Go for the bottom.

You run your hand along the inside of her thigh, sliding underneath the underside of her nightie and, then, down between her legs. Warmth and dampness envelops your hand, as you rub her groin.

She leans back, slightly, spreading her legs, giving you full view of her flowering vulva, revealing to you the darker skin of her outer labia, as you work your way into her.

Peeling back those outer lips, you slip your fingers along the pink, wet skin beneath. Clarisa squirms, groping and squeezing her large bosom, as you pushed two of your fingers deep into her moist tunnel.

Slowly, you start sliding your fingers in and out of her. Groaning, she bites down on her knuckle, as you pick up pace and begin rubbing her clitoris with your thumb.

Feeling you playing with it, she starts to squirm more, her breathing becoming rapid and she starts letting out the occasional deep, sensual moan.

Suddenly, she closes her legs, trapping you inside her. Arching her back, she lets out a sigh and you feel the contractions of her orgasm through your hand, as she cums.

After a few minutes, she raises back up into a seating position on your lap, now, holding you in her arms.

Deciding to send her to bed, you send the energy once again into her. This time it was barely noticeable.

With a tender kiss, she left the room, heading back upstairs.
