Side Effect (Narry Mpreg)

Intro

Harry was moaning as Niall left love bites on his neck; he looked around getting worried about Niall's wife, Ariana coming home early and catching them. They couldn't risk it anymore.

They've been cheating on their partners since Harry met Niall at a party. He went with his fiancée who was then his new girlfriend Liz, and she showed her to her brother who just so happened to be Niall.

After a few drinks and him talking to Niall things started heating up. They ended up in bed with Niall on top of Harry they didn't do anything sexual; not then anyway as Niall didn't want to take Harry's virginity while he was drunk; but Niall did give him a blow job and Harry give him a sloppy one in return.

It wasn't usual for either of the boys, Harry never really thought about being with a boy at all, and Niall has thought about it but his mom was very against it.

It happened more and more, they never went too far. Not till Harry's one anniversary with Liz, that night Harry lost his virginity in both ways. Having had sex with Liz for the first time in her room and then when Maura made him sleep in Niall's room; having Niall's dick in him making him shake. It was the night Harry fully figured out his sexuality but now that he was too drawn into Liz; there was nothing he could do about it. Especially since Niall was the only boy Harry liked and he never imagined Niall would look at Harry in more ways than just sexually.

That was Harry's biggest regret, never figuring out that Niall did in fact like him how he liked Niall. If Harry knew that; if he was told that he might not be engaged to Liz with a wedding in a month; he might not be secretly having sex with Niall. But here they were. Needing to have this end now.

"I don't think I wanna go father tonight, can you just stroke me off and I'll blow you? Then we can just not touch each other again, and you know keep distance or something."

"Harry you say you want to do that every time." Niall said sitting up as he started stroking his sisters fiancé off, as he whimpered and moaned under him. Once Harry came he got on his knees and started sucking Niall off; Harry had definitely improved on his dick sucking he felt Niall's salty liquid come down his throat and he made sure to swallow every last drop; spitters are quitters.

Once he pulled off he looked at Niall seriously; "I know but this time I mean it; we really need to stop I'm getting married to your baby sister in a month." Harry said getting off Niall's bed and pulling his clothes off before checking to make sure the marks Niall left weren't visible.

"Well I'll see you tomorrow?"

"You wish." Was all Harry responded before leaving. But Niall was right; Harry wasn't going to stop.
