Do as she asks

You grab your cock and point it into her cunt. She moans as you enter her with the tip. You hold her ass as you thrust forward. She growls at your penetration. You grunt. You bounce her ass off the wall as you pound your cock deep within her. "You will let me come inside you. Unh! You will come when I come. Oh! You will come harder than you've ever come before. Ah!"

"Yes, Jim! Yes! Yes! Fuck me, yes!"

As you thrust in and out of her tight pussy, you feel your spunk starting to rise in your cock. You double your rhythm, trying to get off as fast as you can. As you explode in Jill's pussy, she screams her own orgasm. You can feel her muscles squeezing you tightly, stopping your thrusts completely. You groan as you unload your jism into her womb. Your bodies jerk and writhe through your mutual climax.

"Oh, Jim. That was fantastic. I always knew you'd make me happy and could fuck like a bull."

"You were wonderful, too, Jill. I need to leave now." She pouts. "Jill, you will finish your shower in here. When you hear the door close again, you will forget what we did in here, though you will still get horny and wet if you see me again."

"Okay, Jim."

You step out of the shower, grabbing a towel form the rack, and toweling yourself off. Timmy is still looking straight ahead. You get into your swimsuit. Then you squat down in front of Timmy. Jill is humming in the shower.

"Timmy, when the door closes again, you will forget everything that happened in here. You only remember your mom coming in with you to take a shower."

"Okay, Jim."

You take your clothes and leave the changing room. You walk to the middle of the row of lockers. Two men and a young girl are at the far end, putting a little girl's coat in the locker. Probably a gay couple or something. As you put your clothes in the locker, Jill and Timmy come out of the shower. She looks at you and flushes. Then she turns to their locker, puts the clothes away, and walks through the door to the pool area. She looks over her shoulder at you before the door closes.
