Later, your sister convinces your mom to take a dip with you

Eavesdropping on your sister and mom's conversation fortunately had put a damper on your arousal for the moment, so were able to walk back out without embarrassment. You served up the burgers and sat down with your family for some enjoyable food and conversation.

Now that your sister had got past her initial prejudices toward your mom's new place (and body), she was pretty relaxed and easygoing. And that obviously made your mom happy. "I'm glad you guys came over," she gushed. "Maybe we can do something like this regularly. Have a 'family' day - or night - for us, and hopefully David."

"yeah, that'd be cool," Tabitha said with typical tween lack of enthusiasm. "Or maybe you and I can do something," she suggested with a little more energy. "I see Tim all the time, and you two can get together easy enough whenever you want. But I'd like to see you."

Your mom hesitated and looked at you. "Uh, sure," she said, "we can do that too."

You shrugged. "I'm happy to see you any time, mom. I can drive over any evening during the week. Just let me know when..."

"Okay..." she said. "We'll have some 'girl time' for Tabitha and myself. Tim and I will probably see each other more anyway. But I do want to spend some time together as a family as well."

Tabitha snorted. "Good luck catching David. I hardly see him now. And he doesn't really want to, uh..." she trailed off, realized that your mom was very much hurt by David's disdain.

Your mom smiled sadly. "I hope David will come around eventually. But I am glad to have the two of you here."

The conversation became lighter and you finished your meal.Tabitha immediately dove back into the pool and pleaded with you both to join her. You said you would once you cleaned off the grill. Your mom was still **** but Tabitha begged and cajoled, asking her to come in and toss the beach ball. She glanced over at you questioningly. You frowned. "Mom, get it pool! You know I don't care what you look like. It's your pool - and your body. Enjoy yourself!"

She gave a tentative smile, then looked back at Tabby. "Okay, Tabitha, prepare yourself for a thorough trouncing!"

You hadn't seen your mom in such a good mood in a long time - but your happiness for your mom quickly turned to lust when she shimmied out of her denim shorts and lifted her tank top over her head. She wore a pink bikini that was probably surprisingly tasteful Stephanie. But it still displayed her incredible curves as no bikini could really contain her oversized breasts and plump ass. She stooped down by the edge of the pool to reach for the beach ball, pushing an inflatable shark float out of the way. She looked back over her should at you. "Tim, don't worry with that too much. The grill can wait. Come on in the water!"

For a brief moment, you could swear her expression was sultry, beckoning you as she called out in a sexy tone "come on....". You shook your head and the vision passed. "God!!" you muttered to yourself. "What's happening to me? This is my mom!" But at the moment she didn't look anything like your mother, and your body automatically reacted to her scantily-clad form. Your penis jumped to attention, sticking nearly straight out in your trunks. You kept the grill between your body and the pool so your mother couldn't see. "Uh, that's okay, I'll be done in a minute," you stuttered. "Go on and play with Tabby," you encouraged.

She said "suit yourself," and with an all-too-sexy shrug she jumped in.

Seeing her body wet did not help matters. You squeezed your dick between your legs, trying to control yourself. You hurriedly finished cleaning the grill and, when Tabitha and your mom weren't looking, quickly ran to the pool and jumped in. You hoped the water would cool your ardor, but your erection didn't subside. You tried to hide it as long as you could, but then you got in the middle of a water fight between Tabitha and your mom. Tabitha jumped on your back, pushing you into your mom - where your penis poked into her ass, almost between her cheeks.

Your mom's reaction wasn't what you expected, however - instead of completely freaking out...
