Most ladies aren't available last minute nor do they choose to work past a certain time. With advanced scheduling, most times can be accommodated.

Most importantly, you were really vague in your request by not listing your preferences. Description of a lady you're looking for, length of session, and type of session should be mentioned. Were you looking for a college brunette, a redheaded MILF, or other? Were you looking for FBSM, GFE, or BDSM?
