Jerk it for me daddy (läxhjälp med Marie McCray)

Marie needs some help with her homework. Do you know what ejaculatory contractions are? Oh, you do? Then it looks like you can give your stepdaughter a little help. You take out your penis so that she can see what one looks like in real life. You tell her that you have to stroke your penis so that it can get hard. Marie is puzzled. You keep stroking it until stuff comes out of it? She needs to learn, though, so she goes along with it. Thinking that seeing her tits might be helpful in the process, she removes her bra to reveal her big, perky tits. You tell her that you want to see more, and she serves. Her shorts slide down onto the floor, soon followed by her panties. She stand before you totally nude and she serves as fine inspiration for your homework session. To further learn from your time together, Marie takes your cock in her hand and she strokes it gently. Are you getting close?
