A quickie, for sure!

You pull her more fully onto the bed and yank down on her sweat pants. She squeals and wiggles out of them. She rolls you on your back and straddles you instantly. Before you know it, she's slipped you inside her cunt and is bouncing on you. You pull a tit to your mouth and lick swiftly on the nipple. Jan moans, "Oh, John! I could get used to this." She gasps as you suck hard on the nipple in your mouth and roll the other one in your fingers. Her well-trained pussy muscles are pushing you quickly to a morning orgasm.

Jan shifts her position, releasing her tit from your mouth, and kisses you, her tongue penetrating deep into your mouth. You pound your hips hard up into her as she descends, and she starts keening and moaning in a higher pitch. You lead off today, breaking the embrace to arch your back and groan to the wall behind your head. You explode inside her pussy; she follows suit shortly behind you, an intense pulsing on your shaft. You both quiver and moan through your climax.

She kisses you, disengages from your body and the bed, straightens her tee shirt and pulls up her sweatpants and panties. "Mmmm, having you dripping inside me is going to distract me from my yoga. It'll be good practice." She puts her hand down her pants and brings it out to lick it off. "Yummy. You just taste good. See you later. We can schedule later." Then she runs out the door. You hear a jangling of keys and the front door slamming shut. A wave of more than just tiredness washes over you. You run to the bathroom and then get dressed, leaving off your underwear. You head out of Jan's apartment, locking the door behind you.

The only person you see is a tall, attractive older woman with long brown hair wearing a nurse's uniform. She opens the door to 2C as you're leaving. That must be Joanne, Frank's wife. You wave to her.
