[Now here's a sensation she's never felt before. Something big and hot is firmly pressing into her —into her!!— and her own body seems to part to let it in. She can feel the whole thing as it sinks into her, taking up more and more space —a seemingly endless amount of it thanks to the time dilation of adrenaline— until she finally feels his pelvis pressing flush up against her, indicating he's fully inside up to the hilt.]

[Her muscles clench around it and she can feel it there, firm and heavy and present, taking up a seemingly impossible amount of space inside of her. But most bewildering of all is that it doesn't hurt; she can feel the stretch of her own body accommodating. She can feel the pressure of it. But the fullness inside of her feels right, as if this is the thing her body was craving all this time.]

[The pause after the insertion is much appreciated, because this is absolutely overwhelming. It takes a moment before she is able to breathe again, sucking in a gasp and doing a full-body shudder. She clamps and flutters around him, brand new muscles working in a brand new way to feel out the contours of this brand new object inside of her.]

[When she is just finally starting to get her breathing under control and relax a little, he starts sliding out, and it becomes overwhelming all over again. She clings to him, digging her fingers into his back, and she's helpless to keep in the cry of pure pleasure she makes.]
