here's the current play by play situation...***SPOILERS, INVOLVES SEXUALCONTENT DEPICTING SEXUAL BEHAVIOR*** hope I didn't ruin it for you!!!
I was in Pittsburgh all weekend and got back to Philly around 5:30ish tonight. I go straight to my buddies house on a whim to see if people where hanging at the pool. There's a decent crowd and i'm feeling very comfortable so I'm cracking jokes...maybe 10 minutes in and i'm about 3 "OK" jokes and 1 banger that has the whole group rolling.  I can tell she's listening because she's cracking smiles just like everyone else. I go on a little longer just vibing and as we're all having a blast laughing and busting each others balls and tits. Suddenly I start to get strong bang me vibes from this petite blonde hanging out with the group, but I had not met before. She is fresh out of the pool siting in a one piece bathing suit that left little to the imagination...i wasn't upset. Matter of fact I could have sworn her little squished penis pleaser was actually winking at me through her suit. Almost as if her pussy new it needed to breath and I could be a lifeline.
I toss her a smile to let her know I'm noticing. I know she's listening, she's reacting actually how our entire group was to each comment...just a little more secluded or shy.  So we're all sharing stories and she's silent....then all a sudden one of those inevitable lulls in convo springs up and we're shifting around again, but she stays put. So feeling awkward I ask her if she would like a fresh drink, she says....cool. Then of course I  get distracted by friends and now she's been waiting, not cool. Luck has it I come back and find her chilling alone, now standing by the firepit...way to close and scorching.  I come up behind her slowly and still mange to "surprise" because rather than say anything I began rubbing the edge of the ice cold drink on the nape of her neck. She acts startled at first but I could tell and in an instant her eyes changed and rolled slightly back with an almost silent sigh, more gasp. Without another thought i continued the ice cold cup slowly around her neck, while i begin lightly kissing her neck. She starts to arch her back a bit and I can start to feel the heat coming from her hot box as she's trying harder and harder  working her ass hard back against my cock....I'm growing fast! Now i'm showing through my pants and starting to throb and of course at that moment the rest of the groups starts to wander back out.  Just before they're in good enough range to see she quickly reaches behind and takes my cock (still in my pants) and gives it nothing more than a stroking pet  from base to tip with this little run around the rim of my head with her finger following the outline in my pants....then she turns around and now wants to use both hand and make me cum right then....just want I would want, cuming over a fire pit like Evil Knievel poised in the direction of the returning group heading straight toward us...i have to immediacy pull away. But now it's obvious it on so I  back off completely  leaving her shooting me a look...something tells me she was ready.😵
About 45 later I'm heading inside to use the bathroom and not 10 sec after she walks straight in on me and goes right to the sink starting small talk while washing her hands, he skirt already up past her waist and ass primed....I'm immediately hard, cock in hand. I get close behind her and push her head and back down soo i can get that ass right where I want it. Still face down as up I say to her "so, you think you can just claim any cock you want...and tonight you want this (as i give it a little more friction and a classic guy cock slap move)"? I didn't expect an actual response, but then just one word was whispered as she moaned...."yessss". 
Almost gushed on the spot, instead my left arm immediately grabbed her entire torso, arms and all, from behind and squeezes us both together so she could feel my cock nest in her ass just pressing her as apart as if it was custom fitted to her cheeks. Holding her firmly i push into her a little more, wedging her firmly between me and the sink and then again with my other free hand I grab her hair at the base of her neck, closer to her head for control, not pain. I pull her head fully back so she looking up at me and she smiles again...adorable with this hint of something else...erotic but dangerous. I tug her head back some more and make out just long enough for her to want to keep going. grip on her hair, tug back a little harder so she knew what was coming. 
My cock is throbbing and plump like somone had used it as a balloon animal but instead of a dog it was a full on blunt sword and I was full on her against the sink holding strong onto her silky blonde scruff of hair from behind and now she desperately twerking and werking my cock any which way just to get something out of me....but I'm on top just teasing. I let her squirm for about a minute before I let her suck my fingers and let her guide them them down her thigh and around her perfect pussy mound.... preparing for more. Fast forward a tick and her clit is bulging the same as my cock and together I've worked two of my fingers right where i could tell she's wanted them before and I start butterflying my fingers back and forth, rhythmically dancing  on her g-spot….it was easy to find, so I was hitting it faster that I think she expected. I was like Lionel Richie dancing on the ceiling!  As I'm about to make her cum on the bathroom sink, my dick commanding to spread her open, she starts dripping....it's time. Once again I grab her to have her facing me and softly I tilt her face to look at me, softly kiss her on her bare neck under her ears  pull my cock off and fingers out to cut her orgasm short (edged to perfection)...her eyes narrow with confusion and I simply leaned in close and whisper...patience. 
The I slapped her ass hard and just walked out as if nothing happened. 30 min goes by, she leaves because her daughter could stay with her friend….party dwindles, I leave and now I'm just getting home and like
