Sally and richard

Id been with rachel for about 6 months and her best friend was called sally ...we had been up to her house a couple of times to see her and her fella richard ...she was very slim good looking and was a personal fitness instructor...richard was a confident guy who ran his own business. They had a nice big house ...and had decided to buy a hot tub and we were invited for its first night . ..sally jokingly said bring your trunks to me ...i must admit i fancied sally and richard intrigued me so i was looking forward to seeing them up close in swimwear...a few weeks later and on the day of the hot tub night ..rachel told me to take my trunks rather than shorts as that was what richard was wearing...i jokingly said you will be looking forward to seeing him ...she just embarresdly blushed....when we got there richard was in the hot tub and sally had a dressing gown on ...they had a big shower room and told us to change in there..i was quite horny as i got changed and rachel was ribbing me saying that i would be excited to see sally as i had admitted i thought she was fit....tbc
