Yourself, pushing inside of a tight asshole

Pumping your cock faster, you bring yourself right to the edge of orgasm before backing off. Staying away from your own asshole, you squeeze your member and visualise pushing into a tight asshole with it. You begin to rub harder, imagining the feeling of struggling to work it into such a tight hole. As your pumping becomes furious, you reach your other hand to tweak your nipple, and the simultaneous stimulation throws you over the edge into a powerful orgasm. You feel your cum splatter across your hand and belly, but unable to bring yourself to move, you stay in the same position for a few moments, relishing the waves of pleasure. Then, hungry for more orgasms, you pull your thumb out once again, and throw your hand under your bed in search of your shoebox of trusty sex toys.

But they're gone! You grope blindly for a while, then even turn the lights on and stick your head under the bed to look, but they're nowhere to be seen. Groaning, you flop backwards onto the bed; looks like there's no other option for you today....
