Unspoken Pleasure by Erotica

Use Your Sisters Instead: EP2

Mary bought a big calendar and tacked it up on the fridge. Then she made each of the girls mark down their cycles so that they could determine their safe days. You'd think she was asking them to choose which finger they wanted to cut off, for all their complaining.

Mary knew better than to ask Michael to be regular about his activities. They would all have to play by ear and figure things out as they went. Fortunately, all three girls lived at home and they all had different schedules with school, extracurricular activities and, of course, church. That meant at least one sister would be available at all times.

With everything set up, Mary wanted to get things started as soon as possible. Fortunately, her son was on the same wavelength. That very next evening, after dinner, she heard music blaring in Michael's room. Her favorite scented hand lotion was missing from her bathroom. All the signs were there. Mary opened the door and, sure enough, there was Michael lying back on his bed. Pants around his ankles. Penis in his palm.

Mary had heard boys liked to look at pictures when they did it, but her son just had his eyes squeezed shut. His body twisted in rising pleasure. He was whispering a word that sounded a bit like 'Tabitha,' but Mary couldn't be sure. Michael's eyes popped open when his mother walked in the room. "Holy... Mom! I told you not to bother me when I'm... When my door is shut."

"And I told you what to do the next time you masturbate," Mary said. She crossed her arms with disdain. Michael lay back, looking shocked. His penis was still in his fist, pulsing and purple.

"Well, come on then," Mary said, "Let's get this over with. Unless you need more time."

"No! I mean. No it's pretty close."

"Good," Mary said, "Let's go find your sister."

"You mean Tabitha?" Michael asked, hopefully. Mary eyed him warily. One sister shouldn't be any more desirable than another. In any case, Tabitha was at volleyball practice and Hope had a night class. But fortunately Chastity was in her room and almost certainly ready to help.

"Maybe I'll wait," Michael said, "I'm pretty sure Chastity hates me."

"Chastity doesn't hate you," Mary said, "She just has a unique way of expressing her feelings." Michael looked ready to protest more, so she grabbed her son by the arm, dragged him out of his room, and marched him down the hall. "Chastity is going to be so mad," Michael said.

"Of course she won't. If anything, she'd be angrier if you didn't let her help you. You'll see." Mary knocked on Chastity's door (a courtesy she hadn't given her son) and then opened the door.

Chastity was lying back on her bed, reading a book. She was wearing a conservative set of pajamas - red black plaid with long sleeves that almost looked like a little bedroom business suit. Chastity's golden curls splayed out on the pillow behind her.

the same size as her husband's, Mary noticed. Perhaps a bit longer and definitely thicker. A very nice penis that would someday give Michael's future wife a lot of healthy babies.

gave her brother a look - it was supposed to be nasty, but it came out as kind of pleased. Mary had to admit, her daughter's breasts were quite big. Yet they still had the perkiness of youth. Her little pink nipples poked outward. It occurred to Mary that her daughter didn't actually need to take her top off for this, but it was too late by that point. Plus it seemed to be working for Michael. He was rubbing himself much faster. Chastity slid
