Licking My Step-Brother's Asshole

This might seem wild, but I'm totally panicking and unsure how to handle it. My lover, whom I deeply adore and hate the thought of losing, has been begging me to tongue his anus lately. I've never explored anything like that before, and it's making me incredibly anxious.

I can't confide in my friends because I don't want them judging me as weird or spreading rumors around campus—you know how chatty 18-year-old women can be. The only one I trust with this is my step-sibling, who's always been my closest confidant; he was even the first to hear about my first time having sex. My step-sibling noticed I was on edge, especially when I checked that our parents were downstairs engrossed in their show—he sensed something was off.

After beating around the bush for a bit, I finally spilled it: My partner wants me to rim his backside. Even my step-sibling, who knows all my secrets, was stunned for a moment. But then it got even more intense.

I found myself asking if his girlfriend Shelly has ever tongued his rear entrance. He was hesitant at first, but seeing how earnest I was, he admitted that he's allowed her to lick his anus. That's when I crossed a line I never imagined: I asked my step-sibling if I could practice on him and explore licking his butthole.

See how he actually parts his thighs, revealing his naked rear to me, inviting my tongue to delve into the folds of his exposed anus. Tasting my step-sibling's ass has me dripping wet like never before, and I could see his erection swelling right before my eyes. Soon, I'm stroking his hardening shaft while rimming him deeply.

Then, he turns the tables, flipping me over to return the favor by licking my own tight hole. We were both so aroused at that point, we ignored the fact that our parents were just downstairs. With my legs wide open for him, he plunged his stiff cock into my drenched, eager pussy.

It felt thicker and more intense than anything my boyfriend has ever given me—it pulsed with every thrust inside me. Finally, I sealed the deal by tonguing his anus again while jerking his throbbing dick until he released everything onto my hand and his stomach. Even if I do end up rimming my boyfriend, I doubt it'll ever match the thrill of my first adventure with my step-sibling.
