I was in 7th heaven. It truly was like riding a bicycle. It cums back to you in an instant. My cock felt so very much "at home" in Della's pussy. It felt so very natural, even having Suzie stepping into the room while Della and I rekindled the past.
I stopped thrusting into Della, just pressing my hardness against her as hard as I could, and holding steady while she gyrated her ass back against me. The walls of her pussy were massaging me, milking me, urging me onward. The guttural sounds coming from Della told me that she was enjoying this just as much as I was, and that was important to me. She always seemed to be taking care of other people's needs and desires, this was for her (o.k., I confess, it was somewhat self-serving for me also).
My concentration on what was happening below my waist was interrupted by Suzie's voice. She called back, over her shoulder to the store, "Debbie, Barbie, just keep browsing if you'd like, I've got some business to take care of". With that she stepped the rest of the way into the dressing room and closed the door behind herself. Oh my god, there were still people in the store! My fears were confirmed by two very distinct female voices replying that they were fine, and for Suzie to "take her time".
Suzie began walking over to the far corner of the dressing room. As she walked past me she put her hand on my shoulder, as if we were meeting in some place even more public than this store, looked me in the eyes as I looked up and apologized for not getting a chance to properly greet me when I walked into the store, but she had been busy. She then leaned forward and offered up her mouth for a very erotic, sensual, fully interactive kiss. Our tongues were invading each other's mouths, dueling with each other. I could fell Della's movements not only because of the fact my cock was buried deeply within her incredible pussy, but Suzie was leaning forward, keeping her balance by having her hand resting on the small of Della's back, so the movements were transferred also through Suzie.
Breaking the kiss Suzie continued to the corner of the room, sitting down in an overstuffed chair that was situated there. When she sat down the hem of her mini-dress slid up her thighs until it was obvious she was wearing thigh-high hose with garters. It was also obvious that the material of her thong was soaking wet and pulled tight in between her pussy lips. This had to be obvious to Della also, since where Suzie had sat down at was about four feet directly in front of Della's face. Della confirmed the view with "oh my god, this is so great. I've waited so long for this, and with my two friends. Della then began fucking back against me with even more energy, and the events that were unfolding caused me to press back against her with increased intensity. I couldn't get deep enough inside of her hot pussy. I wanted to just follow my cock right up inside of her, as if that were possible.
