*****
Matthew decided to go for a swim in the pool in the outside garden to cool down after his hard workout. He was very happy with how his body was coming on; he had a muscular physique with defined pecs and abs and thick muscle-bound arms and legs. Matthew walked outside wearing just his boxers; their house was isolated with just one neighbour nearby and he wasn't worried about anyone seeing him.
Matthew swam a few laps before getting out of the pool and laying on a lounger to soak up some sun. He pushed his wavy blonde hair out of his eyes and put on some sunglasses. After a minute he heard a noise near the fence between his garden and the neighbours. He walked over to the fence and saw someone backing away - it was his neighbor Ava. Ava was 5 foot 7 inches tall, had long black hair and was 18 years old. She had her hand in her bikini panties.
"Matthew, I was just... Hi, how are you", she quickly removed her hand.
"I'm good", Matthew replied distractedly, looking at Ava's tits barely covered by a bikini.
Ava had a great body and he sometimes watched her sunbathing from his bedroom window. He had jerked off multiple times watching her lay in her garden barely wearing anything. And it looked like she was doing the same thing to him.
"We're you just..." Matthew asked, looking at her flushed face. She hesitated, her face getting even redder, before nodding sheepishly.
Matthew looked at her fit, toned body again before saying "Come over here".
Ava hesitated before complying. As soon as she stood before him, Matthew pulled her forward by her hips and kissed her. She let out a startled noise before wrapping her arms around his neck, melting into the kiss. Matthew had about 5 inches on her and she had to stretch to meet his mouth. Matthew bent down without breaking mouth contact and picked Ava up so that her legs were wrapped around his waist. When he pressed her back against the fence and deepened the kiss, his tongue entering her mouth, and she felt his hard arousal against her stomach.
Matthew broke the kiss and let her down, saying "Let me take care of that for you".
He led her over to sun lounger and knelt down before her, removing her panties and bikini. He'd always fantasized about doing this to Ava, and here she was, her wet, hairless crotch right in front of his face. He wasted no time and licked from her opening up to her clit. Ava let out a whimper at the sensation and drew her hand through his soft wavy hair.
