On my return from a business trip, I met with Sheryl to discuss the possibility. I suggested she travel with me on my next trip, to meet the client. S...e consented, I contacted the client, and arrangements were made.As we drove the 175 miles to the meeting (going in the night before), we did our usual bantering and playful flirtations. Nothing was ever suspected to come of it - we were just friends and business associates. That was to change, that night. We checked in to the hotel, got settled. While she was standing I pulled off her bikini bottoms revealing her trimmed pussy to me for the first time.My cock was almost touching her pussy lips already as she begin to sink her love hole down onto my long, hard shaft. "Mmmmmmm fuck!" I groaned as I felt my sister’s pussy glide down onto my hard cock for the first time, stretching her open the deeper she went. "Oh god! You're so big brother!" she almost screamed as she eased up before pushing down a little further each time. My cock was. I handle all the new hire paperwork and one day I needed a new guy in the warehouse to fill a couple of forms out. I walked out to the warehouse and tracked down the warehouse manager. I was wearing pretty flowery dress since it was springtime. It showed off my legs and boobs. I found him and he smiled and said I always make his day. I told him I needed to find this new guy who I had not met. He yelled back to the loading dock calling out the guys name which was John. From a group of guys I saw. ”My hand went faster on my cock. Hearing Ally's orgasm was quite erotic even with her not being next to me. I was getting even closer. “Ally, that was so fucking sexy. I need you here and now.”“Not yet, baby. Stroke that cock faster. I want to see your load of cum shoot from your cock.” Her right hand was rubbing her pussy, then she reached around with her left hand and started to finger her cute bum as well. Oh, what a sight that was! I swear, it almost sounded like a purr coming from her.
