Red-haired girlfriend only experiences pleasure in the doggy style position

A red-haired friend has been saying for a long time that she needs winter boots. But words are not an extremely serious thing, but when she buys new erotic lingerie and seduces me in the evening for cool sex, then I shy away from the girl and think, if the money spent on lingerie would be enough for boots, I would fuck my sweetheart now or just licked her piston?! Ah here is such a love dialectics!
