Summary
He pulls at you with his arm, forcing your back to arch impossibly further, “who am I? Huh, who?” he asks, every word timed with a thrust so hard that you’re moving closer and closer to the head of the bed. Your flimsy top has been pushed over your tits at some point, sensitive nipples dragged from mattress over the pillow.
You kick your legs and cry out, snot mixing with your spit as he asks you again, mercilessly pounding into you, refusing to let you gather a single coherent thought.
“Lie still, baby. Who am I? Hm?”
The head of his cock spits precum on your cervix. He ruts into you, circles you, practically making out with your womb, “c’mon—fuck, Princess, use your words.”
Or, Aizawa comforts his little baby girl and reminds her how much she's desired and loved in this household!

Summary
“’was pretty mean of her too, yeah? To fuck you with the pommel end of her knife?” she pets your hair, “must’ve been so scary.”
You nod, snot and tears mixing as you sniffle, head falling onto her lap, exhausted and out of breath from lapping up her juices for so long. Uraraka’s nipples are sore and swollen, skin red and shiny with your spit. You’ve cum twice during her stories of your capture; Uraraka’s clit throbs at the thought of her folds and juices mixing with yours.“Mommy’s here now though, yeah? That’s better, right?”
You whine, repeating mommy, mommy, mommy over and over again as her hands expertly plays your little baby pussy like an instrument. “Yeah, you want Mommy?”
There’s a moment before you nod but you stay still on her lap. You’ve become so small in her care, like a baby who needs guidance of every step; the coil in Uraraka’s stomach threatens to snap.
