Group sex with a beautiful girl

"You are going to come for the first time tonight at exactly 12," he whispers.

He hooks two fingers of one hand inside me, right on my G-spot.

His other hand is on my belly so he can press the two together, with his thumb positioned on my clit.

For the first five minutes I giggle, thinking this is all bullshit.

For the next ******* minutes I scream and beg him to let me come, as he edges me with exquisite precision.
