Once inside the bedroom, they shuted the door behind their back. She kicked off her sockless shoes and kept kissing him, pushing her tongue deep in his mouth while his erection was growing fast every second. He took her sweater off and helped her taking off both his shirts, throwing them on the floor. Then his tongue went to her ear and neck.

He passionately sucked on her skin, and she moaned, running her hands on his naked back. He unclipped her bra and threw it on the floor with the rest of their clothes, then she lied on the bed with her breasts exposed. He took his shoes off and climbed on the bed upon her.

He caressed her boobs, gently squeezing them as she gasped in pleasure, and he kissed them, sucking eagerly and nipping her nibbles. After a minute, his lips went down to her abdomen, while his hands were caressing her awesome hips.

She whimpered when he started kissing below her navel and near her forbidden spot. His tongue moved very slowly, trying to prolong both their pleasures as long as they could.

When Sheldon started to unbutton her jeans, she arched her back to make it easier for him. He took off both her jeans and her panties in one movement and threw them on the floor, leaving her completely naked. He stared at her incredible body, lifted one of her legs and took her foot on his mouth. He licked her heel and back then sucked on her sole, swirling his tongue around her toes; it tasted quite salty, which he found delicious. He did the same to her other foot as she moaned, pointing out that Leonard never did it.

Sheldon started to lick upwards, leaving his hot saliva on her calves and thighs. He insisted for a while on her legs, just to prolong the anticipation, before his mouth finally landed on her juicy lips. He pushed his tongue inside her hole and sucked it, and she had to cover her mouth with one hand to keep herself from screaming like an animal. After all, Leonard and Amy were on the other apartment, and the walls were pretty tiny so they needed to be not too loud.

He kept kissing her beautiful vagina, now licking now gently nipping at it, paying extreme attention not to hurt her, until his erection got way too big to drag on any longer. So he took a break, stood on his knees and unbuttoned his trousers, then he got rid of them together with his underwear and socks.

They were now both naked from head to toe as they stared at each other's eyes, both incredibly excited and nervous at the same time. He leaned towards her and gave her a sloppy kiss.

"Penny..." he said in a low, shaky voice, after their lips separated with a loud smack.

"Yes sweetie?" her voice was nothing more than a whisper now.

"I don't have a condom"

"Don't worry about that, I had my period the day before yesterday, it's completely safe"

"Actually, it isn't 100% safe, but... I want this"

"I want this too, sweetie"

They gave each other a smile and he slowly slid his thick cock inside her pussy. They started passionately making out again as he found his pace, she hugged her arms around his shoulders and wrapped her feet around his waist.

Their eyes closed, their tongues dancing slowly around one another, his member going up and down inside her hole like a Rollercoaster... In that moment nobody and nothing else existed besides them, their pleasure reaching unmeasurable levels.

Feeling she was getting close, Penny suddenly broke the kiss and rolled over him so she was on top. She stood on her knees and kept riding him, grabbing his wrists and putting his hands on her breasts. He squeezed them, then she let go of her grip so his palms could explore the rest of her body.

He moved his hands along her hips, grabbing her ass as it moved and vibrated with her thrusts. Their eyes were now wide open, staring at each other. His hands went upwards, caressing her hips again, her arms and down to her own hands. Their fingers entwined, he felt her wedding ring beneath his fingers and that somehow turned him on even more.

"I want to kiss you again" he said. Their rhythm stopped so they could change position. She stretched her legs and sat facing him while he raised his back and sat up as well. He started to fuck her again, smashing his lips to hers and pressing their bodies together.

Their mutual pleasure was so huge to bring them into another dimension, like a parallel universe with no time and no space or something like that. They sucked on each other's tongue and lips, exploring every inch of each other's mouths as he thrusted deeper and slightly faster inside her, never breaking their passionate kiss except for when they needed to breathe for a few seconds before resuming it.

He was getting very close now. When he felt he wouldn't have lasted much longer he gently pushed her down on her back and laid upon her again, then he kept kissing her mouth, sticking his tongue down her throat and moving his hips inside her while her feet wrapped around his waist once again.

They wanted to make out until their finish. If they didn't, their wild screams would have easily spread through the thin walls, across the hall and to the other apartment. Moaning into each other's mouth was much less noisy and also hotter and sweeter.

He moaned in her mouth and she did just the same as he reached his orgasm, shooting his hot semen in her pussy and making her come as well, their juices mixing together. He finally broke the kiss and rolled off, laying next to her. They were as tired and breathless as if they just finished a marathon, also going through mixed feelings for what they just did.

They were over the moon for finally having showed each other their mutual feelings but, at the same time, they knew they would have to tell Leonard and Amy about it. There was just no way this could be a one-time-only thing.
