Young stepsister seeking intimacy alone

This young girl is very shy but excited about having sex after school today when mom leaves work late again tonight. I’ve been waiting patiently ever since we moved into new apartment where parents forced us live together. We got separated during break time so now here comes my beautiful step-sis who came over home already. She looks around nervously before finally approaching me confidently enough asking “Can u help me?” Me feeling guilty confessing what happened between our families past. Then proceeded helping out by gently pushing fingers inside slowly increasing speed until reaching climax ourselves sharing each others sweat mixed love juices right there on kitchen countertop. Afterwards both tired yet happy knowing good things await tomorrow.
