On a hot summer day, it is great to have friends with a swimming pool. That was exactly what Andrew was thinking while leisurely floating around in Stuart's pool.
"I've had enough for now, I'm getting out," Stuart called.
"Good idea, I'm getting pretty hungry also, so how about we head out and grab food from somewhere?" replied Andrew.
"Sounds like a plan," Stuart said approvingly.
The two had climbed out of the pool and Stuart had grabbed his towel off one of the chairs next to the pool when Andrew realised that he hadn't brought a towel with him when he came around.
"Hey can I borrow a towel, I've forgotten mine."
"Sorry but today is laundry day so all my towels are in the wash and this is my last one." Stuart stated apologetically.
"Well, I have to dry off first before we go anywhere so any ideas?" asked Andrew.
Stuart responded, "You can always just take the swimmers off and dry off in the sun." Stuart added, "I wouldn't mind working on my tan so if it makes you happier, I'll do the same".
Andrew considered this for a moment before replying with "Um, yeah sure, why not?"
The two stripped off the wet clothes and laid back in the sun, allowing the warmth of the sun to dry them. Andrew looked over at Stuart who was lying back with his eyes close and almost drifting off to sleep. Andrew noted that he had a fairly similar build to his own; tall athletic build, lean but well defined muscles and short sandy blonde hair. He also noted Stuart's penis which was cleanly shaven and of the same tanned skin tone as the rest of his body which suggested to Andrew that naked sunbaking wasn't a rare occurrence for Stuart. Andrew's thoughts were interrupted by Stuart's laughing remark.
"Like what you see?"
"What?" was Andrew's puzzled reply.
"You were staring at my cock. Haven't you seen one as big as it before?" Stuart asked cheekily.
"Fuck off. My dick is like a tree trunk in comparison to your prick." Andrew quickly joked back.
"Prove it." Stuart stated in a challenging tone.
"What do you mean?" Andrew asked in reply.
"How about we see whose cock is bigger? Or are you scared you won't even come close?"
Andrew wasn't sure how to answer straight away. He didn't have a problem with Stuart seeing his penis as the two had been friends for a long time and on more than a few occasions they had seen each other naked but to compare themselves in such a way was a bit of a strange idea to him. After a quick pause to think it over, however, curiosity got the better of him and Andrew always considered himself up for a challenge.
"Ok, let's do it" Was Andrew's confident reply.
"Excellent." Stuart chuckled, "let's go."
While a bit of a strange feeling at first, Andrew took his cock in hand and started to stroke it in an effort to get it hard. Stuart didn't take much time at all and after only a few minutes, his cock was at full erection and he was still working it while watching Andrew finally get his erection to its maximum size. It was clear that Andrew's penis was slightly larger and thicker than Stuart's but Stuart's ball sack was definitely larger and hung lower. As he jerked his cock, his balls swung like golf balls in a sock.
"Looks like I'm bigger" Andrew heartily boasted.
"Yeah but chicks dig my bigger balls" Stuart stated.
As the two guys continued to discuss their assets, a car pulled into the driveway out the front of Stuart's house. Chloe, Stuart's girlfriend, had decided to drop by and make use of the great weather to have a dip in Stuart's pool and she also hoped they might even have some extra aquatic activity after. Chloe had always wanted to try sex in a pool and the thought that she might finally get to try it had been driving her crazy all morning while she finished some errands for the day before heading over to Stuart's. She felt like pulling up her skirt and giving herself a quick pleasure session before going in but the driveway was quite exposed so she thought it best to hold back for after the swim so she grabbed her bag, slipped out of the car and confidently strode around the side of the house to the pool.
Neither Andrew or Stuart had heard Chloe's car arrive and they were both still sporting full erections and arguing about whether penis length or ball size were important when Chloe walked around into the pool area and interrupted them with a loud gasp.
"What are you two doing!?" she stammered.
