TongueLoverDamn hot, all the advice so far works. Some rimming will also make her relax and feel great.
Moritz64Really hot body and definitely ready to get ass fucked. The only thing you have to think about is that you must be totally relaxed and he has to make your asshole and his cock very slippery. Equal whether by your pussy or by lube. It may help if he makes you have orgasmn while he penetrates your asshole.
