Ianto didn't bother holding back in kissing Sulu back. Yes, it was a little weird, but that wasn't going to stop him now. He was pretty sure that he was blushing pretty heavily as well, because well. With Sulu laying on top of him he could feel Sulu's newly re-acquired breasts pressing against him. The difference now, though, was that they were pressing up against his own, and it felt...well. Nice. Soft. Pretty drastically different than how things were usually with Sulu, and it'd been such a long time since he'd been with a woman at all that he was flustered either way. But still kissing back.

He shifted slightly underneath Sulu, before cautiously putting a hand up to rest on the side of his waist, his other hand going to cup his face as he angled the kiss for a better position there too. Alright, so far, not bad. Ianto ran his thumb over the fabric of Sulu's t-shirt that he'd worn to bed, where his shirt lay, sighing happily into the kiss. Not bad at all.
