Study(closed for Midnightwalk)

John, hearing Lisa's moans, switches focus to a different set of readings, watching the spikes and valleys as the couple approaches Mike's orgasm.
 
Mike

Mike begins to concentrate to get off. His balls are full and ready to pop. Lisa's pussy is twitching and convulsing on his cock. She's so wet her pussy makes slurping sounds from time to time. Mike grunts and feels his balls rise. He can feel the monitor on the back of his sac. Mike grunts and then moans and says...oh fuck. Lisa squeals as his first shot scalds her pussy walls. His balls suck up and he unleashes a huge load into his wife's pulsing pussy. He and Lisa moan and groan together as he stays balls deep and pumps he hot seed into her. Mike sees light flashes then he has a vision of hot little Tina laying under him accepting his load. When his eyes roll back down her looks over to her. Lisa's strong pussy muscles milk his cock as she spasms with him. They milk his cock and make his balls unload a few extra shots. Fuck he had been pent up. He finally quits cumming and kisses Lisa then crawls off of her. His softening cock flops over against his thigh as he lays beside his panting wife. Lisa's pussy is gaped open from the fucking and semen is flowing out of it. It runs right down her ass crack down to the sheets. Lisa and Mike lay together panting until Mike finally looks up and says..so was that alright?
 
John and Tina watched as Mike climaxed inside Lisa. Tina, wide-eyed, stared. John checked the readings, making sure the recorders got it all. He looked up at Mike's question. "Oh, it was very helpful." He smiled. "I assume it was good for you two?"

He walked over to one wall and picked up a milk crate, carrying over to the panting couple. "Sorry, seems a little impersonal, but I'm not sure what you might want to use." Inside the crate are towels, washcloths and baby wipes. His eyes travel over Lisa's body, those big breasts flattening slightly on her chest, before looking over to Mike. "So, what's your average refractory period?"
 
Lisa

Lisa likes how John is looking at her..laying there in her afterglow naked and wide open. Lisa giggles and says...refractory period?...kind of a big word there guy....the three of us laugh. Mike grabs a towel out of the basket and gets off the bed and towels off his cock and balls. Out of the corner of his eye he sees Tina watching him. Mike smiles o himself...yeah honey that's how a real man fucks a woman..not some little college age shit. Mike tosses his towel away. Lisa grabs a washcloth and reaches down and cleans up her pussy. She smiles...mike really outdid himself with this load. She fills up the cloth with his cum as she rubs it over her pussy. She raises herself up with her feet on the bed and runs the cloth down over her ass as she had been leaking. She tosses the washcloth back into the basket and grabs another...fuck did Mike cum! She finishes cleaning herself then asks...do you mean bounce back time?
 
John steps back as the couple cleans themselves up, watching and evaluating their older bodies. He nods. "Yes, bounce back, that's exactly it. How long does it generally take?"
 
Mike

Mike chuckles...well that all depends. He says...right now I have to say I am very turned on and it probably won't take long. He continues....if I was tired or anything it would probably be a no go. He's still,standing by the bed. His cock and balls hang loose and relaxed...fuck he loves that feeling...and he knows he is giving Tina a show. Mike says...at home sometimes we will even use a cock ring on the second..or even third go...it just keeps me harder after that first cum. Mike says...I did just cum really hard right now but if you want us to try another go we surely can. Mike smiles and pulls up his ball sac and says...I will need another monitor though...I must have tore it off when I toweled off.

Lisa

Lisa lays on the bed watching Mike raise up his ball sac. She looks past him to John. She smiles to herself as she sees the bulge in his khakis. There is also a wet spot of pre cum on them...nice. She looks over to Tina...poor little thing. She looks embarrassed and flustered...oh well.
 
"Oh, believe me, I'm not going to ask you to do anything, quite yet. We're still establishing a baseline here." John gestured toward Mike's genitals. "And I don't think we need monitors just now. That was fine for a first go. In fact, you can remove the rest, if you like. Up to you." He smiled.

