I started moving again, this time with no restraint at all. My hips slammed into hers and the sound of skin on skin echoed through the room alongside her increasingly loud moans. From this angle I could go deeper, could hit spots that made her cry out with every thrust.
Diane’s arms gave out completely and she pressed her face into the mattress, her fingers twisted in the sheets as I fucked her from behind. Her ass bounced with every impact and I couldn’t help reaching out to grab it, my fingers digging into the soft flesh.
"Yes," she gasped into the sheets. "God yes, just like that—"
Behind us Sloane was watching with wide eyes, her hand still working between her legs. When our eyes met she didn’t look away, didn’t stop touching herself. She just watched me fuck her mother with an expression that was pure hunger.
The sight pushed me closer to the edge.
I leaned over Diane’s back, changing the angle again, and she made a sound that was almost a sob. Her pussy was getting tighter, her body tensing in a way that told me she was close again.
"Come," I ordered. "Come for me again."
"Can’t," she whimpered. "Too much, I can’t—"
"Yes you can." I reached around to find her clit again, rubbing it in time with my thrusts. "Come."
And she did.
Her second orgasm hit even harder than the first, her whole body shaking as she came around me. The sensation of her clenching around my cock was too much to fight and I finally let myself go, burying myself deep as I came inside her.
The pleasure was so intense it almost hurt, every nerve ending firing at once as I emptied myself into her. Diane was still trembling beneath me, small aftershocks running through her body, and when I finally stopped moving we both collapsed onto the mattress in a tangle of limbs.
For a long moment the only sound in the room was our ragged breathing. Then Diane laughed, the sound exhausted and genuinely happy.
"Well," she said. "That was unexpected."
I pulled out of her slowly and rolled onto my back beside her, staring at the ceiling while my heart rate tried to return to normal. "You started it."
"I did." She turned her head to look at me, her expression soft. "I’m not complaining."
Sloane appeared in my peripheral vision, climbing onto the bed on my other side. She was still flushed and breathing hard, and when I looked at her she bit her lip.
"That was," she started, then stopped. "I don’t have words for what that was."
"Hot?" Diane supplied helpfully.
"Understatement." Sloane’s hand found mine and squeezed. "I want to try that. The thing where you just—took over. Can I try that?"
My brain was still mostly offline but I managed to nod. "Give me like five minutes."
"Boundless Stamina," Diane said, her voice amused. "You won’t need five minutes."
She was right. My body was already responding, already getting ready for round two despite having just finished. The Sexercise trait was probably kicking in too, feeding off the encounter to push my stats higher.
I was going to be a monster by the time we finished.
Sloane noticed the same thing Diane did because her eyes went wide. "How are you already—that’s not normal."
"Nothing about this is normal," I pointed out.
She laughed and leaned down to kiss me, her lips soft and sweet against mine. When she pulled back her expression was determined.
"My turn," she said. "Show me what you just did to her."
