I was at my girlfriend's house for a family birthday/BBQ sort of thing. At some point things began to thin out and people left, and finally my girlfriend's mom and aunt went out shopping leaving my girlfriend, her female cousin, and my male self alone at the house. We were hanging out in the pool and spa, switching back and forth in the autumn coolness as neither was really comfortable for the time of year.
At some point, her cousin got up to go fetch some wine coolers, and while she was gone, my girlfriend turned to me and grabbed my crotch firmly, stroking a little as she asked, "Sandra's got nice little tits, huh?"
"Not as nice as yours," I replied honestly, if politically.
"I played with them before," she said, upping the ante.
"Really?"
"Yeah but she stopped it because she said she didn't want to be a lesbian."
"So I could still play with them then…," I joked.
"Mhmm do you want t-," she was cut off by her cousin's return, but I thought I knew where she was headed and nodded "yes".
"I fingered her pussy," she whispered in my ear at the next opportunity.
