As soon as he put his dick inside her pussy he felt a completely different feeling and "It's so cold. But I like it."
If it was any other person he would have already forget about sex but Liam liked it because his body is already very strong and normal ice couldn't hurt him or wouldn't make him feel pain.
On the other hand Lilith immediately moaned as soon as her son dick entered her icy-cold pussy.
Her pussy was cold and her son dick was hot. It feels that in the cold environment only her son could give her heat that she needed.
She felt completely different feeling.
She started moaning because her breasts were groped by him.
Liam didn't wanted to wake up his sister so he took off his hands from her breasts and made her face towards him and started kissing.
Then he placed his hand back on her pussy.
This time Lilith also didn't stopped her moan's and immediately her high pitch moans started coming inside his mouth.
