An unexpected call.

Mari slid off of the young repairman, kneeling between his thighs, so she could wrap her lips around his thick shaft. She bobbed her head up and down over his loins to ensure he was hard.

"It is not over," she smirked after popping his erection from her mouth. She climbed over him, with her heavy breasts dangling over his chest. "Do not worry, I will put it in slowly..." she whispered in his ear. "Today is a safe day. You can put it in me raw."

Dr. Sugimoto switched to another camera so she could see Mari lower herself down onto the young man's await cock.

"Aaaah, you are so big!" Mari cried out as her pussy slowly engulfed his thick shaft. She teasingly licked his right earlobe and he let out a low groan.

"Please give me that big cock," she moaned as she sat upright, resting her hands on his stomach. "Deep into my pussy!"

Just as the young repairman pushed his hips up to drive the full length of his cock into Mari's cunt, her iPhone rang. "Ah! Not yet!" she gasped. Panicking she reached over to try to hang up but accidentally hit the video chat button, displaying her husband's face on the screen.

"Hm? Oh, your camera is on," Kôji noted.

Mari stared down at her phone, which luckily was knocked aside so that its front-facing camera was facing the wall. She quickly pulled her shirt over her breasts out of modesty before grabbing her phone. She put her finger to her lips and whispered to the young repairman, "Shhhh! Stay quiet..."

"Hello, dear," she smiled, waving at her husband.

"Oh, my Mari-chan! I can see your beautiful face!" he replied.

"Is your meeting going okay?" she asked as she started to do short bounces on the young repairman's lap.

"Yes, it was decided right away," Kôji chirped. "My boss is very pleased. Hahahaha!"

"I...I am very happy for you," she smiled.

"Technology is very impressive," he noted, "I can see you very clearly."

"Y...yes, I can see you clearly as well," she replied while continuing to ride on the young man's big cock.

"You do not seem to be thrilled that I called?" Kôji wondered.

"N...not at all," she smiled. "I am really happy."

"Hmmm? Are you sweating?" her husband said, leaning closer to his phone. "The screen is shaking too!"

Mari bit her lip to stifle a moan.

"Are you feeling alright?" he asked.

"No, I am fine," she nodded. "I... I have put on some weight recently so I am exercising."

"I see. I see," Kôji nodded. "But you are not pushing yourself?"

Mari stopped moving for a moment as a shiver went coursed through her body from her loins to her head. "It... it is for your sake, Kôji," she replied as she resumed moving up and down on the young repairman's cock. "You do not want a fat wife, right?"

"Women are the best with some meat on them," her husband chuckled. "You are very sex as you are, Mari-chan."

"Oh, no... I...I cannot... stop my waist..." she mumbled, covering her mouth with her left hand to try to suppress another moan.

"Hmm? What did you just say?" Kôji asked.

"I...I am just exercising, Kôji-san," she answered. "Please tell me more about your meeting..."

Kôji droned on about his meeting and his wife politely listened with occasional "Yes..." and "That is right..." while bouncing on another man's cock out of view of the camera.

Mari stopped bouncing to let the young repairman's cock slip out. She leaned over him, out of her phone camera's view, and whispered, "Stop and stay still!"

"What for?" Kôji wondered.

"Oh, I... I was not talking to you, Kôji-san," she replied, only to out a sudden gasp when the young repairman drove his cock into her pussy in one hard stroke.

"Oh, what happened?" her husband asked.

"Hic... my hiccups..." she answered, closing her eyes shut. "They will not stop..."

"Gulp down some water," he suggested.

"Oh!" she gasped again when she felt the young repairman's cock drive upwards again.

"Are you really exercising?" Kôji wondered.

"Oh... one... two... one... two..." Mari answered as she moved her arms, pretending to stretch.

"Mari-san!" her husband exclaimed.

"I... I hit the wall..." she sighed.

"You seem kind of sexy with the sweat," Kôji chuckled.

"Yes... thank you..." she smiled weakly. "I... I cannot hold back... OH!"

"What is it?"

"I need to pee..." she whined.

"It is not healthy to hold it in, Mari-chan," he told her.

"I... I am going to..." she moaned.

"Hurry up and go," her husband huffed.

"I... need to go shopping..."

"You are not going to the bathroom?" he quizzed.

"OH!" Mari gasped when the young repairman stabbed her hard with his cock. She then let out a low agonizing moan.

"Mari-chan is in danger?" Kôji yelped. "I am going to call an ambulance!"

"No, I am okay!" Mari blurted out, shaking her head. "I am hanging up now."

"Oh no, Mari-chan..." her husband cried out, trying to stop her but she ended the call.

"Oh, baka! Baka! Baka!" Mari growled, weakly slapping the young repairman's chest with her well manicured hands.

He chuckled and playfully thrust upwards again to cause her to moan.

"So you are going to be like that..." she whispered, pulling her shirt over head to free her huge tits before leaning over him. "Well then, how about I get a little more serious..."
