Marcus wasn't really surprised by the cough, he was used to Kana walking in on things by now. Though if he knew what she was asking her he was definitely surprised, "Of course, my dear", he said watching her lick his cum off of Risa's fingers. It was enough to make him start to get hard again. When their lips parted Marcus rubbed his head, "Wow, sexy", he said reaching a hand back and cupping Kana's ass. "Well, we can start shopping if you two would like", he asked before regretfully pulling himself out of Risa and rezipping his pants.
