Teresa, feeling the weight of her dare, tentatively reaches for the intimidating dildo. Her friends watch, holding their breath as she applies lube and tentatively presses the head against her tight, virgin asshole. She gasps, her body tensing as she pushes, feeling the thick shaft slowly stretch her open. She moans, her eyes fluttering as she takes it deeper, her asshole gripping the dildo tightly. The room fills with the sound of her pleasure, her friends cheering her on as she fucks herself with increasing urgency, the dildo glistening with her juices, her body shaking with the intensity of her first anal orgasm.