"So, you would say the study is altering your sexual responses a bit? Please, be honest about anything, that's the whole point of the study. Learning about people over 50 and their sexual responses, dreams, desires, etc, etc."
 
Mike

Mike lets his balls drop and sits down onto the bed. He's a bit disappointed as he felt ready to go again. Lisa crawls up beside and sits beside him. John sits on a small chair in front of them. Mike says...I feel this was a fair to good example of out typical love making session. He continues...Lisa has always been a big time cummer..haven't you dear. Lisa smiles and kisses Mike on the cheek and says..it's all about loving your guy that's all. Mike smiles and says...and having the right woman..Lisa has always driven me crazy...I knew the first time we fucked she was my woman. Lisa rubs Mike's back and listens. Mike says...her pussy is just amazing...it's so small and tight...and she pulses and twitches every time she cums..it's just amazing...and she has very strong inner muscles too. Lisa blushes a bit. Mike goes on...to this day every time I enter her it takes my breath away. Mike finishes up...yeah I would say it was a good example of our typical fuck.
 
Lisa

Lisa is a bit taken aback by Mikes very graphic description of her pussy...oh well...all for a good cause we hope right? After Mike gives his view Lisa pipes in and says...I would agree what you just saw was a fair to average example too...I have been blessed by being able to orgasm so easily...and so often. Lisa smiles and says...but the credit goes to Mike..he's an amazing lover....he's so good with his tongue and it just seems his cock was just made for me. Lisa feels very good. It feels very comfortable and very sexy to be naked and discussing sex. Lisa says...as for being watched...well...we find that very sexy..at the nude resort we went to every night we screwed by the pool and hot tub and other couples were doing the same thing...that was hot. Lisa thinks a moment then says...I would have to say though I feel if we all got to know each other better the study would go much better...I think we could feel even more comfortable performing and be much more comfortable in our discussions with you.
 
John nods, listening to the couple, not bothering to write anything as the recorders are still running. He smiles at Mike's in-depth description and Lisa's candid follow-up.

"Very interesting," he allows. "I have two questions for you, off the top of my head. One, what would it take to make it an outstanding experience for you? And two, how would you like to get to know us better? That's an intriguing take on the study. Or are those two questions connected?" He smiled.

Meanwhile, Tina watched the exchange, a bit nervously.
 
Mike

Mike says...I think as we go we will all get more comfortable and the sessions will get better...I thought it was amazing today anyway...I had one of my biggest cums in a long time. He says....you are in charge here so just let us know what we need to do as well...we did sign on for this you know. Lisa says..I think getting to know each other is very important...we will feel more free to really let ourselves go...and be more frank in our discussions...how about you both coming to our house for dinner?...we can grill some steaks and just chat and get to know one another....any significant others are welcome as well....looking to you with her huge brown eyes.
 
John sighed, clearly hesitant. "On the one hand, it's standard practice to stay at a removal from one's subjects, so as to not taint the results. On the other, if it makes you more comfortable and more willing to be open...that can only be good for the study."

He glanced over at Tina. "We'll try dinner, see what happens. If it goes poorly, I hope you won't be offended if we hold our distance. Fair enough?"
 
Mike

Mike shakes your hand and says...fair enough. Lisa asks...is there a shower where we can really clean up?
 
John laughs, ignoring the fact that he's shaking hands with a naked man he just watched fuck his wife.

"Sure, if you're done. It's downstairs, third door on the left. Take your time, we're gonna collate our findings. You all were very helpful today."
 
Lisa

We just leave the room naked. You watch my big round ass wiggle. We get to the shower and take the monitors off of each other. The two on my inner thighs are soaked with semen so I just throw those away..the others we leave on the counter. We talk as we wash each other. We both agree it had been a fun interesting experience. Mikes cock gets hard as we talk and we both have a good laugh about John's question about refractory time. We dry off and go ack up the stairs to the room where we had performed...not having thought about taking our clothes along when we showered. We walk in to see John and Tina watching our session on a big monitor. We walk up beside them naked and watch...fuck we look hot. Mike clears his throat ans says...uh John...about that refractory time...looking down at his erection. The three of us burst out laughing...even Tina gets a little smirk .

