Walked in on my 2 uni flatmates and joined in

In our first year uni flat, we pretty much had an open door policy and it was made obvious quickly that we were all very sexually active. Steph and Hannah had always joked about doing stuff with each other, just to try it, so I guess one night they just went with it, I came back in from uni and I could hear moaning, I drop my bag in my room and I look into Hannah’s room, she’s there on the bed with Steph, kissing and Steph is fingering her. They both just laugh when I come in and carry on. I stand there and watch for a second, it got me rock hard, Steph kept looking over at me and then took her hand away from Hannah’s pussy to usher me over. She tells me to take my dick out and for Hannah to suck it. While she does that, Steph goes down on Hannah. I then take my dick out of Hannah’s mouth and tell Steph to get on her back, I fuck Steph while Hannah straddles her face, next Hannah licks Steph’s pussy while I fuck Hannah.

I’ll be honest, I wanted to finish in or on Hannah, I get her in prone bone and fuck her while Steph masturbates and watches. Steph and Hannah lock eyes when I cum inside her. When I pull my dick out of Hannah, Steph spreads Hannah’s cheeks and takes one long lick of her cum covered pussy and Hannah sucks my dick.

Later that day, Steph comes into my room, lies on my bed, takes her shorts off and just goes ‘and now you’re going to fucking cum in me’.
