After a steamy session with my tight-lipped step-sis, I was eager to share my conquest with my buddy. As he admired her voluptuous figure, I teased him about the size of his manhood. Not one to be left out, my step-sis offered to help him with his problem. She eagerly presented herself, ready to assist him in practicing his withdrawal technique. As he plunged into her, she encouraged him to pull out, allowing him to gauge his control. The sight of her round, ample rear was a sight to behold, and I couldn't resist paying homage to it. My buddy took advantage of the opportunity to drill her, both of them lost in the throes of passion. The room echoed with their primal moans and dirty talk, the sight of her natural tits bouncing with each thrust only adding to the eroticism. Finally, he filled her up, leaving her satisfied and him feeling more confident in his abilities.
