Slow and steady.
Miku's eyes shot open, the sudden sharp pain forcing her to realize she had made a really big mistake.
In less than a second Sam's spear tore through her insides reaching all the way up in one single motion. Her whole body went rigid from the shock, her mind halting as it struggled to comprehend what going on. She already knew Sam's penis was massive, however only now that it was inside her did she understand what it means to have sex with him.
Sam wasn't having any better time. Miku's virgin pussy was so tight it felt like the pressure was about to crush him.
Gasping as if she had just remembered to breathe, Miku collapsed forward panting while her whole body trembled from the pain.
"M-Miku… are you… are you alright?" Sam said, slowly lifting himself using his elbows as supposed.
