Head home and get ready for bed

The two of them finish dinner and head home. His mom asks, "Do you feel alright John? You were so quiet at dinner. I hope I didn't upset you talking about your friend Maria like that."

John answers her, "No, I'm just tired I'm going to head right to bed when I get home."

John headed up to his room and pull off his clothes. He can hear Juliet in the shower and his big cock stiffens into a hard boner as he think about his sister's big tits with the water running over them, her nipples hardening into stiff points as she washes them with her soapy hands. He grip his cock and start to slowly jerk up and down the shaft thinking about how he would like to slide his cock into his sister's tight cunt, or fuck her big tits. He wander over to where his computer is on and he see he have a message waiting. The message is from Maria, the opening line is, "Is your cock hard?"

John sits down and sends a quick message back to her, "Rock hard thinking about your tits."

She shot right back, "I'm rubbing my nipples right now making them big and stiff. My pussy is soaking wet, should I touch myself? How about you, are you jerking off?"

The impersonal computer screen made him bold and he let her know exactly what he were thinking, "Yeah, I'm beating off thinking about sliding my cock inside you."

"That sounds good; my pussy is nice and wet. What would you like me to do now? What would turn you on, would you like me to finger fuck myself, or play with my tits some more?"

John fires back a quick response, "Finger fuck for me. Pretend my cock is slamming into your pussy. Pretend my cock is making you cum." The nasty thoughts fill his mind and flow onto the screen with a life of their own.

"Mmmm, I'm sliding my finger inside my fuck hole. I am thinking about your cock thrusting inside me. Mmmm, I wish you were here to fuck me with your big cock. Are you going to blow your load?"

John realizes that he is real close to cumming and he jack off slowly as he read her response. He finds that he entering a kind of sexual trance. He starts to type his response back to her, "Yeah, finger fuck yourself for me, make …"

However, he never finishes, for then he hears his Mom's voice, "John are you feeling better…, Oh my!"

John jumps up his big boner poking out in front of his naked body and he sees his mom looking at him through the bedroom door. He realizes too late that he forgot to lock the door. He lowers his hands to his crotch trying to cover his big, thick cock. John sees his mom's eyes drift down to his cock.
