After several weeks of ducking the group, Leonard finally accepted a get together with Sheldon and Amy.
Penny and Amy came into the apartment as Sheldon was setting up a board game. Both Penny and Amy were protesting and Penny put in her two cents, "Listen every time we get together we do what you two want to do. Why can't we do something Amy and I like doing?"
Leonard stared at her, he thought she usually got her way when it was just the two of them, but he didn't press it. He turned to Sheldon, "I think we should do what the girls want to do."
Sheldon rolled his eyes, "Okay Penny you can be green."
He handed her the token, but she gave it back to him, "No Sheldon we want to do something outside the apartment."
Leonard had an idea, "How about we go clothes shopping? Sheldon and I will sit there and wait while you two try on clothes?"
Amy looked to Penny and they both agreed.
Sheldon and Leonard sat in the waiting area while Penny and Amy tried on an assortment of clothes and Penny peeked over the top of the changing stall, "So tell me Amy, is it true, you always do what I want to do?"
Amy chuckled, "Well yeah, but I made myself a promise, if I ever got a female friend, I would always do what she wanted to do."
"Ah Amy, come on, you name it and we'll do it."
Amy's eyes lit up and taking Penny's hand, she led her back into the stall and locked the door, "Okay Penny turn around and face the wall."
Penny giggled, "What? Why?"
"Penny you promised!" She waited until Penny faced the wall. She came up behind Penny and reaching up, she lowered the zipper on the back of the slinky dress she was trying on. She slipped it from her shoulders and tugging at it, it drifted to her ankles. "Okay Penny, now lean over and grip the bench."
Penny giggled, "Are you serious?" She did as she was instructed and she felt Amy's hands on her tiny thong. She felt it sliding down her thighs and suddenly she felt a warm breath on her pussy from behind.
Amy removed her glasses and grabbing hold of Penny's hips; she pulled her back and immediately penetrated her pussy with her stiffened tongue. She ran her hands around and pulled her back to her active mouth. She began licking and sucking on Penny's pussy and she drove a finger in her cunt and began finger-fucking her pussy.
Penny shivered and gripped the bench even harder. She straightened up and spun around. She flopped down hard on the bench and placed the heels of her feet on the bench and parted her legs. She patted her pussy, "Here you go Amy, I think you can get a better view and easier access to it this way."
Amy lowered her face and began lapping away like a rabid animal. She ran her hands up and down Penny's legs and slid upward and pulled roughly at her tiny bra. She began squeezing her tits as she licked at Penny's exposed clit. She felt Penny's thighs tighten around her head and she let out a loud grunt and began spilling her cunt batter all over Amy's lips. She sat back and licked her lips. "Mmmm, I've always wanted to do that. You usually start any sexual activities and I just wanted to be the one who started it first for once." She reached down, handed Penny her panties and stepping over to the door, she turned and chuckled, "Oh I thought of something else I want to do, let's go and do some basket weaving."
While Sheldon and Leonard were waiting, they realized that they didn't have any cell service or internet connections. They began talking and the subject of giving in to each other came up.
Leonard made the case that he couldn't even live with his fiancΓ©e. "What do you expect is going to happen once we are married?"
It hit home to Sheldon and he finally gave in and for a trial period, Leonard could stay over at Penny's apartment one or two nights a week.
This revelation shocked Leonard and he knew this was something big for Sheldon, and when the ladies came out of the dressing room, Leonard told her about the compromise and she could have been knocked over with a feather.
Amy was jumping up and down with their next activity and when she told they guys, they both groaned out, but not wanting to upset the apple cart they agreed.
Sheldon as always was adept and made a Chinese warrior hat. Leonard and Penny tried their best, but failed miserably. They ended the evening and after dropping off Amy, Leonard finally gave in and accepted Penny's offer to spend the night.
She dressed exceptionally sexy; she wanted to lure him into fucking her. She hadn't gotten fucked since Christmas Eve and she was raring to go. She had a sexy blue and white nightgown on that accented her large, perky breasts.
They turned down the bed, Leonard dressed in t-shirt and boxers, "Well, roomie, it's only one night a week, but it's a start"
She leaned over, exposing her charms and went in for a kiss, "I know I'm really proud of Sheldon." She kissed him and her hand dropped under the sheets to grasp his cock.
He bit his lip and let out a gasp, "Yeah, I'm proud of him too, if you're gonna start something like that, what do you say we bring him into the room too. I wouldn't mind a threesome."
She removed her hand and sat back, "Okay, this is where I'm confused, you get all bent out of shape when I have a threesome at Amy's with Vijay and Raj, but here it's okay for Sheldon to join the two of us? I don't see the difference."
He removed his t-shirt and glasses, "There is a huge difference, first of all, I'm asking you if you would like him to join us. I'm not forcing it upon you, you have a choice. At Amy's all through dinner you were giving Vijay a hand job and playing footsies with Raj under the table; all along, trying your best to hide it from me. After that, you were on the sofa with them and started without any regards to me or my feelings, do you see the difference? To top it off, I heard from Raj that you gave Vijay a blow-job while Howard and I were at the university doing our experiment."
She nodded, "Okay, so if I'm hearing you correctly, it's okay for us to mess around, as long as we have the other's consent?"
He nodded and only if both of us are willing to do it without being coerced or pressured into doing it, and especially not behind the other one's back."
She nodded, "Okay, I understand and I will do everything in my power to follow those guidelines."
He chuckled, 'They are not guidelines, they are the rules and if you can't follow them, then I don't see a future for the two of us."
She gave him a weak smile, leaned in and kissed him again. Her hand snuck back under the sheets and fisted his stiff cock, "Mmmm, I can see my thick buddy love making rules and making his woman obey them."
Sheldon yelled out from the living room, "Can you keep it down. Some of us are trying to sleep out here!"
Penny yelled back at him, "We were going over the rules for coitus, would you like to come in here and join..."
He jumped onto the bed, already tearing off his pajamas.
Penny giggled, "...us?" She threw back the covers and immediately wrapped her lips around Leonard's stiff cock, "Mmmmm, I've missed this big boy!" She felt something hard and wet along her cheek and looking up; she was staring at Sheldon's cock. He was fisting it and nudging it towards Penny's cheek. It was already leaking a droplet of pre-cum."
She pulled off of Leonard's cock and looked up to him, "So, is this okay?"
