It was barely a week into the first Semester when Michael first brought Lydia home. She was his physics study partner. Mary also noted that she looked like a blond version of her younger self. Michael admitted he'd chosen her for exactly that reason.
Lydia was perky and easy going. Bright, and athletic. She was also, according to Michael a dyed in the wool capital L lesbian.
Coming from a modest background, she was the first kid in her family to attend College and it pretty much strung out the family budget. So, when their study sessions were concluded. Mary would usually have a meal ready and Lydia became like extended family.
She was determined to pull good grades, and seemed laser focused on that. Her girlfriend, on the other hand, came from a well to do family, and seemed to view a college education more as a rite of passage than a valuable privilege. It meant that their relationship was a little over-dramatic at times and fraught with random fallings out.
Lydia gravitated toward Mary as a confidante. And Mary relished it. She'd always wanted a daughter and it seemed that this was as close as she was probably going to get.
Mary and Michael had just finished making love. As always, Mary basked in the pleasured glow, feeling Michael's cum oozing slowly from her pussy.
"Too bad she's gay." Mary said.
"I don't know, Mom. I try not to go there with her. It gets her riled up. Too much drama. I don't think it's a good relationship. I just try to keep her focused on the classwork." Michael said. Kissing Mary one last time and reaching over to turn out their bedroom light.
The holidays were approaching, and Lydia's visits started to become more frequent.
"My girlfriend wants to go to Cancun for Thanksgiving. I really can't afford it. Really can't. We had a pretty bad argument about it." Lydia confessed to Mary.
"I don't know what to tell you. Maybe a little time apart will be good for you both?" Mary offered. "You could stay with us over the holiday?"
"I guess so. I mean, it'd be better than hanging out alone in the dorm." Lydia admitted.
It was a nice, if somewhat muted celebration. Late that Saturday night. Lydia flopped down on the couch next to Mary. She'd obviously had been crying.
"What's up, Lydia?" Mary asked
Lydia handed Mary her cell phone. On the screen was a selfie of Lydia's girlfriend. In the background was someone's leg. It had a rather unique tattoo.
"She's fucking cheating on me." Lydia sobbed. "That's a girl from her dorm."
Mary just hugged the poor girl. Stroking her hair as she began to cry harder.
It was a couple weeks later. Mary was bent over the couch, with Michael's cock fucking her like there was no tomorrow. She was cumming almost constantly. She could tell he was close and began begging for his cum.
"Oh yeah. Cum inside me, baby! Cum inside me!" She groaned as she felt him tense up and release his seed into her. "That's it, baby...soooo good!"
She'd heard a peep from the corner of the room by the kitchen doorway. Lydia had let herself in the back way, and was standing there mouth agape her notebook falling from her hands landing with a plop on the floor..
Michael had pulled free from Mary's quim, a long rope of jizz connected his cock head and Mary's pussy as he extricated his manhood from his Mother.
"Fuck!" was all Michael could manage.
"fuck..." was all Lydia could too, staring at the cum dripping out of Mary's cooter. "I should probably..."
"You should probably sit down." Mary insisted, pulling on her panties and bra and nodding toward the couch.
