No, the lovers are too wrapped up in themselves

Haley and Dylan lay exhausted on top of the washing machine for awhile until the cycle ended. They untangled their bodies and helped each other stand, Haleys legs buckled slightly as she stood up. Once she had regained her balance she took his soaking wet jeans and boxers out of the washing machine, "hmmmmm, instead of waiting for these to dry in the tumble dryer why don't we go over to my granddads and dry them in the sun. We could go swimming" suggested Haley.
"Sounds good, but I can't go out without any pants" Dylan complained.
"That hasn't always stopped you before" replied Haley smiling "why don't I get you some of dads swimming trunks, they'll just look like normal shorts if anyone sees you." Learning Haley's plan and knowing her daughter would get her own way Claire formulated a plan of her own, unseen by Haley and Dylan a dishevelled Claire crept back up the stairs leaving the basement and once clear she rushed to her bedroom.
"Ok, I guess, you know I love fooling around in the pool with you" Dylan replied.
"Oh no, no more fooling around, my grandad told me he was taking Manny and Joe out all day fishing but Gloria might be around."
"Ok" agreed Dylan, as he pulled on his t-shirt which at the moment was the only dry piece of clothing he had. He felt satisfied for the moment but knew once at the pool if the situation was right there was every chance Haley would change her mind and fool around, besides even if Haley didn't want to then Gloria, who in his opinion was the hottest Latina MILF he’d ever seen, might be there to gawp at.
Haley put on her bra and fixed her dress, she picked up her thong and feeling how damp it was with her own wetness and not wanting to wear them while they were wet she placed them on top of the washing machine planning to wash them later. “Ok, I'll check the coast is clear" declared Haley as she picked up her cardigan on the way out of the basement Dylan picked up his wet clothes, he placed his phone, keys and wallet on top of them. After a brief hesitation he also took Haleys thong when she wasn't looking and hid it amongst his own clothes. He followed her out of the basement.

Claire realised a few things. Firstly, her panties were wet, so she removed them and left them on the bed. They'd give Phil a thrill when he found them and she'd lie and tell him that she'd been thinking of him. If Dylan found them then all the better. Secondly, she was a pervert who had been thrilled to watch her own daughter in a private sex show, this disturbed her. Thirdly, she wouldn't be satisfied until she'd fucked Dylan herself. Fourthly, she was covered in sweat, she couldn't go for another bath so a swim would be a great way to relax, unwind and get clean. Lastly, if she was going to see Dylan at the pool then she'd make sure he was wearing what she wanted him to. She hid all of Phil’s swimming trunks making sure the only ones Haley would find would be a pair of tight speedos Phil had bought as a joke. She grinned at completing the first part if her plan and grabbed her skimpiest bikini.

Download complete Alex carefully disconnected Haleys phone from the computer, she deleted the picture she had sent, locked the phone and placed it back on her sisters bed. She cleaned the dildo and put everything back in the box. She cleaned up the wet stains on her chair and bed as best she could. She decided to have a shower and wash the sweat off her so she threw the clothes she had been wearing into the wash basket and grabbed her bathrobe, she paused to examine the room and satisfied there was no evidence of what she had been doing she unlocked the door and stepped into the hallway while tying her bathrobe closed.

Haley was creeping along the hallway and was nearing her room when the door opened and Alex collided into her. They both fell on the ground in a tangle of limbs with Alex landing on top. Haley was distraught, when Alex had knocked her over Alex's bathrobe had opened and Haley now had a face of large breasts and to make matters worse her own dress had been pushed up her body meaning their pussies were touching. Their struggling to untangle themselves just meant their bodies kept rubbing against each other.

Dylan was amazed at the sight before him, when the sisters had collided and fallen over Haleys dress had ridden up her body and Alex's bathrobe had opened up, then lifted over her head. The result was that he had a perfect view of Alex's round ass and both sisters wet pussies (he had no idea that he been responsible for Alex's earlier arousal). The sight of these two sexy sisters naked from the waist down rubbing against each other and moaning as they tried to get up was a phenomenal and his cock grew immediately hard. "Help us!" came the muffled cry from Haley from in between Alex's breasts. Dylan who had been admiring the view of the sisters entwined before him reacted automatically as his natural good manners kicked in. Forgetting that he wasn’t wearing anything but a t-shirt he dropped the clothes in his hands and reached down to pull Alex off of Haley.
