We are driving home from theater. "He's a great host aunt Nita. We get along so good. I love you all so much for letting me stay this summer."
"You know you're welcome here anytime. We love having you." Mom says.
We get home it's about supper time. While Jo and mom fix supper. I decide to mow the yard. Before dad says I'm neglecting my chores.
I come in drenched in sweat. "Anyone need the bathroom I'm going to shower." They both say no.
I start to just get soaped up and jack off thinking of what happened at the movie. I am so engrossed. I don't hear the bathroom door open. I'm startled by the shower door being opened. I jump like I'm shot.
There is Jo smiling.
"What the fuck!"
"Your mom went for milk. I just had to get a better look at that huge cock of yours. From the looks of things you were busy. Don't let me stop you. I'd love to watch. Fuck it's huge."
I'm actually losing my erection.
"Come on hurry. Your mom will be back soon."
"Dam Jo I can't with you watching."
"Too bad I really wanted to watch. I have never seen a guy jerk off."
"Well it's not happening now either."
She just smiles "Well I could do it for you." reaching for my dick.
"Fuck no! We are dead meat if mom catches us."
She sighs, "Maybe another time."
"Maybe, now get out of here."
She leaves giggling. I finish up showering. No way can I get it back up after that.
I emerge from the bathroom passing through the kitchen.
"Feel better?" asks Jo giving me a knowing grin.
"Oh hell yea."
We eat supper. Then I go to the front room. Flop down on the couch in front of the fan. It must be 100 in the shade. The fan 3' away doesn't really help much.
Jo comes in saying, "Get up and share the fan."
"I got here first, so it's mine."
"We will see about that." Then grabs my feet pulling me off the couch. Then she jumps on it, laughing at me. I grab her arm dragging her off. She grabs my leg and I go down. She quickly climbs on top of me. Sitting on my waist rubbing her crotch on my dick through my shorts. She pins my arms over my head. This puts her tits right in my face.
