Fingering my stepmom’s pussy ended up in morning sex

It was morning time. My hot stepmom was still sleeping. Mom was lying on her side. The bedsheet partially unfolded her body. Due to this her ass was left naked. Although she was wearing a bikini. I secretly went near her and removed the bikini strip from her asscheeks, and started fingering her pussy. My mom felt that it was her husband who was fingering her pussy. But after some time, when she turned, she realized it was me. But by now, she was in the mood for sex. So she let me put my dick in her pussy. Then, we both enjoyed morning sex.
