Stepsister joins in as boyfriend enjoys anal sex with me

After indulging in some steamy oral sex with my boyfriend, I lay back and let him plunge his hard cock deep into my tight asshole. The intense pleasure sends shivers down my spine as he expertly stretches me. Unbeknownst to us, my stepsister sneaks in and decides to join the fun. She's always been curious about anal sex and now she gets to witness it up close. She eagerly takes over, her tongue exploring my wet pussy as my boyfriend continues to pound my ass. The sight of her licking my pussy while I get my ass fucked drives me wild. The room fills with moans and the sound of skin slapping against skin as we reach our climax. My boyfriend pulls out, his cum covering my ass while my stepsister licks every drop off my pussy. The sight of her sucking on his cock leaves me in a state of pure ecstasy.
