Miss: You go off half-cocked!

It all seemed so much easier when you and Sarah were on the tail end of a nice high from Sarah and Shasta's weed. Something's different, the bed, or Mary Forbes' eager attention, but you and Sarah have trouble getting a good rhythm going. You get into her, you get going, and each time you think you've got it, Sarah pumps her hips back enthusiastically, you miss a stroke, and pop! you're out again.

"Easy, sweet angel," Mary tells Sarah. Mary lays a hand on Sarah's lower back. "You just stay right where you are and I'll put Tom back inside."

Mary reaches down and takes a good grip round your shaft. But as her fingers close round your cock, you grunt, "Oh!", your cock swells, and you shoot your cum over Sarah's cunt, ass, and butt cheeks.

Sarah giggles. "Did you just cum, Tom?" she asked.

"A regular gusher!" Mary says. She laughs. I suppose I can still do my part!"

"Sure, Mom!" Sarah says.

"Tom, hon, will you fetch me one of those wipes from the blue and white box?" she asks you. You hand her a moistened wipe with a faint lemon scent. "All right, Sarah, just getting a little bit here," she says. Mary wipes your cum off Sarah's butthole.

"Ooh, tickles!" Sarah says.

Mary squints her eyes at her work. "There, clean." she sighs. "I thought I was done with wiping you girls' poop holes for good," Mary says. "But I suppose it's a small price to pay. Outside that nasty little hole, you're really beautiful, Sarah. Really lovely. I want to eat you again right now."

"Please, Mom," Sarah says.
