My stepdaughter is driving me crazy (Part 4)

Katia keeps flying interstate for business. Frequently. Just a week later on Thursday I’m again alone at home with Nadine. Having her sit on my lap just wearing her bikini, near nude was amazing. I can’t stop thinking about it. I’m so aroused by the thought of spending time with Nadine that I decided not to wear my undies today. Just my loose trackpants, the thinnest I could find. It makes me feel a bit guilty to enable all this but my sexual excitement is soon pushing away my doubts. I’m sitting on my couch as usual, streaming the new series on TV. I can’t wait for Nadine to come down the stairs. Where is she? I can’t believe I’m so horny! Finally there she is. I’m hearing her steps coming down the stairs. But it sounds different. I’m looking over to her and she isn’t barefoot as usual. She’s wearing sandals. I haven’t seen those before. Open toes with an ankle-strap at the back. She’s wearing her nightdress as usual. “Hey Frank.” “Hey Nadine.” “Can I join you again on the couch for a bit?” “Sure darling.” She’s standing in front of the couch, next to me. Close to me. She’s turning around, backside toward me and bending down to undo her sandals. Right there, less than an arm’s length away! Her nightdress slips up. No panties! Her butt cheeks are parting as she’s bending down revealing her pussy. So close to me, I can barely stop myself from touching her with my fingers. I’d love to lick her! Her asshole, hairless and beautiful as always. I’d love to play with it! She’s taking her time undoing both sandals. My dick is getting hard, starting to throb. It’s good that the sofa blanket is covering my lap. I love her so much! How much effort and thought she’s putting into creating all this sexual tension between us. A goddess of seduction. I’m feeling so grateful for this experience! If she only wasn’t my stepdaughter. Or does that make it even more exciting?
