Kenna James is thrilled to be going to prom with her younger step-sister Tara Morgan tonight. Now that the day has finally arrived, both girls are bouncing on the bed and yelling with joy! Tara is incredibly appreciative that her step-sister, or bigger sister, invited her to join her for this unique adventure. They assist one another in getting ready and tell one other how adorable they look. When they're all set, they call their partners, but none of them answers. They got up and stood! Tara is devastated and angry that these losers left them, but Kenna reassures her that they don't need guys to enjoy themselves at the prom. Knowing that their partners are no longer in the picture—that is, that they both wanted to get laid—Kenna and Tara discuss what kind of fun they could have after prom. They can enjoy themselves on their own, Kenna responds. Tara is at a loss for words; even though they are step sisters, she still thinks of her as a biological sister. Given that Tara is a virgin, Kenna believes that there is nothing more attractive than having sex with her sister. Tara has never had a sexual relationship and is therefore unable to enjoy the company of another person; fortunately, her older sister is there to support her throughout. Tara is led by Kenna into their first tender kiss as they passionately make out on the bed. Slowly pulling her dress off, Kenna makes sure Tara is staring at her bare chest the entire time. Tara lets her sister kiss her nipples by taking off the top portion of her clothing since she feels at ease with her touch. Tara prevents Kenna from continuing, no matter how nice it feels for her to carefully ease her way down her sister's body. Breaking the silence, Kenna tells her to have faith in her older As Tara puts herself under her sister's clit, she makes her cum in her mouth by sucking and kissing her labia. She takes off Tara's clothes, gets her on all fours, spreads her ass cheeks, and sticks her tongue inside Tara's ass while teaching her a new skill. Tara groans and gives her sister a strong rubdown, expressing gratitude for the pleasure. Knowing that she made her older sister proud makes Tara very happy.
