I confess that my wife’s stepsister has been sharing her body with me since this summer. She’s a college tennis player and was back home because of the pandemic. We have dinner at her parents’ house once a week and while she was home she would walk around in her workout gear or those big sweatshirts with no pants on underneath. I saw and stared at her ass cheeks all the time. Couldn’t *not* look. She’d wear those black yoga pants with neon panties underneath and sometimes none that I could see at all. Even better when she would wear those spandex shorts meant to be worn under tennis skirts and shorts. Perfectly tight and toned.
On one of our last dinners before she went back to college she wore a white tank top with no bra. Skin tight, nipples poking through in the a/c. I couldn’t stop staring, and I know she knew. We cooked out and it started raining and it got wet before we could all get inside. You could see everything. It was obvious she tans without a top on. I couldn’t help but get hard.
My wife gave her shit for it in front of me. “Thanks for the show. Maybe you should change.” You could tell she was pissed.
She went upstairs and came back with a giant sweatshirt. I made an excuse to run up and check the score for my team in their bonus room and walked past her. “Maybe you should change that shirt, too.”
She smiled up at me. “Did you like my last one?” “I didn’t see anything wrong with it.” “Good,” she said.
That night I got home and had a Snap from her. “Hey.”
“Hey. You back to appropriate clothing now? I don’t think your sister liked that outfit lol.”
“*Step-sister.” She said. My cock got insta-hard.
“Oh, sorry. Would she approve of what you are wearing now?”
“You tell me...”
