The Endowment Club Study

Molly fed me a spoonful of gelato and said, "Alex, maybe you don't have to go so far away to college. We are going to need help with the study."

The other two smirked at me, "Yes, it's like you said, the criteria for PSI must be worked out."

An evil thought came into my mind. "What about Melanie? Isn't she pretty deprived? Why don't you give her a call and say she should put up the closed sign and come to the lake for an urgent conference. Tell her you need help with PSI, but don't tell her what it stands for."

They put the bowls down and sat on me again. "Three agreeable bodies is not enough? You have to have a fourth? This is ridiculous."

I scissored Molly and undid her nothing bra. "Don't kid me. She is hotter than a pistol and will be all over you."

Heads were drooping. "Hmmm. You better do it, Molly. We need to get her excited about the study."

I mumbled 'excited' to myself and fell asleep.

We were still having breakfast when Melanie appeared. "Wow! This is fantastic." She grabbed my coffee cup and smiled over the rim. "He is behaving?"

Heads shook, watching her start to undress, wondering what next.

She already had her suit on, what there was of it. "An early swim is permitted? After, you have to explain PSI. Is that like PMS?" She was in the water in a flash, leaving us laughing.

I pulled Maya into my lap, hands pinching. "I told you she was hot. Take off your shirts and get in there. I want to see some action!"

Molly blocked my view, straddling me and pushing her chest forward. "What if we go in the bedroom and I start screaming your cock is too big? We can give them a show. I can tell her I am having PSI."

She wasn't finished babbling when I had her in my arms, walking into the house. We wrestled on the bed, warming up.

"Put your hands on the headrail. It's time for the rough stuff."

Surprisingly, she did it, looking back over her shoulder and shaking her rear at me. Her furry bottom with the pink center was like a magnet. I let out a giant roar, taking a chance that she was nice and wet, and plunged straight in. The scream was long and warbling. I gave in to all my alpha instincts and used the big cock to ream fully inside, my balls firmly against her ass.

"No, no, you can't," she howled. I reached for the bouncing tits and massaged vigorously. We were still rocking and howling and laughing when three wet bodies piled into the room.

"Oh. My. God. Look at that." Melanie's voice was gasping from the swim and the dash inside.

Molly yowled again, her body seizing, and I let loose with my own climax, shouting "Yes!"

The study director lay on her back, smiling at Melanie and saying, "PSI, Melanie, PSI."

The varsity swimmer doubling as summer office assistant dropped her wet suit and advanced on Molly.

"You are not allowed to tease me. You have the most delicious pussy I have ever seen. It has to be tasted."

A few good licks at the squirming pelvis and she was curling into my arms. "Tell me."

I whispered in her ear. "Perceived successful intercourse. It goes with the revised study."

My hand was gathered to her breast as the head turned for a kiss. "They are sluts, all three of them, aren't they?"

The interns were working Molly over, continuing what Melanie started. Melanie twitched and wiggled and arranged herself on top. "I am late to this party, but very needy. I can almost guarantee PSI riding on this big thing."

My fingers danced up and down her spine as my tongue reached for a boob tip. "You are going to give a public demonstration?"

"I love public sex. My ex-boyfriend and I used to get it on in front of my married sister and her husband. He took her on the floor right next to us, wailing no and coming at the same time."

The compact swimmer's body was in constant motion as she talked, handling my cock and sliding herself slowly down. "God, you ARE big. The study girls are going to scream their fool heads off."

She looked around to watch the trio of other tangled bodies. "That Molly. If she wasn't the director of a sex study, she would be a nympho in some show."

Melanie leaned forward and grabbed my long hair, pulling backwards until I was crouched over her. "Now, make me scream."

She believed in performance sex and I loved it. She had a lovely trill in her voice as we worked up to her first orgasm. "Yes, yes, yes," she shouted at the top of her lungs.

I was in total bliss, lying in the destroyed bed with four orgasmic women.

"Ladies, I'd hate to spoil any fun, but you do have to start writing some of this down. Are you going to use a one to ten scale? Is the orgasm going to be rated separately from the overall experience? Some women enjoy sex without climaxing. At least they say they do."

Melanie stood by the side of the bed, grinning and dripping. "Am I a study subject now?" Her tight ass disappeared into the bathroom.

Maya was on me, asking if there was something left for her.

"There is a lot of acting out going on. What kind of wild public sex do you want?"

"Yoga sex. No shouting. No violence. I will do a headstand and you will copulate with me, silently and beautifully. If you perform well, I will come, and so will you."

