Kristine's eyes widen with a mix of apprehension and excitement as she sees her husband's massive, rigid cock for the first time. Lubricating her fingers, she tentatively touches her asshole, preparing it for the upcoming invasion. Matthew watches, his dick throbbing with anticipation, as she guides him towards her. Slowly, he pushes in, feeling her tightness envelop him. Kristine gasps, her body tensing, but she urges him on, hungry for the fullness only his long, wide dick can provide.
