The tension is beginning to build within her, her body tightening around Grace's rod as it pushes deeper into her. The anticipation of release is almost unbearable. She feels her inner walls clenching around him, urging for that final push.

But just as the orgasm starts to crest, Didi lets out a satisfied moan as Grace pulls back slightly before thrusting deep once more. The sound of flesh slapping together echoes through the room, punctuating every hard, rhythmic movement.

She tightens around him, milking every last drop from him as her climax hits.

As her orgasm finally subsides, Didi collapses onto the bed, panting heavily. Her eyes flutter closed briefly, but she quickly opens them again to look over at Grace, who is still standing above her, glistening with sweat. "Grace," she breathes, her voice barely audible. "You're so much bigger than my boyfriend."

Marcus curses under his breath, looking frantically between Didi's face and where their bodies are still connected. His cock starts to soften within her, a mixture of relief and guilt washing over him as he realizes what just happened.

"I'm so sorry," he whispers, gently pulling out of her and rolling off the bed to sit beside her. "I didn't mean for it to go that far."

Didi lies there, her chest heaving with ragged breaths as she tries to process what just transpired.

"Don't," I manage to croak out weakly. "Just leave me alone right now." Tears prick at the corners of my eyes as I turn away from both of them, curling into a ball and wrapping my arms tightly around myself. "This was all my fault," I mumble into the blanket. "None of you did anything wrong."

"Oh...my God," I moan softly, my fingers tracing the length of his cock where it still throbs inside me. "You're incredible." It feels strange admitting that to him after everything we've been through, but there's no denying the truth of it now. I smile up at him as he looks down at me, a satisfied grin on his face.

"Now I just have one question," I murmur. "What made you want to be with me in the first place?"

I blush and look away, feeling suddenly self-conscious. "You know...how you felt about me before we were together."

He chuckles softly and leans down to kiss my cheek. "Oh that," he says with a smile. "I've always thought you were beautiful, but I never would have guessed how much fun you could be in bed until now. You surprised me, Didi."

His words warm my heart, and I feel myself relax into the couch beneath him.