"Ok, I am willing to try. But first we have to apply body oil."

I spread the oil as she worked through several poses, stretching. Her sex was recently waxed and looked like art. I should be bare myself for this, I thought.

Her quiet seductive voice got us positioned and my very hard cock slid home. "Don't move now. I will squeeze and you will give tiny thrusts with that enormous cock which is filling me like no one else before."

Her arms were cradling her head on a towel, with my legs behind her torso. At her hips, each leg thrust horizontally outwards, revealing the crease of her sex to everyone. My front was to her buttocks, the big cock entering her from the rear position. My hands were collected on the back of my head, fingers intertwined and elbows out. I had fixed us tightly together, before raising my hands. Her clenching vaginal muscles were maintaining the pose.

We could only hold the position for five minutes, until she fell to floor, noisily pulling me down and saying, "Finish me!"

Her scream as she came was very loud. So much for silent yoga sex, I thought.

Maya kissed me hard as her body thrust upwards, keeping me hard. I asked, "It didn't work, did it?"

She laughed merrily. "I keep hoping, because the book says it works. But none of my yoga friends nor I have ever come in that position!"

Sonya's toe prodded Maya, "Yoga tramp, let me have him."

Her hand gripped my slimy appendage and walked us outside. "I want you in the sunshine and outdoors. Pretend you found a forest elf and chased her to this deck and trapped her against the table."

This was very fine. She was still talking as my well used purple helmet found the wet place he was looking for and eased forward. "Ohhh. Yes."

We started slow, but the sight of all the coupling inside had her worked up. I whispered, "What do beautiful, sexy elves say when the evil cock spears them?"

"They say, 'Oh master of the forest, make me yours!' " She giggled and I drove harder. The tight cunt was having fun, and so was I.

"Sonya, you are a hot thing and a good fuck. I'm going to give this a ten in my little book!"

"Oh master, harder, I am only at eight!" I swore to myself that putdowns from assistant study directors were not allowed, and finished her with everything I had.

Washing off in the lake, her hands were on my shoulders as we watched the others join for another swim. "What if you hook up with Melanie? She's hot and she's smart and she is a jock like you are."

"I'm supposed to give up the rest of you?"

I could feel her stiff nipples rubbing on my back and didn't want to think about giving them up.

"We'll make a deal. She shares you, and we share her."

I turned around and kissed her, sinking us. We came back up and I said, "I don't think your behavior is permitted by the intern handbook."

"You worry about keeping your cock ready, and Maya and I will worry about the intern handbook." She took a bite of my shoulder muscle.

After swimming, Melanie stretched out on a lounger and wanted sunscreen applied. I sat next to her on the deck, ministering to the glorious body very carefully.

"They suggested I should hook up with you."

Her eyes were closed but she was smiling. "After that rude behavior inside, why would I want anything to do with you? That wasn't even worth a five."

I leaned forward, capturing an oily nipple, caressing it with my tongue, and biting down.

"Oww. That's nasty." The eyes were still closed, but her fingers were tugging on stray locks of my wet hair. "I'm not sure I can keep up with a guy who is getting so much good sex."

Looking around to make sure we weren't being overheard, I said, "They needed help with their sex study. I provided help. Do you think I could be allowed to be your boyfriend and taught to behave?"

I took her hand and kissed and licked the long fingers. She rolled off the lounger on top of me.

"Alex, it is very nice here in the sun on your deck and I am going to cry."

"That's not allowed. I only asked if I could be your well behaved boyfriend."

I smeared more sunscreen around on her back as she sniffled and licked my ear. "I have an instant crush on you."

"Funny, I feel the same way about you."

"I shouldn't have teased. That was really good sex in there. At least a ten." She flipped her hips at me and giggled. I was getting hard.

"You are terribly late to the party. I guess there has to be more."

"What if they come after you? What do I do?"

"Well, I'm willing to be on a short leash, but if you were feeling generous, you could think of sharing once in a while."

She sat up and impaled herself on my shaft. "Sharing this?"

I stared at her, puckering my lips. She leaned in for a kiss and let out a long, low laugh. "You devil. You total devil. You make me feel so good. I must be a slut like them. I am sitting here, squeezing you, and seeing a movie of the great fucking in the bedroom."

I stood and walked us to the kitchen. Most of her weight was on the big shaft rammed upwards in the wet socket she offered.

I raised the body and planted it on the counter. "She says I can be her boyfriend. But no sharing without permission!"

Naked Melanie was surrounded. Voices were pleading and offering favors. I went to get dressed.
