Your wife Olive Glass is tired of your sub par performance in bed and she thinks you need a lesson on how to pleasure her. She wants to show you how to get your cock nice and hard, to last while she pleasures herself, and then cum with her. So she's got some jerk off instructions ready for you to practice with. She knows you like a good visual helper too so she gets naked alongside you, pleasuring her pussy while she tells you how to stroke. Do what she says and if you're good she'll let you cum with her so you both can be satisfied.
