Stumbling upon my husband in the tub, cock in hand, was a shock. But seeing his massive erection, I couldn't help but join in. His eyes widened as I lathered up, slowly stroking his thick shaft. He groaned, his hips bucking as I expertly worked his cock, my big natural tits bouncing in the water. His breath hitched, and I felt his body tense before he explode, his huge cumshot coating my tits and hands.
