She rides him.
Hard enough to make her thighs ache and her head swim.
Deep enough that she feels the tip bump her cervix; she can see him, thrusting against her abdomen and it makes her go absolutely carnal.
Grinding on his lap, balls to her ass, she twists her hips to recapture him just right, so her clit scrapes the coarse hair on his pubic bone — she moans, that's fucking good — and he drives along her front wall.
She uses all her energy to milk his cock, clenching around the rock-hard flesh, velvet heat consuming her from the inside and a noise escapes her throat, one of both satisfaction and desperation.
Donna claws at his shoulders, seeking purchase as she bites her bottom lip, letting go and panting hard, bouncing on his lap, clit throbbing and thumping against his pelvis and there it is, spreading like wildfire through her veins, burning across her skin, ablaze in pleasure.
He follows not long after and she continues to take him, all of him, until his cock grows soft and he slips out on the upswing.
She takes the time to relish in their shared ecstasy, slides her folds along his shaft so he can feel it too before dragging her lips across his cheek to meet his open mouth, tongues tangling, noses nudging, legs locking.
