Time for that later. Grace has ideas

Grace collapses on your body as her shudders subside, panting softly as her trembling flesh quakes through the aftershocks of her orgasm.

"Oh God, I don't believe it," she purrs. "That was so good...so fucking incredible." She squirms against you, her mouth nuzzling your skin happily.

Your heart is still hammering in your chest and there is a dull but satisfied ache in your cock and balls. You're still inside her, but rapidly softening, your meat exhausted from the efforts of the last hour.

"You're the incredible one," you tell her, kissing the top of her head. "you got me going three times."

"Mmmmmm and the last one was the best," she murmurs. "I just kept coming and coming and coming. I've never done that before. I thought I was going to die it was so good." She giggles softly and kisses your throat again, then lifts her head and squirms forward to kiss you on the mouth with lazy hunger.

As you kiss, you hold her and roll onto your side, getting her weight off you. She breaks the kiss and strokes your face, looking up into your eyes with happiness.

"I want to stay here," she says with a sultry giggle. "I want to stay here and make love all afternoon. I want you to show me everything. I want you to make me come like that again and again."

You give a rueful laugh and kiss her again. "I'm not a young man, Grace. I'm not sure I'm up for that."

"Mmmm you already did it twice in a row, that's more than Lance could do," she states firmly, touching the chain at her wrist with a flick of a finger. "Most times he was done before I was even close, and he'd get mad if I tried to finish myself." She blushes prettily. "I almost came when I was blowing you. I loved looking at you and knowing how much I was exciting you. I do excite you, don't I Mr. Carter?" she asks in a tone of teasing softness.

"Very much Grace, very much indeed. Maybe while we're like this you should call me Mason instead of Mr. Carter."

"No. I want you to be Mr. Carter. My teacher. Who is teaching me all about biology," she giggles lewdly, wriggling against you and hooking one of her heels behind your knee. "You will keep teaching me, won't you Mr. Carter?"
