I would have thought it all a dream had Kate not been lying there next to me in the bed naked and facing me, still asleep. I stared transfixed at the ...ight of her plump round breasts moving up and down with her breathing. After a minute though, I couldnt take just watching anymore. Quietly and subtly as to not wake her, I leaned in and started suckling on her nipple, gently kissing and drawing circles around it with my tongue. Kate let out a little sigh, but showed no signs of waking. I kept. Justin stared at her speechless as she said, ‘I guess that b*****rs and s****rs aren’t supposed to do it with each other, but you’re so cute and I am so horny. As long as you’re careful not to get me pregnant… I don’t see any harm.’ With that she straddled her b*****r and guided his stiff cock into her moist slit. As she looked down at him, smiling, she began her familiar fucking motion, tightening the muscles of her pussy around his cock as she moved up and down his shaft. Justin pumped in. It was a black one with red lace on the front panels. It made my breasts look larger, and I wanted that for today. I then put on a spandex thong pair of panties and slid some nude nylons up my legs and attached them to the garters on the corset. I sat at my vanity and did my make-up, going for the professional woman look as best I could. I used just a hint of eye shadow and went with the pink lipstick again for the day. I stayed with the same hairstyle as Ben and his wife had seen me with last. It wasn't until I took it from her and turned it around, that Irealized what I was holding. "Katie, this is a dress." Uh huh." She pulled a tight black tank top down over her breasts andglanced at herself in the mirror. "You're too tall for anything of mineand too skinny for most of mom's stuff. That dress is from the when-I-lose-some-weight end of mom's closet. I think you can pull it off." Shegave her own bare ass a slap. "I need to see what I've got that'll getover these hips." She slipped.
