It was surprisingly not as fun as I would have thought. Maybe that was because of the weird face I was making, or maybe because of the mesh shirt creating some friction on my face. It got more fun when Sarah manoeuvred one of her tits into my open mouth and I could feel her hard nipple brush across my lips. I sucked in just slightly and her tit pulled away with a soft resistance from the suction. Her other tit and nipple were in and out my mouth soon after, and she traded tits back and forth a few times before pulling my entire face back into her cleavage...
