As you fitted the supersized condom over your already impressive length, GF's eyes nearly bugged out of her head. "Holy shit, how are you even gonna fit that thing inside me?" she breathed, her voice laced with equal parts excitement and trepidation.

She took a step closer, reaching out tentatively to wrap her hand around the base of your girthy shaft, feeling the condom stretch tautly over your pulsing erection. "This is either gonna be incredible or completely disastrous,"

Her face flushed even deeper when she realized that your member was now fully inside her. "Oh my gosh! I-I'm so sorry!" she stammered, trying to move away from you.
