More motherly fun

Ever since the handjob, Caitlin often teased you, although she made it clear she didn't want any escalation.

A few days later, another opportunity presented itself. It was almost midnight when you saw Erin taking some pills.

"Oh hey, sweetie. I couldn't sleep so I need these again. Knocks me right out. Good night!" She left for her bedroom.

Knocks her right out, she said... You waited for half an hour before sneaking into the bedroom. Your father was away on a business trip so Erin was sleeping alone. She was wearing a sexy night gown despite that, and her skirt had ridden up and her lace underwear was in full view.

You gently shook her arm.

"Erin, wake up!" You tried. No response. You tried a few more times before you were sure she was out cold. Perfect. You immediately grab her breasts, the massive mounds that you had long fantasized about. They were as soft as you imagined them to be.

You lose yourself in her huge tits, squeezing, sucking and snuggling on them. Nearly half an hour had passed! You finally change your attention to her lower body. You pull her panties off. You had already seen her naked during the shower, but it was still a mesmerizing sight. You gave it a lick, and when Erin was still fast asleep, proceeded to slurp on her pussy to your heart's desire.

You were incredibly hard at this point. Learning from your mistake, you came prepared this time and fished out the condom in your pocket and slipped it into your huge cock. Nothing was going to stop you this time. You positioned yourself between her legs and slowly penetrated her vagina.

Amazing! It was an entirely different experience from a handjob. Erin was at such a height that in the missionary position your face only reached her chest, which was perfect for you. You squeezed your face in her cleavage and proceeded to thrust away while you inhaled her natural fragrance.

You used her **** body like a sex doll until you came, and even as the intense orgasm tortured you, your hips did not cease thrusting until your balls had expended every drop of semen. When the lust intoxication finally wore off, you found yourself sweaty and panting. With great effort, you got to your feet and cleaned up as well as you could before sneaking away.

Unbeknownst to you, Erin would wake up the next morning with such an intense, burning desire in her loins. With much shame she recalled her dream in which she had sex with her stepson! Even now she felt like her clit was tingling.

"Something must be wrong with me." Erin said. She had to use a dildo to sate her urges, but even after cumming she felt strangely unsatisfied.
