Step son fucks stepmom while she is resting

When stepmom didn't resist, my courage increased a little. I placed my hand between her thighs, right on top of her pussy. She had her legs crossed in such a way that the entrance to her pussy was still closed. My lust was consuming me. After about two minutes, stepmom turned over, revealing her face. My hand was now firmly entangled between her legs, causing stepmom's pussy to open. Because stepmom wasn't sure what to do, I quickly removed my hand from her legs and placed it on her ass. Because the mattress was small, when stepmom turned over, her knees and mine touched. All this made my cock swell. I was fondling stepmom's pussy over her thong. Just then, stepmom said in a low voice, "Won't you fuck me?" Hearing this, I was initially shocked, but then I quickly removed the sheet and pulled my mother over me, laying her down on top of me.
