I tell you what, you get your tits out and we will see what we can do”Ha-ha I thought, that would teach her. No way would she agree and this would t...each her a lesson with for threatening to tell tales to my wife.“OK” she said, “But come into the lounge”This surprised me and it wasn’t what I had expected her to say.“Are you sure?” I asked.“Oh yes” she said, “but only topless. I am not showing you anything else” And with that she turned and walked into her lounge and sat in an armchair facing me. I started to sit down, when she Tandra told me I had missed her legs.I placed some more of the lotion in my cupped hand and started to play it to the back of her shapely legs, starting below the knee.“My butt too,” Tandra added, spreading her legs to tease me.I was hesitant to go there, but Tandra simply said, “We’re adults. Don’t be like a teenager.”So, I liberally applied the tanning lotion to Tandra’s upper legs, slipping my fingers dangerously close to the edges of her bikini bottoms. I. You wanna play with my cock while I finger that pretty little pussy?" Amanda slid her hand down to his cock and grabbed it and started stroking up and down slowly. "What if mom comes in?" she asked. "Don't worry we will hear the door and she always yells for me to get her slippers before she comes out of there anyway" he said. "MMMMM Good because I don't want to stop" Amanda said. She started having a big orgasm and he lifts his mouth up from her tits and starts kissing her to quiet her down. She walked over to the bed and sat down on the foot. Her legs and bare feet played with the covers.“That’s was some joke they played last night huh?”, she said nervously.“Yeah, that Jeff. He is a big jerk. I’ll get him for that. We should come up with a plan.” I said. I couldn’t help but notice my sister’s body. I know it sounds a little sick coming from her brother and all, but objectively she was hot. Maybe even hotter than Kelly. She had shoulder length, brown hair that she always kept tied.
