A trip to the park, and maybe the neighborhood glory holes

"C'mon, Mom, let's get going." You grab her by the arm, leading her out of the shower and then into the hall.

"Wait! I don't have my towel, we're dripping everywhere, just--"

"I said c'mon," you growl, giving her big, glistening ass a spank. "It's warm out; you'll be fine."

"W-wuh... We're not getting dressed first?" As you reach the top of the stairs, she glances at you nervously. "Not even some luh, um... Lun, lunderwear..."

"You mean lingerie?" She shrugs, so you try again. "One of your cumslut outfits?"

"Y-yeah," she stammers, blushing. "Maybe one that covers my whole body, this time?"

"...Fine, I guess I should grab something for myself anyway. Go hang out with Cassidy, see if he wants to come."

With that you let her go, reluctantly turning away from her naked body as you head back upstairs.

You hear Cassidy's voice form around the corner. "Sup Mom--Oh, heeey there. Looking for more action?"

"What? No, I mean, Marcus didn't--"

"A whole shower together and he didn't make a donation? Selfish bastard," your brother chuckles. "I'm in the middle of a game, but why don't you crawl your ass over here and see if you can suck a drop or two out?"

The last thing you hear before entering your room is the thud of Mom's knees hitting the floor.

Once you're inside, you throw on a T-shirt and a loose pair of shorts. No underwear required: why put more barriers between you and your cumdump? Then you pick out something for Mom, ending up with a black mesh bodysuit. It does cover her whole body... Depending on how you define "cover," anyway. There's also a hole for her tits and another for her pussy, so it won't be getting in the way of your plans.

Hurrying back downstairs, you walk in on Mom blowing Cassidy. She's on all fours between his legs, trying to **** his sizable cock down her throat as he continues playing an online shooter.

"Deeper, Mom. Don't slack off now," he grunts, before pausing for a moment. "...Huh? Oh, sorry, didn't know my mic was on... Yeah, just getting a quick blowjob. Well, I mean, it won't be so quick if my stupid fuckin' Mom keeps doing such an amateur job," he snaps, glancing downward. "Deeper!"

"Sshu-ggh," your mother sputters into Cassidy's crotch, a few drops of drool trickling down her chin.

"Hmm? What do you mean, 'is she my real mom?' Why wouldn't she be?" There's another pause as Cassidy's teammate responds. "Whatever, Man. I've seen your mom, and you're definitely missing out. Bet your dad treats that body like a jizz bucket 24/7." A moment passes, then he laughs. "Yeah, Dude, that's what I thought."

"Hate to interrupt," you say from the doorway. "Mom and I were gonna hit the town for a little bit. Wanna come?"

"Dunno, where ya going?"

"Hmm... Maybe just for a walk. The park's nice this time of day."

Cassidy grins, catching your drift immediately. The local park is a hotspot for women in need of a donation, and for the perverts that are oh-so-happy to oblige. A few months ago, someone went into the public bathrooms and drilled a bunch of glory holes in the wall between the male and female sides. At least a couple of them are in use at any given time, day or night. It's a favorite spot of Cassidy's, whenever he gets bored of Mom or Dad is feeling touchy.

"You're taking Mom, though," he replies, smirking. "You looking for some holes, or sharing ours?"

Your mother makes an angry noise and tries to pull away... But Cassidy happens to be waiting to respawn, so he has a free hand to hold her down.

"Both, probably," you reply, rubbing your erection through the thin fabric of your shorts. As it reaches its full length, the tip pops out the bottom the left leg.

"I'm in," Cassidy says. "Game's almost over, and I might save this load for--Uh, I mean, I might not be able to bust one out right now. Sorry, Mom."

She pulls away, a trail of slime connecting her lips and your brother's cock. "Guuuch... Ugh... It, it's okay, Sweetie. Maybe soon?"

"Yeah, sure," he replies, quitting the game and standing up. "Oh hey, nice outfit choice Marcus."

You hold up the bodysuit. "Mine, or hers?"

"Both, Dude. I'll grab some shorts or something while you squeeze her into that."

It takes some doing, but you manage to fit your mother's huge tits and fat ass into the skimpy bodysuit. She looks about as embarrassed as you might expect, trying in vain to cover herself up as you lead her out onto the front porch.

Cassidy follows a few seconds later, and your happy little family heads off towards the park.
