Mark chuckled and nodded as she pulled her panties down, "Oh yeah, that's the one." His cock was hardening already in his pants and his hand stroked higher... brushing her folds before the light changed and he had to pull forward again, "God, I want to fuck you right here." he said as he reached back over and pressed his palm against her inner thigh, "But, we're almost there." he said and slowly moved his hand higer until he palmed her bare sex and traced his middle finger along the folds until he found her entrance and felt for wetness. "Tell me what you want to do Trish?" He wanted her to say it, to confirm that she wanted to cheat on her husband... "There's a nice little shop up here, want to shop for a toy?" he asked with a mischievous grin, teasing her playfully as he began to work his finger in and out of her pussy.
