Yes, and her mom

With a challenge like that, how can you fail? You reach up and pinch Lynn's nipple with one hand and put your thumb from the other hand on her clit.

"Oh, God! Yes!" cries Lynn. Her body gyrates erotically, and she increases the pace on finger-fucking her mother. Her other hand is still squeezing her other tit. You pick up the pace on thrusting into her very willing body. Lynn's pussy is tight, but very slippery, so you have no trouble fucking her hard. The sight of her writhing, sex-crazed body and the incestuous lesbian sex has your lust in overdrive. Her noises of ecstasy get higher in pitch, and Jill is keening as well.

Since you have had an orgasm recently, you are not in danger of going too soon, so you pump faster into her cunt. Your dancing thumb, the slightly painful pinching on her nipple, and your plundering cock all make Lynn groan and whimper.

An outburst from Jill takes your attention away from lynn for a second. You watch her body quake and undulate as her orgasm takes over. "Oh, God! Yes! I'm cumming!" she shouts triumphantly. A squeal escapes her throat just before a low groan.

The second voice in this symphony hits a high note as Lynn's cunt clamps down tightly on your cock. She gibbers and writhes, impaled by your shaft. Wave after wave rolls up her body, shaking her tits in an erotic wobble. Her climax feels amazing on your flesh, but you manage to hold off on your orgasm. You have other plans.
