Iris began to move them, with small up-and-down motions.
Fss...
it was already lubricated, so the movement was easy.
"Ugh..."
The sensation made Astan shudder slightly as he felt that softness completely envelop him.
Honestly, he couldn't lie: the sensations and the softness felt really good.
Iris seemed to notice his reaction, and a small smile appeared on her face.
fsss... sckshh... lpsshhh..
Little by little, she began to increase the speed.
Her movements became firmer and more varied, moving beyond the simple up-and-down motion.
She didn't seem to be following any specific pattern.
"Mnngh..."
"Mnngh..."
She was, playing around and having fun at Astan's expense.
Sometimes she applied more pressure; other times, she shifted her movement from side to side to create a different sensation.
At times, she even seemed to be having fun simply using her own weight to increase the pressure.
Fshk... fss... wt-fwt..
Each change produced a different reaction in Astan.