"Yes, that's not bad bounce-back," John allows. "And if you're curious, the data looks very promising. We'll just have to run it through the proper filters and programs and we've got a great start. I appreciate you both being willing to participate."

He looked at the nude couple. "We'll let you get dressed in peace. On your way out, you can let us know when you'd like to return and when dinner is, if you still want to." He smiled. "Come on, Tina, let's let these good folks get dressed now." He led the blushing redhead from the room.
 
Mike

We get dressed and discuss dinner. As we walk out we give you our address and tell you the plan...steaks on the grill out by the pool. Lisa again tells you a significant other is welcome. Mike smiles to Tina and says...and if anyone is lucky enough to be your boyfriend he is welcome too. Lisa says...and as far as our next appointment...it's up to you....we loved this...it was so much fun!
 
"Very good, we will see you then."

As Mike and Lisa leave, John discusses the issue with Tina, formulating a game plan for the evening.

Later, there is a knock at Mike and Lisa's front door.
 
Lisa

Mike and I had been so excited about our session. We talked about it all the way home. We quickly changed clothes and got ready to grill some steaks we had stopped to pick up. Mike stocked the bar out by the pool and hot tub as I busied myself in the kitchen. I wondered if John would bring a wife or girlfriend..it was going to be an interesting evening for sure. Lisa hears someone at the door and goes to answer it. She stops and looks in the mirror in the living room. She smiles to herself....looking good hon. She had put on a white tank top with no bra and it was nearly see through. Her nipples were erect and the material stretched over her big aurolae...John will like that. She's also wearing shorts with the bottoms of her big ass cheeks showing. Lisa opens the door with a big smile...ready for anything the evening has to offer.
 
"Hello." John stood there, holding out a bottle of wine. He had changed into a pair of khakis and a short sleeved shirt. He smiled at Lisa, eyes dipping to her very ample chest. "I hope we're not early."

Behind him stood Tina, looking a bit uncomfortable. She was wearing the same silk blouse and short skirt she'd had on earlier. She gave a hesitant smile.

John saw Lisa's glance behind them. "Sorry, just us. My wife's out of town and Tina tells me she's between boyfriends. I hope that's all right."
 
Lisa

Lisa smiles...so he is married. She looks past John...Hi Tina...so glad you could make it...won't you come in? Lisa takes the bottle of wine and leads you through the house. She leads you into the den and it opens up onto the patio were Mike is starting the grill. Mike sees us and comes into the house. He shakes your hand then says to Tina...glad you could make it. Lisa opens the wine as Mike takes you outside showing you the pool and hot tub. Tina stays behind. Lisa says...so Tina...what do you think of the study so far?...hope it's what you had thought it would be.
 
Tina glances at John, looking around the house. "Oh, honestly, it was just a job. I'm a work study for Professor Miller. I wasn't sure what to expect. It's been a bit...embarrassing, to tell the truth. I didn't think I'd be watching people actually, you know...." She blushed, nipples poking through her silk blouse again as she stutters through her explanation. "How is it for you? I mean, doing things like that in front of people and on film. And with those monitors attached to you?"
 
Lisa

Lisa giggles and says...it's been fun..given us a chance to be a little naughty you know?
 
Tina smiles back. "That was naughty? That was just foreplay and intercourse. Didn't seem so naughty. Oh, well, the part where you were doing it in front of others, yes." She looked around the living room. "You have nice taste. This is really a nice house."


Following Mike outside, John looked around the patio and back yard. "Nice and secluded back here. I expect you two use this area a lot?" He smiled. "I'm sensing we haven't even seen the tip of the iceberg with you two, have we?"
