Fucking your girlfriend during her period

He knew his girlfriend was on her period, but he saw her lying there with her beautiful ass in a thong and felt an uncontrollable erection. like so many other mornings, he put his dick in her while she slept to stretch her, and even though she smeared blood on his dick with the rule, he continued with his business, and she didn't want him to stop either, so she came there and filled him with all the fluids.
