Maria Pavlova, Part 3
"All this kissing made Tom beg me to make love and give him some relief, but I always said:"
"'Sorry, dear, we have to wait until the end of the night, since I don't want to spoil the data by altering the conditions of each kissing trial. You understand, don't you?'"
"But making his cock get hard and then icing it down again over and over caused him to become incredibly horny, and we found that the readings increased during each night if he didn't cum the night before."
"We solved that problem by only trying one lipstick each night, to leave time for love-making. This spread the trials out over a longer period... So soon this routine became a habit: every night I'd put on a particular lipstick, we'd kiss until he wasn't getting any more excited, and then he'd jump up to take a reading on the hardness meter and I'd record it. Then if the reading wasn't very high, I'd change lipsticks to one that was already known to be more effective, and we'd make out for a long time, just to be sure he was really worked up, and then we'd make love. And usually I'd make him cum, since I wanted to still reinforce his addiction to my pussy."
