This is almost an epilogue to Chapter 3 and picks up shortly after Sam left Anna and Robert and their sunbathing afternoon in the flat.
Anna sent Sam a message to let her know when he was home. He had started to walk slower as his cock stirred again at the thought of her and Robert. He hoped the younger man had his erection tended to by Anna as he felt a bit guilty that he had received a lovely handjob from the young woman while her lover was left hard.
He arrived home and stripped off, as he usually did on a warm day. His flat was on the top floor, so couldn't be seen easily and the few windows that faced public areas had net curtains to block anyone who could get a glimpse.
He sent Anna a message and a photo arrived shortly afterwards. It was her thumb. His cock stirred, despite having shot a massive load just over an hour ago. The thumb was nothing special, but he knew. He looked closer and the dried crust of his sperm was on it. It was the thumb Anna had rubbed over his cock after he had ejaculated, she had wiped the head clean with it after squeezing the last of the cum from his penis.
Sam sat on the sofa, his cock getting harder as he replayed the events in his mind, staring at the thumb photo as proof he had been wanked off as he held Anna's breast. He closed his eyes and leant back, slowly stroking his cock as he thought of looking at the other photos, the ones showing Anna's breasts.
The telephone rang, Anna calling. He wondered if he should get dressed, but she was used to him naked now, so just answered it, his face and bare chest on display to her.
"Hi Sam, hope you are ok." She sounded out of breath and it took Sam a few moments to realise she was lying down.
She adjusted the position of her phone so it showed her face and the top of her chest, the nipples just out of shot, but the top of the breasts showing well.
Anna was looking at Sam, well, at the camera in her phone, Her lips were parted and her breathing heavy. She groaned and her eyelids flickered.
"Robert is eating me out, Sam" she moaned.
Sam stared at the screen, her eyes were dreamy now, lids closing as her mouth formed unheard words, only strange little noises coming from her throat.
"He is a lucky man." Added Sam, dreaming of what this girl's lovely pussy would look and taste like.
"I am lucky too, Sam" she breathed and her head went back, letting the nipples come into the frame, hard, red and quivering as her breasts shook. She stared at the screen again, "he is very good at this."
Sam was hard again now and started to stroke as he watched Anna in ecstasy.
She looked at him through the phone and smiled "So good" she moaned and closed her eyes as she groaned.
Sam put the telephone down on the table at the side, the usual position when he would masturbate for her. He could see her clearly and she could see most of his body and watch him stroking his hard cock for her.
"So nice" she repeated as she watched him take his hard shaft in his hand and pull upwards, the foreskin spreading the pre-cum over the swollen head to make it shine in the light.
Sam could hear Robert, the lapping sound of his tongue as he drank Anna's juice. Anna was panting now, her bare breasts on show as her back arched up with joy. She turned again and looked at the older man as he masturbated to the show.
"I am close, Sam." She was panting as she spoke and then let out a growling noise and tilted her head back, breasts shaking as her body started to twitch.
"So close" she gasped and turned to look at Sam.
"Good," he replied, "good. I want to see you."
Anna's head went back and her chest raised, shaking as it showed all of her breasts to the camera. Her mouth opened and a groaning cry came out. Her eyes were closed now and she shuddered and groaned loudly. Then she turned to look at Sam, smiled, closed her eyes again and let out long moan.
"Yes," came the older man's voice, "yes Anna."
She moaned and shuddered again before her body went slightly limp, mouth wide as she gasped for breath.
"Yes." she repeated back to the man watching.
Sam watched her recover, her lover moving up to kiss he mouth, his face wet from her. Sam sighed and began to stroke more as both the younger couple watched.
Robert picked up the telephone and watched Sam. "Looking good, Sam." he said, amazed that the older man was hard so quickly. Then he handed the phone back to his lover. She had shifted position and was lying prone on the bed, her face filling the screen, but Sam's eyes were trying to look at her hanging breasts, so she moved the phone to let him see them, slightly flattened on the bed.
"So nice" she whispered to Sam as she watched him masturbate, "so nice."
"You looked amazing." Sam said, his breath heavy now.
