In the dim glow of their bedroom, the young couple tentatively begins their anal adventure. The girl, her heart pounding with anticipation, guides her lover's thick, hard cock towards her untouched rear entrance. He applies pressure, feeling her resist, then slowly yield. She bites her lip, her eyes watering slightly as he inches in, stretching her tight hole. He moves slowly, allowing her to adjust, until he's fully sheathed. They freeze, catching their breath, then begin to rock together, finding a rhythm that sends waves of pleasure coursing through them.
