.and then I lifted my head, looked into her eyes and kissed her softly, almost brotherly, on the lips. "Are you sure?" I asked.Lynn stared into my eye...."We're going to make love, aren't we?" she asked in a small, scared voice."If we keep this up, we are. But if you want to, I'll stop right now. I'd be full of shit if I said I never thought about doing this with you. I've been attracted to you for years. But..." I drifted off."Todd is your best friend," Lynn said softly. "And he's my boyfriend.". I could feel his hardness under my flat belly. He was enjoying the show. I wanted him to slap or at least touch my horny pussy. Now his hand moved up my back and swooped my bra and shirt off over my head in one movement. With the exception of my panties I was virtually naked lying across my brother’s lap. He rubbed my ass some more. My pussy lips sticking out from the sides of my panties. I was beginning not to care. I stuck my ass in the air in anticipation of his slap. My clit getting hard. Natasha came out wearing only a nice sweatshirt, looking sexy as hell as it showed off part of her shapely legs and was just long enough to make me wonder what she had on underneath. After the movie, we watched the news, the weatherman gleefully predicting another five or six inches of snow overnight. She was touching me all over, while drinking and cuddling together, further exploring the boundaries, suddenly the TV went blank, the snow had apparently cut the reception.And then I tuned the. This was when he stopped and, as I protested in frustration, he helped me up and back on the bed.I was in the same position as before, but not tied this time. I hissed a bit at the contact of my sore ass with the bed. The wet sheet beneath me began to alleviate that and it started feeling good. I bunched the pillows behind my back to see what he was going to do.As I was squirming, Mike stood between my legs again and slapped my pussy a few times. I yelped with the slight sting of each wet smack.
