Howard staggered out of Penny's apartment at around midday. He had just had the best sex of his life with his gorgeous wife Bernadette. He was still, even after an hour of rest, shaky on his feet.
He walked over to Leonard and Sheldon's apartment. Knocking on the door he remembered Penny's promise to him. He knew he had satisfied his part of the bargain.
After a while of waiting he knocked again, and this time was called in. He opened the door and was greeted by Penny and only Penny. She was behind the kitchen counter.
"Hey, where are the guys?" He asked timidly.
"Oh, Leonard's still trying to calm Sheldon down in his room." She replied.
"Calm him down? Did he see your new ass and freak out?" Howard asked.
"Uh, yeah he did, but I don't think that was the biggest shock to him." She said.
"What else would it... Oh, no you didn't?" He said shocked.
Penny didn't say anything, she just smirked slightly and poured herself a drink.
"Well what happened exactly?" Howard asked.
"He erm, grew... a lot." She replied, she thought back to his giant horse cock and smiled. Turning back to Howard she held her hands apart and showed him.
"Jesus really... lucky bastard." Howard said. He walked over to the counter.
"So, um, I'm off to go get Raj. Thought I'd let him join in on the fun." He said, looking nervously at Penny.
"Is there something else Howard?" She said, moving round the counter. Howard could now see what she was wearing. Dressed in just a tight red top and a set of panties which struggled desperately to contain her monolithic ass.
"Well, I just wanted to check if you still remembered your promise." He said, not looking her in the eyes.
"You mean the promise where if you satisfy your wife, then I would let you have a crack at this." She replied, turning around she spanked her big ass cheeks. Howard watched intently. He gulped and croaked out a reply.
"Yes." He said. Penny smiled and backed up into him. She pressed her ass into his crotch like she did earlier.
"No, I haven't forgotten." With that she started grinding on him. Putting a lot of effort into her moves. He slowly got nudged backwards without realising it. It took Penny a solid minute to nudge him out of the door.
For Howard, it was one of the greatest minutes of his life. As he emerged into the hallway, Penny change her moves. Instead of grinding, she bent her knees slightly and started twerking her massive, soft, round bubble butt on Howard's rock-hard cock. She did this for a solid minute and it drove Howard mental.
He couldn't contain himself. For years he had idealised this woman as a goddess, and now she was voluntarily twerking her huge ass on him.
"Uh god... Penny." He said. Penny recognised this. She knew Howard was about to cum. She immediately stopped what she was doing and spun round. She quickly unbuckled his belt and lowered his trousers and boxers. Out popped his hard ten-inch cock. She grasped it just in time and quickly engulfed his cock head.
"Uh YES!!" Howard yelled. He started cumming in Penny's mouth. Whereas before the drug, she would have struggled to handle this much cum. After both Leonard and Sheldon, she was able to easily swallow the six loads Howard released. It tasted quite nice to her and it was great for a nice lunch snack. Withdrawing his now softening cock from her mouth. She laughed internally to herself. She just realised that the only thing she had swallowed today was cum.
"And that was just me twerking and grinding." She said to him with a wink. With that she walked back inside and closed the door.
Howard stood there, breathing heavily. He couldn't believe it. He tucked himself in and buckled up his trousers and turned to walk down the stairs.
"Leonard is one lucky bastard." He thought.
(Meanwhile back in Leonard's apartment)
Leonard walked down the hall of his apartment. He looked up to see Penny closing the front door behind her.
"Where have you been?" He asked. He walked behind the kitchen counter.
"Nowhere." Penny said. Smiling to herself. She sauntered over to Leonard and kissed him.
"Sheldon is asking for you." He said, watching her big ass shake as she moved back round the counter.
"Said that he needed to talk to you about all this." He said.
"Okay, do you think I should get changed first?" She replied, innocently.
"Maybe, throw on some pants." He replied. She smiled and walked down the hall to Leonard's room to fetch her jeans.
Leonard made himself a drink and went to sit down in the armchair. He heard Penny go into his room. Then heard her leave and go into Sheldon's room.
He sat there for several minutes before he heard a knock at the door. He got up and went to see who it was. He opened the door and saw Bernadette for the first time that day.
His eyes shot open as he saw the buxom, blonde before him.
"Hey Leonard, I was just wondering if I could come in and talk to Penny?" She asked timidly.
