Wild Night with My Poly Partner

Last night was one of those rare nights when my girlfriend and I both felt the urge to explore our limits. We've been in an open relationship for a year now, but we still crave each other's bodies like no one else's. She came over with her latest toy, a vibrating butt plug, and suggested we try something new. I loved how she was so adventurous and ready to take charge. We started off slow, kissing passionately on the couch as her fingers slipped under my shirt. Soon, it escalated into us both stripping in record time. Her hand wrapped around my cock, guiding me closer to her pussy while her other hand held the butt plug steady. I lubed up and gently pushed the toy inside her. Fuck, she was so tight. My fingers found her clit as I thrust harder into her pussy. The vibrations were driving us both wild, each moan echoing off the walls in our little love nest. She leaned back onto me, arching her hips to meet my every stroke. I flipped us over and lifted her legs up against my chest, pounding into her from behind while she rode the toy deep inside her ass. The slick sounds of flesh meeting flesh were so loud in that moment. We both came together, gasping for air as I emptied myself deep inside. We lay there afterward, breathless and covered in sweat. She asked if it was weird to want more than just one partner but still be this connected with me. Do others ever feel like their open relationship is lacking?
