Liz slightly opened her eyes and made contact with me. She saw me there with my mouth wide open not believing what I just did. Instead of getting shocked or getting Jon's attention she stared at me with her eyes glazed over in lust. Most likely Liz saw my raging hard on pressing against my tight jeans. I was hard from observing Jon's ass pump up and down. Liz's eyes suddenly shut and she began to grunt and moan as Jon transported his hot jizz from his cock to her cum starved cunt.
