"Helena..."
"Hst!" The slim strawberry blonde silenced Del with a wave of her arm before ushering him into her bedroom and closing the door behind him. "I said you were mine after Mom was done with you."
He sat on her bed. "I'm wasted. Those women..." He stopped. Helena dropped the robe she had been wearing, revealing the same garters and hose from the previous day, but now she was also wearing a dark, sheer bustier that propped up her B-cup breasts and deepened her cleavage. "...whoa."
The eighteen-year-old blushed for a moment as Del stared at her outfit, but then took a breath. "So, get those pants off."
He unfastened his jeans. "Sure, but nothing's gonna happen; I've been wrung dry."
"We'll see about that. Also, whisper if you have to say anything." She gave a pointed look toward the air vent near the ceiling. "The walls have ears."
He glanced at the vent and then sat back on her bed. As expected, his penis was limp and lifeless.
Helena climbed onto the bed with him. "You don't like how I look?" She seemed offended.
"You're gorgeous, totally sexy," Del replied, "but holy shit those women got two loads out of me, back-to-back. I may not be able to cum again for days."
"Lay back."
He did so, sighing, and Helena moved her nylon-covered feet to his penis again. However, unlike last time, it just didn't respond to the manipulations of her dainty tootsies. She finally gave up. "Damnit," she swore under her breath, "Mom just can't let me enjoy myself." She moved up the bed and lay back on a pillow, huffing in frustration.
Del lay down beside her. "How do you mean?"
"She keeps telling me how much I'm like her, a goddamn cumslut, useless for anything but sex, and now I can't even get that going because she drained you like a fucking vampire."
"She said all that?!"
"Shh!" She waved her hand at the air vent.
He moved closer so he could whisper. "So the ice princess and dominatrix acts are because of what your mom says? You don't have to listen to her. Did you blackmail me because you thought I wouldn't be interested in you otherwise?"
She looked into his eyes as they lay there. "Well, yeah. When we met, I treated you like shit I found on the bottom of my shoe."
He considered for a moment. "Tell me something you like, a hobby or pastime."
She thought for a moment. "I like anime."
"Me too! Attack on Titan, My Hero Academia..."
"Assassination Classroom?"
"Yeah! See, we have something in common. And that's just one thing...I'm sure we have others, but you never bothered to find out." He peered out the window into the night. "Why were you looking at Nancy's house so early in the morning, when you caught us...doing that?"
She looked embarrassed. "I always look out there when I wake up. Sometimes I see you heading to school."
"You've been watching me?"
She flushed. "Yeah...and when you're doing stuff with Mom..."
"You've been spying, too." Del marveled at this...both Nancy and Helena had spied on him doing sex stuff. How many other women were so...sex driven? he wondered.
Helena nibbled her lower lip, thinking of the sexy sounds that had come through the air vent from her mother's room for the last hour. She began to rub her thighs together. "I don't get out much."
Del closed his eyes and rubbed his temples. "Jesus...you're a hot girl that likes anime and sex...you could honestly have any guy you wanted just by showing interest in them, and instead you blackmailed me."
"Soo...you do want to go out with me?"
He looked at her confused but hopeful look. "If you had asked yesterday, I'd have said yes...well, I guess not while I'm 'servicing' your mother..."
"I wouldn't make you stop...that's hot, and I'm not jealous," she informed him, "but why yesterday?"
"Because that was before you blackmailed me!"
"Oh."

"Del?"
He started awake, confused. Where was he? Oh, right, on Helena's bed. She was still in the garters and bustier, so he figured that he'd only been out for a moment. He looked at his phone...it was 9 PM, so he'd been napping there for the last hour. "Were you just watching me sleep?" he asked her.
"You looked like you needed to rest, so I went on my phone for a bit," she replied. "I was hoping a nap might help Mr. Pokey down there."
He considered his penis, but it still seemed devoid of energy. "Hm, probably not."
"What if I...?" She took it in hand and started pulling at it. After a minute of that, she sighed and took it into her mouth.
"Ahh..." he moaned. The warm, inverse pressure felt good, but his cock still remained lifeless.
After another minute she gave up. "Damnit! This is so frustrating. How about...?" She pulled down on her bustier so that her B-cup boobies popped out, each topped with a pink pencil eraser nipple.
Del felt a twinge down below, and licked his lips as he gazed at her luscious tits.
"Yeah?" Helena looked hopeful. "Maybe...?" She moved forward to press a nipple into his mouth, and Del began to suckle on it. "Ooh, that feels...wow..." she moaned. She climbed astride him so that he would have better access to her breasts, which then caused her panty-covered pussy to settle onto his mostly still-soft penis. "Hmm...." she moaned in pleasure and frustration.
"Are those my stockings and garters?"
They froze and turned to the door. Trista was there in her shorty robe, her arms crossed and her eyes narrowed as she beheld her 18-year-old daughter rubbing herself on her 19-year-old boytoy.
"Mom! I, uh..." Helena scrambled off of Del, but that only revealed his half-naked form.
"Del, go home and we'll talk later. Helena, my dear, we are going to have a discussion right now."
He grabbed his pants and bounded past Trista and out of the room. Helena's bedroom door slammed behind him.
