I once spent some time with a young lady in an exotic place. In any case we were having sex and she was on top and laying on top of me. She had the cutest little bottom, so I couldn't help but touch and stroke her, and then I let my fingers touch me and use her juice to penetrate her arse with one, two and then three fingers. It was amazing! Next time we used a dildo in her arse, and it was really hard not to come almost straight away!

Toys are an option for some interesting sensations.
