[MMF] My son’s gay lover [Anal] [Incest]

We have two older children, both daughters, who have left the nest. Our son Liam, the youngest,
is a 19-year old community college student still living here with me and Dad.
Liam told us he was gay about 2 years ago, while he was still in high school. He was still a
virgin, he told us, and planned to stay that way until he found “the one”.
Because he had previously dated some female classmates, his dad and I thought
he was bi, or maybe even “straight but curious”. But he insisted he
was gay, and we told him we accepted him no matter how he asserted himself.
Last 2 years was tough for dating, whether you’re gay or straight. Although he
went out sometimes and talked about a boyfriend, we never met him.
 
Until 3 weeks ago.
His dad was out of town. I came home hours earlier than expected and found them “in the
act” in Liam’s bedroom. My son was up on his fours and “the one”
was slowly reaming his butt with a very shiny and well-lubricated dick. I don’t
know why the bedroom door was ajar, but I stood in the hall and watched my son
take it like an experienced anal bottom.
I’d had anal sex myself, twice, when Tom and I were first married, and I’d hated it. We’d never
tried it again. My son, however, was clearly in heaven. I got so aroused
watching them that I said nothing and stayed out of sight, lurking in shadows
in the hallway. My son orgasmed first, his rigid cock bouncing and swinging in
front of him, squirting his ejaculation onto the bed linen. A few seconds later
his lover slammed it home and uploaded his cum deep into my son’s rectum. I
might have cum, too, if I’d had a few more minutes to finger my own wet cunt, but
I scurried away and quietly backed down the hall and downstairs to the kitchen. 
They came downstairs a little later, dressed of course, and were stunned to see me acting
as if I was fixing dinner. Liam had on a robe, and his lover was dressed and
ready to leave. I was briefly disgusted that neither one of them had showered.
Liam stammered something but I cut him off, stuck my hand out, and introduced
myself to his boyfriend, Jason. 
He had quickly regained his poise and said something trite about being pleased to finally meet
me. He then said “I’m sorry we met under these circumstances. It’s a bit
awkward, isn’t it?” 
Before I could
say anything, Liam blurted some nonsense about how Jason was helping him study.
Jason cut him off and said, “She watched us, Liam. She was in the hallway.
She didn’t stop us. It must have kinda turned her on.” 
Now Liam was looking at me. His Mom watched him take a cock? Now he was really lost. 
Jason, on the other hand, knew exactly what he wanted to say. “It turned you on, didn’t
it? Watching your boy get screwed. You could have interrupted, but you just
enjoyed the show. Did you see him cum? I fucked the cum out of Liam, did you
see that?” 
Then he leaned forward and kissed my son right there in front of me. Liam wriggled and
squirmed, uncomfortable with Jason’s outrageous exhibition, but he couldn’t
escape his lover’s embrace. After a few seconds, Liam gave in, and kissed Jason
back enthusiastically. 
I sank slowly into one of the dinette chairs. What the fuck? Jason and Liam were full-on
making out now. Jason started to slip Liam’s robe off of his shoulders. My son,
suddenly resisting again, tried not to be stripped naked in front of his
mother, but Jason was stronger and more determined. The robe ended up a puddle
at their feet as Jason began tugging on Liam’s quickly-erecting dick. 
“He was born to bottom. Your boy can’t help himself. He loves my cock so much, he can’t say no.”
And then Jason turned my son in the other direction and gently bent him over
the table. I couldn’t help looking at his red, puffy anus, and the sperm
leaking down his upper thighs. Jason’s cum. 
Jason slowly fingered Liam’s rosebud and then raised his hand toward me. Look at this, Mom.
Liam’s stuffed full of my cum. I reached my hand towards his, helpless to
control myself, and I touched my extended fingertip to Jason’s. The tiniest
droplet of sperm transferred from his finger to mine. I shuddered with lust and
then leaned over further to touch Liam’s fucked out anus. My finger delicately
circled Liam’s hole. 
“Do it,” Jason urged me. 
I trembled but slowly inserted just the tip of my finger into my son’s ass. Liam was
frantically reaching under himself to flog his stiff cock.
“Do it, slut,” Jason repeated to me, and I went in to the first knuckle. 
Liam was shivering and twitching now, and Jason’s hand took over stroking Liam’s
erection.
“Stuff him,” Jason said, and I gave in and shoved half my finger into my son’s hot, slimy
asshole.
Liam jerked as if an electric shock hit him, and he moaned as he ejaculated all over the kitchen
table where we took our meals. I felt his sphincter clutching my finger,
squeezing tightly and then relaxing. I had an orgasm myself, just a little one
to be sure, but real and unmistakable.
“Come on, Liam’s mom. Let’s take this back upstairs.” And he took my hand and led me
to the large bed in my room. Liam followed behind on rubbery legs. He’d cum
twice in the last hour and I wondered if Jason and I could get any more from
him.
“You’re not going to do that to him again, are you?” I whined to Jason?”
“No, Liam’s Mom. I’m going to do it to you.”
