..." they murmured blankly.
