Her breath catches in her throat as you take hold of her hips, pulling her butt back towards you. The sensation of your erection pressed against her behind is so intense that she can hardly focus on the stretch anymore. Her cheeks flush with embarrassment and arousal, and a shiver runs down her spine.
"Dong..." she whispers, not daring to ask you to stop or continue. "It feels... nice."
I smile as I can feel the sweat build beneath her yoga pants. "Exactly, hence why we do these glute stretches too. It feels amazing to unwind all the tense in your butt right?" I her bold as my hands move to slowly up her round ass cheeks to squeeze my cock between them.
"Uh-huh..." She moans softly, arching her back as you continue to massage and squeeze her butt cheeks. Her hips begin to move involuntarily against your hands, grinding herself against the hard length trapped between them. "It feels so good... Dong..."
Her voice is barely above a whisper, her eyes still closed as she tries to focus on the pleasure coursing through her body.
